Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically to pneumatic technology. Background Technology

[0002] Traditional pneumatic rotating equipment basically comes in only two types: one is driven by variable volume air pressure, such as twin-screw compressors and piston compressors; the other is driven by high-speed airflow impacting blades, such as steam turbines and turbines.

[0003] Both types of pneumatic drive devices contain power components that move relative to each other and require airtight fit. As a result, they both suffer from problems such as complex structure, high failure rate, high cost, short lifespan, and the need for frequent maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a thrusting device with a bending expansion thrust channel to solve at least one of the above-mentioned technical problems.

[0005] The technical problem solved by this invention can be achieved by the following technical solutions: A rotary device with a curved expansion thrust channel includes a rotatable rotating carrier, characterized in that the rotating carrier is provided with an air intake channel; The direction of gas flow is used as the reference for internal and external orientation positioning. The intake channel has a passage for airflow, which serves as a channel for bending expansion thrust. The flow area of ​​at least one section of the curved expansion thrust channel gradually increases from the inside to the outside; At least one section of the curved expansion thrust channel extends outward from one end near the intake channel and bends in one direction.

[0006] The bending expansion thrust channel has an inner wall on the side away from the axis of rotation, which is called the torsion wall.

[0007] The intake passage connects to an outlet that begins to expand, called the injection port.

[0008] The connection between the nozzle and the curved expansion thrust channel can be smooth and seamless, without strict regional division.

[0009] A structure equipped with an air intake passage and an injection port is called an injection structure.

[0010] The flow area of ​​at least one section of the curved expansion thrust channel gradually increases from the inside to the outside, providing space and expansion guidance for the continuous expansion of the pressurized gas. In the curved expansion thrust channel, the gas continuously expands, and its momentum increases, continuously providing rotational momentum and rotational kinetic energy to the rotating carrier.

[0011] The most difficult, complex, costly, and easily damaged parts of traditional rotating gas energy conversion equipment are the relatively moving and stationary components.

[0012] For example, the moving plate and stationary plate of a steam turbine, the piston and piston cylinder of a piston machine, the volute and scroll of a turbine, and the screw and casing of a screw compressor.

[0013] Compared to gas energy conversion devices that generate rotation, such as steam turbines, piston machines, turbines, and screw compressors, this invention does not have moving or stationary parts with relative motion. It also has many advantages, such as simple structure, small weight, virtually no upper limit on single-unit power, low cost, not easily damaged, and low requirements for gas quality.

Detailed Implementation

[0016] To make the above-mentioned objects, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1-8 As shown, the push-rotating device with a bending expansion thrust channel includes a rotatable rotating carrier 7, characterized in that the rotating carrier 7 is provided with an air intake channel 12. The direction of gas flow is used as the reference for internal and external orientation positioning. The intake passage 12 is connected to a channel for airflow, which serves as a bending expansion thrust passage 13; The flow area of ​​at least one section of the curved expansion thrust channel 13 gradually increases from the inside to the outside; At least one segment of the curved expansion thrust channel 13 extends outward from one end near the intake channel 12 and bends in one direction.

[0018] The intake passage 12 is connected to an outlet that begins to expand, called the injection port 3.

[0019] The injection port 3 is a definition used for position division; it is an opening structure that does not require a clearly defined location. The docking between the injection port 3 and the bending expansion thrust channel 13 can be a smooth, seamless connection, without strict area division. The structure equipped with the air intake channel and the injection port is called the injection structure 1.

[0020] The bending expansion thrust channel 13 has an inner wall on the side away from the rotation axis, called the torsion wall 5.

[0021] The flow area of ​​at least one section of the curved expansion thrust channel 13 gradually increases from the inside to the outside, providing space and expansion guidance for the continuous expansion of the pressurized gas. In the curved expansion thrust channel 13, the gas continuously expands, and its momentum increases, continuously providing rotational momentum and rotational kinetic energy to the rotating carrier 7.

[0022] The most difficult, complex, costly, and easily damaged parts of traditional rotating gas energy conversion equipment are the relatively moving and stationary components.

[0023] For example, the moving plate and stationary plate of a steam turbine, the piston and piston cylinder of a piston machine, the volute and scroll of a turbine, and the screw and casing of a screw compressor.

[0024] Compared to gas energy conversion devices that generate rotation, such as steam turbines, piston machines, turbines, and screw compressors, this invention does not have moving or stationary parts with relative motion. It also has many advantages, such as simple structure, small weight, virtually no upper limit on single-unit power, low cost, not easily damaged, and low requirements for gas quality.

[0025] The operating mechanism of the thrust device with the curved expansion thrust channel of this invention does not rely on the Carnot cycle. Effective thrust can be generated as long as the airflow has a higher relative velocity or acceleration than the curved expansion thrust channel 13. Furthermore, the starting point of the airflow is synchronized with the curved expansion thrust channel 13. Under many conditions, more energy of the airflow can be converted into kinetic energy, and the energy surplus of the exhaust airflow at the exhaust port 4 can be reduced. At normal temperatures, it has the potential to exceed the operating efficiency of the Carnot cycle.

[0026] The structure of this invention employs a curved expansion thrust channel 13, which utilizes a throttling effect to cool the exhaust gas from the curved expansion thrust channel 13, converting internal energy into kinetic energy during the cooling process.

[0027] When using a high-temperature, high-pressure gas source, especially when using combustion gas, the airflow temperature in contact with the curved expansion thrust channel 13 is lower, making it easier to protect the power components (curved expansion thrust channel 13).

[0028] During operation, this invention exhibits significant airflow cooling and a clear effect of converting thermal energy into rotational mechanical energy.

[0029] Furthermore, compared to traditional equipment, the airflow temperature is lower and it is less likely to dissipate heat to the outside, which is conducive to generating higher energy conversion efficiency. Especially when using a normal temperature or low temperature pressure air source, the outlet air temperature of the curved expansion thrust channel 13 will be even lower, even far below the ambient temperature, making it easier to absorb heat from nature for further expansion and generate more thrust energy for the curved expansion thrust channel 13.

[0030] Unlike the forward thrust of turbines and steam turbines, this invention operates at a much lower airflow velocity at the exhaust port 4 compared to steam turbines and steam turbines, allowing more of the airflow's energy to be converted into kinetic energy.

[0031] When a steam source is used to supply air to the intake channel 12, the temperature of the exhaust port 4 can be close to or even lower than 100 degrees Celsius through structural design.

[0032] Compared to steam turbines and turbines that use steam as their source, it has a much lower outlet temperature and higher energy conversion efficiency without requiring a condenser pump.

[0033] This invention also differs from the recoil mechanism of rocket engines and jet engines. Rocket engines and jet engines provide power based on projectile recoil, which results in low efficiency when the rocket is running at low speed.

[0034] Rocket engines and jet engines have very short jet cowlings, and a large portion of their thrust comes from the exhaust gas (tail flame), which expands externally to generate thrust. Relying on high-velocity (typically supersonic, or even more than 10 times the speed of sound) exhaust gases, their energy utilization is relatively low and they generate a lot of noise.

[0035] This patent features an innovative design for a bending expansion thrust channel 13.

[0036] This invention utilizes a curved expansion thrust channel 13 to provide a curved and continuous expansion space. The continuous expansion of the gas within the curved expansion thrust channel 13 provides a reaction force to achieve propulsion. It does not rely on high-speed pressurized exhaust gas, which can greatly reduce the influence of the external environment. Even when running at low speeds, it has high efficiency and significantly reduced noise.

[0037] The basic operating mechanism of rocket engines and jet engines is to eject airflow at the highest possible speed.

[0038] This invention utilizes the curved expansion thrust channel 13 to provide resistance for the direct expansion of the airflow (gas), making the ejected airflow tend to be gentle and independent of the high-speed airflow. This is completely different from, and even diametrically opposed to, the operating mechanism of rocket engines and jet engines.

[0039] In addition, the bending expansion thrust channel 13 is bent in a clockwise direction, which has the following technical effects: First, it gives the airflow centrifugal force, increases the channels for outputting energy through centrifugal force, and improves thrust and energy conversion efficiency; Secondly, it hinders the expansion of pressurized gas, significantly reducing the expansion speed of the airflow and improving energy release efficiency. Third, while the space occupied by the curved expansion thrust channel 13 is greatly reduced, the reverse resistance (wind resistance) that may be generated during rotation is greatly reduced through the curved structure.

[0040] It has many advantages such as simple structure, low cost, stable performance and long service life, low requirements for gas purity, high energy conversion efficiency and low noise.

[0041] The rotating carrier 7 is equipped with a rotatable rotating joint 14.

[0042] The rotating carrier 7 and the rotating joint 14 tend to be on the same rotation axis.

[0043] The rotary joint 14 is rotatably connected to an external pressurized air source, which directly provides pressurized gas to the air intake channel 12.

[0044] The rotary joint 14 is rotatably connected to an external fuel source to provide fuel to the rotating carrier 7. After the fuel is burned, it indirectly provides pressurized gas to the intake passage 12.

[0045] From the perspective of the rotation axis of the rotating carrier 7, the injection direction of the air intake channel 12 is clockwise, and the flow direction of the curved expansion thrust channel 13 is also clockwise.

[0046] For example, the injection direction of the intake channel 12 is clockwise, and the flow direction of the curved expansion thrust channel 13 is clockwise. This drives the rotating carrier 7 to rotate counterclockwise.

[0047] This ensures that the thrust generated by several stages proceeds in a clockwise direction, thereby accumulating into a stronger thrust.

[0048] The rotating carrier 7 has a rotating shaft, and the intake channel 12 and the curved expansion thrust channel 13 are connected to form a curved pipe that surrounds the rotating shaft on the inside.

[0049] First, it helps to achieve continuous and long-lasting torque (thrust) output; second, it balances the thrust in all directions of the rotating shaft to make the rotation smooth.

[0050] The curved expansion thrust channel 13 has an opening at its outer end, called the exhaust port 4; The cumulative change angle of the torsion curve of the curved expansion thrust channel 13 from one end of the intake channel 12 to the exhaust port 4 is greater than 90 degrees.

[0051] One case in which the cumulative change angle of the torsion curve is greater than 90 degrees is when the torsion of the bending expansion thrust channel 13 is less than one circumference, and the angle between the orientation of the intake channel 12 and the orientation of the exhaust port 4 is less than 360 degrees.

[0052] In another scenario, the torsional curve of the curved expansion thrust channel 13 is greater than a full circle, meaning the curved expansion thrust channel 13 can rotate several times around the axis of rotation. In this case, the angle cannot be defined by the angle between the orientation of the intake channel 12 and the exhaust port 4; instead, it must be defined and described by the cumulative change in angle of the torsional curve.

[0053] The bending expansion thrust channel 13 has a torsional curve greater than a circle on a plane.

[0054] Larger, flatter structures generate greater thrust.

[0055] It facilitates equipment layout in flat, spacious environments.

[0056] The curved expansion thrust channel 13 has a torsion curve greater than one circle, forming a spiral upward structure.

[0057] The slender structure generates greater thrust. It also facilitates equipment layout when there is ample space along the length.

[0058] First, it further achieves continuous and long-lasting torque (thrust) output; second, it more balanced the thrust in all directions of the rotating shaft to make the rotation smoother.

[0059] The air intake passage 12 has a passage whose flow area gradually decreases from the inside to the outside; The end of the air intake passage 12 with a smaller flow area has an outlet, which serves as the injection port 3.

[0060] By contracting the flow area of ​​the intake channel 12 and expanding the flow area of ​​the bending expansion thrust channel 13, the gas velocity over a short distance is increased. This reduces the size of the equipment while facilitating the increase of gas velocity to supersonic speeds in the initial section, thereby improving energy conversion efficiency.

[0061] On the side of the curved expansion thrust channel 13 away from the rotation axis, there is an opening that connects to the outside world, called the opening channel 6; The opening channel 6 connects the inner and outer sides of the bending expansion thrust channel 13; the opening of the opening channel 6 in the bending expansion thrust channel 13 is located at least behind the middle of the bending expansion thrust channel 13.

[0062] The external airflow velocity drawn into the opening channel 6 is lower than the airflow velocity in the curved expansion thrust channel 13. After being drawn in, it is accelerated, which in turn generates reverse thrust or resistance for the airflow in the curved expansion thrust channel 13, thereby generating rotational thrust for the curved expansion thrust channel 13.

[0063] In this embodiment, the beneficial effects of drawing in external airflow through the opening channel 6 are as follows: First, the internal airflow inside the curved expansion thrust channel 13 is used to accelerate the external airflow and generate a counter-thrust. Secondly, the suction force of the open channel 6 on the external airflow is used to further generate torque; Third, it utilizes the inhaled external airflow to complete the heat exchange with the internal airflow.

[0064] All of the above have the effect of promoting energy conversion and improving efficiency.

[0065] Further optimization involves utilizing impact force to generate thrust while avoiding reverse drag force and reducing torsional strength.

[0066] The bending expansion thrust channel 13 increases the expansion amplitude after the opening channel 6.

[0067] The increased expansion of the rear-section bending expansion thrust channel 13 facilitates better technical performance.

[0068] In this embodiment, while generating thrust, it avoids generating reverse drag force and thus avoids reducing torsional force.

[0069] Further optimization involves the external opening of the opening channel 6 facing the rotation direction of the bending expansion thrust channel 13, and the flow direction of the opening channel 6 being along the airflow direction of the bending expansion thrust channel 13.

[0070] In this embodiment, the airflow is made smooth to facilitate gas inflow.

[0071] The bending expansion thrust channel 13 has an inner wall on the side away from the rotation axis, which is called the torsion wall 5; The bending expansion thrust channel 13 has an inner wall on one side near the rotation axis, which is called the auxiliary rotating wall; In addition, two shielding walls 11 are provided to cover the upper and lower sides of the torsion wall 5 and the auxiliary torsion wall; The torsion wall 5, the auxiliary torsion wall, and the two shielding walls 11 form at least one section of the curved expansion thrust channel 13.

[0072] In this embodiment, a portion of the airflow near the auxiliary rotating wall moves toward the torsion wall 5 under centrifugal force, reducing the pressure near the auxiliary rotating wall; by increasing the pressure difference between the torsion wall 5 and the auxiliary rotating wall, the torsion force is increased, thereby increasing the energy output efficiency and power.

[0073] The pressure decreases near the auxiliary rotating wall, the airflow velocity increases, and the centrifugal force increases, causing the airflow to continue moving towards the rotating wall 5, converting the energy of the increased velocity into mechanical kinetic energy.

[0074] The above structure reduces the pressure on the auxiliary rotating wall, and can even generate negative pressure.

[0075] The distance between the twisting wall 5 and the auxiliary twisting wall gradually increases from the inside to the outside. The angle formed between the two shielding walls 11 from the inside out is less than 10 degrees.

[0076] First, by limiting the expansion of the included angle between the two shielding walls 11, the expansion of the airflow in the vertical direction is restricted, thereby concentrating more of the thrust generated by the expansion and improving efficiency.

[0077] Secondly, it simplifies the structure, saves costs, facilitates manufacturing and maintenance, and improves space utilization.

[0078] The rotating carrier 7 has a circular cross-sectional profile.

[0079] It facilitates the integration of the bending expansion thrust channel 13, reduces manufacturing costs, and lowers air resistance.

[0080] At least one segment of the rotating carrier 7 can be disc-shaped.

[0081] Simplify the structure to reduce manufacturing costs.

[0082] Alternatively, at least one segment of the rotating carrier 7 may be cylindrical.

[0083] Increase the cumulative length of the bending expansion thrust channel 13 carried by the entire system in a single rotating carrier 7.

[0084] Multiple bending expansion thrust channels 13 can be arranged in a cylindrical shape.

[0085] A spirally ascending curved expansion thrust channel 13 can also be arranged in the cylindrical shape, and the torsional curve of the curved expansion thrust channel 13 is allowed to be greater than one circumference.

[0086] It helps to generate greater thrust (torque).

[0087] The overall angle refers to the angle presented from a visual perspective, including the average angle between the jet direction and the curve (surface) it points to. The tangent between the jet direction of the intake channel 12 and the tangent of the curved curve of the torsion wall 5 it points to is set on the inner side to present an obtuse angle structure greater than 120 degrees and less than 170 degrees. This is derived from actual testing and simulation, ensuring smooth airflow from the intake channel 12, facilitating airflow acceleration within the intake channel 12, while also ensuring a short energy conversion stroke within the centrifugal force, a reasonable length of the torsion wall 5, and high efficiency.

[0088] Furthermore, at the connection between the torsion wall 5 and the air intake channel 12, the tangent of the curvature of the torsion wall 5 tends to be consistent with the injection direction of the air intake channel 12, and the angle difference between the two is less than 10 degrees.

[0089] In this embodiment, the jet direction of the present invention refers to the direction of the jet airflow generated in a stationary state without the torsion wall 5 acting as an obstruction. This design ensures smooth airflow jetting, and while generating a high flow velocity, it also provides significant inertial and centrifugal forces that continuously act on the torsion wall 5, thereby improving power and efficiency.

[0090] Furthermore, the air intake passage 12 has a sufficiently small cross-section to allow the ejected gas to reach supersonic speeds.

[0091] In this embodiment, increasing the airflow velocity to supersonic speed enhances centrifugal and inertial forces, which facilitates the conversion and release of internal gas energy, thereby increasing power and efficiency. Furthermore, increasing the airflow velocity to supersonic speed allows for the generation of a higher exhaust velocity at the exhaust port 4, which facilitates the generation of recoil force and further increases power.

[0092] Furthermore, the air intake passage 12 has a flat opening structure; The flat-mouth structure has both a width direction and a length direction; The length direction corresponds to the direction of the distance between the two shielding walls 11 at the connection point; The width direction corresponds to the direction of the distance between the torsion wall 5 and the auxiliary torsion wall at the connection point; The length of the flat-mouth structure is more than three times its width.

[0093] In this embodiment, the advantages are twofold: first, under the premise of comparable airflow, more airflow can approach the torsion wall 5 and generate energy conversion; second, under the same thrust, the volume, structure, and cost can be greatly reduced. With the same efficiency and exhaust volume, by adjusting the length of the flat-mouth structure, one device using a flat-mouth intake channel 12 can be equivalent to five or even more devices using round-mouth intake channels 12.

[0094] Furthermore, the width of the rear section of the air intake channel 12 is 0.5mm~10mm, the length of the air intake channel 12 is 1.5mm~30mm, and the length of the air intake channel 12 is 5~30mm.

[0095] In this embodiment, the depth direction is relatively narrow among the above parameters. The narrow orifice design can compress the gas to a higher pressure, so as to generate greater thrust at the injection port 3; while the width direction is extended to accommodate more gas to enhance thrust.

[0096] The parameters mentioned above are generally applicable to the properties of conventional metals. Furthermore, they enable relatively ideal energy conversion within a suitable volume.

[0097] The air inlet of the air intake channel 12 is called the air gathering port 2. The flow area of ​​the channel behind the air gathering port 2 gradually decreases from the inside to the outside.

[0098] The converging air inlet 2 helps accelerate the airflow within the intake passage 12. When used in conjunction with the expanding, curved thrust passage 13, it allows the airflow to reach higher speeds, even several times the speed of sound, within the curved thrust passage 13, thus improving efficiency and power.

[0099] Reference Figure 2 , Figure 6 , Figure 8As shown, there is a rotating carrier 7 that is pushed around, and an air intake channel 12 is disposed in the rotating carrier 7; the injection direction of the air intake channel 12 is deflected outward relative to the direction of the rotation tangent of the air intake channel 12.

[0100] It adapts to gas flow compensation at high speeds, thereby improving efficiency.

[0101] In this embodiment, the beneficial effects are that it improves the smoothness of air outlet 3, increases the airflow velocity at the outlet 3, and improves power and efficiency.

[0102] Furthermore, the curved expansion thrust channel 13 expands the flow area outward based on the flat opening structure of the injection port 3.

[0103] Furthermore, at least one section of the curved expansion thrust channel 13 has an expansion angle of 15 to 60 degrees relative to the torsion wall 5 and the auxiliary torsion wall in the flow direction.

[0104] The expansion angle can be the angle between the tangents of the relative torsional wall 5 and the auxiliary rotating wall at the same distance from the rotation axis.

[0105] In this embodiment, the expansion angle of the two opposing inner walls of the curved expansion thrust channel 13 forms a fan-shaped spray state, and the degree is limited to between 15 and 60 degrees. Its beneficial effect is that it can release gas faster and more, and considering the curved structure of the curved expansion thrust channel 13, it provides a reasonable curve process for gas expansion, thereby making the injection efficiency higher and generating greater thrust.

[0106] Furthermore, the torsion wall 5, starting from one end near the intake passage 12, has at least two sections: a front torsion wall and a rear torsion wall. The bending structure of the torsion wall 5 undergoes at least one change at the connection between the front torsion wall and the rear torsion wall; The outward expansion at the connection point is greater than that of the preceding torsional wall.

[0107] In this embodiment, the connection between the front and rear torsional walls is an outward steep slope. During the transition from the front to the rear torsional walls, the airflow expands outward more significantly after the connection, creating a low-pressure zone. The airflow releases the pressure generated by the compression of the front torsional walls, resulting in an acceleration towards the low-pressure zone and a thrust on the rear torsional walls.

[0108] Further optimization resulted in the front torsion wall being longer than the rear torsion wall.

[0109] In this embodiment, for a segment of airflow, the relatively long and stable pressure output from the front section of the torsional wall is utilized, while the relatively short rear section of the torsional wall generates a pressure-reducing and speed-increasing impact force. Its beneficial effects are: One is to output more energy while ensuring that the torsion wall 5 is not too long.

[0110] Secondly, by increasing the airflow cross-sectional area of ​​exhaust port 4, the recoil force or reverse momentum is increased, resulting in the output of more energy.

[0111] Reference Figure 3 , Figure 4 , Figure 5 As shown, the torsion wall 5 is provided with an opening channel 6; the opening channel 6 connects the inner side and the outer side of the torsion wall 5; the opening of the opening channel 6 on the inner side of the torsion wall 5 is located at least after the middle of the front section of the torsion wall.

[0112] In this embodiment, the beneficial effects of drawing in external airflow through the opening channel 6 are as follows: First, the internal airflow inside the torsion wall 5 is used to accelerate the external airflow and generate a counter-thrust. Secondly, the suction force of the open channel 6 on the external airflow is used to further generate torque; Third, it utilizes the inhaled external airflow to complete the heat exchange with the internal airflow.

[0113] All of the above have the effect of promoting energy conversion and improving efficiency.

[0114] Further optimization involves utilizing impact force to generate thrust while avoiding reverse drag force and reducing torsional strength.

[0115] The above arrangement is conveniently achieved at least in the front section, where the expansion of the rear torsion wall is relatively large.

[0116] In this embodiment, while using impact force to generate thrust, the reverse drag force is avoided to prevent a reduction in torsional force. Based on the fact that the rear section of the torsional wall has a larger expansion range, the above arrangement is conveniently achieved.

[0117] Further optimization involves the flow direction of the opening channel 6 being along the airflow direction of the torsion wall 5.

[0118] In this embodiment, the airflow is made smooth.

[0119] Reference Figure 7 , 9 As shown, the air intake passage 12 and the bending expansion thrust passage 13 are assembled on a rotating carrier 7; The rotating carrier 7 has a cavity with gas pressure-bearing capacity; The air inlet 2 is located in the inner cavity 8 of the cavity, and the air inlet channel 12 and the curved expansion thrust channel 13 form a conductive structure that penetrates the cavity wall; The bending expansion thrust channel 13 is located on the outside of the cavity.

[0120] In this embodiment, the cavity provides pressurized gas to the gas collection port 2, and the pusher device with a curved expansion thrust channel provides rotational (torsional) thrust to drive the rotating carrier 7 to rotate.

[0121] Furthermore, the interconnected air-gathering port 2, air intake channel 12, injection port 3, and curved expansion thrust channel 13 form a thrust mechanism; At least three pushing mechanisms are arranged on the rotating carrier 7; Furthermore, the rotation direction of at least three rotating mechanisms is consistent.

[0122] Reference Figure 7 The rotating carrier 7 has a cylindrical structure; At least three pushing mechanisms are stacked along the length of the cylindrical structure.

[0123] The exhaust ports 4 of the bending expansion thrust channels 13 of the three push mechanisms are evenly arranged around the rotation axis.

[0124] It increases overall thrust while maintaining the mechanical strength of individual thrust mechanisms at a low cost. It also features uniform thrust distribution.

[0125] The exhaust port 4 of the push mechanism is oriented obliquely inward towards the tangent of the rotation, forming a system that exhausts obliquely backward.

[0126] In this embodiment, the oblique rear exhaust has the following advantages: first, it can reduce the radius of the necessary exhaust space, making it easier to arrange equipment; second, it facilitates centralized exhaust (tail gas) discharge; and third, it adapts to the high-speed rotating exhaust tangential following, improving efficiency and power.

[0127] Furthermore, the rotating carrier 7 has a cavity with gas pressure-bearing capacity; The inner cavity 8 of the cavity is connected to a gas supply channel 18 for supplying pressurized gas; The gas supply channel 18 has a rotary gas connector for connecting to a gas source.

[0128] In this embodiment, the beneficial effect is that it achieves integration and has the advantages of simple structure, low cost, and reliable performance.

[0129] Reference Figures 9-12 It has a built-in burner pusher device and a rotating carrier 7 that is pushed; The rotating carrier 7 has a cavity with gas pressure-bearing capacity; The cavity is connected to the air intake channel 12; The cavity contains a burner 16; The burner 16 of the cavity is connected to a fuel supply passage 17 for supplying fuel; The supply port has a rotary joint 14 for connecting to a fuel source.

[0130] In this embodiment, pressure is generated through internal combustion, producing pressurized gas in the inner cavity 8.

[0131] Reference Figure 11 , Figure 12 As shown, the inner cavity 8 of the cavity is connected to a gas supply channel 18 for supplying pressurized gas; The fuel supply channel 17 and the gas supply channel 18 are coaxially nested. It is also equipped with an air booster device connected to the air supply channel 18, the air booster device having an impeller 15; The impeller 15 and the rotating carrier 7 have the same axis of rotation. The rotating carrier 7 drives the impeller 15 to rotate directly or through a speed-changing mechanism.

[0132] In this embodiment, when the rotating carrier 7 rotates, it drives the impeller 15 to rotate, thereby pressurizing the air and providing combustion air to the pressurized inner cavity 8. Compared with traditional rocket engines, a booster gas engine is no longer required.

[0133] The above design has a coincident axis of rotation, which has the advantages of stable rotation, simple layout and low cost.

[0134] Furthermore, the fuel source is a compressed gas fuel tank, including but not limited to compressed natural gas tanks and liquefied gas tanks; Before the rotating carrier 7 starts to rotate, compressed gas fuel is introduced and ignited in the inner cavity 8; Regardless of whether ignition is successful or not, the compressed gaseous fuel will generate a driving force to rotate the rotating carrier 7. When the rotating carrier 7 rotates to a sufficient speed, the air pressurization device can provide enough air to output power to the outside through the rotating carrier 7.

[0135] In this embodiment, the drag-start device for the gas turbine and the drag-start process are omitted.

[0136] Furthermore, in order to provide a concise description of exemplary embodiments, not all features of actual embodiments may be described, i.e., those features that are not relevant to the currently considered best mode for carrying out the invention, or those features that are not relevant to implementing the invention.
