DETAILED DESCRIPTION

[0041] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the preferred embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] It should be noted that in the description of the embodiments of the present application, terms such as "upper", "lower", "inside", and "outside" indicating orientation or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0043] In addition, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0044] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0045] Before takeoff, aircraft must accelerate and roll along a long runway until they reach sufficient takeoff speed. This is no exception on aircraft carriers. Due to the limited size and length of aircraft carriers, they cannot accommodate the short takeoff distances required for carrier-based aircraft. Therefore, various short takeoff methods have been designed, including ski-jump takeoffs, steam-powered takeoffs, and electromagnetically driven takeoffs, among other assisted takeoff methods.

[0046] The existing technology primarily uses steam-driven takeoff, where a steam boiler generates high-temperature, high-pressure steam, which is then stored in an accumulator. When the accelerated object is ready for takeoff, the steam is converted into kinetic energy, generating work to propel the object into flight. However, this assisted takeoff method suffers from low gas efficiency and the inability to recycle the gas.

[0047] In view of this, the present application provides an accelerated object takeoff assistance device and takeoff method, which provides the accelerated object with the kinetic energy required for accelerated movement by setting a power system, an acceleration system and a shuttle. The power system includes a phase change unit and a mixed flow pressure equalizing unit. The acceleration system includes a traction member, a driving chamber, a power source interface and a condensation reflux interface. The two ends of the shuttle are respectively connected to the traction member and the accelerated object. The phase change unit is used for the phase change conversion of carbon dioxide. The mixed flow pressure equalizing unit is connected to the driving chamber through the power source interface so that the carbon dioxide after phase change is transported to the driving chamber, thereby improving the energy conversion efficiency and utilization efficiency. The carbon dioxide after phase change in the driving chamber drives the traction member to move the shuttle, so that the shuttle drives the accelerated object to accelerate. A buffer system is set to consume the residual kinetic energy of the driving chamber driving the traction member and the shuttle after the accelerated movement of the accelerated object is completed. A reset system is set on the hydraulic pipeline of the buffer system to drive the acceleration system and the buffer system to reset. By setting up a condensation reflux system, one end of the condensation reflux system is connected to the phase change unit, and the other end is connected to the driving cavity through the condensation reflux interface, thereby realizing the recycling of the phase-changed carbon dioxide in the driving cavity.

[0048] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] See also Figures 1 to 6, the present application provides an accelerated object takeoff auxiliary device, which is used to be set under the takeoff runway 200 of the accelerated object 100, and the accelerated object takeoff auxiliary device includes a shuttle 300, a power system 400, an acceleration system 500, a buffer system 600, a condensation reflux system 700 and a reset system 800, the acceleration system 500 includes a traction member 510, a drive cavity 520, a power source interface 530 and a condensation reflux interface 540, one end of the shuttle 300 is fixed to the traction member 510, and the other end is used for detachable connection with the accelerated object 100; the power system 400 includes a phase change unit 410 and a mixed flow equalizing unit 420 connected to the phase change unit 410, the phase change unit 410 is used for phase change conversion of carbon dioxide, and the end of the mixed flow equalizing unit 420 away from the phase change unit 410 is connected to the drive cavity 520 through the power source interface 530. The dynamic chamber 520 is connected so that the carbon dioxide after phase change is transported to the driving chamber 520. The carbon dioxide after phase change in the driving chamber 520 drives the traction member 510 to drive the shuttle 300 to move, so that the shuttle 300 drives the accelerated object 100 to accelerate and move; the buffer system 600 includes a buffer chamber 610 and a hydraulic pipeline 620 connected to the buffer chamber 610. The buffer system 600 is used to offset the carbon dioxide after phase change in the driving chamber 520 and consume the remaining kinetic energy of the accelerated object 100 after the accelerated movement ends. The reset system 800 is set on the hydraulic pipeline 620. The reset system 800 is used to drive the acceleration system 500 and the buffer system 600 to reset; the condensation reflux system 700 is connected to the phase change unit 410, and is connected to the driving chamber 520 through the condensation reflux interface 540 to recover the carbon dioxide after phase change in the driving chamber 520.

[0051] In the present application, one end of the shuttle 300 is fixedly connected to the traction member 510, and the other end is used for detachable connection with the accelerated object 100. That is, the accelerated object 100 is accelerated and moved under the drive of the shuttle 300. When accelerated to the take-off speed, the accelerated object 100 is detached from the shuttle 300 and takes off.

[0052] Among them, the phase change unit 410 is used for the phase change conversion of carbon dioxide. After the phase change, the carbon dioxide is mixed and pressure-balanced by the mixed flow pressure-balanced unit 420 and then enters the drive chamber 520 through the power source interface 530. It can be understood that carbon dioxide absorbs and releases a large amount of heat during the phase change process, which can achieve efficient energy conversion and utilization. However, traditional steam drive will have energy loss during transmission and use, and the energy utilization efficiency is low. At the same time, by performing phase change conversion on carbon dioxide through the phase change unit 410, compared with the traditional steam drive, the present application avoids the cylinder seam and improves reliability. Furthermore, the gaseous carbon dioxide entering the drive chamber 520 drives the traction member 510 to drive the shuttle 300 to move, so that the shuttle 300 drives the accelerated object 100 to accelerate on the take-off runway 200.

[0053] In a specific implementation, when the shuttle 300 drives the accelerated object 100 to accelerate and move to the moment when the accelerated object 100 takes off, the buffer system 600 is activated to offset the carbon dioxide after the phase change in the driving chamber 520, consume the remaining kinetic energy of the accelerated object 100 after the acceleration movement ends, and realize flexible buffering of the acceleration system 500.

[0054] Furthermore, a reset system 800 is provided on the hydraulic pipeline 620. When the buffer system 600 completes consumption of the remaining kinetic energy after the accelerated object 100 is accelerated, the reset system 800 is started to drive the acceleration system 500 and the buffer system 600 to reset for the next use.

[0055] Among them, when the reset system 800 resets the acceleration system 500 and the buffer system 600, the condensation reflux interface 540 is opened to start the condensation reflux system 700. The condensation reflux system 700 recovers the gaseous carbon dioxide in the driving chamber 520 through the condensation reflux interface 540. The gaseous carbon dioxide is converted into liquid carbon dioxide through the condensation reflux system 700. When the accelerated object 100 is driven to accelerate again, the liquid carbon dioxide in the condensation reflux system 700 enters the phase change unit 410 for phase change conversion, thereby realizing the recovery and reuse of carbon dioxide.

[0056] See also Figure 1 and Figure 4 In an embodiment of the present application, the condensation reflux system 700 includes a filter 710, a compressor 720, a dryer 730, a condenser 740 and a storage tank 750 connected in sequence. The recovered carbon dioxide passes through the filter 710, the compressor 720, the dryer 730, the condenser 740 in sequence to undergo phase change, and then enters the storage tank 750.

[0057] In some embodiments, after the phase-changed carbon dioxide in the drive chamber 520 enters the condensation reflux system 700 through the condensation reflux interface 540, it needs to pass through the filter 710, compressor 720, dryer 730, and condenser 740 in sequence to change phase into liquid carbon dioxide, and then enter the storage tank 750. The storage tank 750 is connected to the phase change unit 410. When the accelerated object 100 needs to be driven to move at an accelerated speed next time, the liquid carbon dioxide in the storage tank 750 enters the phase change unit 410 to be converted into gaseous carbon dioxide, passes through the mixed flow pressure equalizing unit 420 and the power source interface 530, and enters the drive chamber 520, driving the traction member 510 again to drive the shuttle 300 to move, so that the shuttle 300 drives the accelerated object 100 to move at an accelerated speed. This design realizes the reuse of carbon dioxide, solving the problem that the gas cannot be recycled in the current assisted takeoff method.

[0058] Specifically, filter 710 is provided at the front end of condensation reflux system 700. The recovered carbon dioxide first passes through filter 710 to remove impurities and particulate matter from the recovered carbon dioxide, ensuring smooth subsequent processing. The carbon dioxide is then pressurized by compressor 720, where the pressure can be between 2.5 MPa and 3 MPa.

[0059] It is understood that the pressurized carbon dioxide is dehumidified and dried in the dryer 730 to remove saturated water vapor in the carbon dioxide, ensuring that the carbon dioxide is not affected by moisture during the condensation process. The dried carbon dioxide is more conducive to condensation and improves condensation efficiency.

[0060] The dried carbon dioxide is then condensed in a condenser 740 to convert it from a gaseous state to a liquid state, facilitating storage while improving energy efficiency. The condensed and liquefied carbon dioxide is then stored in a storage tank 750 for reuse.

[0061] See also Figure 1 and Figure 5 In an embodiment of the present application, the phase change unit 410 includes a gas collecting pipe 411, at least one fixed plate 412, multiple phase change tubes 413 and multiple pressure relief valves 414, and the multiple phase change tubes 413 are fixed by the fixed plate 412; the phase change tubes 413 and the pressure relief valves 414 are arranged in a one-to-one correspondence, and the phase change tubes 413 are connected to the gas collecting pipe 411 through the pressure relief valve 414, and the gas collecting pipe 411 is connected to the mixed flow pressure equalizing unit 420, and the gas collecting pipe 411 is used to collect the high-pressure gas formed by the pressure relief valve 414 into the mixed flow pressure equalizing unit 420.

[0062] In specific implementation, multiple phase change tubes 413 are firmly fixed together by a fixing plate 412, thereby enhancing the structural stability of the phase change unit 410. Each phase change tube 413 is equipped with a pressure relief valve 414, which is connected to the gas collecting pipe 411 through the pressure relief valve 414, so as to facilitate disassembly, replacement and maintenance.

[0063] During use, when the pressure in each phase change tube 413 exceeds the rated pressure set by the pressure relief valve 414, the pressure relief valve 414 will be pushed open, and the supercritical carbon dioxide formed in the phase change tube 413 will be instantly depressurized and expanded into high-pressure gas, and then flow into the mixed flow pressure equalizing unit 420 through the gas collecting pipe 411. The mixed flow pressure equalizing unit 420 is provided with a pressure sensor, and the mixed flow pressure equalizing unit 420 adjusts the mixed flow pressure of the carbon dioxide gas. Thus, the mixed flow pressure equalizing unit 420 is used to stably output the carbon dioxide gas into the driving chamber 520.

[0064] See also Figure 1 、 Figure 5 and Figure 6In the embodiment of the present application, the phase change tube 413 includes a tube body 4131, a filling head 4132, a rear end cover 4133, a resistor core 4134 and an excitation tube 4135 connected to the resistor core 4134. The filling head 4132 and the rear end cover 4133 are respectively installed at both ends of the tube body 4131, and the rear end cover 4133 is used to connect with the pressure relief valve 414; the resistor core 4134 and the excitation tube 4135 are both located in the tube body 4131, and the end of the resistor core 4134 away from the excitation tube 4135 is fixed to the filling head 4132.

[0065] In this application, a filling head 4132 is mounted on one end of the tube body 4131. This head is equipped with a filling valve, allowing liquid carbon dioxide to enter the tube body 4131 through the filling head 4132. A rear end cap 4133 is mounted on the other end of the tube body 4131. This rear end cap 4133 is equipped with an interface for connecting to the pressure relief valve 414. The tube body 4131 is made of a high-strength alloy material and serves as a place for carbon dioxide phase conversion to occur.

[0066] It is understood that a resistor core 4134 and an excitation tube 4135 connected to the resistor core 4134 are disposed within the tube body 4131, and the end of the resistor core 4134 away from the excitation tube 4135 is fixedly connected to the filling head 4132. Thus, upon activating the phase change unit 410, the resistor core 4134, connected to the intelligent initiator, transmits an excitation current to the excitation tube 4135. The excitation tube 4135 releases a large amount of heat, causing the liquid carbon dioxide within the tube body 4131 to undergo a phase transition to a supercritical state. This increases the pressure within the tube body 4131. When the pressure within the tube body 4131 exceeds the rated pressure set by the pressure relief valve 414, the pressure relief valve 414 is pushed open, and the supercritical carbon dioxide is decompressed and expanded into high-pressure gas, which is then transported through the gas collecting pipe 411 to the mixed flow pressure equalization unit 420. The intelligent initiator can control the pressure output intensity of the phase change unit 410.

[0067] See also Figure 1 In an embodiment of the present application, the acceleration system 500 further includes a driving link 550, a first pulley set 560 and a plurality of fixed pulleys 570, and the fixed pulleys 570 are arranged at intervals to drive the traction member 510 to slide; part of the driving link 550 is located in the driving cavity 520, and the first pulley set 560 is fixedly connected to the end of the driving link 550 away from the driving cavity 520.

[0068] In a specific implementation, part of the driving connecting rod 550 is located in the driving chamber 520. When it is necessary to drive the accelerated object 100 to accelerate and move, the carbon dioxide that has undergone phase change in the phase change unit 410 is mixed and pressure-equalized by the mixed flow and pressure-equalizing unit 420, and then enters the driving chamber 520 through the power source interface 530. As a result, the gaseous carbon dioxide drives the driving connecting rod 550 to move relative to the driving chamber 520.

[0069] It can be understood that the first pulley group 560 is provided with multiple movable pulleys and fixed pulleys. When the driving connecting rod 550 moves relative to the driving cavity 520, the first pulley group 560 moves and rotates to drive the traction member 510 to slide with each fixed pulley 570, so that the traction member 510 drives the shuttle 300 to move, so that the shuttle 300 drives the accelerated object 100 to move at an accelerated speed.

[0070] See also Figure 1 In the embodiment of the present application, the buffer system 600 includes a buffer link 630 and a second pulley set 640, part of the buffer link 630 is located in the buffer cavity 610, and the second pulley set 640 is fixed to the end of the buffer link 630 away from the buffer cavity 610; the traction member 510 is wound around the first pulley set 560, the second pulley set 640 and each fixed pulley 570, and the buffer link 630 and the driving link 550 move simultaneously so that the first pulley set 560 and the second pulley set 640 drive the traction member 510 to slide relative to the first pulley set 560, the second pulley set 640 and each fixed pulley 570.

[0071] The second pulley set 640 is provided with multiple movable pulleys and fixed pulleys. The traction member 510 is wound around the first pulley set 560, the second pulley set 640, and each fixed pulley 570. The traction member 510 is wound around the first pulley set 560 and the second pulley set 640 a consistent number of times to ensure uniform force on both sides of the shuttle 300. When the acceleration system 500 drives the accelerated object 100 to accelerate, the buffer link 630 and the drive link 550 move simultaneously and in the same direction, causing the first pulley set 560 and the second pulley set 640 to drive the traction member 510 to slide. In turn, the traction member 510 drives the shuttle 300 to move, and the shuttle 300 drives the accelerated object 100 to accelerate.

[0072] In this application, the buffer system 600 is used to offset the phase-changed carbon dioxide within the drive chamber 520, consume the remaining kinetic energy of the accelerated object 100 after completion of its accelerated movement, and achieve flexible buffering of the acceleration system 500. Specifically, a portion of the buffer link 630 is located within the buffer chamber 610. When the shuttle 300 accelerates the accelerated object 100 until the object 100 detaches from the shuttle 300 and takes off, the buffer system 600 is activated. The pressure generated within the buffer chamber 610 drives the buffer link 630 to move in the opposite direction to the direction in which the drive link 550 drives the shuttle 300 to accelerate the accelerated object 100. This consumes the remaining kinetic energy of the accelerated object 100 after completion of its accelerated movement, achieving deceleration and buffering of the shuttle 300.

[0073] See also Figure 1 and Figure 3In an embodiment of the present application, the buffer system 600 also includes a state switching valve 650, a buffer back pressure valve 660, an electric proportional overflow valve 670 and an oil storage tank 680, and the oil storage tank 680 is connected to the hydraulic pipeline 620; the state switching valve 650, the buffer back pressure valve 660 and the electric proportional overflow valve 670 are all arranged on the hydraulic pipeline 620, and the state switching valve 650 is located between the buffer back pressure valve 660 and the electric proportional overflow valve 670, and the opening and closing of the state switching valve 650 controls the start and stop of the buffer system 600.

[0074] In some embodiments, when the accelerated object 100 accelerates and moves to the moment of separation from the shuttle 300 and takeoff, the sensor located on the takeoff runway 200 is triggered, and the sensor feeds back an electrical signal to the state switching valve 650, and the state switching valve 650 switches to the buffer position, that is, the control buffer system 600 is started, and pressure is formed in the buffer chamber 610. The buffer back pressure valve 660 and the electric proportional relief valve 670 work together to control the pressure in the buffer chamber 610 to transition smoothly, offsetting the residual kinetic energy of the accelerated object 100 after the accelerated movement ends, and realizing deceleration buffering of the shuttle 300.

[0075] Specifically, the buffer back pressure valve 660 is used to maintain the output pressure stable, making the deceleration process of the shuttle 300 smoother. The electric proportional relief valve 670 is used to ensure that the pressure in the buffer system 600 does not exceed the limit, playing the role of unloading and safety protection.

[0076] See also Figure 1 and Figure 2 In an embodiment of the present application, it also includes at least one cylinder body 900 and a piston 910 located in the cylinder body 900. The cylinder body 900 is fixed under the take-off runway 200 through a bracket 920. The cylinder body 900 is used to form at least one of the drive chamber 520 and the buffer chamber 610; the piston 910 is connected to at least one of the drive connecting rod 550 and the buffer connecting rod 630. The piston 910 moves relative to the cylinder body 900 to drive the drive connecting rod 550 and the buffer connecting rod 630 to move relative to the cylinder body 900.

[0077] For example, the cylinder body 900 is fixed below the takeoff runway 200 by a bracket 920, thereby improving the structural stability of the cylinder body 900. By using the first pulley set 560 and the second pulley set 640, the speed can be increased while the length of the cylinder body 900 can be shortened.

[0078] For specific implementation, see Figure 1The number of cylinder bodies 900 can be set to one, whereby the piston 910 slidingly arranged in the cylinder body 900 forms a driving chamber 520 and a buffer chamber 610 with the cylinder body 900 on both sides respectively, and the two ends of the piston 910 are respectively connected to the driving connecting rod 550 and the buffer connecting rod 630. When the piston 910 slides relative to the cylinder body 900, the volume of the driving chamber 520 and the buffer chamber 610 changes continuously, and the driving connecting rod 550 and the buffer connecting rod 630 move relative to the cylinder body 900 under the drive of the piston 910.

[0079] Alternatively, see Figure 2 The number of cylinder bodies 900 can be set to two, and the two cylinder bodies 900 respectively form a driving chamber 520 and a buffer chamber 610. The two pistons 910 are respectively connected to the driving connecting rod 550 and the buffer connecting rod 630. The ends of the driving connecting rod 550 and the buffer connecting rod 630 that are not connected to the piston 910 can be connected through a connecting block. Thus, when the piston 910 slides relative to the cylinder body 900, the driving connecting rod 550 and the buffer connecting rod 630 move synchronously relative to the cylinder body 900 driven by the piston 910.

[0080] It is understandable that the number and layout of the cylinder bodies 900 are given for illustrative purposes only and can be specifically configured according to actual needs, and this embodiment does not limit this.

[0081] See also Figure 1 and Figure 3 In the embodiment of the present application, the reset system 800 includes a reset control valve 810, a reset accumulator 820, a one-way valve 830, and a reset pump station 840 arranged in sequence. The opening and closing of the reset control valve 810 controls the start and stop of the reset system 800. The reset pump station 840 is electrically connected to a motor 850, and the motor 850 is used to drive the reset pump station 840 to supply energy to the reset accumulator 820; a safety valve 860 is provided at the output end of the reset pump station 840 to detect the output pressure of the reset pump station 840.

[0082] In some embodiments, the buffer system 600 offsets the phase-changed carbon dioxide in the driving chamber 520 and consumes the remaining kinetic energy of the accelerated object 100 after the accelerated movement ends. Then, the reset control valve 810 opens and the reset system 800 starts to operate.

[0083] It will be understood that reset accumulator 820 is used to maintain a stable pressure within hydraulic line 620 during the reset process. During operation, when the energy in reset accumulator 820 is insufficient to reset acceleration system 500 and buffer system 600, motor 850 will drive reset pump station 840 to pump hydraulic oil from oil tank 680 to provide reset accumulator 820 with the energy required to reset acceleration system 500 and buffer system 600. Check valve 830 ensures unidirectional flow of hydraulic oil, preventing it from flowing into reset pump station 840. Safety valve 860 controls the pressure supplied by reset pump station 840 to reset acceleration system 500 and buffer system 600, ensuring that the pressure does not exceed the limit, thereby enhancing operational safety.

[0084] See also Figure 7 Based on the above embodiment, the present application further provides a take-off method, which uses the above accelerated object take-off auxiliary device. The take-off method includes the following steps:

[0085] S101: The accelerated object takeoff assisting device is in a reset state, the condensation reflux interface 540 and the buffer system 600 of the accelerated object takeoff assisting device are both in a closed state, and the accelerated object 100 is connected to the shuttle 300 of the accelerated object takeoff assisting device.

[0086] It is understandable that before the accelerated object takeoff assisting device drives the accelerated object 100 to accelerate and move, the accelerated object takeoff assisting device is in a reset state, the condensate reflux interface 540 and the buffer system 600 are both in a closed state, and the hydraulic oil in the buffer chamber 610 can flow into the oil tank unimpeded.

[0087] S102: Open the power source interface 530 of the accelerated object takeoff assisting device, and the power system 400 of the accelerated object takeoff assisting device undergoes a phase change. The carbon dioxide after the phase change enters the acceleration system 500 of the accelerated object takeoff assisting device through the mixed flow pressure equalization unit 420 of the accelerated object takeoff assisting device, so that the acceleration system 500 drives the shuttle 300 to move, and the shuttle 300 drives the accelerated object 100 to accelerate and move until the accelerated object takes off.

[0088] After everything is ready, the operator issues a takeoff command, the power source interface 530 is opened, and the liquid carbon dioxide in the phase change unit 410 of the power system 400 undergoes an orderly phase change. The carbon dioxide after the phase change is mixed and pressure-equalized by the mixed flow and pressure-equalizing unit 420 and then enters the driving chamber 520 of the acceleration system 500. The carbon dioxide after the phase change drives the driving connecting rod 550 to move. The driving connecting rod 550 drives the traction member 510 to slide through the fixed pulleys 570, the first pulley group 560 and the second pulley group 640, thereby driving the shuttle 300 to move. In this way, the shuttle 300 drives the accelerated object 100 to accelerate and move until the accelerated object takes off.

[0089] S103 , when the shuttle 300 separates from the accelerated object 100 , the buffer system 600 of the accelerated object takeoff auxiliary device is activated to perform buffer braking.

[0090] Specifically, when the accelerated object 100 accelerates and moves to the moment of separation from the shuttle 300 and takeoff, the sensor located on the takeoff runway 200 is triggered, and the sensor feeds back an electrical signal to the state switching valve 650, which switches the state switching valve 650 to the buffer position, that is, controls the buffer system 600 to start. The buffer system 600 absorbs the remaining kinetic energy of the accelerated object 100 after the accelerated movement ends, so as to decelerate and buffer the piston 910 and the shuttle 300.

[0091] S104 , starting the reset system 800 of the accelerated object takeoff auxiliary device to reset the acceleration system 500 and the buffer system 600 , opening the condensation reflux interface 540 , and recovering the phase-changed carbon dioxide through the condensation reflux system 700 of the accelerated object takeoff auxiliary device.

[0092] Among them, after the buffering is completed, the reset control valve 810 is opened, the reset accumulator 820 and the reset pump station 840 start to operate, the driving acceleration system 500 and the buffer system 600 are reset, the condensation reflux interface 540 is opened, and the condensation reflux system 700 starts to operate to recover the carbon dioxide after phase change in the driving chamber 520 to convert the carbon dioxide from gaseous state to liquid state, thereby realizing the reuse of carbon dioxide.

[0093] In summary, the accelerated object takeoff assist device and takeoff method provided by the present application provide the kinetic energy required for accelerated movement to the accelerated object 100 by setting a power system 400, an acceleration system 500 and a shuttle 300. The power system 400 includes a phase change unit 410 and a mixed flow pressure equalizing unit 420. The acceleration system 500 includes a traction member 510, a drive chamber 520, a power source interface 530 and a condensation reflux interface 540. The two ends of the shuttle 300 are respectively connected to the traction member 510 and the accelerated object 100. The phase change unit 410 is used for the phase change conversion of carbon dioxide. The mixed flow pressure equalizing unit 420 is connected to the drive chamber 520 through the power source interface 530 so that the carbon dioxide after phase change is transported to the drive chamber 520, thereby improving energy conversion efficiency and utilization efficiency. The carbon dioxide after phase change in the drive chamber 520 drives the traction member 510 to drive the shuttle 300 to move, so that the shuttle 300 drives the accelerated object 100 to accelerate. A buffer system 600 is provided to dissipate the residual kinetic energy of the driving chamber 520, which drives the traction member 510 and the shuttle 300, after the accelerated object 100 has completed its accelerated movement. A reset system 800 is provided on the hydraulic line 620 of the buffer system 600 to reset the acceleration system 500 and the buffer system 600. A condensation reflux system 700 is provided, with one end of the condensation reflux system 700 connected to the phase change unit 410 and the other end connected to the driving chamber 520 via the condensation reflux interface 540, thereby enabling the recycling of the carbon dioxide that has undergone phase change within the driving chamber 520.
