Description

Technical Field

[0001] This invention relates to sea and air transport vehicles, and more specifically, to a track-driven device that can be installed on sea or air transport vehicles and change their tracks. Background Technology

[0002] Objects in motion, whether they are space shuttles, aircraft, rockets, or missiles flying in the air, or objects sailing on the surface or underwater, will encounter air or water resistance during flight or navigation, and need to change their direction or trajectory in a timely manner; this process is called "orbit change". Existing orbit change methods mainly rely on mechanical components installed on the spacecraft for mechanical drive to achieve orbit transfer.

[0003] Here are some examples of current technologies used to change the trajectory of flying objects: In aircraft, such as commercial aircraft, heading can be changed by deflecting airflow in the desired direction; this process is usually achieved by tilting the aircraft's wing surfaces (such as rudders and ailerons), thereby turning the wing's force vector, which was originally entirely upward, into a lateral component.

[0004] When an aircraft needs to descend or climb, its elevator must be activated to change the aircraft's pitch angle. The elevator can be located on the horizontal stabilizer.

[0005] A major drawback of these traditional methods for changing the course of flying objects is that all the power required for the trajectory-changing mechanism comes from the aircraft's main engine. Aircraft engines are designed to be lightweight, miniaturized, and powerful; however, if the main engine also needs to power the trajectory-changing operation, these requirements are difficult to meet satisfactorily. Similarly, surface and underwater vehicles encounter water resistance during navigation, and existing trajectory-changing mechanisms are also less than satisfactory in dealing with such situations.

[0006] Therefore, it is necessary to develop a device that can effectively and efficiently assist air or sea vehicles in performing orbital changes. Summary of the Invention

[0007] Certain variations of the present invention provide a track maneuvering device for use on air or sea vehicles, which can be installed on air or sea vehicles and perform track changes effectively and efficiently.

[0008] Some variations of the present invention provide a track maneuvering device installed at a specific location on an air or sea vehicle, which uses a nozzle assembly to spray high-pressure fluid to perform track changes on the air or sea vehicle.

[0009] Certain variations of the present invention provide a rail-driven maneuvering device for use in air or sea vehicles, comprising: A fluid supply device includes a control valve connected to a compressed fluid source and a fluid supply pipe connected to the control valve; A main body includes an outer shell and an inner shell installed within the outer shell, the inner shell being rotatable about the longitudinal direction of the main body, and a fluid supply pipe extending into the inner shell of the main body and remaining stationary relative to the outer shell. A drive head is connected to the inner shell of the main body, so that when the inner shell rotates relative to the outer shell, the drive head also rotates synchronously along the longitudinal direction of the main body. The drive head has a drive cavity inside; and A nozzle assembly includes a first nozzle and a second nozzle; the first and second nozzles are in fluid communication with a fluid supply pipe, are movably supported in a drive chamber, and are configured to rotate accordingly with the drive head. The first and second nozzles are configured to further rotate about the lateral direction of the body, thereby enabling the first and second nozzles to be selectively pointed in a predetermined direction, so that when compressed fluid is ejected through the first and second nozzles, the trajectory of an aircraft or marine vehicle equipped with a track maneuvering device can be altered.

[0024] As shown in the attached figure Figures 1 to 3 , Figures 4A to 4B , Figures 5A to 5B , Figures 6A to 6B , Figures 7A to 7C and Figure 8 This illustration shows a track-driven maneuvering device according to a preferred embodiment of the present invention. The track-driven maneuvering device is used to change the trajectory of an object, such as an air vehicle or a marine vehicle (hereinafter collectively referred to as "vehicle 200" unless otherwise stated). The track-driven maneuvering device may include a fluid supply device 10, a body 20, a drive head 30, and a nozzle assembly 40.

[0025] The fluid supply device 10 may include a control valve 11 connected to a high-pressure fluid source, and a fluid supply pipe 12 connected to the control valve 11. The compressed fluid may be a high-pressure fluid, such as compressed air or water.

[0026] The main body 20 may include an outer shell 21 and an inner shell 22, the inner shell 22 being mounted within the outer shell 21 and configured to rotate about the longitudinal direction of the main body 20. A fluid supply pipe 12 may extend within the inner shell 22 of the main body 20 and remain stationary relative to the outer shell 21.

[0027] The drive head 30 can be connected to the inner shell 22 of the main body 20, so that when the inner shell 22 rotates relative to the outer shell 21, the drive head 30 is also driven to rotate in a corresponding manner along the longitudinal direction of the main body 20. The drive head 30 may have a drive cavity 31 inside.

[0028] The nozzle assembly 40 may include a first nozzle 41 and a second nozzle 42, which are in fluid communication with the fluid supply pipe 12, are movably supported in the drive cavity 31, and are configured to rotate accordingly with the drive head 30. The first nozzle 41 and the second nozzle 42 may be configured to rotate further about the lateral direction of the body 20, thereby enabling the first nozzle 41 and the second nozzle 42 to be selectively pointed in a predetermined direction, so that when compressed fluid is ejected through the first nozzle 41 and the second nozzle 42, the track of the vehicle 200 equipped with the track maneuvering device can be changed by the configured track maneuvering device.

[0029] According to a preferred embodiment of the present invention, the track maneuvering device of the present invention can be installed on an object moving in a fluid, such as an aircraft or a marine vehicle (i.e., "vehicle 200"). The aircraft can be an airplane, and the marine vehicle can be a ship. The function of the track maneuvering device is to change the trajectory of the object during its operation. Trajectory change can refer to altering the object's trajectory, such as, but not limited to, turning, ascending, descending, accelerating, or decelerating. It is worth noting that the vehicle 200 can be equipped with one or more track maneuvering devices of the present invention to achieve effective trajectory change. These track maneuvering devices can be positioned at predetermined locations on the vehicle 200 and centrally controlled by a digital control system 100.

[0030] The fluid supply device 10 can be connected to a compressed fluid (high-pressure fluid) source for altering the trajectory of the vehicle 200. A control valve 11 can be connected to the high-pressure fluid source, allowing high-pressure fluid to enter the body 20 via the control valve 11. High-pressure fluid can also be generated within the vehicle 200 via a separate system. The high-pressure fluid can be delivered and flow through the fluid supply pipe 12, extending into the body 20.

[0031] The main body 20 can be connected to the fluid supply device 10 and may be provided with a receiving cavity 23. The longitudinal direction of the main body 20 is as follows: Figure 1 As shown. The main body 20 can be made of a robust, durable, high-temperature resistant, corrosion-resistant, and lightweight material, such as metal or composite material. The outer shell 21 of the main body 20 can be fixed and can be mounted on the vehicle 200, preferably at a position most conducive to initiating track changes. For example, multiple track maneuvering devices (connected via direct mounting or other fluid piping systems) can be provided at the bottom or sides of the vehicle 200 to achieve vertical lifting of the vehicle 200. According to a preferred embodiment of the invention, the outer shell 21 of the main body 20 can be configured to have a generally circular cross-sectional shape. Therefore, the main body 20 can have a generally cylindrical structure.

[0032] The inner shell 22 of the main body 20 can be installed in the receiving cavity 23 and has rotatable characteristics. Specifically, the inner shell 22 can be driven to rotate about the longitudinal direction of the main body 20. Therefore, the main body 20 may further include at least one drive motor 24, which is installed in the receiving cavity 23 and is used to drive the inner shell 22 to rotate relative to the outer shell 21. The inner shell 22 and the drive head 31 can selectively rotate within a 360-degree range about the longitudinal direction of the main body 20. The drive motor 24 can drive the inner shell 22 to rotate via a gear mechanism such as a gear plate 27. The gear plate can connect the inner shell 22 to the drive motor 24.

[0033] As shown in the figure Figure 1As shown, the inner shell 22 can also be configured as a cylindrical hollow structure, wherein the fluid supply pipe 12 can extend along the longitudinal direction of the main body 20 and pass through the inner shell 22. The high-pressure fluid supplied via the control valve 11 is expected to have extremely high temperatures, therefore the fluid supply pipe 12 can be made of a material capable of withstanding high temperatures and pressures, such as metal or composite materials.

[0034] The main body 20 may also include a braking device 25, which includes at least one brake disc 251 mounted within the receiving cavity 23 and engaging with the outer surface of the inner shell 22 to selectively decelerate it. The braking device 25 may be electrically connected to the digital control system 100 to control the rotation of the inner shell 22 relative to the outer shell 21.

[0035] Those skilled in the art will understand that by selectively driving the inner housing 22 to rotate or stop rotating, the drive head 30 can also be driven to rotate or stop rotating synchronously. The speed and duration of rotation can be controlled by the digital control system 100.

[0036] Because the high-pressure fluid flowing through the fluid supply pipe 12 has an extremely high temperature, the space between the fluid supply pipe 12 and the inner shell 22 of the main body 20 can be effectively insulated, thereby minimizing heat transfer to the inner shell 22 or other components of the track-mounted motor device of the present invention. Therefore, the main body 20 may further include a heat insulation device 26 disposed between the fluid supply pipe 12 and the inner shell 22 of the main body 20, designed to prevent heat transfer to surrounding components. The heat insulation device 26 may be configured as a heat insulation layer, a vacuum layer, or other heat insulation mechanism.

[0037] The drive head 30 can be positioned below the main body 20 and connected to the inner shell 22, allowing the drive head 30 to rotate synchronously with the rotation of the inner shell 22. (See figure.) Figure 1 As shown, the drive head 30 may have a hollow structure and a convex outer surface 33, resembling an inverted mushroom in appearance. The rotatable configuration of the inner shell 22 and the drive head 30 can be achieved through a flange 50, a bearing 60, and preferably a gear assembly.

[0038] The fluid supply pipe 12 can extend into the drive cavity 31 of the drive head 30. The first nozzle 41 and the second nozzle 42 can be connected to the fluid supply pipe 12 within the drive cavity 31, thereby enabling fluid communication between the fluid supply pipe 12 and the first nozzle 41 and the second nozzle 42. Thus, high-pressure fluid from the fluid supply device 10 can be guided to the first nozzle 41 and the second nozzle 42 through the fluid supply pipe 12. In other words, the fluid supply pipe 12, the first nozzle 41, and the second nozzle 42 can form a three-way channel structure.

[0039] The first nozzle 41 can be pivotally connected to the fluid supply pipe 12 in the drive cavity 31. The first nozzle 41 may have a first connecting portion 411 and a first spray portion 412 extending from the first connecting portion 411. According to a preferred embodiment of the invention, the first connecting portion 411 may extend in the transverse direction of the body 20, while the first spray portion 412 may extend in the longitudinal direction of the body 20, thereby forming a generally L-shaped structure for the first nozzle 41, as shown in the figures. Figure 1 As shown. The first nozzle 41 can be pivotally mounted within the drive cavity 31. Specifically, the first nozzle 41 can be mounted within the drive cavity 31, allowing it to pivot about the lateral direction of the main body 20. In this preferred embodiment, the pivotal range of the first nozzle 41 is approximately 180 degrees.

[0040] The first nozzle 41 may have a first injection channel 413 extending along the first connecting portion 411 and the first injection portion 412, serving as a channel for high-pressure fluid. Therefore, the first injection channel 413 may be connected to the fluid supply pipe 12.

[0041] Similarly, the second nozzle 42 can be pivotally connected to the fluid supply pipe 12 within the drive cavity 31. The second nozzle 42 may have a second connecting portion 421 and a second spray portion 422 extending from the second connecting portion 421. According to a preferred embodiment of the invention, the second connecting portion 421 may extend in the transverse direction of the body 20, while the second spray portion 422 may extend in the longitudinal direction of the body 20, thereby forming a generally L-shaped structure for the second nozzle 42, as shown in the figures. Figure 1 As shown. The second nozzle 42 can be pivotally mounted within the drive cavity 31. Specifically, the second nozzle 42 can be mounted within the drive cavity 31, allowing it to pivot about the lateral direction of the main body 20. In this preferred embodiment, the pivotal range of the second nozzle 42 is approximately 180 degrees.

[0042] The second nozzle 42 may have a second injection channel 423 extending along the second connection portion 421 and the second injection portion 422, serving as a channel for high-pressure fluid. The second injection channel 423 may also be connected to the fluid supply pipe 12.

[0043] Depending on the application, the nozzle assembly 40 may include only one nozzle. That is, the nozzle assembly 40 may include only a first nozzle 41 connected to the fluid supply pipe 12. The structure of the first nozzle 41 may be the same as the structure of the first nozzle 41 described above.

[0044] The nozzle assembly 40 may further include a first nozzle motor 43 and a second nozzle motor 44, which are mounted within the drive head 30 and used to drive the first nozzle 41 and the second nozzle 42 respectively, causing the first nozzle 41 and the second nozzle 42 to pivotally move in the aforementioned manner. The first nozzle motor 43 and the second nozzle motor 44 may be electrically connected to a digital control system 100, which can selectively control the operation of the first nozzle motor 43 and the second nozzle motor 44. Therefore, by controlling the operation of the first nozzle motor 43 and the second nozzle motor 44, the orientation of each first nozzle 41 and the second nozzle 42 can be selectively changed, thereby changing the injection angle of the high-pressure fluid.

[0045] From the above description, those skilled in the art will understand that by controlling the rotation of the drive head 30 and the pivoting of the first nozzle 41 and the second nozzle 42, the digital control system 100 can conveniently and accurately control the orientation of the first nozzle 41 and the second nozzle 42, thereby enabling the injection of high-pressure fluid to change the trajectory of the corresponding vehicle 200.

[0046] The following embodiments illustrate how the track-mobilizing device of the present invention causes a corresponding vehicle 200 to change its track. For example... Figure 4A and Figure 4B As shown, with multiple track-driven maneuvering devices installed at the bottom of the vehicle 200, the first nozzle 41 and the second nozzle 42 can be driven downwards, thereby spraying high-pressure fluid downwards relative to the vehicle 200. This design allows the vehicle 200, like an aircraft, to ascend or hover in the air.

[0047] As shown in the attached figure Figure 5A and Figure 5B As shown, when multiple track-driven mechanisms are installed on the bottom or side of the vehicle 200, the first nozzle 41 and the second nozzle can be driven to face rearward, thereby spraying high-pressure fluid rearward relative to the vehicle 200. This drives the vehicle 200 to move forward or travel. When the vehicle 200 needs to decelerate, the user can control the digital control system 100 to drive the first nozzle 41 and the second nozzle 42 to pivot in opposite directions, thereby generating resistance and causing the vehicle 200 to decelerate.

[0048] As shown in the attached figure Figure 6A and Figure 6B As shown, when multiple track maneuvers are installed at various locations on the vehicle 200, the first nozzle 41 and the second nozzle can be driven to face different directions, thereby causing the high-pressure fluid to be sprayed relative to the vehicle 200 in the corresponding directions. This enables the vehicle 200 to perform customized track changes.

[0049] As shown in the attached figure Figure 7A As shown, when multiple track-driven maneuvering devices are installed on both sides of the vehicle 200, such as the first nozzle 41 and the second nozzle 42 installed on both sides of the vehicle 200, they can be driven to point in different directions, thereby causing high-pressure fluid to be sprayed relative to the vehicle 200 in the corresponding direction. This enables the vehicle 200, such as an aircraft carrier, to perform customized turning maneuvers.

[0050] As shown in the attached figure Figure 7B As shown, when multiple track-driven devices are installed on both sides of the vehicle 200, the first nozzle 41 and the second nozzle 42 of the two track-driven devices located on both sides of the vehicle 200 can be driven to face upward and downward directions, respectively, thereby causing high-pressure fluid to be sprayed relative to the vehicle 200 in the corresponding directions. This enables the vehicle 200 to perform customized ascending or descending operations.

[0051] As shown in the attached figure Figure 7C As shown, when multiple track maneuvering devices are installed beneath an air or sea vehicle, the nozzles 41 (42) of all track maneuvering devices are driven to face the same direction, thereby causing high-pressure fluid to be ejected in the corresponding direction relative to the air or sea vehicle. This enables the air or sea vehicle to perform customized track-changing operations.

[0052] It is worth mentioning that, by controlling the rotation of the drive head 30, the tilt angle of the first nozzle 41 and the second nozzle 42, and the pressure of the high-pressure fluid, the orbital maneuvering device of the present invention can "manipulate" the navigation trajectory of the aircraft or marine vehicle it carries. The change of trajectory may include turning, ascending, descending, or other forms of alteration.

[0053] Therefore, this invention solves the problem faced by traditional flying objects such as aircraft or seagoing vessels, namely, that changing their trajectory requires high-power and complex mechanical components, such as different types of wings on an aircraft. The trajectory maneuvering device of this invention can achieve trajectory changes without utilizing the traditional mechanical components found on aircraft or seagoing vessels.

[0054] Furthermore, the high-pressure fluid utilized by the track-driven device of the present invention can be obtained through various mechanisms. For example, when the track-driven device is applied to a marine vehicle, the high-pressure fluid can be high-pressure fluid discharged from other components of the marine vehicle. This type of high-pressure fluid can be reheated to meet the pressure requirements of the track-driven device for changing the track of the marine vehicle. Alternatively, high-pressure water can also be supplied (through other means) to the fluid supply device 10, thereby providing high-pressure fluid to the nozzle assembly 40.

[0055] Each track-driven device in this invention can be mounted on an aircraft or sea vehicle, such that only its drive head 31 is exposed outside the aircraft or sea vehicle on which it is mounted. (See attached figures.) Figure 8 As shown, as an alternative, each complete track-mounted motor unit can also be installed at a certain distance from the vehicle 200 via a specially structured connecting pipe 70. The connecting pipe 70 can connect the track-mounted motor unit to a high-pressure fluid source located inside the vehicle 200.

[0056] Although the present invention has been illustrated and described in conjunction with preferred embodiments and several alternatives, it is not limited to the specific description contained herein. Other alternatives or equivalent components may also be used to implement the present invention.
