Description
Technical Field
[0001] This invention belongs to the field of aircraft launch technology, specifically relating to an aircraft rotary launch device and system. Background Technology
[0002] Fixed-wing aircraft and rotorcraft are designed to meet specific mission objectives, offering advantages such as high speed, long endurance, and large payload. However, these aircraft require reaching and maintaining a certain speed for takeoff and landing, typically necessitating specially constructed runways for acceleration to takeoff speed and deceleration from landing speed to a stop. Fixed-wing aircraft struggle to take off and land in uneven terrain, such as in the wild, forests, and urban areas, severely limiting their operational flexibility. To enable fixed-wing aircraft to take off smoothly in environments without runways, auxiliary equipment is usually required to provide initial velocity, thus enabling takeoff without a runway.
[0003] Existing assisted takeoff and landing (ALT) systems mostly employ linear guidance-assisted takeoff, utilizing energy storage devices or actuators to generate thrust / pull forces to provide the initial velocity required for takeoff for fixed-wing aircraft within the size range of the linear guidance device. However, there are constraints between the structural dimensions of such ALT systems, the maximum output force of the actuators, and the overload capacity of the fixed aircraft, resulting in these systems often being bulky and providing very limited initial velocity. Furthermore, these devices are often large, making deployment and retraction cumbersome and time-consuming, and inconvenient to install on a vehicle for catapult launch during motion.
[0004] Chinese patent CN101327846A discloses a small UAV rotating catapult, which includes a launcher base, a rotating rocker arm, and a torsion spring. The launcher base consists of a tripod, a support rod, a fixed disc, and a limiting block. The upper end of the torsion spring is fixedly connected to the rotating rocker arm, and the lower end of the torsion spring is fixedly connected to the fixed disc on the base. This solution can provide a large initial velocity for the aircraft with a relatively small size. However, this solution uses a torsion spring as an energy storage element, which limits the range of initial velocities it can provide to the aircraft. Furthermore, because this solution uses a fixed-direction clamping frame, a fixed-length arm, and an uncontrolled torque drive, it cannot effectively control the aircraft's linear velocity and attitude based on the current angular velocity during the main shaft rotation to reduce the load on the arm. Most importantly, when releasing aircraft such as fixed-wing aircraft, the different distances of the left and right wings relative to the rotation center will generate a large lift difference, thus threatening the aircraft's safety.
[0005] Chinese patent CN101294782A discloses a launching device, including: a power system, a transmission system, a rotator, and a launched object; the power system is connected to the rotator through the transmission system, enabling the rotator to rotate, and the launched object is placed on the rotator. While this patent solves the power problem, it cannot effectively control the aircraft's linear velocity and attitude based on the current angular velocity during the rotator's rotation, thus failing to reduce the load on the rotator from the aircraft. This solution also fails to address the problem of a large lift difference caused by the different distances of the left and right wings relative to the rotation center, which threatens the aircraft's takeoff safety during release. Furthermore, the proposed solution cannot provide the aircraft with a complex and flexible initial launch state based on current advanced aircraft trajectory planning and control methods. Summary of the Invention
[0006] One aspect of this disclosure provides a rotating launch device and system for an aircraft. This launch device adjusts the attitude of the aircraft in real time during rotational acceleration and launch through an attitude adjustment device, so that the aircraft is in a safer or more advantageous initial state at launch.

The launcher is mounted on the third link. The first, second, and third revolute joints are all driven by servo drives, energy storage devices, or a combination of servo and energy storage devices.
[0016] Furthermore, the attitude adjustment device can reciprocate radially along the rotation center of the rotating body.
[0017] Preferably, the rotating body is a rotating structure with at least one rotating arm, and the attitude adjustment device is disposed on the rotating arm.
[0018] Furthermore, the rotating arm is a single-stage or multi-stage telescopic mechanism, or a mechanical arm composed of two or more rotating joints, all of which are servo driven.
[0019] Furthermore, the rotating arm is provided with a connecting block, and the rotating arm is connected to the support body through the connecting block. The rotating arm and the connecting block are rotatably connected, and a rotation locking mechanism is provided at the connection point.
[0020] Preferably, in one embodiment, the rotating body is a rotary table, and the attitude adjustment device is disposed on the rotary table.
[0021] Furthermore, a linear guide rail is provided radially along the upper edge of the rotary table, and the attitude adjustment device is installed on the moving part of the linear guide rail.
[0022] The aforementioned driving device is the launched aircraft itself; or
[0023] The drive unit is an aerodynamic actuator mounted on a rotating body; or
[0024] The driving device is a driver located at the coupling point between the support and the rotating body. The driver is fixedly mounted on the support, and its power output end is connected to the rotating body; or
[0025] The driving device is a driver, which is mounted on the base. The support body and the rotating body are fixedly connected, and the support body and the base are rotatably connected. The power output end of the driver is connected to the support body and drives the support body to rotate, thereby driving the rotating body to rotate.
[0026] Furthermore, the rotating body can reciprocate along the length of the support.
[0027] Furthermore, an angle adjustment structure is provided between the support body and the base, and the angle adjustment structure is used to adjust the angle between the support body and the base.
[0028] Furthermore, the tilt adjustment structure comprises a rotating joint between the support body and the base, wherein the horizontal angle between the support body and the base is adjusted via the rotating joint, which is driven by a servo module support body tilt drive device; or

[0030] The base is equipped with a linear guide rail, and a connecting rod is provided between the moving part of the linear guide rail and the support body. The tilt angle between the support body and the base can be adjusted by adjusting the position of the moving part of the linear guide rail.
[0031] In addition, the rotating body is also provided with a balancing arm to reduce the torque on the base in the roll and pitch directions when the rotating body is stationary and during rotation. The balancing arm is provided with a counterweight block for counterweighting. The counterweight block can reciprocate radially along the rotation center of the balancing arm. Its distance from the rotation axis of the rotating body is adjustable in real time, and it can be quickly disengaged from the balancing arm.
[0032] A launch system for an aircraft includes the aforementioned rotating launch device and controller. The controller is a general-purpose computer or an embedded controller.

[0053] Please see Figure 1The rotating launch device of the present invention includes a cylindrical support body 1 and a rotating body 2 that rotates around the axis of the support body. In this embodiment, the rotating body is provided with two rotating arms 201 and a drive device 4 that provides power for the rotation of the rotating body 2. The rotating arms 201 are provided with an attitude adjustment device 5, which is used to adjust the attitude of the aircraft in real time during rotation acceleration and launch. The attitude adjustment device 5 is provided with a launch rack 6 that docks with the aircraft. The launch rack 6 and the attitude adjustment device 5 can be integrated or separate designs. The launch rack 6 uses mechanical or electromagnetic means to achieve the connection and disconnection between the aircraft and the attitude adjustment device 5. For example, a U-shaped manipulator gripping method is used to clamp the mating parts on the aircraft to achieve the docking of the launch rack 6 with the aircraft. The connection and disconnection of the aircraft are achieved through the cooperation between the launch rack 6 and the aircraft. The bottom of the support body 1 is provided with a base 3 to provide stable support for the entire launch device.
[0054] The present invention provides four embodiments of the driving device 4. The four embodiments are mainly used to illustrate the position of the driving device 4. In practical applications, different implementation methods can be selected according to different needs and existing technologies.
[0055] In the first embodiment of the drive device 4, the support body 1 is rotatably connected to the rotating body 2, and the drive device 4 that provides rotational driving force for the rotating body 2 is the launched aircraft itself, that is, the flight power of the aircraft itself provides power for the rotation of the rotating body 2.
[0056] In a second embodiment of the drive device 4, the drive device 4 is mounted on the rotating body 2, the support body 1 is rotatably connected to the rotating body 2, and the rotating body 2 is provided with a drive that relies on aerodynamics. The common drive is a motor-driven propeller drive, which provides power for the rotation of the rotating body 2.
[0057] In a third embodiment of the drive device 4, the drive device 4 is located at the coupling point between the support body 1 and the rotating body 2. For example, a motor is fixedly installed on the support body 1, and the power output end of the motor is connected to the rotating body 2. The motor can also be replaced with other suitable drivers.
[0058] In a fourth embodiment of the drive device 4, the drive device 4 is mounted on the base 3, the support body 1 is fixedly connected to the rotating body 2, the support body 1 is rotatably connected to the base 3, a motor is mounted on the base 3, the power output end of the motor is connected to the support body 1 and drives the support body 1 to rotate, thereby driving the rotating body 2 to rotate. The motor can also be a steam turbine or a fuel engine.
[0059] In one embodiment, the rotating body 2 is fixedly connected to the support body 1 along the length of the support body 1, that is, the rotating body 2 is relatively stationary along the length of the support body 1.
[0060] More preferably, in another embodiment, the rotating body 2 can reciprocate along the length of the support body 1, as in embodiment one, such as... Figure 2 As shown, the support body 1 is equipped with a guide rail, and a slider 101 is mounted on the guide rail. The rotating body 2 is placed on the slider 101, and the reciprocating motion of the rotating body 2 is achieved by the sliding of the slider 101; Implementation scheme two, as shown... Figure 3 As shown, the support body 1 is a single-stage or multi-stage telescopic mechanism, and the rotating body 2 is set on the top of the support body 1. The reciprocating motion of the rotating body 2 is realized by the extension and retraction of the telescopic mechanism. In the third embodiment, the support body 1 is a double-legged or multi-legged or main-legged and auxiliary support structure. The height and angle of the rotating body 2 are changed by changing the length or position of each leg or auxiliary support, thereby realizing the reciprocating motion of the rotating body 2. This embodiment can also better control the attitude of the aircraft.
[0061] In this invention, the attitude adjustment device 5 is used to adjust the attitude of the aircraft during its circular motion and when it detaches from the launch pad 6 for launch, making the aerodynamic forces acting on the aircraft more reasonable during these processes. Adjusting the aircraft's attitude helps to: firstly, reduce the aircraft's disturbance to the center of rotation during acceleration before takeoff; and secondly, ensure safer takeoff by providing a flexible initial flight state, allowing the aircraft to better adapt to the planned flight trajectory. The attitude adjustment device 5 is constructed using a multi-axis arbitrary combination method according to the type of aircraft to adjust the required pitch, roll, and yaw angles, controlling the aircraft to be in the optimal attitude. In particular, by combining environmental perception and planning control methods, the launch state can be planned very flexibly, adapting to very complex motion planning, thereby achieving launch capabilities that are impossible with existing technologies. The attitude adjustment device 5 is essentially a robotic arm composed of two or more revolute joints. By adjusting the angles of each axis on the robotic arm, the aircraft obtains the desired attitude. Two typical configurations are selected here for further explanation.
[0062] For a first embodiment of the attitude adjustment device 5 of the present invention, please refer to [link / reference]. Figure 4 It consists of three links connected in sequence by a rotating joint. The first link 501 is connected to the rotating body 2 through the first rotating joint. The axis of the first rotating joint is radially radiating from the center of the rotating body 2. The first link 501 is connected to the second link 502 through the second rotating joint. The axis of the second rotating joint is perpendicular to the axis of the first rotating joint. The second link 502 is connected to the third link 503 through the third rotating joint. The axis of the third rotating joint is perpendicular to the axis of the second rotating joint. The launcher 6 is mounted on the third link 503. The first, second, and third rotating joints are all driven by servo motors.
[0063] To optimize drive configuration, some key rotating joints can be driven by energy storage devices or a combination of servo drives and energy storage devices. For example, when the aircraft adopts a horizontal launch mode, the third rotating joint of the attitude adjuster can be driven by hydraulic, pneumatic, or spring energy storage devices to pre-store energy or temporarily store energy for the energy storage device during the acceleration of the rotating body 2 via servo drive. As the aircraft approaches launch, the energy stored in the energy storage device is released accordingly via the drive components based on the energy required to correct the aircraft's heading, ensuring that the aircraft's heading is at the expected value at launch.
[0064] When adjusting the aircraft's attitude, the first link 501 adjusts the pitch angle, the second link 502 adjusts the roll angle, and the third link 503 adjusts the yaw angle. Here, we will illustrate the application of this embodiment. For example, the plane of rotation of the rotating body 2 is parallel to the ground, and the angles of the first link 501 and the second link 502 of the attitude adjustment device 5 are initial angles, keeping the aircraft in a horizontal position. Here, the aircraft is an unmanned aerial vehicle (UAV). Before launch, the yaw angle is adjusted by rapidly adjusting the angle of the third link 503. The aircraft is launched simultaneously with the adjustment, ensuring that the left and right wings have the same ground velocity at the moment of ejection, thus avoiding flight safety issues caused by unbalanced lift between the left and right wings due to rotational motion. Furthermore, by adjusting the angle of the first link 501, the pitch angle can be adjusted, thereby adjusting the angle of attack, allowing the aircraft to obtain optimal lift that matches its linear velocity upon ejection.
[0065] For a second embodiment of the attitude adjustment device of the present invention, please refer to [link / reference]. Figure 5 It includes three links connected in sequence. The first link 504 is connected to the rotating body 2 through a first revolute joint. The axis of the first revolute joint is perpendicular to both the axis of the rotating body 2 and the radial direction of the center of the rotating body 2. The first link 504 is connected to the second link 505 through a second revolute joint. The axis of the second revolute joint is perpendicular to the axis of the first revolute joint. The second link 505 is connected to the third link 506 through a third revolute joint. The axis of the third revolute joint is perpendicular to both the axes of the first and second revolute joints. The launcher is mounted on the third link 506. The first, second, and third revolute joints are all driven by servo drives, energy storage devices, or a combination of servo drives and energy storage devices.
[0066] The attitude adjustment device 5 can reciprocate radially along the rotation center of the rotating body 2. In one embodiment, the rotating arm 201 uses a single-stage or multi-stage telescopic mechanism to control the distance between the attitude adjustment device 5 and its rotation center, the purpose of which is to fully utilize the capability of the drive device 4. For example, during the initial acceleration rotation phase of the rotating body 2, the length of the telescopic mechanism is adjusted in real time according to the drive constraints of the drive device 4 and the mission's requirements for the angular velocity of the rotating body, thereby fully utilizing the drive capability of the drive device 4. More specifically, since the distance between the aircraft and the rotation center is proportional to the torque of the drive device 4, the distance between the attitude adjustment device 5 and the rotation center is set to the shortest during the initial startup of the rotating launch device. During the acceleration rotation process, the attitude adjustment device 5 gradually adjusts the length of the rotating body according to the type of aircraft to meet the takeoff requirements of the aircraft, while reducing the performance requirements of the drive device 4. For another example, when the driving force of the third link 503, 506 of the attitude adjustment device 5 cannot meet the requirements of a small-radius, high-speed launch mode, a long-link, low-speed launch mode can be used.
[0067] In one embodiment, please refer to Figure 6 A rotating joint 301 is provided between the support body 1 and the base 3. Its function is to adjust the normal direction of the rotation plane of the rotating body 2, thereby adjusting the velocity direction when the aircraft is launched. This rotating joint 301 is driven by a servo module support body 1 tilt drive device; alternatively, a servo-driven worm gear can be used, with the worm gear output shaft connected to the rotating shaft between the support body 1 and the base 3; or a linear guide rail can be provided on the base 3, with a connecting rod between the moving part of the linear guide rail and the support body 1. The tilt angle of the support body 1 can be adjusted by adjusting the position of the moving part of the linear guide rail. Specifically, the angle between the support body 1 and the ground can be set to α. When the angle between the aircraft's rotational velocity vector and the ground is α, the aircraft disengages from the launch arm, thus obtaining an initial velocity direction obliquely upwards at an angle α with the ground. The aircraft launched obliquely upwards has more adjustment time to enter normal flight mode, making takeoff more flexible and safer. Furthermore, this embodiment facilitates the folding and storage of the device.
[0068] Please see Figure 7To further facilitate the storage of the launching device, the rotating body 2 also includes a connecting block 204. The rotating arm 201 is connected to the support body 1 via the connecting block 203. The rotating arm 201 and the connecting block 203 are rotatably connected, and a rotation locking mechanism is provided at the connection point. In one embodiment, the rotation locking mechanism can be a worm gear, with the worm gear output shaft connected to the rotating shaft between the rotating arm 201 and the connecting block 203. The locking purpose is achieved through the self-locking property of the worm gear. The worm can be driven by a handwheel or a servo drive. In another embodiment, the rotating joint here can be driven by a linkage slider mechanism. The linkage is connected to one of the rotating arms or the support body 1 via a rotating joint, and the slider is connected to the other via a sliding joint. In another real-time solution, a positioning pin or method such as applying pressure to increase static friction is used to lock the device at a preset or desired position.
[0069] In one embodiment, please refer to Figure 8 and Figure 9 The rotating body 2 is also equipped with a balancing arm 204 to reduce the roll and pitch torque on the base 3 when the rotating body is stationary and during rotation. The balancing arm 204 has a counterweight block 205 for counterweighting, the distance between which is adjusted in real time by a servo motor to meet real-time balance requirements. When necessary, the counterweight block 205 can be quickly disengaged from the balancing arm 204 to prevent sudden changes in the system's force balance when the aircraft is ejected. For example, the balancing arm 204 can employ a single-stage or multi-stage telescopic mechanism or a guide rail slider mechanism; here, a telescopic mechanism is used for explanation. The counterweight block 205 is located at the end of the telescopic mechanism, and its position is controlled by the telescopic mechanism. The telescopic mechanism and the counterweight block 205 are electromagnetically fastened together. When the aircraft is ejected, the counterweight block 205 quickly retracts to near the center point. When necessary, the electromagnetic connection between the telescopic mechanism and the counterweight block 205 can be released, allowing the counterweight block 205 to quickly disengage from the balancing arm 204.
[0070] Another embodiment of the present invention, in conjunction with the above embodiments, please refer to... Figure 10 In this embodiment, the rotating body 2 is a rotating platform 202. The rotating platform 202 can be of any shape. Preferably, the rotating platform 202 is circular. At least one attitude adjustment device 5 is provided on the rotating platform 202.
[0071] Please see Figure 11 The launch system of the present invention includes the aforementioned rotating launch device and controller 7. Controller 7 is a general-purpose computer or embedded controller. The rotating launch device and controller 7 are interconnected. Controller 7 obtains the status data of each node of the rotating launch device and the status data of the aircraft in real time. Based on the performance of the aircraft, it selects the appropriate program to control the working state of the launch device so that the aircraft can be launched in a relatively good attitude.
[0072] To better adapt to the environment, this system is equipped with an environmental sensing device 8, which includes at least one of the following: an anemometer, an airflow meter, a lidar sensor, and a visual sensor. The environmental sensing device 8 is connected to the controller 7. The environmental sensing device 8 and the controller 7 are used to sense surrounding environmental information and to control the various components of the rotating launcher in real time.
