Description

Technical Field

[0001] The invention belongs to the technical field of aircraft equipment, and in particular relates to a fast-moving telescopic aerial refueling receiving rod and a use method thereof. Background Art

[0002] Aerial refueling is a multiplier for improving the capabilities of aircraft platforms. As drone technology continues to develop and mature, the number of drones used to perform various tasks is also increasing, which has brought about an urgent need for aerial refueling of drones. Autonomous aerial refueling technology can effectively improve the carrying capacity and endurance of drone equipment, and is an important direction for future drone application research.

[0003] The existing aerial refueling methods can be mainly divided into two forms: hard-tube aerial refueling and hose aerial refueling. Since hose aerial refueling is safer, the autonomous aerial refueling of unmanned aerial vehicles generally adopts hose aerial refueling. However, hose aerial refueling is easily disturbed. During the refueling process, the hose drogue system is very likely to produce aerodynamic instability under airflow disturbance. At the same time, the head wave effect also affects the docking of the drogue and the probe. When the receiving aircraft approaches the drogue, the drogue will deviate from the equilibrium position and oscillate due to the disturbed airflow. Because the mass of the drogue is much smaller than that of the receiving aircraft, when the drogue is offset, the response of the receiving aircraft is slower than that of the drogue, showing the phenomenon that the slow-dynamic receiving aircraft tracks the fast-dynamic drogue, making it very difficult for the receiving aircraft to accurately insert the refueling probe into the drogue. In order to improve the efficiency of autonomous aerial refueling, the stabilization drogue control technology is usually used, that is, controllable rudders or spoilers are installed on the drogue to achieve stable flight of the drogue, and good results have been achieved.

[0004] As a refueling subsystem for aerial refueling, the refueling probe is also an important part of autonomous aerial refueling, and is responsible for docking with the drogue and delivering fuel. Currently, the commonly used refueling probe is usually fixedly installed on the receiving aircraft. Due to the lack of freedom of movement, the application of the refueling probe has great limitations. When there is a height difference and side offset between the drogue and the refueling pipe, it can only be eliminated by adjusting the position of the aircraft, making it difficult to achieve efficient refueling.

[0005] Currently, there is an urgent need to develop a fast-moving, telescopic aerial refueling receiving rod and a method for using the same. Summary of the invention

A method for using a fast-moving telescopic aerial refueling boom, which is used for the fast-moving telescopic aerial refueling boom according to claim 8, characterized in that: The use method includes an installation method, a recovery method and a release method; The installation method comprises the following steps: a fast-moving telescopic aerial refueling boom is fixedly installed inside the fuselage of an unmanned refueling aircraft, the nozzle of the refueling boom (1) is integrated with the nose of the aircraft, and each single camera of the multi-focal compound eye camera is embedded in the nose of the aircraft, with the viewing angle being the same as the forward direction of the refueling boom (1); The recovery method comprises the following steps: the motor (24) receives an action command for recovering the oil receiving rod (1), the motor (24) rotates, and drives the gear I (21) to rotate counterclockwise through the motor main shaft gear (26), and the winch disc I (19) and the winch disc II (20) rotate counterclockwise synchronously with the gear I (21); at the same time, the front steering gear I (33) and the front steering gear II (34) synchronously retract the two fork ears (10) to ensure that the recovery channel of the oil receiving rod (1) is unobstructed; the two steel cables (11) are synchronously rolled up and respectively wound around the corresponding winch disc I (19) through the directional pulley (18). 19) and the capstan disc II (20), the oil receiving rod (1) is restricted by the guide rail (12) and is retracted along the axis of the housing (7), and the main spring (13) is gradually compressed to generate a preload; the gear II (22) and the gear I (21) rotate counterclockwise synchronously, and the slider (23) slides along the gear II (22); when the rear end surface of the retaining ring (30) contacts the limit sensor (15), the motor (24) receives a stop motion instruction and stops rotating, the slider (23) is engaged with the teeth of the gear II (22), and the oil receiving rod (1) is retracted to its position, completing the recovery of the oil receiving rod (1); The release method comprises the following steps: the rear servo (32) receives an action command for recovering the oil receiving rod (1), drives the gear II (22) to rotate, the slider (23) leaves the teeth of the gear II (22), the main spring (13) is released, and the oil receiving rod (1) is pushed to pop out along the axis of the housing (7) under the restriction of the guide rail (12), until the clamping ring (30) presses the annular shock absorbing pad (8), triggering the limit switch (9); at the same time, the front servo I (33) and the front servo II (34) work synchronously, and the two fork ears (10) are synchronously popped out under the elastic force of the auxiliary spring (14), relatively inserted into the housing (7) and located behind the clamping ring (30), so as to prevent the oil receiving rod (1) from rebounding; the oil receiving rod (1) is extended into place, and the release of the oil receiving rod (1) is completed.
