Description

Technical Field

[0001] The utility model relates to the technical field of target drones, in particular to a target drone towing and releasing mechanism. Background Art

[0002] A target drone is a military aircraft used as a target for shooting training. This aircraft uses remote control or pre-set flight paths and modes to simulate enemy aircraft or incoming missiles during military exercises or weapon tests, providing imaginary targets and shooting opportunities for various types of artillery or missile systems. It is a type of unmanned aircraft. There are specially manufactured target drones, as well as those modified from old aircraft; there are single-use and multiple-use target drones.

[0003] The target towing system is used to simulate the characteristics of aircraft for military training, shooting, flight calibration, or to test the performance of weapon systems. With the application of many new technologies, the target towing system has a more comprehensive threat simulation function and a more accurate miss distance measurement method. The target towing system has evolved from the original targets such as flag targets and bag targets used only for anti-aircraft gun and aircraft gun shooting training to a modern target towing system.

[0004] During use, existing target drone towed targets are often towed directly by the target drone, where the towed target is carried directly on the ground for takeoff, or is released directly in the air. Although the towed target and the target drone are connected by a wire rope, the wind resistance of the towed target in the atmosphere can easily cause a certain impact on the target drone. There is a lack of a certain buffer structure to maintain the stability of the target drone itself during the towed target release process, which is not conducive to maintaining the safety of the target drone itself.
