Abstract

The invention relates to flight principle technology of unmanned aerial vehicles. An in-series coaxial twin-propeller tailstock-type vertical taking-off and landing unmanned aerial vehicle includes: a front-pulling power system, a main body, a tube sleeve propeller back-pushing power system, a tail tube, a cross-shaped tailstock, and a support leg damping system. The main body internally includes a battery cabin, a mission payload cabin, and a flight control system cabin; when the aerial vehicle is taken-off, the vehicle is support by the support leg damping system. The front-pulling propeller and the back-pushing tube sleeve propeller rotate to generate taken-off power, and meanwhile, the reversal torsional moments due to the propellers are reduced. Flight control manipulates ailerons and a control surface of the cross-shaped tailstock so that the ailerons and the cross-shaped tailstock generate steerage due to slip flow brought by fold propellers, thereby correcting and controlling the attitude of the aerial vehicle and ensuring flight of the aerial vehicle. During vertical landing, the support leg damping system works. The unmanned aerial vehicle has simple and reliable flight principle, and compared with inclined disc coaxial twin-propeller structure, the unmanned aerial vehicle is simpler in control principle.

Description

technical field [0001] The invention relates to the flight principle technology of an unmanned aerial vehicle, in particular to a tandem coaxial double propeller tailstock type vertical take-off and landing unmanned aerial vehicle. Background technique [0002] In recent years, the domestic drone industry has developed by leaps and bounds, and it is widely used in power line inspection, emergency rescue and disaster relief, forest monitoring, communication relay and other fields. The fixed-wing vertical take-off and landing UAV takes into account the vertical take-off and landing, fixed-point operation of the rotorcraft and the fast response and long endurance of the fixed-wing, and is suitable for performing mountain tasks. Its main development direction is divided into tailstock type and tilt rotor type. The fixed-wing vertical take-off and landing technology developed earlier, but the technology is complicated and the progress is slow, but so far only the V-22 "Osprey" a...
