Abstract

The invention provides a flapping aircraft autonomous takeoff control system and method. The system comprises a remote control trolley, a bracket, a strain measuring device, a vehicle speed measuringdevice, a vehicle control panel and an airborne control panel. According to the invention, the vehicle speed measuring device is used to precisely control the speed of the remote control trolley; thestrain measuring device is used to measure the stress state; the data are used to accurately acquire the state information before the takeoff of a flapping aircraft; the flapping aircraft gets rid ofthe dilemma of hand-held and involuntary takeoff of a traditional flapping aircraft, and realizes autonomous takeoff; a better initial flight state of the flapping aircraft is acquired; at a suitableflapping frequency, the combination of the trolley system and the aircraft system can reduce power and improve efficiency; and the auxiliary system provided by the invention has the advantages of compact structure, light weight, easy carrying and convenient installation, and is suitable for application in autonomous takeoff control of the flapping aircraft.

Description

technical field [0001] The invention belongs to the technical field of flapping-wing aircraft, and in particular relates to an autonomous take-off control system and method of the flapping-wing aircraft. Background technique [0002] In recent years, Flapping-wing aerial vehicles (Flapping-wing aerial vehicles), as a new type of bionic aircraft, are bionic robots manufactured by imitating the flight methods of insects and birds. It has low and significant advantages, and has broad application prospects in national defense, military and civilian fields. However, because the flapping wing aircraft cannot flap its wings and take off in situ like the birds in reality. Through the force analysis of the flapping-wing aircraft, the weight of the aircraft is 10mN greater than the maximum lift it can provide under static conditions, which means that it is difficult for the fuselage to take off directly from a static state on the ground to generate enough lift to achieve flight. Th...
