Abstract

The invention discloses a combined type aircraft adopting rotors and a vector propulsion system. The combined type aircraft includes a lift body, the rotors and the propulsion system, the angle of thrust generated by the propulsion system is variable, vertical upward lift can be generated during take-off, and the thrust is generated during flat flight; during the vertical take-off stage of the aircraft, the lift is provided by the rotors and the vector propulsion system; during acceleration of the aircraft, the lift generated by the lift body of the aircraft gradually increases, and the lift generated by the rotors gradually decreases; and in the cruising state, the lift of the aircraft is mainly generated by the lift body, the thrust is generated by a propulsion unit, in this way, the cruising flight efficiency is high, and good flight stability and maneuverability are achieved. According to the combined type aircraft, the rotors and the propulsion unit are enabled to work cooperatively, by changing the thrust direction of the propulsion unit, the propulsion unit can work effectively during take-off, flat flight and landing, and thus the performance of the aircraft is optimized.

Description

technical field [0001] The invention belongs to an aircraft, in particular to an aircraft capable of short-distance or vertical take-off and landing combined with a rotor and a vector propulsion system. Background technique [0002] Multi-rotor aircraft can realize the vertical take-off and landing of the aircraft, but this type of aircraft needs rotors to continuously generate lift when flying, and requires a lot of energy consumption during flight, so its load and range are limited. If the lift force can be generated by the lift body of the aircraft during the level flight phase of the aircraft, the energy demand required for the flight of the aircraft will be much smaller. At the same time, the speed and load of the aircraft can also be increased. [0003] At present, some aircraft use the rotor to generate lift when taking off, and generate thrust through the propulsion unit when flying in level flight. This type of aircraft has two sets of power systems, which increas...
