AIRCRAFT

An aircraft, comprising: a power unit, used for generating air flow and comprising one or more exhaust ends; a lift assembly, comprising a wing body and one or more jetting pipes (301, 302); the jetting pipes (301, 302) are disposed at an upper wing surface (101) of the wing body and connected to the exhaust end, and the jetting pipes (301, 302) blow air in a direction parallel to the upper wing surface (101) of the wing body or toward the wing body. The lifting force of the aircraft comes from active jet airflows, the lift assembly can generate a lift force for a long time by using the optimal air velocity and angle of attack; the aircraft is less affected by flight conditions and atmospheric turbulence, is safe, and has higher lifting force efficiency; the aircraft eliminates an aircraft wing cantilever structure, integrates wings and a fuselage, and has a simple structure, reduced weight, and improved strength; the aircraft is able to take off and land vertically and is not dependent on airports and runways; a horizontal projection of the aircraft is close in size with the fuselage, and thus the aircraft has good take-off and landing adaptability.
