Novel flight and aircraft

Abstract

The invention relates to a novel flight and an aircraft, belonging to the field of aviation. A new fight method which fully utilizes high-speed airflows comprises the following steps: all the high-speed airflows which are artificially generated simultaneously flow through wings and the upper surface of an aircraft body below the wings and then flow to a rear area. Thus, the high-speed airflows pass through the wings and the upper surface of the aircraft body in a motion course to supply a lift force and a thrust force to an aircraft; and because the wings are all in the high-speed airflows, the aircraft can accurately control a flight attitude in any flight state, and the lift force of the aircraft can be independent of the motion state of the aircraft. Even if an airplane is motionless, the same lift force can be obtained. The aircraft maintains a small angle of attack and the combined force of the thrust force and lift force of the aircraft is perpendicular to the ground, thus the aircraft can perpendicularly take off, hover in the air or perpendicularly land. Furthermore, downwash airflows do not exist corresponding to the lower part of the aircraft; and the aircraft has the common advantages of the high-speed flight of a fixed wing airplane and the perpendicular take-off and landing of a helicopter, and eliminates the defects of the fixed wing airplane and the helicopter.

Description

Technical field: [0001] Aviation sector Background technique: [0002] Most of the existing aircraft in the atmosphere have wings, such as fixed wings and rotary wings. This is because general airfoils have a large lift-to-drag ratio, and relevant data have also reported aircrafts utilizing the Coanda effect, which do not have airfoils that produce lift. [0003] Among winged aircraft, fixed-wing aircraft generally fly fast and require a long runway. Most air accidents occur during take-off and landing. Although some fixed-wing aircraft achieve vertical take-off and landing through rotating air nozzles, but The control performance of the aircraft is poor, the appearance is not smooth, and the resistance is large. [0004] Rotorcraft can take off and land vertically, but the power is mainly to provide lift, and the forward movement is only the component force when the rotor is tilted. Moreover, the shape of the aircraft is less smooth, the resistance is greater, the flight...
