Aircraft

Abstract

The invention discloses an aircraft which comprises a fuselage, wings, first motors, first propellers, second motors and second propellers, wherein the fuselage is provided with a symmetrical plane; the axis of the fuselage and the center of gravity of the aircraft are positioned on the symmetrical plane of the fuselage; each first motor is fixed on the fuselage through a permanent seat; the output shaft of each first motor is respectively connected with a first propeller; the axis of the output shaft of each first motor is perpendicular to the axis of the fuselage, and the axis of the output shaft of each first motor is also parallel to or superposed with the symmetrical plane of the fuselage; after each first motor drives each first propeller to rotate, a longitudinal lift force is generated to the aircraft; each second motor can be connected with the fuselage or wings; the output shaft of each second motor is connected with a second propeller; each second motor can rotate around the axis perpendicular to the symmetrical plane of the fuselage; each second motor drives each second propeller to rotate so as to generate a force to the aircraft; and the longitudinal lift force generated to the aircraft and the horizontal force generated to the aircraft can be mutually converted.

Description

technical field [0001] The invention relates to an aircraft. Background technique [0002] Common aircraft in the aviation field generally include fixed-wing aircraft and multi-rotor aircraft. [0003] The fixed-wing aircraft is propelled by the engine, which generates horizontal thrust parallel to the axis of the fuselage, so that the fixed-wing aircraft can fly at high speed in the air. But because the engine cannot produce the lift perpendicular to the axis of the fuselage, the fixed-wing aircraft can only obtain the lift through the relative motion between the fixed wing and the air, so as to overcome the gravity of the fixed-wing aircraft, the size of the lift and the distance between the fixed-wing aircraft and the air. There is a positive correlation between the relative speed of motion, the greater the relative motion speed, the greater the lift obtained by the fixed-wing aircraft. Yet there are two shortcomings in the fixed-wing aircraft of the prior art: the firs...
