Transversely staggered four-rotor aircraft

Abstract

The invention discloses a transversely staggered four-rotor aircraft mainly comprising a fuselage, supporting arms, a motor, rotors and a landing gear. Each two supporting arms among four supporting arms are distributed on both sides of the fuselage; the two supporting arms on the same side are installed up and down in a staggered manner; one end of each supporting arm is connected with the fuselage through a hinge mechanism, and a supporting seat is installed on the other end of the supporting arm; a motor is fixedly installed above the supporting seat; the rotors are installed on the rotating shaft of the motor; the landing gear is further installed below the supporting seat. When the aircraft works, the supporting arms and the landing gear are unfolded, and the positions of the supporting arms are kept by locking mechanisms, so that normal flight can be implemented; in a non-working state, the landing gear is folded, the supporting arms are folded transversely in a staggered manner, and the positions of the supporting arms are kept by the locking mechanisms, so that the volume is reduced for convenient carrying and transporting.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a laterally staggered folding four-rotor aircraft. Background technique [0002] Compared with other aircraft, quadrotors fly more smoothly, can quickly switch between hovering, side flight and inverted flight states, and have good take-off and landing performance and maneuverability. They are very suitable for fixed-point reconnaissance, aerial photography, and aviation. Surveying and mapping and other tasks have a wide range of military and civilian uses. [0003] The rotor support arms and landing gear of traditional quadrotor aircraft usually adopt a fixed structure, which makes the aircraft have a large volume and brings a lot of inconvenience to the carrying and transportation process. Although some quadrotors also adopt folding structures, such as the German MD4-1000 aircraft, which adopts a folding structure in which the half-support arms are folded down, but the folded volume i...

Problems solved by technology

Patent CN302779997S proposes a folding quadrotor aircraft, the support arms of which are folded toward the outside. Although this folding method reduces the lateral width of the aircraft, it increases the longitudinal length of the aircraft after folding.

Therefore, although the several folding schemes involved in the above-mentioned patents all reduce the volume of the quadrotor aircraft to a certain extent, they all adopt plane folding schemes, and their folding joints are all limited to the same plane, and are not maximized. Make full use of the effective space around the fuselage
