Foldable Y shaped three axis two-layer six rotorcraft

Abstract

The invention relates to a foldable Y-shaped aircraft with three shafts and two-layered six rotor wings, which overcomes the defects of existing aircrafts with multiple rotor wings that opposite torque forces that are generated by corresponding positive and negative rotor wing groups counteract with each other through a supporting arm, as the supporting arm has a certain length and large structural weight loss, the torque moment counteracting effect is limited, and as the single-layered rotor wings are positioned on a same horizontal plane, the aircraft has limited motion power. The structure of the foldable Y-shaped aircraft with three shafts and two-layered six rotor wings consists of a main body, three groups of electric motor installation hood, three groups of supporting arms that connect the electric motor installation hood and the main body, three groups of rotor wings and a plurality of fasteners; each group of rotor wings has two rotor wings that are respectively arranged at an upper top end and a lower top end of the electric motor installation hood and are the positive and negative rotor wings which have the same geometrical shape and the opposite rotary direction. As the upper and lower two rotor wings of each rotor wing group are the positive and negative rotor wings that have the same geometrical shape and the opposite rotary direction, the torque forces generated by the rotation of the upper and lower rotor wings can counteract with each other, thus realizing the self-equilibrium during the movement of the aircraft, and the foldable Y-shaped aircraft has simple structure and better flexibility and stationarity, can be folded and is convenient for carry and transportation.

Description

technical field [0001] The invention relates to a foldable "Y" type three-axis double-layer six-rotor aircraft, which can be widely used in military and civilian fields. Background technique [0002] Rotorcraft with functions such as vertical take-off and landing and hovering can be roughly divided into two categories. [0003] One type is rotor helicopters, which roughly include single rotor, double rotor, tilt rotor and other structural forms, typical representatives such as the MH-16 helicopter of the American McDonnell Douglas, the Russian Ka-29 helicopter, the tilting helicopters of the American Boeing Company and Bell Corporation. Rotorcraft V-22 and V-44 etc. Single-rotor helicopters need a tail rotor structure to offset the torsion produced by the rotor on the body, and tilt-rotors need to tilt the rotor surface in the state of vertical take-off and flat flight. The common problems are that the diameter of the main propeller is larger than that of the airframe, the...

AI Technical Summary

Problems solved by technology

Its defect is: the torsional forces generated by the two sets of positive and negative rotors are transmitted through the support arms to offset each other. Due to the length of the connecting support arms and mechanical fixation, the weight loss of the support arm structure is large, and the torque offset effect is limited. ; Second, the number of its support arms is generally equal to the number of rotors, and both are an even number greater than two. The support arms are fixed on the same horizontal plane, cannot be retracted and folded, are not easy to carry and transport, and the flexibility of movement is limited; Third, The rotors are on the same horizontal plane, and they are all single-layer rotors, so the power of the aircraft is limited
