Double-rotor aircraft with folding wings, and control method of double-rotor aircraft

Abstract

The invention discloses a double-rotor aircraft with folding wings, and a control method of the double-rotor aircraft, and relates to the field of aircrafts. The double-rotor aircraft comprises a fuselage, and the two wings respectively positioned at the two sides of the fuselage, wherein the two wings are hinged with the fuselage and can rotate around the longitudinal axis of the fuselage; rotorsystems are respectively arranged at the ends, far away from the fuselage, of the two wings; the rotor systems use the periodic variable pitch generated by a built-in automatic tilter to change the aerodynamic forces and aerodynamic moments of rotors, thus realizing the control of the pitch, yaw and rolling motions of the aircraft. The aircraft uses the same set of operating system when operatingin a helicopter mode and an aircraft mode. Compared with the existing vertical take-off and landing aircraft applying two sets of operating systems, the double-rotor aircraft provided by the inventionis simpler and more reliable in design, and does not need a redundant operating mechanism no matter during vertical take-off and landing or flat flight; the utilization rate of the structural components of the aircraft is improved, and the excessive structural weight is reduced. The double-rotor aircraft with the folding wings is applicable to aerial photography and can also be used for individual military investigation.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a double-rotor aircraft with folding wings and a control method thereof. Background technique [0002] Although the aerodynamic efficiency of traditional fixed-wing aircraft is relatively high, both hand-throwing and ejection have certain requirements on the venue, and hand-throwing launch requires the operator to be exposed to an open field, which is not conducive to the safety and concealment of the operator. Although quadrotor and multi-rotor aircraft are easy to take off, land and control, their flight speed, endurance time and flight radius are very limited due to the excessive flight resistance of the body, making it difficult to complete a wide range of reconnaissance tasks. The existing vertical take-off and landing aircraft utilizes the long endurance characteristics of fixed-wing aircraft and the better stability of quadrotors, and simply superimposes the functions of fixed-wing...

[0002] Although the aerodynamic efficiency of traditional fixed-wing aircraft is relatively high, both hand-throwing and ejection have certain requirements on the venue, and hand-throwing requires the operator to be exposed to an open field, which is not conducive to the safety and concealment of the operator.

Although quadrotor and multi-rotor aircraft are easy to take off, land and control, due to the excessive flight resistance of the body, their flight speed, endurance time and flight radius are very limited, making it difficult to complete a wide range of reconnaissance tasks

[0003] In summary, the existing vertical take-off and landing aircraft has the problems of complex structure and low aerodynamic efficiency
