Folding-wing dual-rotor aircraft and control method thereof

Abstract

The invention discloses a double-rotor aircraft with folding wings and a control method thereof, and relates to the field of aircraft. The aircraft includes a fuselage and wings respectively located on both sides of the fuselage. The two wings are hinged on the fuselage and can wind around the aircraft. The longitudinal axis of the body rotates, and the ends of the two wings far away from the fuselage are equipped with a rotor system. The rotor system uses the period variable pitch generated by the built-in automatic tilter to change the aerodynamic force and aerodynamic moment of the rotor to realize the pitch and yaw of the aircraft. and roll motion control. The aircraft shares a control system when working in helicopter mode and airplane mode. Compared with the existing vertical take-off and landing aircraft using two sets of control systems, the design of the present invention is more convenient and reliable, and the aircraft has no redundant control mechanism no matter in the process of vertical take-off and landing or level flight, which improves the utilization rate of the structural components of the aircraft. Reduced excess structural weight. The invention is suitable for aerial photography and can also be used for individual soldier 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...

Problems solved by technology

[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
