Abstract

The invention discloses a combined type tilting rotor-wing helicopter. The aircraft has characteristics of vertical ascending and descending, hovering and high-speed forward flight; compared with a traditional helicopter, the flight speed is high; compared with a tilting rotor-wing aircraft, the control reliability is high. The aircraft comprises a main lifting power rotor wing, a tilting rotor wing, a tilting airfoil, a fixed airfoil, a fuselage body and an undercarriage. The main lifting power rotor wing is a coaxial reversing propeller double-rotor-wing system; the tilting rotor wing and the tilting airfoil can be rotated through an actuating mechanism along a rotary shaft. The aircraft needs to undergo a vertical flight state, a transition flight state and a vertical flight state from takeoff to flat flight. In a whole flight process, the main lifting power rotor wing provides main lifting power to the aircraft all the time, and attitude of the aircraft is mainly controlled through tilting of the tilting rotor wing and the tilting airfoil. The combined type tilting rotor-wing helicopter has advantages of the tilting rotor wing and a coaxial helicopter, and mechanism and control defects of the tilting rotor wing and the coaxial helicopter are overcome; meanwhile, the reliability of the mechanism and a control method is improved.

Description

technical field [0001] The invention relates to a compound tilting rotor helicopter, which belongs to the technical field of aviation products. Background technique [0002] Tilting-rotor aircraft is a new type of aircraft that combines the inherent advantages of vertical take-off and landing of helicopters with the high-speed and long-range performance of fixed-wing propeller aircraft. The V22 Osprey is a representative of the field of tilting-rotor aircraft. This kind of aircraft does not need to run during take-off and landing, and can also achieve a relatively fast flight speed during level flight. Therefore, this type of aircraft has broad application prospects, and is also an important direction for the development of aircraft. Although the tilt-rotor aircraft has many advantages, it has not been widely used, which is mainly limited by the safety hazards in its flight. When the tilt-rotor aircraft flies in the transition state, if there In the case of low or insuffic...
