A take-off method for a shaft pusher tiltrotor aircraft

Abstract

The application discloses a shaft push tilting aircraft, which comprises a fuselage, a wing system, tiltable propulsion devices and axial propulsion devices, realizes vertical and short-distance take-off and landing, and is characterized in that the wing system comprises main wings and tail wings on both sides of the fuselage; the tiltable propulsion devices are two groups, symmetrically installed at the tips of the wings on both sides of the fuselage, and comprise power devices and rotors; and the axial propulsion devices are arranged along the axis of the fuselage, installed at the head or tail of the fuselage, and provide axial thrust. The application realizes safe landing of three engines in any failure combination, is more beneficial to the approval requirement of civil aviation approach waiting time, and replaces universal joints and power transmission shafts of traditional tilting rotors with simple structures. The application is different from short-distance take-off aircrafts such as ducted fan vector propulsion, and high-temperature hot flow sprayed by a tail nozzle of the short-distance take-off aircrafts can erode the fuselage and the runway, while the propulsion devices of the application are arranged along the axis of the fuselage, and high-temperature erosion caused by high-temperature hot flow is well avoided.
