Cruise vehicle with variable wings

Abstract

The invention provides a cruise vehicle with variable wings, comprising a vehicle body, vehicle wings, acceleration section tail wings and cruise section tail wings. The vehicle wings are connected with the vehicle body through a wing varying mechanism, the wing varying mechanism comprises a swinging rod, a wing rod, a triangular connection piece, a push rod, a piston and an actuating cylinder, and the vehicle wings are fixedly connected on the wing rod; the piston is driven by external driving force to move in the actuating cylinder front and back, and the external driving force is transferred to the wing rod for connecting the vehicle wings through the push rod and the triangular connecting rod, and thus the control on sweepback angles of the vehicle wings and positions of the vehicle wings relative to the vehicle body is realized. The vehicle body and the vehicle wings are connected through the wing varying mechanism, the piston of the wing varying mechanism is driven by the external driving force, and the external driving force is transferred to the vehicle wings through the triangular connection piece, and thus the control on the variation of the sweepback angles of the vehicle wings and the variation of the positions of the vehicle wings relative to the vehicle body is realized, and the cruise vehicle with the variable wings, disclosed by the invention, has the advantages of simplicity in realizing, light weight and small volume, and can meet use requirements of the cruise vehicle.

Description

technical field [0001] The invention relates to a variable-wing cruising aircraft, in particular to a cruising aircraft with a variable wing sweep angle and capable of supersonic flight at the subsonic end stage of the cruising section, and belongs to the technical field of aircraft design. Background technique [0002] The cruising aircraft can achieve long-endurance and long-range flight, and can achieve strikes on long-distance targets by launching outside the defense zone. Most of the flight time of the cruising aircraft is in the cruising state of constant altitude and constant speed and level flight. In this state, the cruising aircraft has the highest lift-to-drag ratio and the lowest unit fuel consumption. However, as the modern battlefield situation continues to change, for cruise aircraft, it is required to adapt to different flight states of high and low altitudes and high and low speeds at the same time, so as to break through the complete defense system of the a...

AI Technical Summary

Problems solved by technology

At present, hydraulic transmission or crank-slider mechanism is usually used to change the sweep angle, but the hydraulic transmission is bulky and heavy, and the slider on the crank-slider mechanism is driven by a screw, which has the disadvantages of heavy structure and slow speed. Therefore, the above two methods of changing the sweep angle are not suitable for cruise aircraft that need to adapt to different flight states.
