Abstract

The invention discloses a semi-active rotor type reentry and return device, comprising: an aircraft body, N driving rotor devices, M rotating rotor devices and a transmission device; the driving rotor devices are evenly distributed in the circumferential direction of the aircraft body, and / or, Arranged along the axial direction of the aircraft body; the rotating rotor device is evenly distributed in the circumferential direction of the aircraft body, and / or arranged along the axial direction of the aircraft body; force transmission is performed between the driving rotor device and the rotating rotor device through a transmission device. The invention utilizes the high-speed aerodynamic characteristics of the reentry process of the aircraft to generate power by driving the rotor device, which is transformed by the transmission device to push the rotating rotor device to rotate to generate lift that hinders the aircraft from descending, thereby reducing the reentry speed of the aircraft; adopts semi-active deceleration In this way, the aerodynamic deceleration of the aircraft re-entry process can be realized more effectively.

Description

technical field [0001] The invention belongs to the technical field of aircraft re-entry and return, in particular to a semi-active rotor type re-entry and return device. Background technique [0002] With the development of my country's space technology, the need for re-entry and return of aircraft is becoming more and more urgent. When the aircraft re-enters and returns from the space orbit, the re-entry speed is high, which often produces a large aerodynamic heating. At present, for the re-entry and return of the aircraft, two technologies are mainly used for the lift body type aerodynamic return and the parachute type aerodynamic return. The lift body re-entry and return is represented by the space shuttle. The re-entry vehicle adopts the winged mode. Through the horizontal flight, the wings of the aircraft are used to generate lift, which prolongs the re-entry stroke of the aircraft, thereby reducing the aerodynamic heat during the entire re-entry process. The need fo...
