Hypersonic speed air inlet channel shape-preserving fairing scheme comprising folding wings

Abstract

The invention discloses a hypersonic speed air inlet channel shape-preserving fairing scheme comprising folding wings. The hypersonic speed air inlet channel shape-preserving fairing scheme comprises a resistance reduction unit, a plugging unit and a folding wing mechanism. One end of the resistance reduction unit is connected with the outer wall face of the aircraft, the other end of the reducing unit is connected with one end of the blocking unit, and the other end of the blocking unit is connected with the outer wall face of the bottom of the air inlet channel. A plugging structure is arranged on the plugging unit; the folding wing mechanism is arranged on the resistance reduction unit and has a first state and a second state; when the folding wing mechanism is in the first state, the folding wing mechanism is folded in the resistance reduction unit; when the folding wing mechanism is in the second state, the folding wing mechanism is unfolded outside the resistance reduction unit to provide negative lift force for the resistance reduction unit, so that the resistance reduction unit, the plugging unit and the folding wing mechanism are separated from the aircraft. Separation can be achieved only through aerodynamic force by means of the mode of popping up the small wings, and the contradiction that reduction of resistance and guarantee of sufficient separation torque of the fairing cannot be taken into consideration at the same time is effectively solved.

Description

technical field [0001] The invention relates to the technical field of aircraft air intakes, in particular to a scheme for a hypersonic air intake conformal fairing with folding wings. Background technique [0002] The fairing was first proposed for rocket transportation payloads, and is used to prevent the payload from being affected by external harmful environments such as aerodynamic force, aerodynamic heat, and vibration. The common structure is the clam shell type (two halves), which is composed of the end, the front cone section, the cylinder section, the inverted cone section, and the longitudinal and transverse separation mechanisms. [0003] For air-breathing hypersonic vehicles, in order to ensure the normal operation of the hypersonic inlet, it is often necessary to rely on other flight platforms, such as mounted aircraft and booster rockets. The hypersonic vehicle is sent to the specified flight altitude by the flight platform, and makes it reach the specified i...
