Parallel double-waverider two-stage injection aircraft horizontal stage separation design method

Abstract

The invention discloses a horizontal stage separation design method for a parallel double-waverider two-stage injection aircraft. The horizontal stage separation design method comprises the following steps: constructing a combined body structure of an orbit-stage waverider aircraft and a boosting-stage waverider aircraft; when the flight of the assembly structure reaches an interstage separation condition, the lift force borne by the two side wings of the boosting-stage waverider aircraft is unbalanced, and then the assembly structure rolls by 90 degrees in the lateral direction of the aircraft body; under the condition that the lateral rolling of the combined body structure is kept by 90 degrees, the track-level waverider aircraft is pushed by the power of the track-level waverider aircraft to perform horizontal separation action along the upper surface of the boosting-level waverider aircraft; after the orbit-level waverider aircraft is separated from the boosting-level waverider aircraft, the orbit-level waverider aircraft continues to laterally roll by 90 degrees and climbs to a target orbit, and the boosting-level waverider aircraft reversely rolls by 90 degrees to recover an initial flight state, so that horizontal-level separation of the orbit-level waverider aircraft and the boosting-level waverider aircraft is realized. According to the horizontal interstage separation method, the problems of high pressure, high heat flow and stability in the conventional separation process under the hypersonic speed condition are solved.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a design method for separating the horizontal stages of a parallel double waverider two-stage orbiting aircraft. Background technique [0002] The two-stage orbiting vehicle has been extensively studied as the next-generation reusable space-to-ground transportation system with low cost, high efficiency, and high reliability. The horizontal take-off and landing two-stage orbiter consists of an air-breathing powered booster stage and a reusable rocket-powered orbital stage. Horizontal take-off and landing two-stage orbiting aircraft generally carry the orbital stage on the back of the booster stage to take off at a conventional airport. , the booster stage maneuvers and controls to return to the airport by itself, and the orbital stage accelerates to climb into orbit under the propulsion of the rocket. After completing the orbital mission, the orbital stage glides back to land. ...
