Air-based launching system and method based on subtransonic aerial carrier

Abstract

The invention belongs to the technical field of aircrafts, and particularly relates to an air-based launching system and method based on a subtransonic aerial carrier. The system comprises an aerial carrier and an aerospace vehicle. According to the invention, the mode of a large-scale subtransonic layout aircraft loaded with an aerospace vehicle air launching system with symmetrically-distributed outer storage tanks is adopted; for mounting type air-based launching, a put-in type cold launching method is adopted; two cold launching methods, namely a weightlessness and negative overload method and a jumping, rolling and reverse flying launching method, are adopted for back-loaded air-based launching; a subtransonic-speed aerial carrier aerodynamic layout is adopted; the cost of launching a heavy reusable aerospace vehicle is greatly reduced, the engineering realizability is considered, the proportion of the injection weight to the total take-off weight is greatly increased, and the aerospace vehicle can be used as a sky-ground round-trip aircraft, an air-breathing propulsion hypersonic aircraft or a boosting gliding hypersonic aircraft. The aerial carrier adopts a static stable aerodynamic layout design with a high lift-drag ratio, and a flight control system is simple and has engineering realizability.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a space-based launch system and a launch method based on a sub-transonic carrier aircraft. Background technique [0002] The existing technology closest to the present invention is the "White Knight II" system and the "Stratospheric Launcher" system, which adopt a double-fuselage layout subsonic aircraft, mount the aerospace vehicle under the central wing bridge, and bring it into the After being released at the bottom of the stratosphere, it is separated to a safe distance, ignited and launched in the air, and the aerospace vehicle uses its own lift surface to assist climbing and adjust its attitude, or completely rely on the rocket's vector control device to adjust its attitude, and then rely on rocket power to propel it into the Earth's low-Earth orbit. [0003] Once loaded with heavy projectiles, the wingspan and main launch outer wheelbase of dual-fuselage strai...
