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.

    本发明属于飞行器技术领域,具体涉及基于亚跨声速载机的空基发射系统及发射方法;包括载机、空天飞行器;本发明采用大型亚跨声速布局飞机装载携带对称分布的外贮箱的空天飞行器空中发射系统和模式;对于挂载式空基发射,采用投放式冷发射方法;对于背载式空基发射采用两种冷发射方法:失重和负过载方法、跃起滚转倒飞投放方法;采用亚跨声速载机气动布局;解决大幅度降低发射重型可重复使用空天飞行器成本并考虑了工程实现性问题,大幅度提高入轨重量占起飞总重比例的问题,作天地往返飞行器,吸气式推进高超声速飞行器,或者助推滑翔式高超声速飞行器使用,且载机为高升阻比的静稳定气动布局设计,飞控系统简单且具备工程可实现性。
