【Abstract】 Reusable launch vehicles(RLV) provide a promising way to deliver space vehicles into orbit with less costs and better convenience. A multidisciplinary analysis tool is developed for the conceptual design of a two stage to orbit(TSTO) reusable launch vehicle with capacity of horizontal takeoff and horizontal landing.The tool consists of several analysis modules including propulsion, geometry, aerodynamics, weight, flight performance, thermal protection, stability and control. Each module uses the rapid analysis methods oriented to the conceptual design of the RLV. The usefulness of the tool is demonstrated by application of the RLV concept analyses. The application indicated that the comprehensive analyses and evaluations for can be completed rapidly by use of the tool. It is concluded that the tool developed in this study is quite helpful for the RLV conceptual design in terms of efficiency.更多还原
