Abstract

Glide vehicles can generally be launched in a wide airspace and speed range. A multidisciplinary analysis model, including geometric modeling, aerodynamics, structural mass, and flight performance disciplines, is established to extend the flight range of glide vehicles under multiple launch conditions. In the proposed model, the maximum flight range analysis in flight performance is taken as the core, and the analysis results is achieved by designing the flight guidance control system. The first three disciplines mainly provide the necessary data for the flight performance analysis. The flight performance discipline consists of four parts: flight control system design, optimal trajectory design, guidance law design, and trajectory simulation for maximum range analysis. To give an initial feasible design for the extended range problem of glide vehicle, an initial glide vehicle that meets the design constraints is designed by using U.S. Joint Standoff Weapon (JSOW) glide vehicle as a baseline. On this basis, the flight performance of the initial glide vehicle was analyzed under multiple launch conditions, which is close to the reported capability of JSOW. The multidisciplinary analysis model is used for the performance evaluation during the multidisciplinary design optimization of glide vehicles, and the range performance of optimized glide vehicle is increased to some extent.
