Optimal Trajectory Design for D-SEND＃2 Vehicle
JAXA is investigating a new supersonic flight test named Drop test for Simplified Evaluation of Non-symmetrically Distributed sonic boom (D-SEND) to verify aerodynamic design technology for use with the low sonic boom airplane configuration. D-SEND comprises two series of balloon drop tests: D-SEND＃1 and D-SEND＃2. This paper describes the flight trajectory of D-SEND＃2. Measurement requirements for sonic boom are first summarized. The most desirable flight condition is then derived for satisfying the measurement condition. Finally, flight trajectories are optimized for downrange performance using the simplex method. Results show that an area exists for which separation must be avoided to satisfy the measurement requirements. Furthermore, important knowledge is obtained for designing a guidance and control system.
