AbstractThe Balloon-based Operation Vehicle(BOV) originally developed for the micro-gravity experiments is modified as a supersonic flight demonstrator of a sub-scale precooled turbojet engine developed in JAXA. In the supersonic flight demonstration, the vehicle is raised by a high-altitude balloon up to a 40 km altitude and dropped to accelerate the vehicle to a supersonic velocity. To extend the flight time for an engine combustion test in the super sonic environments, the vehicle is redesigned in a wing-body configuration with a main delta wing and movable vertical and horizontal tail wings so that it can be pulled out above an altitude of 5km. As a result, the vehicle is capable of reaching the maximum flight Mach number of 2 with the dynamic pressure of 25 kPa at an altitude of 17km, realizing the engine test time longer than 30 sec. The flight demonstration is currently scheduled in 2009. In this article, an overview of the aerodynamic characteristics of the flight demonstrator and the flight trajectory plan is presented.
