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 supersonic 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 5 km. 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 17 km, 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., 形態: カラー図版あり, 資料番号: AA0064303024, レポート番号: JAXA-SP-08-009}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {高々度気球を用いた予冷ターボジェットエンジン飛行実証機の空力性能}, volume = {JAXA-SP-08-009}, year = {2009} }
