- Abstract
The air breathing engine is one of the key technologies for completely reusable transportation systems from the ground to the orbit from a viewpoint of reliability enhancement and cost reduction. Re-cently, due to sluggish growth of launch demands opposite to those expected in the past, development of such reusable systems has slowed down, accompanied by reduction of funds, in spite that a change from the conventional exhaustive systems to reusable ones is inevitable from a historical angle. In such a situa-tion, it is more desired than ever before to perform low-cost flight experiments and demonstrations in development of reusable systems. In Japan Aerospace Exploration Agency, as a part of the precooled turbo jet engine development, a low-cost flight experiment of the engine system onboard a flight demon-strator has been proposed. In this experiment, the demonstrator with a wing body configuration, 4 meter in length and 450 kg in weight approximately, is designed to be dropped from a balloon at an altitude of 40 km and accelerated up to Mach 2 and above, during which the fundamental performance of the engine system is tested and the flight data are acquired. In this article, an overview of the flight experiment and the current development status of the flight demonstrator are introduced.
