小型自動着陸実験(ALFLEX)計画

National Aerospace Laboratory and National Space Development Agency have been cooperating to research the unmanned H-II rocket orbiting space reentry vehicle HOPE. In the research, they are conducting the scale model automatic landing flight experiment(ALFLEX) program. The purpose of the ALFLEX program is to establish the fundamental technology for the HOPE automatic landing, especially design method of the HOPE navigation, guidance and control system and to evaluate the method by automatic landing flight experiment of a dynamically scaled HOPE model. The experiment procedure is to carry the scaled automatic landing test vehicle by a mother helicopter, drop the model at the altitude 1500m at the speed of 46m/s. The test vehicle automatically fly and land on a 1000m runway. This paper describes an introduction of the ALFLEX program.
