An overview of flight experiments of the high-speed flight demonstration (HSFD) project is presented. The project consists of two phases: Phases I and II. The Phase I flight experiment was conducted in Christmas Island, Republic of Kiribati, from October to December 2002. Through three flights, we have demonstrated the vehicle's ability to fly a steep approach path (up to 25°), which is characteristic of return flights of winged reentry vehicles, and have accumulated autonomous flight technologies needed for unmanned vehicles including take-off and landing. A flight experiment of Phase II was conducted at Esrange test site near Kiruna in Sweden from June to July 2003 in collaboration with Centre National d'Etudes Spatiales of France (CNES). Using the flight data, the vehicle's aerodynamic characteristics at a constant Mach number (0.8) over a wide range of angles of attack were estimated, and fully autonomous flight control technologies were demonstrated.
