Hyflex (Hypersonic Flight Experiment) was a NASDA reentry demonstrator prototype which was launched in 1996 on the only flight of the J-I launcher. It was a successor of OREX and was a precursor for the Japanese space Shuttle Hope.Hyflex tested the carbon-carbon heat shielding tiles that were intended to be used on HOPE as well as having the same body shaping in order to gather data on hypersonic lifting.
