RHRC EVALUATES X-43A AERODYNAMICS

Feb. 21, 2003 - Rolling Hills Research Corporation, a California Corporation, was selected by NASA Dryden Flight Research Center to evaluate the aerodynamics of the X-43A "Hyper-X" vehicle.  RHRC will also evaluate the DFRC six-degree-of-freedom simulation model of the X-43A.  The X-43A is a hypersonic SCRAM-JET vehicle program sponsored jointly by NASA Langley and NASA Dryden.  SCRAMJETs are unique in that they are air-breathing engines where the entire engine flowpath is supersonic.  The first operational test flight of the vehicle is currently scheduled for Summer-Fall 2003.  For addition information, visit NASA's web pages.
