Keywords: Hyper-X and Pegasus Launch Vehicle, A Three-Foot Model of the Hypersonic Experimental Research Vehic DVIDS704237.jpg en The configuration of the X-43A Hypersonic Experimental Research Vehicle or Hyper-X attached to a Pegasus launch vehicle is displayed in this three-foot-long model at NASA's Dryden Flight Research Center Edwards California Hyper-X the flight vehicle for which is designated as X-43A is an experimental flight-research program seeking to demonstrate airframe-integrated air-breathing engine technologies that promise to increase payload capacity for future vehicles including hypersonic aircraft faster than Mach 5 and reusable space launchers This multiyear program is currently underway at NASA Dryden Flight Research Center Edwards California The Hyper-X schedule calls for its first flight later this year 2000 Hyper-X is a joint program with Dryden sharing responsibility with NASA's Langley Research Center Hampton Virginia Dryden's primary role is to fly three unpiloted X-43A research vehicles to validate engine technologies and hypersonic design tools as well as the hypersonic test facility at Langley Langley manages the program and leads the technology development effort The Hyper-X Program seeks to significantly expand the speed boundaries of air-breathing propulsion by being the first aircraft to demonstrate an airframe-integrated scramjet-powered free flight Scramjets supersonic-combustion ramjets are ramjet engines in which the airflow through the whole engine remains supersonic Scramjet technology is challenging because only limited testing can be performed in ground facilities Long duration full-scale testing requires flight research Scramjet engines are air-breathing capturing their oxygen from the atmosphere Current spacecraft such as the Space Shuttle are rocket powered so they must carry both fuel and oxygen for propulsion Scramjet technology-based vehicles need to carry only fuel By eliminating the need to carry oxygen future hypersonic vehicles will be able to carry heavier payloads Another unique aspect of the X-43A vehicle is the airframe integration The body of the vehicle itself forms critical elements of the engine The forebody acts as part of the intake for airflow and the aft section serves as the nozzle The X-43A vehicles were manufactured by Micro Craft Inc Tullahoma Tennessee Orbital Sciences Corporation Chandler Arizona built the Pegasus rocket booster used to launch the X-43 vehicles For the Dryden research flights the Pegasus rocket booster and attached X-43 will be air launched by Dryden's B-52 Mothership After release from the B-52 the booster will accelerate the X-43A vehicle to the established test conditions Mach 7 to 10 at an altitude of approximately 100 000 feet where the X-43 will separate from the booster and fly under its own power and preprogrammed control NASA Identifier NIX-EC97-44054-2 2009-09-23 Glenn Research Center https //www dvidshub net/image/704237 704237 2012-10-10 15 29 WASHINGTON DC US PD-USGov Langley Research Center Images from DoD uploaded by Fæ
