A scramjet (supersonic combustion ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion, the airflow in a scramjet is supersonic. -- NASA Langley Arc-Heated Scramjet Test Facility: Langley Foot Diameter Vacuum Sphere. This is a photograph of the foot diameter vacuum sphere, located behind Building B. The photo was taken in , several years prior to construction of the Mach 7 Scramjet Test Facility (now called the Arc-Heated Scramjet Test Facility). NASA Langley's specialized research facilities enable the center to perform world-class research in aeronautics, atmospheric sciences and space technology. Langley's wind tunnels allow engineers to conduct testing that encompasses the entire speed range from 0 mph to nearly M or approximat mph. The NASA Langley Scramjet Test Complex consists of five propulsion facilities which cover a wide spectrum of supersonic combustion ramjet (scramjet) test capabilities. These facilities permit observation of the effects on scramjet performance of speed and dynamic pressure from Mach to nearorbital speeds, engine size from Mach 4 to 7, and.

Scramjet Test Facility (CHSTF)6,7. This wind-tunnel has a 96 in. long test chamber with a height of 42 in. and a width of 30 in., and was designed specifically for free-jet testing of complete scramjet flowpaths. This test program utilized the Mach facility nozzle, which has a square exit with dimensions of m x m (in x in.). The current experimental study at Mach 7 was carried out to investigate the viscous flow effects in a scramjet inlet with a fixed geometry operating at Mach In the Mach to 8 speed range, the complex includes a direct-connect combustor test facility, two small-scale complete engine test facilities, and a large-scale complete engine test facility. The XA's second flight at 28 meters was the first successful demonstration of scramjet technology, which eventually will propel an aircraft into suborbital flight above the atmosphere at.

In tests were made in Australia under the guidance of Professor Ray Stalker in the T3 ground test facility at ANU. [3] The first successful flight test of a Scramjet was performed by Russia in It was an axisymmetric hydrogen-fueled dual-mode scramjet developed by Central Institute of Aviation Motors (CIAM), Moscow in the late s. The Langley Research Center (LaRC or NASA Langley) located in Hampton, Virginia, United States, is the oldest of NASA's field centers. It directly borders Langley Air Force Base and the Back River on the Chesapeake has focused primarily on aeronautical research, but has also tested space hardware at the facility, such as the Apollo Lunar arters: Hampton, Virginia, United States. Template:Seriesbox aircraft propulsion A scramjet (supersonic combusting ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to forcefully compress the incoming air before combustion (hence ramjet), but a ramjet decelerates the air to subsonic velocities before combustion, while. ramjet test facility which is used for ground tests of supersonic air breathing propulsion systems. Conceptual design of a direct connected ramjet test facility is performed. 1.
