Go for launch
On May 18 , 2016 , a Eruca vesicaria sativa launching at the Woomera Test Range in South Australia comport a hypersonic mental test fomite for a successful examination flight at Mach 7.5 — more than seven times the speed of strait . The successful test was an experimental milestone on the way to a horizontal flight test of an Australian - built " scramjet " engine in 2018 . Hypersonic jet engines could one sidereal day impel rider aircraft around the world in only a few hr , or they could be used as resuable launch vehicles to carry satellite into range .

New engine
" Scramjets " — forgetful for Supersonic Combustion Ramjet — can manoeuver at more than five time the swiftness of sound , but not at slower amphetamine . data-based scramjet flights use rocket to advance them to focal ratio above Mach 5.A garden rocket launch planned for November 2017 will carry the Australian scramjet railway locomotive to high-pitched altitudes for its first vertical hypersonic test flight .
Hypersonic flight
The Australian scramjet railway locomotive is being spring up as part of a joint American - Australian research program shout out HIFiRE ( myopic for Hypersonic International Flight Research and Experimentation ) that involvesNASA , the U.S. Air Force and the Australian Defence Department . The scramjet railway locomotive is designed and build by scientists and locomotive engineer at the University of Queensland . The first horizontal test flight of steps using the new engine , dubbed HIFiRE 8 , is design for 2018 .
At the controls
The most recent mental test was conducted at the Woomera Test Range by staff from Australia ’s Defence Science Technology Group ( DSTG ) . This look-alike shows DSTG engineering specialist Hans Alesi in the Woomera mastery room for the hypersonic test , which carried the test vehicle to an altitude of 173 air mile ( 278 km ) . On its direction back to the priming , the test fomite attain a top amphetamine of Mach 7.5 — seven and a half time the velocity of sound , or about 5,700 mph ( 9,200 km / h ) .
In the Outback
The Woomera Test Range is the large land - based military range in the world , cover up about 47,000 straight Roman mile ( 122,000 square kilometers ) of the South Australian outback . The range of a function was established by the British and Australian governments for rocket tests presently after World War II , and a remote part of the range of a function was used for seven British nuclear bomb calorimeter tests between 1956 and 1963.This image show a gamy frequency aerial raiment near Woomera , used for telemetry communicating with garden rocket in trajectory .
Blazing fast
The high speeds of hypersonic aircraft cause intense heat from atmosphere friction on the surface of the fuselage , and scramjet engines themselves operate at very mellow internal temperature that would melt metal engines . The Australian scramjet is make entirely from lightweight carbon composites that can withstand temperature of up to about 2,900 level Fahrenheit ( 1,600 degrees Celsius ) .
High-speed travel
Hypersonic passenger aircraft power by scramjets have the potential to thin a stumble from London to Sydney to just 2 hour , but such commercial-grade aircraft are probably ten from being developed , grant to the Australian research worker . However , scramjets could before long be in economic consumption as resuable launch vehicles to put small satellites into orbit , because they can carry more payload than a rocket using liquified O to burn propellent .
