HyShot
HyShot is a research project of The University of Queensland, Australiabr>Centre for Hypersonics to demonstrate the possibility of supersonic combustion under flight conditions using two scramjet engines, one designed by The University of Queensland and one designed by QinetiQ (formerly the MOD's Defence Evaluation & Research Agency). Overview The project has involved the successful launch of one engine designed by The University of Queensland, and one launch of the scramjet designed by the British company QinetiQ. Each combustion unit was launched on the nose of a Terrier-Orion Mk70 sounding rocket on a high ballistic trajectory, reaching altitudes of approximately 330 km. The rocket was rotated to face the ground, and the combustion unit ignited for a period of 6–10 seconds while falling between 35 km and 23 km at around Mach 7.6. The system is not designed to produce thrust. * The first HyShot flight was on 30 October 2001 but was a failure due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scramjet
A scramjet (supersonic combustion 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 compress the incoming air forcefully before combustion (hence ''ram''jet), but whereas a ramjet decelerates the air to speed of sound, subsonic velocities before combustion using shock cones, a scramjet has no shock cone and slows the airflow using shockwaves produced by its ignition source in place of a shock cone. This allows the scramjet to operate efficiently at extremely high speeds. Although scramjet engines have been used in a handful of operational military vehicles, scramjets have so far mostly been demonstrated in research test articles and experimental vehicles. History Before 2000 The Bell X-1 attained Supersonic speed#Supersonic flight, supersonic flight in 1947 and, by the early 1960s, rapid progress toward faster aircraft suggested that operational aircraft wo ...

Woomera Test Range
The RAAF Woomera Range Complex (WRC) is a major Australian military and civil aerospace facility and operation located in South Australia, approximately north-west of Adelaide. The WRC is operated by the Royal Australian Air Force (RAAF), a Service of the Australian Defence Force (ADF). The complex has a land area of or roughly the size of North Korea or Pennsylvania. The airspace above the area is restricted and controlled by the RAAF for safety and security. The WRC is a highly specialised ADF test and evaluation capability operated by the RAAF for the purposes of testing defence materiel. The complex has been variously known as the Anglo-Australian Long Range Weapons Establishment and then the Woomera Rocket Range; the RAAF Woomera Test Range and in 2013, the facility was reorganised and renamed to the RAAF Woomera Range Complex (WRC). The ground area of the WRC is defined by the Woomera Prohibited Area (WPA) and includes the Nurrungar Test Area (NTA); with a land area o ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are often used to launch instruments from above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about and the minimum for satellites is approximately . Due to their suborbital flight profile, sounding rockets are often much simpler than their counterparts built for orbital flight. Certain sounding rockets have an apogee between , such as the Black Brant X and XII, which is the maximum apogee of their class. For certain purposes, sounding rockets may be flown to altitudes as high as to allow observing times of around 40 minutes to provide geophysical observations of the magnetosphere, ionosphere, thermosphere, and mesosphere.

Telemetry
Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots ''tele'', 'far off', and ''metron'', 'measure'. Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand. Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data. A ''telemeter'' is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely u ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957.

Australian Defence Force
The Australian Defence Force (ADF) is the Armed forces, military organisation responsible for the defence of Australia and its national interests. It consists of three branches: the Royal Australian Navy (RAN), Australian Army and the Royal Australian Air Force (RAAF). The ADF has a strength of just over 89,000 personnel and is supported by the Department of Defence (Australia), Department of Defence alongside other civilian entities also members of the Australian Defence Organisation. During the first decades of the 20th century, the Australian Government established the armed services as separate organisations, with each service having an independent chain of command. In 1976, the government made a strategic change and established the ADF to place the services under a single headquarters. Over time, the degree of integration has increased, and tri-service headquarters, logistics, and training institutions have supplanted many single-service establishments. The ADF has been dep ...
