The de Havilland Propellers Blue Streak was a British Intermediate-range ballistic missile (IRBM), and later the first stage of the Europa satellite launch vehicle. Blue Streak was cancelled without entering full production.
The Europa rocket was an early expendable launch system of the European Launcher Development Organisation (ELDO), which was the precursor to the European Space Agency (ESA). It was developed with the aim to delivering space access technology, and more specifically to facilitate the deployment of European-wide telecommunication and meteorological satellites into orbit.
A scramjet 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, but where as a ramjet decelerates the air to 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.
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 used to launch instruments from 48 to 145 km above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km and the minimum for satellites is approximately 121 km. Certain sounding rockets have an apogee between 1,000 and 1,500 km, such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km.
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program developed in the late 1990s. It set several airspeed records for jet aircraft. The X-43 is the fastest jet-powered aircraft on record at approximately Mach 9.6.
A skyhook is a proposed momentum exchange tether that aims to reduce the cost of placing payloads into low Earth orbit. A heavy orbiting station is connected to a cable which extends down towards the upper atmosphere. Payloads, which are much lighter than the station, are hooked to the end of the cable as it passes, and are then flung into orbit by rotation of the cable around the center of mass. The station can then be reboosted to its original altitude by electromagnetic propulsion, rocket propulsion, or by deorbiting another object with the same kinetic energy as transferred to the payload.
The European Launcher Development Organisation (ELDO) is a former European space research organisation. It was first developed in order to establish a satellite launch vehicle for Europe. The three-stage rocket developed was named Europa, after the mythical Greek goddess. Overall, there were 10 launches that occurred under ELDO's funding. The organisation consisted of Belgium, Britain, France, Germany, Italy, and the Netherlands. Australia was an associate member of the organisation.
The DARPA FALCON Project was a two-part joint project between the Defense Advanced Research Projects Agency (DARPA) and the United States Air Force (USAF) and is part of Prompt Global Strike. The first part of the project aimed to develop a Small Launch System (SLS) capable of accelerating hypersonic gliding weapons as well as launching small satellites into Earth orbit. The second part of the project aimed to develop Hypersonic Weapon Systems (HWS): a short term high performance hypersonic gliding weapon previously named the X-41 Common Aero Vehicle (CAV) that could be launched from Expendable Launch Vehicles (ELV), Reusable Launch Vehicles (RLVs), Hypersonic Cruise Vehicles (HCV), or Space Maneuvering Vehicles (SMP), and a long term hypersonic cruise aircraft named the Hypersonic Cruise Vehicle (HCV). This two-part program was announced in 2003 and continued into 2006.
Scramjet programs refers to research and testing programs for the development of supersonic combustion ramjets, known as scramjets. This list provides a short overview of national and international collaborations, and civilian and military programs. The USA, Russia, India, and China (2014), have succeeded at developing scramjet technologies.
Lockheed L-301 was an experimental air-breathing hypersonic aircraft project. It was developed by the NASA and United States Air Force (USAF) organization National Hypersonic Flight Research Facility, with Skunk Works as the prime contractor. In January 1977, the program was "tentatively scheduled to operate two vehicles for eight years and to conduct 100 flights per vehicle." NASA discontinued work on L-301 and NHRF in September 1977 due to budget constraints and lack of need.
The Tupolev Tu-2000 was a planned hypersonic flight experimental aircraft designed by the Tupolev design bureau. It was intended to test technologies for a single-stage-to-orbit aerospaceplane and also the Tupolev Tu-360 intercontinental bomber.
Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020.
ALV X-1 was the first and only flight of the ATK Launch Vehicle (ALV) sounding rocket developed by Alliant Techsystems. The launch occurred from LP-0B at the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Flight Facility. This mission carried the SOAREX-VI and Hy-BoLT experiments as payloads when it launched at 09:10 GMT on August 22, 2008. The vehicle was terminated 20 seconds into flight after veering too far off course.
HyShot is a research project of The University of Queensland, Australia 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.
The HSTDV is an unmanned scramjet demonstration aircraft for hypersonic flight. It is being developed as a carrier vehicle for hypersonic and long-range cruise missiles, and will have multiple civilian applications including the launching of small satellites at low cost. The HSTDV program is being run by the Defence Research and Development Organisation (DRDO).
The Boeing Small Launch Vehicle, or SLV, is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of 100 pounds (45 kg) into low Earth orbit. The program is proposed to drive down launch costs for small satellites as low as US$300,000 per launch ($7,000/kg) and could be fielded by 2020.
The DARPA XS-1 was an experimental spaceplane/booster with the planned capability to deliver small satellites into orbit for the U.S. Military. It was reported to be designed to be reusable as frequently as once a day, with a stated goal of doing so for 10 days straight. The XS-1 was intended to directly replace the first stage of a multistage rocket by taking off vertically and flying to hypersonic speed and high suborbital altitude, enabling one or more expendable upper stages to separate and deploy a payload into low Earth orbit. The XS-1 would then return to Earth, where it could ostensibly be serviced fast enough to repeat the process at least once every 24 hours.
The Mobile Rocket Base, abbreviated MORABA, is a department of the DLR Space Operations and Astronaut Training in Oberpfaffenhofen near Munich. Since the 1960s, the MORABA has performed scientific high altitude research missions with unmanned rockets and balloons, and has developed the required mechanical and electrical systems. Their operational areas include upper atmosphere research, microgravity research, astronomy, geophysics, materials science, as well as hypersonic research.
Scramspace was a hypersonic engine research project established by the University of Queensland, Australia's Centre for Hypersonics. It was a 1.8 meter long, free-flying, hypersonic scramjet. A scramjet is fundamentally an air-breathing engine that travels at hypersonic velocities. Built in Brisbane at an estimated cost of $14 million, it took approximately 3 years to complete. Scramspace was supposed to fire at a hypersonic velocity of Mach 8 or 8600 km/hour (5343 mph) but the flight-test turned out to be a failure and the rocket engine and the payload plummeted in the North Sea off the coast of Norway.
Hypersonix Launch Systems is an Australian space startup developing scramjet and scramjet-based access-to-space technology. In particular, the company is focused on reusable "green-fuelled" launch technology. The company specialises in hypersonic vehicle and scramjet engines to provide sustainable and affordable access to space.
