Space Propulsion Group was founded in 1999 by Arif Karabeyoglu, Brian Cantwell, and others from Stanford University to develop high regression-rate liquefying hybrid rocket fuels. They have successfully fired motors as large as 12.5 in (32 cm). diameter which produce 13,000 lbf (58,000 N) using the technology and are currently developing a 24 ...
Successful tests of an oxidiser (both air and oxygen) cooled combustion chamber were conducted by EADS-Astrium at Institute of Space Propulsion in 2010 In 2011, hardware testing of the heat exchanger technology "crucial to [the] hybrid air- and liquid oxygen-breathing [SABRE] rocket motor" was completed, demonstrating that the technology is viable.
The design space constraints of SSTO vehicles were described by rocket design engineer Robert Truax: Using similar technologies (i.e., the same propellants and structural fraction), a two-stage-to-orbit vehicle will always have a better payload-to-weight ratio than a single stage designed for the same mission, in most cases, a very much better ...
In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed, each having its own drawbacks and advantages.
To be used on @Isispace and @U-space platforms for French and European missions. Modular Thruster with up to 4 nozzles per PPSCU. AB 360 Space: Washington DC, United States CLEPS X-100, CLEPS C100 hybrid Thrusters, Combined Liquid Electric Propulsion Systems, Methane/ Oxygen Ion Thrusters
Skylon has its origins within a previous space development programme for an envisioned single-stage-to-orbit (SSTO) spaceplane, known as HOTOL. [14] In 1982, when work commenced on the HOTOL by several British companies, there was significant international interest to develop and produce viable reusable launch systems, perhaps the most high-profile of these being the NASA-operated Space Shuttle.
Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel. All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some [ note 3 ] have used air-breathing engines on their first stage .
SpaceShipOne ranks among the world's first spaceplanes in the first 50 years of human spaceflight, with the North American X-15, Space Shuttle, Buran, and Boeing X-37. SpaceShipOne is the second spaceplane to have launched from a mother ship , preceded only by the North American X-15 .
