That's the idea behind a different propulsion system called "SCRAMJET", or Supersonic Combustion Ramjet: The oxygen needed by the engine to combust is taken from the atmosphere passing through the vehicle, instead of from a tank onboard. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital 7-Hypersonic Airbreathing Propulsion (Aiaa Education) by William H. All current spacecraft use chemical rockets (bipropellant or solid-fuel) for launch, though some (such as the Pegasus rocket and SpaceShipOne) have used air-breathing engines on their first stage. Associate Professor Smart did fundamental work on new inlet designs while working at the Hypersonic Air-Breathing Propulsion Branch at NASA`s Langley Research Center in Virginia. Professor of mechanical and aerospace engineering and the principal investigator for a five-year research project on air-breathing propulsion. The RLV-TD will act as a flying test-bed to evaluate various technologies — hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air breathing propulsion. The RLV is intended to test several indigenous capabilities, including hypersonic flight, autonomous landing, and powered cruise flight, hypersonic flight using air breathing propulsion. Of strong nonlinearities, the use of improved turbulence models and unstructured grids in numerical simulations, the need for accessible validation data, and the refinement of mission objectives for Hypersonic Air-Breathing Propulsion (HABP). March 11, 2009 — A new center to develop the analytical tools needed to design the engines for a future hypersonic aircraft – one that could fly up to 12 times the speed of sound – is being established at the University of Virginia under space shuttle, it would land under power rather than glide in," said Jim McDaniel, a U.Va. Carry more payloads: An advantage of hypersonic air breathing (typically scramjet) vehicle is avoiding or at least reducing the need for carrying oxidizer.75% of the entire assembly weight is liquid oxygen.
