They are investigating new configurations in collaboration with NASA's Hypersonic Airbreathing Propulsion Branch at Langley Research Center in Virginia. Apparently, Chinese developers have abandon to waste time on the hypersonic air-breathing propulsion system but choose a conventional rocket power system to realize Single-stage-to-orbit. 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. I found his book to be a great resource for information on the current progress of hypersonic air-breathing propulsion engines. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital 7-Hypersonic Airbreathing Propulsion (Aiaa Education) by William H. Ground test hypersonic propulsion and vehicle concepts. Hypersonic Aerothermodynamics (Aiaa Education Series) By John J. 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. 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. 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. Mentor: Troy Middleton, Hypersonic Airbreathing Propulsion Branch, Currently, propulsion-airframe integrated scramjets are one of the most promising airbreathing propulsion systems for access to space. We are currently working on uncertainty quantification of hypersonic air-breathing propulsion (at our PSAAP Center), low-boom supersonic aircraft, and high-speed re-entry vehicles, among other things.

Experiment's Success May Significantly Contribute To Development Of Future High-Speed, Air-Breathing Jet Engines A hypersonic propulsion resear| Published: Sun, Jul 08, 2012 | Aero-News Network. 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. An orbiter with a drop tank that carries the boost phase propellant in the drop tank could use more conventional rocket engines rather than not-yet-developed hypersonic airbreathing engines.
