Lockheed's making noise about openly announcing their hypersonic scramjet engine. Should be amusing.
Define "Amusing" usage in above post please.
PIM recently passed a major flight readiness milestone with the successful completion of functional and environmental testing of its systems and software. The spacecraft is scheduled for launch in early 2017 and will demonstrate the practical capabilities of a hydroxyl ammonium nitrate based fuel/oxidizer propellant blend, known as AF-M315E, developed by the U.S. Air Force Research Laboratory at Edwards Air Force Base in California. The new propellant offers higher performance and is safer to handle and easier on the environment than traditional chemical fuels such as hydrazine currently used in spacecraft thrusters. It also requires fewer handling restrictions and has potentially shorter launch processing times, resulting in lowered costs.
More of the new propellant can be stored in propellant tanks of the same volume, resulting in a 50-percent increase in spacecraft maneuvering capability for a given volume. It also has a lower freezing point than hydrazine, requiring less spacecraft power to maintain the propellant temperature. These characteristics make it ideal for a wide range of emerging small, deep space satellite missions.
