JASC Awarded Contract with Boeing for High-Pressure “Smart” Regulator for use Aboard the X-51A Research Vehicle
JASC has been awarded a contract to design and develop a novel pressure regulator for use in the X-51A Hypersonic Research Vehicle. This device will provide highly accurate pressure regulation to extremely tight tolerances (less than 1 psi) over the mission – despite the rapidly and widely changing pressure and temperatures at the inlet. This is accomplished via a single-stage in a very compact, lightweight package, through the use of active feedback and integral control electronics.
Initial units will be ready for ground testing of a flight engine in 3Q07, while flight hardware will be delivered during 1Q08.

Pratt & Whitney Rocketdyne’s Revolutionary Scramjet Engine Successfully Powers First X-51A Simulated Flight Engine using JASC High-Temperature Fuel Valves and JASC High-Pressure Start Control Valve
SJASC provided PWR with the high-temperature (up to 1400 ºF) fuel distribution valves that manage hot fuel delivery to various portions of the scramjet combustor, as well as help pre-condition the fuel.
JASC also supplied the high-pressure blow-down control valve that meters a gaseous hydrocarbon fuel to the engine to initiate combustion.
The valves used in the NASA tests are the penultimate versions of the actual flight hardware, and have proved that the technology employed in these units is successfully implemented and is ready for flight testing.
