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.

Switching from Gas to Distillate Problem-Free
Over the years, many users purchased gas turbines (GTs) with dual-fuel capability to maximize availability—or so they thought. Most of those machines were designed to operate either on natural gas or distillate oil, thereby providing owner/operators some measure of protection against fuel supply disruptions and price volatility. However, users often found the operation of dual-fuel systems problematic and many either decommissioned or removed their liquid fuel systems altogether.
Those who have retained the capability to burn oil on an intermittent basis typically are dealing with annual refurbishment or replacement of OEM- supplied liquid-fuel check valves and flow dividers, according to Schuyler McElrath (smcelr8176@aol.com), a specialist in GT auxiliaries with more than a quarter century of experience troubleshooting fuel-system problems on frame engines for a major OEM.
Big Jet has Parts Made in the East Valley
The world’s largest passenger airliner may be assembled in Europe, but its connections reach all the way to the East Valley.
Two Tempe aerospace companies are making parts for the superjumbo Airbus A380, which is made its United States debut Monday in Los Angeles and New York.
JASC Continues Excellence in Quality System Management
The JASC Corporation continues its tradition of excellence in quality system management as evidenced by the recently completed ISO 9000:2000 and AS9100 reassessment audit in March 2007. The scores since registration have consistently been in the 95 percentile, each year showing continual quality system improvement. Once again, portions of the system were deemed “best in class” by the auditor, particularly the system of Internal Process Auditing.
“Our people have really embraced the system,” says JASC president and CEO, Harv Jansen. “They are beginning to come forth with suggestions that have far reaching improvements for the entire system, and it is beginning to pay dividends with increased business opportunities.” The successful implementation and improvement of the quality system has opened up many opportunities domestically and abroad. As JASC begins to break into these markets, ISO and AS9100 are key requirements. In the overwhelming majority of the cases, evidence of ISO certification relieves the need for the additional scrutiny of completing questionnaires and onsite audits, saving the company precious time and energy.
