NASA Astronaut Visits JASC
On Tuesday, November 8 NASA astronaut Megan McArthur visited JASC in conjunction with our work on the CST-100 Starliner space capsule system. She gave an informative presentation on her career as an astronaut and the future on human spaceflight.
McArthur holds an aerospace engineering degree from UCLA and a Ph.D. in oceanography from UC-San Diego. She was selected as an astronaut in 2000 and in 2009 served as a mission specialist aboard Space Shuttle Atlantis on STS-125, the final repair mission to the Hubble Telescope. Currently, she provides support to crews in training and those aboard the International Space Station as deputy chief of the astronaut office ISS Operations Branch.
JASC is proud to be partnered with Aerojet-Rocketdyne (AR) in supplying critical valves to support the CST-100 Crew Capsule Service Module (CCSM) program. JASC is supplying the main valves found in the Service Module Pressure Panel. This panel takes stored high-pressure helium gas and regulates the pressure to the fuel and oxidizer tanks. JASC valves are used in all three propulsion subsystems: the Reaction Control thrusters (RCS), the Orbital Maneuvering and Control system (OMAC) and the Launch Abort Engines (LAE).
JASC looks forward to supporting the CST-100 program on many future flights. Located in Tempe, AZ, JASC is an engineering solutions provider for the aerospace, space, and gas turbine industries.
New Shepard Space Vehicle Makes Fifth Flight
JASC congratulates Blue Origin on the fifth flight of its re-useable New Shepard space vehicle on Wednesday, October 5. The in-flight test of the capsule abort system successfully separated the capsule from the booster. The capsule descended under parachutes to a landing in the west Texas desert. The booster survived the separation and continued on under power to an apogee of 307,458 feet and then returned for a vertical landing at the launch site.
JASC designed and manufactured the Flight Control System Actuators and the engine Thrust Vector Control Actuators used on New Shepard. Both of these actuators are servo-hydraulic units, with the former used to steer the vehicle and provide aerodynamic stability, and the latter to vector the engine/nozzle for the same purpose.
JASC looks forward to supporting Blue Origin’s actuator needs on many future successful flights. Located in Tempe, AZ, JASC is an engineering solutions provider for the aerospace, space, and gas turbine industries.
Increase Reliability and Performance with New JASC Products
It’s So Cool
All New Water-Cooled 3-Way Purge Valve
The JASC Water-Cooled Three-Way Purge Valve was engineered to prevent liquid fuel coking that typically occurs when valves are exposed to heat for extended periods of time while the turbine is operating on gas fuel.
JASC’s new and improved Water-Cooled Three-Way Purge Valve features extensive internal cooling paths to keep critical components below the liquid fuel coking threshold. All-stainless steel construction provides increased corrosion resistance.
JASC’s Three-Way Purge Valves are designed to have a long operating life and can be refurbished, resulting in a lower total cost of ownership.
Cool Your Pipes
Reduces Risk of Coking in Idle Liquid Fuel Lines Near Combustor Cans
The JASC Heatsink Clamp is designed to move heat away from liquid fuel lines by utilizing the adjacent coolant lines while the turbine is running on gaseous fuel.
With liquid fuel flow checked in close proximity to the combustor cans during operation on gaseous fuel, the liquid fuel can slowly cook down to sludge or worse yet form carbon deposits, aka coke, on vital components of the liquid fuel system. When liquid fuel is needed, the sludge or carbon is introduced into the valves and combustion nozzles affecting turbine performance. Now you can put the coolant lines to even better use.
JASC System-Specific Products
For Increased Reliability and Performance
Provides reliable valve function so that seamless fuel transfers from gas to liquid fuel can be achieved.
Check valve failures, flow divider failures, fuel system evacuation, exhaust temperature spreads and other backup liquid fuel system related turbine trips can be resolved with a variety of our patented designs.
JASC’s New Heatsink Clamp Reduces Risk of Coking in Idle Liquid Fuel Lines Near Combustor Cans
CFD analysis shows how effective active cooling can be. This example demonstrates the results when the coolant temperature is 120°F and the test oven set for 550°F. All temperatures in the simulated liquid fuel line are well below the coking temperature.

the combustion nozzles, if anything flows at all.
If you have already taken advantage of JASC’s Water-Cooled technology you know about the benefits of eliminating coking with our Three Way Purge Valves and Liquid Fuel Check Valves. Now you can put the coolant lines to even better use.

In Design! An All-New Design for JASC’s Water Cooled Three-Way Purge Valve
The JASC Water Cooled Three-Way Purge Valve was engineered to prevent liquid fuel coking that typically occurs when valves are exposed to heat for extended periods of time while the turbine is operating on gas fuel.
JASC’s new and improved Water Cooled Three-Way Purge Valve features internal cooling paths in the housing, spool and flange to keep critical components below the liquid fuel coking threshold. All-stainless steel construction provides increased corrosion resistance.
Like the original Three-Way Purge Valve, JASC’s new Water Cooled Three-Way Purge Valve is a spool valve. This configuration combines purge air and fuel flow in a single package. The valve has a large fuel flow passage resulting in low pressure drops for high efficiency and the ability to pass large particulate contamination.
JASC designed seals specifically for this application—one in which the valve may have to sit dormant for up to a year without leakage and then switch immediately to flow liquid fuel. A special polymer was developed that is contamination tolerant and maintains its ANSI Class 6 sealing capability.
JASC’s Three-Way Purge Valves are designed to have a long operating life and can be refurbished, resulting in a lower total cost of ownership.
