LOS ANGELES AIR FORCE BASE, El Segundo, Calif. – The Space and Missile Systems Center released the tenth and final award notice on Jan. 27 under the Booster Propulsion Technology Maturation Broad Agency Announcement (BAA) solicitation supporting technology maturation and risk reduction for rocket propulsion system development. The Air Force’s portfolio of investments through this BAA is in the focus areas of Material Manufacturing and Development, primarily focused on reducing the cost of future engines, and Advanced Technologies, primarily focused on advancing the state of the art for future engines. These acquisitions will mature booster propulsion technology and reduce risk for the U.S. domestic industry base.

Ten awards totaling approximately $34.6 million have been awarded under this BAA since Nov. 4, 2015.

The first award under this BAA was to Johns Hopkins University for Evaluation of “Additively Manufactured Liquid Rocket Engine Cooling Channels” for approximately $545,000 to improve performance in next-generation rocket engine thrust chambers and cooling channels.

The second award was to Tanner Research Inc. for “Solid Rocket Motor (SRM) Ignition System with Built-In Test (BiT)” for approximately $902,000 to develop an ignition system that can simplify detection of defective solid rocket motors.

The third award was to Johns Hopkins University for “Performance Sensitivity of Rocket Engine Cooling Channels” for approximately $935,000 to address industry knowledge gaps in propellant characteristics to enable LNG/Methane booster engine development.

The fourth award was to Moog Inc for “Non-Destructive Evaluation, Standards, and Testing” for approximately $728,000 to develop additive manufacturing technology for propellant control valves for use in a wide range of liquid engine systems.

The fifth award was to Orbital ATK for “Segmented Composite Case Advanced Technology” for approximately $3.13 million to focus on reducing weight of solid rocket motor case joints and improving reliability.

The sixth award was to Aerojet-Rocketdyne for “Additive Manufacturing Qualification Process for Reduced Booster Propulsion Life Cycle Cost” for approximately $6 million to develop a qualification process for additively manufactured engine parts that does not currently exist.

The seventh award was to Northrop Grumman for “Turbopump Assembly Additive Manufacturing” for approximately $5.47 million to improve technological readiness of an additively manufactured LOX/Methane booster engine TPA for insertion into a rocket propulsion system.

On Jan. 25, SMC released the eighth and ninth awards The eighth award was to Boeing for “Additively Manufactured High Pressure Engine Dome” for approximately $6.19 million to develop a full scale, complex, thick-walled engine component that advances additive manufacturing state of the art, and is targeted for integration into an engine development.

The ninth award was to Arctic Slope Technical Services for “A Low Cost, High Performance Preburner for Oxygen Rich Staged Combustion (ORSC)” for approximately $3.69 million to develop a preburner that implements a “continuous dilution” approach to minimize preburner exit thermal gradients to enhance system reliability and reduce life cycle cost.

On Jan. 27, SMC released the tenth and final award was to Northrop Grumman for “Duct-cooled, Carbon Silicon Carbide (C/SiC) Thrust Chamber Technology” for approximately $7.03 million to demonstrate both new manufacturing technology and a new nozzle cooling approach that will lead to a lighter combustion chamber design that is less expensive to produce. The targeted completion date of this effort is Jan. 26, 2018.

The BAA awards are part of a comprehensive Air Force plan to transition off the Russian made RD-180 propulsion system used on the Atlas V rocket by investing in industry launch solutions with the ultimate goal to competitively procure launch services in a robust domestic launch market.

“Many programs focus on risk reduction efforts too late to make a difference. By leading off this program with these awards, we have given industry tools to help ready themselves for developing launch systems, including the associated propulsion systems, that we will rely on to launch the nation’s satellites in the future,” said Lt. Gen. Samuel Greaves, the Air Force’s Program Executive Officer for Space and SMC commander. “This is essential in order to solidify U.S. assured access to space, transition the EELV program away from strategic foreign reliance, and support the U.S. launch industry’s commercial viability in the global market.”

Air Force Space Command’s Space and Missile Systems Center, located at Los Angeles Air Force Base, Calif., is the U.S. Air Force’s center of acquisition excellence for acquiring and developing military space systems. Its portfolio includes the Global Positioning System, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems and space situational awareness capabilities.
