Philip C. Pelfrey - President
Philip Pelfrey has been developing advanced propulsion systems for more than 30 years. He started his career in 1987 developing replacement turbopumps for the Space Shuttle Main Engine (SSME) as part of a NASA effort to increase overall launch system reliability following the Challenger accident. Those turbopumps demonstrated 120 mission cycle life in order to be certified for 55 launches. 30 years later, the SSME (now called the RS-25) will be used on NASA’s new Space Launch System (SLS) for deep space exploration (shown in the video on the Home page). Over his 30-year career, he has worked on virtually every rocket engine cycle and propellant combination, including developing new engine cycles and using novel propellants.
During this same period, he has helped to develop some of the most advanced commercial and military turbine engine technology including XTC/XTE-67, PW5000, F119 (powering the F-22 Raptor), F135 (powering the Joint Strike Fighter, JSF F-35 Lightning II), Trent, FTA-37F, and FTC/FTF-250C/F. His innovation has resulted in more than a dozen patents and 30 publications.
With physics-based design and analysis tools and a comprehensive, validated development process, he started P3 Technologies to offer affordable, state-of-the-art propulsion technology and services to the U.S. Government, its contractors, and commercial companies.
