After earning degrees in Physics and in Nuclear Engineering at MIT, Stephen Evans started work at Rocketdyne division of North American Aviation as a system engineer involved in design and mission studies of advanced maneuvering space vehicles. He was assigned as Rocketdyne’s member on the Joint Army, Navy, NASA, Air Force (JANNAF) Liquid Rocket Propulsion Performance Committee. He was a key contributor to developing the industry standard rocket engine performance methodology and authored the Chemical Propulsion Information Agency (CPIA) manuals that documented the methodology for use by government agencies and industry. He analyzed the performance of the J-2 and redesigned Lunar Module Ascent Engines for the Apollo program. He headed design configuration optimization studies for the Space Shuttle Main Engine during the initial design phase for that engine. While working at Rocketdyne he also earned an Executive degree in Engineering Management at UCLA. He was Program Manager for Space Station Propulsion Technology Development and Proposal Manager for the Space Station Electrical Power System. He represented Rocketdyne on the oversight committee for the NASA Propulsion Engineering Research Center at Pennsylvania State University, on the Space Technology Advancement Committee, on the Aerospace Industry Association’s Technology for the 90’s Committee, and presented the Rocketdyne position on propulsion for the Mars mission to Ton Stafford’s Human Exploration Initiative study group. As Director of Advanced Technology Programs (Chief Technology Officer) he managed the development of key advances in rocket engine design, development and manufacture that were incorporated into the RS-68 engine for the Delta IV launch vehicle.
