JOURNAL OF PROPULSION AND POWER Vol. 19, No. 6, November–December 2003 Solid Rocket Enabling Technologies and Milestones in the United States Leonard H. Caveny Fort Washington, Maryland 20744 Robert L. Geisler Tehachapi, California 93561 Russell A. Ellis Saratoga, California 95070 and Thomas L. Moore Chemical Propulsion Information Agency, Columbia, Maryland 21044 Leonard H. Caveny retired from the Ballistic Missile Defense Organization (BMDO) in 1997 where he served as Director, Science and Technology Directorate. He received Mechanical Engineering B.S. and M.S. degrees from Georgia Tech and Ph.D. from Univ. of Alabama. He served in the US Navy 1956–1959 as Engineering Officer of a Destroyer. His solid rocket motor experience includes Thiokol’s Huntsville Division (1960s), Guggenheim Laboratories of Princeton University (1970s), Air Force Office of Scientific Research (AFOSR) in the (1980–1984), and Strategic Defense Initiative Organization and BMDO (1984–1997). He chairs the National Research Council (NRC) Panel to evaluate proposals on Advanced Propulsion Research for AFOSR. He serves on the NRC Committee for the Review of NASA’s Pioneering Revolutionary Technology Program. His present consulting includes solid rocket systems, energetic materials, and ignition. He authored over 50 refereed articles and received 11 U.S. patents. He is a Fellow of AIAA and recipient of the AIAA Wyld Propulsion Medal. Robert L. Geisler received a B.S. in Chemical Engineering from the University of Cincinnati in 1958. He worked in the solid rocket program at the Air Force Rocket Propulsion Laboratory (AFRPL) for 32 years through 1990. He was intimately involved in the ARPA Principia project after Sputnik and helped to establish and conduct the AFRPL in-house and contractual programs on solid propellants; hazards; surveillance, aging and mechanical behavior; plumes; combustion; nozzles; and performance prediction and measurement. He was a key figure in providing technology base and support programs for Minuteman, Peacekeeper and the Titan solid booster programs. He has experience in failure investigation work on major solid rocket systems; detonation hazards; aluminum combustion and related phenomena. He rose through the ranks from project engineer to director of the Vehicle Systems division where he directed the efforts on satellite technology; systems analysis; the National Hover Test Facility, Kinetic Kill Vehicles and Electric Propulsion. Now in his 45th year in solid rocketry he has worked on most aspects of solid rocket propulsion and serves as a private consultant for a number of organizations. He serves on the AIAA Solid Rockets History subcommittee. He is an AIAA Associate Fellow. Russell A. Ellis received a B.A. from Columbia College, Columbia University in 1958, a B.S. in Mechanical Engineering from the School of Engineering, Columbia University in 1962, and a Master’s Degree in Engineering Administration from the University of Utah in 1971. He served in the US Navy 1958–1961 as Engineering Officer of a Destroyer. In 1962 he began what is now a 41-yr career in the solid rocket industry. His first nine years were with Thiokol/Wasatch and the next 32 at Chemical Systems Division, Pratt and Whitney, San Jose, CA. He retired in 2003 and now is a Consultant to the industry. He is well known for his work in advanced nozzles and materials, particularly application of carbon–carbon ITEs and exit cones to nozzles. He authored the NASA nozzle design monograph and has presented and published over 50 technical papers associated with solid rockets. He serves on the AIAA Solid Rockets Technical Committee as a member of the Education subcommittee. He is an AIAA Fellow. Thomas L. Moore received a B.S. in Mechanical Engineering from West Virginia University in 1983 and an M.S. in Technical Management from The Johns Hopkins University in 2001. He spent the first ten years of his career at Hercules’ Allegany Ballistics Laboratory (ABL) in Rocket Center, West Virginia, where he held various assignments in tactical missile propulsion and launch eject gas generator development, production, and R&D programs. In 1993, Moore joined the Chemical Propulsion Information Agency (CPIA), a U.S. Department of Defense Information Analysis Center operated by The Johns Hopkins University, where he supervises CPIA’s technical services to the propulsion industry, and edits and maintains several national solid propulsion reference manuals and databases. He is currently the Deputy Director of CPIA. In 2001, he successfully nominated Allegany Ballistics Laboratory for recognition as a Historic Aerospace Site by the AIAA. Moore has authored several solid rocket history papers and wrote the annual Solid Rockets highlights for Aerospace America magazine from 2000 through 2003. He is an AIAA Senior Member and member of the Solid Rockets Technical Committee (SRTC). Received 7 August 2003; revision received 8 September 2003; accepted for publication 9 September 2003.
