Lecture – Emerging Concepts in High Speed Air-Breathing Propulsion

Adam Dissel, Reaction Engines Inc


High speed air breathing propulsion is becoming more prevalent. The standard approaches involve turbojets, scramjets, and turbine based combined cycle systems. Emerging cycles include the Japanese ATREX engine (Air Turbo Ramjet Engine with eXpander cycle) and the air-breathing rocket engine, which rely on pre-cooling the air with heat exchangers. Additional emerging cycles include pressure gain cycles (Pulse Detonation Engines and Rotating Detonation Engines), Mass Injection Pre-Combustion Cooling (MIPCC), Oxy-Boost which injects oxygen during the cycle, and turbo-ramjets in which the air bypasses the turbojet at high speeds and the afterburner is treated as a ramjet. This course is designed to explore these cycles and bring a theoretical understanding of how to apply them and what performance advantages they might have.

Key Topics

Who Should Attend

The audience for this course is comprised of advanced aerospace conceptual designers and analysts interested in the application of hypersonic air-breathing to hypersonic cruise and access to space missions. These include but are not limited to aircraft designers, propulsion engineers, systems engineers, and aerodynamicists.

Dr. Adam Dissel, President, Reaction Engines Inc.
Adam leads the expansion of his company’s development efforts with the U.S. government and potential industry partners. Adam has over 15 years’ experience in the conceptual design of advanced hypersonic and launch vehicle systems with particular emphasis in the improvement of system affordability, responsiveness, and reusability.  Adam was previously System Architect for Responsive Space at Lockheed Martin Space Systems in Colorado. He holds a PhD and master’s degree in Aerospace Engineering from the University of Maryland and a bachelor’s degree in Mechanical Engineering from Utah State University.

Course Materials

Course notes will be made available about one week prior to the course event. You will receive an email with detailed instructions on how to access your course notes. Since these notes will not be distributed on site, AIAA and your course instructor highly recommend that you bring your computer with the course notes already downloaded.
