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.
