Emerging Concepts in High Speed Air-Breathing Propulsion

7-8 July 2018
0800-1700 hrs

Synopsis

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 an understanding of how to apply them and what performance advantages they might have.

Key Topics

  • High Speed Air-Breathing Propulsion basics
  • Overview of multiple combined cycle propulsion systems
  • Overview of analysis techniques used in High Speed Air-Breathing Propulsion

Course Instructor

Tom Smithis a conceptual aircraft designer specializing in hypersonic airbreathing aircraft and spaceplanes. He designed the X-40, X-37A and X-37B spaceplanes. He has innovated concepts in the area of inward turning inlets for scramjet propulsion. He has broad skills in aerodynamics, structural design, propulsion integration, and multidisciplinary optimization.

Dr. Kevin Bowcutt is an industry leader in hypersonics at The Boeing Company. He is the father of the modern waverider. He has led the development of the multidisciplinary optimization capability at Boeing. His innovation and leadership has spanned the NASP program, the X-51 program, the HIFiRE consortium and many other programs.

Dr. Daniel E. Paxson is an aerospace research engineer with NASA Glenn Research Center, Research and Engineering Directorate. He earned his B.E. degree in mechanical engineering from Vanderbilt University and his M.S. and Ph.D. degrees at Rensselaer Polytechnic Institute. Since graduation, Dan has been at NASA conducting both experimental and analytical research in the areas of unsteady fluid mechanics, and gas dynamic propulsion and power systems. While there he has developed simulation, design, and optimization software, and designed or aided the design and operation of experimental rigs for wave rotor technology, active combustion instability control, high speed fuel valve systems, pulsed ejectors, pulsed (pressure-gain) combustors, pulse detonation engines, and rotating detonation engines. His simulation software has been used extensively by government, industry, and academic research groups. He has published more than 80 peer-reviewed papers, of which 20 are in journals. Dan is an AIAA Associate Fellow. He serves on the AIAA High Speed Air Breathing Propulsion Technical Committee, and is chair of the AIAA Pressure Gain Combustion Program Committee. He is also a member of the JANNAF Pressure Gain Combustion Working Group, and has served as a subject matter expert for DARPA, DOE, and the Air Force.

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 course 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 to the course.
