- This online course provides an overview of a range of propulsion technologies
- All students will receive an AIAA Certificate of Completion at the end of the course.
OVERVIEW
The performance of any propulsion system designed for high speed or space applications is governed by the fundamental principles on which it is based. This course examines five classes of engines (both deployed and being developed) from the perspective of their underlying physical principles. The equations used to determine the thrust produced by airbreathing rockets, ram/scramjets, detonation wave engines, arcjets, and ion thrusters are developed highlighting relevant issues and approximations in their use. It also places these engines in the context of their range of relevance by relating the thrust generated to the thrust required for both to orbit and in orbit missions. This course is based on the book by the instructor:
J. Etele: Fundamentals of Transatmospheric and Space Propulsion (available on Amazon)

Professor Jason Etele has been teaching and researching aerospace propulsion at Carleton University (Canada) for twenty years and is the author of the book “Fundamentals of Transatmospheric and Space Propulsion”. He has been an invited lecturer for several AIAA Short Courses on High Speed Airbreathing Propulsion and an invited instructor on Space Systems and Propulsion at Tohoku University (Japan). He has also been an invited researcher at the Japan Aerospace Exploration Agency (JAXA) where he investigated airbreathing rocket concepts.
