ü This online course provides an overview of a range of propulsion technologies
ü 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: J.
Etele: Fundamentals of Transatmospheric and Space Propulsion (available on
Amazon).
- Examine and understand airbreathing, electrothermal, and electrostatic propulsion theory
- Contextualize various advanced propulsion concepts in their design space
- Broaden our understanding of the underlying physical principles relied on to generate thrust
- Understand the limitations and assumptions required to calculate thrust
- Understand the propulsion requirements of in orbit and launch missions
This course is aimed at early career professionals and graduate students in the aerospace sciences who want to broaden their understanding of advanced propulsion concepts and/or anyone with an interest in aerospace propulsion with a background in engineering.
CERTIFICATE: Receive an AIAA Course Completion Certificate upon viewing all course recordings. Please contact Lisa Le for a certificate.

Prof. Jason Etele has been teaching and researching aerospace propulsion at Carleton University (Canada) for over a decade and a half 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, an invited instructor on Space Systems and Propulsion at Tohoku University (Japan), and a visiting professor at Clarkson University. He has also been an invited researcher atthe Japan Aerospace Exploration Agency (JAXA) where he investigated airbreathing rocket concepts.
