Propulsion fundamentals
Turbo-fan, turbo-prop engine and helicopter turbine
This course deals with the numerous types of engines, the double-flow double-core turbofan principle and the technologies used depending on the engine parts.
The course lasts 1 day (7 hours).
This course is dedicated to engineers and technicians who want to know about not only the turbofan principle but also the technologies and devices used depending on the different engine sub-parts.
The speaker ensures an easy understanding of the various domains.
The slides are well illustrated.
Level: Basic
This course is dedicated to engineers and technicians.
