Thanks for the link, Cathar! Unfortunately I had already found this site but am looking for a site that gives more detail about their theory of operation, main components, diagrams showing airflow paths etc. Despite an exhaustive internet search, I couldn't find anything suitable, which I found unusual with the wealth of aviation sites on-line.
Come on pilots and engineers! I know this gen. is out there- whether it be in web or book form, please give me some advice!
