I've put together an RAR file of about 11 MB on ejectors for cooling, containing:

A NACA report on tests of a large family of ejectors driven by engine exhaust

Another NACA report providing guidance on how much an exhaust-gas nozzle can be necked down without incurring a back-pressure power loss.

An article on Convair's use of ejectors in commercial airliners to overcome cooling drag and ensure reliable cooling

Airesman's article in Alternative Engines, Volume 2

I just need someplace to post it.
