Never heard of it being used in production aircraft. :-)
These particular nacelles I read about already had a cooling impeller just inside the inlet. Cold air drawn in, hot air forced out, generating some thrust already. Someone got the bright idea of adding avgas injectors and spark plugs downstream.
The arrangement actually produced a significant increase in thrust, but never caught on. (Yeah, imagine the passengers watching long plumes of flame jetting back from the engines on takeoff...)
