An engine driven propulsion fan. The preferred use of this fan is to power aircraft. Two turbochargers are provided both driven in series by exhaust gasses from a rotary engine. A portion of the compressed air produced by the second turbocharger provides thrust for the engine and a portion is used for engine air, further compressed by the first turbocharger.
