A Review of Curtiss-Wright Rotary Engine Developments with Respect to General Aviation Potential

Relevant Rotary Engine developments at Curtiss-Wright over the period 1958-1979 are reviewed. Applicable automotive engine developments, including Stratified Charge, flight test results and future projections are presented. The current 300 HP aircraft engine prototype development status is discussed relative to application of parallel direct injected unthrottled Stratified Charge technology gains which demonstrated automotive diesel engine fuel consumption levels, low emissions and multi-fuel operation in other Rotary engine models.
