Summary:

The benefits of integrating the propulsion system design to take advantage of the flow field shed by one aircraft component on another was demonstrated during the recent development of two Garrett-powered high performance turboprop aircraft. Equivalent shaft horsepower (ESHP) increased approximately 11 percent and equivalent specific fuel consumption (ESFC) improved approximately five percent when components upstream of the engine were modified to enhance ram recovery and to supercharge the engine. The effect of supercharging resulted in a "ram recovery" greater than 1.0 at the cruise design point.The improvements were obtained by modifying the following propulsion system components:
