Abstract:

The report represents the results of a minimum preliminary design and analysis to determine the feasibility of achieving improved mixing efficiency with area ratios A2 to A0 near 27 for the multichannel ejector thrust augmentation concept. This is to be accomplished by replacing the existing cylindrical air supply ducts presently being used on an existing four channel ejector wing model in Building 71B, G Bay, at WPAFB, Dayton, Ohio, with oval or rectangular ducts incorporating an improved ejector nozzle design. This design study has been based on the use of the present Lycoming PLF1A-2 engine and includes investigations into the feasibility of eliminating the bleed air from the plenum and its effects in regard to engine performance.
