Effects of leading-edge devices and trailing-edge flaps on longitudinal characteristics of two 47.7 degree sweptback wings of aspect ratios 5.1 and 6.0 at a Reynolds number of 6.0 x 10(exp 6)
Report presenting an investigation in the 19-foot pressure tunnel to determine the effects of leading-edge stall-control devices and trailing-edge flaps on the longitudinal stability characteristics of a 47.7 degree sweptback wing that could have aspect ratios of 5.1 and 6.0 by using interchangeable wing tips. The effects of wing fences, roughness, and a fuselage were also determined. Results regarding the lift characteristics and lift-drag ratios are also provided.

Pressure-Rise and Leakage-Loss Characteristics of a Rotating Cowling
Report discussing an experimental and analytical investigation in order to study the pressure-rise and leakage-loss characteristics of rotating cowlings. A comparison of the theoretical and experimental results indicated that pressure-rise characteristics can be predicted if internal-flow losses and internal-flow angle at the cowling-vane trailing edge are known.
