Investigation of a High-Performance Top Inlet to Mach Number of 2.0 and at Angles of Attack to 20 Degrees

Description: Memorandum presenting several top-inlet configurations tested on a body of revolution in the 8- by 6-foot supersonic wind tunnel at a range of angles of attack and free-stream Mach numbers. The effect on performance of the following variables were studied: throat bleed, ramp perforations, inlet approach surface, side fairings, fuselage fences, canopies, and a simulated 60 degree delta wing.

Investigation of the Influence of the Boundaries of a High-Speed Free Water Jet on the Planing Lift of a Flat Plate

Description: Memorandum presenting an investigation to determine the influence of the boundaries of a high-speed free water jet on the planing lift of a flat plate operating on the surface of the jet. No appreciable influence of speed on the planing lift coefficient for speeds from 50 to 200 feet per second was observed. Results also indicated that the parameters determining the jet size required for a given test condition have not been defined by these brief tests.

Some Examples of the Applications of the Transonic and Supersonic Area Rules to the Prediction of Wave Drag

Description: Report presenting a comparison of the experimental wave drags of bodies and wing-body combinations over a wide range of Mach numbers with the computed drags utilizing a 24-term Fourier series application of the supersonic area rule and results of equivalent-body tests. The equivalent-body technique was found to provide a good method for predicting the wave drag of certain wing-body combinations at and below a Mach number of 1, but becomes misleading at Mach numbers greater than 1.

Survey of microstructures and mechanical properties of over-temperatured S-816 turbine buckets from J47 engines

Description: Report presenting an extensive metallographic examination of a group of buckets overtemperatured in service. Most of the buckets showed an overaged microstructure. Results regarding the metallographic survey and stress-rupture tests are provided.
