Observations of turbulent-burst geometry and growth in supersonic flow

Description: Report presenting a study of the shape, growth, and formation rate of turbulent bursts in supersonic boundary layers using spark shadowgraphs of small gun-launched models in free flight through still air. The model shapes include cones, ogive-cylinders, and hollow cylinders aligned with the stream. Results regarding the burst thickness profiles, burst plan form and transverse growth, three-dimensional burst shape, burst upstream-edge velocity, burst longitudinal growth rate, burst downstream-edge velocity, burst formation rate, and observations from the shadowgraphs are provided.

Some new drag data on the NACA RM-10 missile and a correlation of the existing drag measurements at M = 1.6 and 3.0

Description: Report presenting the total zero-lift drag of a fin-stabilized parabolic body of revolution designated the RM-10 using scale models launched from a gun through still air at a range of Mach and Reynolds numbers. Results indicated that the location of transition had an important effect on the drag of the configuration.

The Ames supersonic free-flight wind tunnel

Description: From Introduction: "Because of the unusual nature of this equipment, and because it is proving to be very useful for certain kinds of aerodynamic research, this report has been prepared. It contains a description of the equipment and its use to obtain aerodynamic coefficients. The imperfections in the wind-tunnel air stream and their effect on model tests are also discussed."

Experimental investigation of the zero-lift drag of a fin-stabilized body of fineness ratio 10 at Mach numbers between 0.6 and 10

Description: Report presenting free-flight measurements of the zero-lift drag of a cruciform-finned body at a range of Mach and Reynolds numbers. Results regarding experimental total drag, comparison of theory with experiment, comparison of experiment with NOL results, boundary-layer transition, Reynolds number effects, and fin leading-edge shape are provided.

The Ames Supersonic Free-Flight Wind Tunnel

Description: Memorandum presenting a description of the Ames supersonic free-flight wind tunnel, which is a new piece of equipment for aerodynamic research at high supersonic Mach numbers. It has a wide Mach number range extending from low supersonic speeds to Mach numbers in excess of 10. The air stream in the tunnel is imperfect, mainly due to a symmetrical pair of oblique shock waves which reflect down the test section.
