A calculation study of wing-aileron flutter in two degrees of freedom for two-dimensional supersonic flow
Report presenting the results of some sample calculations for the bending-aileron and torsion-aileron flutter of an idealized wing-aileron system for several values of Mach number in supersonic flow and some subsonic Mach numbers. The results are preliminary but may provide some knowledge of the influence of variations in certain parameters and to indicate some of the differences in the trends at high and low speeds.

Coefficient of friction and damage to contact area during the early stages of fretting 2: steel, iron, iron oxide, and glass combinations
Report presenting experiments to study the start of fretting and cause of damage during the early stages of fretting of steel-steel combinations at a frequency 5 cycles per minute, an amplitude of 0.006 inch, a load of 150 grams, in air with relative humidity of less than 10 percent. Pure iron, glass, and iron oxide powder compacts were used in supplementary experiments.

Combined Natural- and Forced-Convection Laminar Flow and Heat Transfer of Fluids With and Without Heat Sources in Channels With Linearly Varying Wall Temperatures
Note presenting an analysis of the flow of fluids with and without heat sources and subject to body forces between two plane parallel surfaces which are oriented in the direction of the generating body force under the condition that the temperature vary linearly along these surfaces. Results regarding the velocity and temperature distributions, heat transfer, and fluid flow are provided.

Comparison between theory and experiment for interference pressure field between wing and body at supersonic speeds
Report presenting pressure-distribution data for a wing-body combination at several Mach and Reynolds numbers to investigate the effects of wing-body interference. The model was a single-wedge, rectangular wing mounted on a cylindrical body with an ogival nose. Results regarding the general physical principles, effects of angle of attack, effect of wing-incidence angle, effect of Reynolds number, and comparison with theory from other sources are provided.

Effect of ignitor design and ignitor spark-gap environment on ignition in a turbojet combustor
Report presenting an investigation to determine the effect of ignitor design and ignitor spark-gap environment on the ignition-energy requirements of a single tubular turbojet engine combustor. Data were obtained for a range of altitude inlet-air pressures, two-air flow rates, a range of combustor-inlet air and fuel temperatures, and two fuels. The effects on ignition energy requirements of shielding the ignitor spark gap, fuel heating elements and auxiliary fuel fields, and gap width and ignitor spark-gap immersion depth were investigated.

An Experimental Investigation at Low Speeds of the Effects of Lip Shape on the Drag and Pressure Recovery of a Nose Inlet in a Body of Revolution
Report presenting wind-tunnel tests of a body of revolution with a circular nose inlet conducted at low speeds to ascertain some of the effects of inlet lip bluntness and profile on diffuser performance and body drag. Testing occurred at free-stream Mach numbers up to 0.330 with inlet flows from zero to choking and a steady 0 degree angle of attack and angle of yaw. Results regarding the internal-flow studies with the strut-mounted model and drag and surface-pressure studies with the sting-supported model are provided.

An experimental study of porosity characteristics of perforated materials in normal and parallel flow
Report presenting an experimental investigation to determine the porosity characteristics of perforated materials in normal and parallel flow. The results indicted that the porosity of material is governed principally by its open ratio, but that density has a slight effect.

An extension of the investigation of the effects of heat transfer on boundary-layer transition on a parabolic body of revolution (NACA RM-10) at a Mach number of 1.61
Report presenting an investigation of the effects of heat transfer on boundary-layer transition at higher Reynolds numbers, greater amounts of heating, and a more extensive study of the effects of surface irregularities than what was published in a previous report. Report presenting tests with a smooth model and tests with surface roughness and tunnel flow disturbance are provided.
