The Aerodynamic Design of Supersonic Propellers from Structural Considerations

Description: From Summary: "The aerodynamic design of propellers from considerations of centrifugal force is presented. By applying a constant minimum value of thickness ratio from root to tip and allowing the distribution of required area to appear in the blade plan form, propellers with good efficiency are realized at high Mach numbers by the method of this paper."

Corrections for Lift, Drag, and Moment of an Airfoil in a Supersonic Tunnel Having a Given Static Pressure Gradient

Description: Note presenting an analysis of the corrections for lift, drag, and moment of a two-dimensional airfoil as tested in the working section of a supersonic tunnel in which the pressure field, instead of being uniform, is characterized by gradients in the axial and transverse directions. The pressure gradients of the tunnel as well as the effect of the airfoil to be tested are regarded as perturbations of the original rectilinear flow field of given Mach number.

Effective lubrication range for steel surfaces boundary lubricated at high sliding velocities by various classes of synthetic fluids

Description: Report presenting an exploration of synthetic lubricants, which involved studying the effects of a wide range of sliding velocities on boundary lubrication. The data showed that a number of synthetics, including diesters, polyethers, a silicate ester, and a phosphonate ester as well as a silicone-diester blend are more effective boundary lubricants at high sliding velocities than comparable petroleum oils.

General Correlation of Temperature Profiles Downstream of a Heated Air Jet Directed at Various Angles to Air Stream

Description: An experimental investigation was conducted to determine the temperature profiles downstream of heated air jets directed at angles of 90 deg, 60 deg, 45 deg, and 30 deg to an air stream. The profiles were determined at two positions downstream of the jet as a function of jet diameter, jet density, jet velocity, free-stream density, free-stream velocity, jet total temperature, orifice flow coefficient, and jet angle. A method is presented which yields a good approximation of the temperature profile in terms of the flow and geometric conditions.

Influence of Nonmartensitic Transformation Products on Mechanical Properties of Tempered Martensite

Description: "The influence of nonmartensitic transformations products on the mechanical properties of tempered martensite is presented for samples of a SAE 4340 steel, partially isothermally transformed to specific high-temperature transformation products and quenched and tempered to hardness values of from 25 to 40 Rockwell C. The effects of upper bainite in amounts of 1,5, 10, 20 and 50 percent, of 5 percent ferrite, and of 5 percent pearlite on the tensile, impact, and fatigue properties are evaluated" (p. 1).

Interaction between a supersonic stream and a parallel subsonic stream bounded by fluid at rest

Description: "The complex problem of the interaction between shock waves and boundary layers in supersonic flow is not yet clearly understood, despite a number of theoretical studies. Among these, the analysis of Tsein and Finston is singled out here for further examination. In the Tsien-Finston model the boundary layer is simulated by a uniform subsonic stream of finite width bounded on one side by a solid wall and on the other side by the interface with a uniform supersonic stream of semi-infinite extent" (p. 2).

An Investigation Utilizing an Electrical Analogue of Cyclic Deicing of a Hollow Steel Propeller with an External Blade Shoe

Description: "A study has been made of the heat requirement for the cyclic de-icing of hollow steel propellers fitted with external blade heating shoes. Solutions to the equations for the heat flow in cyclic heating of propellers were obtained, using an electrical analogy. The study showed how the energy requirement for propeller de-icing with existing blade shoes could be decreased, and illustrated the effect of blade-shoe design on the energy requirement. It was demonstrated, for example, that by increasing the heating intensity and decreasing the heating period from those currently used the energy requirement could be decreased in the order of 60 percent" (p. 1).

Laminar Natural-Convection Flow and Heat Transfer of Fluids With and Without Heat Sources in Channels With Constant Wall Temperatures

Description: Note presenting an analysis of the natural-convection phenomenon, which shows that the flow and heat transfer, in general, are not only functions of the Prandtl and Grashof numbers but also depend on a new dimensionless parameter. If the parameter is not negligibly small, the compression work and frictional heating may appreciably affect this mode of heat transfer. Results regarding the velocity and temperature distributions and heat transfer are provided.

The Langley 2,000-horsepower propeller dynamometer and tests at high speed of an NACA 10-(3)(08)-03 two-blade propeller

Description: This paper contains a detailed description of a 2,000-horsepower propeller dynamometer used to make wind-tunnel tests of a two-blade NACA 10-(3)(08)-03 propeller for a range of blade angles from 20 degrees to 55 degrees at airspeeds up to 500 miles per hour. The results of these tests and comparisons with results obtained from a theoretical analysis and from previous tests made in other wind tunnels are presented.
