Application of Transonic Similarity

Description: "From a review of the different similarity approaches to compressible potential flow, the meaning and limitations of transonic similarity are traced back to their origin. Although the main text deals with the quasi two-dimensional flow, special suggestions for the case of axisymmetric bodies are added in an appendix" (p. 1).

A Correlation by Means of the Transonic Similarity Rules of the Experimentally Determined Characteristics of 22 Rectangular Wings of Symmetrical Profile

Description: From Summary: "The transonic similarity rules have been applied to the correlation of experimental data for a series of 22 rectangular wings having symmetrical NACA 63A-series sections, aspect ratios from 1/2 to 6, and thicknesses from 2 to 10 percent. The data were obtained by use of the transonic bump technique over a Mach number range from 0.40 to 1.10, corresponding to a Reynolds number range from 1.25 to 2.05 million. The results show that it is possible to correlate experimental data throughout the subsonic, transonic, and moderate supersonic regimes by using the transonic similarity parameters in forms which are consistent with the Prandtl-Glauert rule of linearized theory."

A correlation of experimental zero-lift drag of rectangular wings with symmetrical NACA 65-series airfoil sections by means of the transonic similarity law for wings of finite aspect ratio

Description: Report presenting an application of the transonic similarity law to the correlation of the zero-lift drag of rectangular wings obtained by means of free-fall and rocket techniques. Results regarding the basic data, the modified similarity rule, correlation of data, and similarity law for swept wings are provided.

Theoretical investigation and application of transonic similarity law for two dimensional flow

Description: Report presenting an investigation of the use of the transonic similarity law for two-dimensional flow by an iteration procedure. The results indicated that potential can be expressed as a power series in a single parameter that depends on Mach number, thickness ratio, and ratio of specific heats.

Transonic similarity rules for lifting wings

Description: Report presenting the use of similarity rules for the transonic flow about lifting wings are derived by considering the change in the flow field due to angle of attack as a small perturbation to the nonlifting flow field. It has an advantage over other approaches because the effects of angle of attack and airfoil geometry are partially separated.

Theoretical study of the transonic lift of a double-wedge profile with detached bow wave

Description: Report presenting a theoretical study of the aerodynamic characteristics at small angle of attack of a thin, double-wedge profile in the range of supersonic flight speed in which the bow wave is detached. The calculations provide, for extremely small angles of attack, the following information as a function of the transonic similarity parameter: chordwise lift distribution, lift-curve slope, and position of center of lift.
