Supersonic and Transonic Aircraft Problems

Journal of the American Rocket Society, 1947
A great honor has been conferred on me, especially the invitation^which said that I was particularly qualified" to discuss supersonic and transonic aircraft problems. Throughout my ! disertation the emphasis is going to be placed entirely on that word 'problem'. As so ably put by General Craigie quite recently in that "with respect to many of the major

Noise generation in transonic tunnels

8th Aerodynamic Testing Conference, 1974
R emphasis has been placed on the noise environment in transonic facilities. This increased attention surrounding the tunnel noise problem was brought about by the advent of high lift configurations operating in the transonic regime. Experimental investigations' have shown that the tunnel noise environment may have a significant influence on high lift ...

The Transonic Free Flight Range

1953
Abstract : This report contains a current description of the Transonic Free Flight Range. This range, developed at the Ballistic Research Laboratories at Aberdeen Proving Ground for ballistic and aerodynamic research, has been in operation for approximately eight years.

Mathematical Problems in Transonic Flow

Canadian Mathematical Bulletin, 1986
AbstractWe present an outline of the problem of irrotational compressible flow past an airfoil at speeds that lie somewhere between those of the supersonic flight of the Concorde and the subsonic flight of commercial airlines. The problem is simplified and the important role of modifying the equations with physics terms is examined.

Higher approximations of the transonic expansion in problems of unsteady transonic flow

Journal of Applied Mathematics and Mechanics, 1997
Abstract Modifications of the equation of unsteady transonic flow are investigated, which avoid the drawbacks which arise when using the transonic approximation (the Lin-Reissner-Tsien equations) and other equations of unsteady transonic flow to describe transonic flows. Several problems concerning flows of this kind (the stability of transonic flows,

Notes on the Transonic Indicia! Method

AIAA Journal, 1978
The indicial method for calculating flutter derivatives for two-dimensional airfoils at transonic speeds is discussed, with particular attention given to the effect of a moving shock on the flow variables in the indicial method. An expression for the pressure coefficient is developed on the basis of an explicit treatment of the shock motion; the ...

Transonic Airfoil and Intake Calculations

1989
Two-dimensional, transonic, inviscid flows of perfect gases are computed about airfoils and air intakes. The numerical technique is an unsteady version of the λ-scheme with two-dimensional shock fitting. Several problems involving NACA 0012 and Korn airfoils and three different intake cases, using the same geometry, are solved and discussed.
