On transonic flow past a wave-shaped wall
Author(s): Kaplan, Carl
Abstract: This report is an extension of a previous investigation (described in NACA rep. 1069) concerned with the solution of the nonlinear differential equation for transonic flow past a wavy wall. In the present work several new ...

A unified two-dimensional approach to the calculation of three-dimensional hypersonic flows, with application to bodies of revolution
Author(s): Eggers, A J , Jr; Savin, Raymond C
Abstract: A procedure for calculating three-dimensional steady and nonsteady supersonic flows with the method of characteristics is developed and discussed. An approximate method is deduced from the characteristics method and shown to ...

A biharmonic relaxation method for calculating thermal stress in cooled irregular cylinders
Author(s): Holms, Arthur G
Abstract: A numerical method was developed for calculating thermal stresses in irregular cylinders cooled by one or more internal passages. The use of relaxation methods and elementary methods of finite differences was found to give ...

Thin airfoil theory based on approximate solution of the transonic flow equation
Author(s): Spreiter, John R; Alksne, Alberta Y
Abstract: A method is presented for the approximate solution of the nonlinear equations of transonic flow theory. Solutions are found for two-dimensional flows at a Mach number of 1 and for purely subsonic and purely supersonic flows. ...

Unsteady oblique interaction of a shock wave with a plane disturbance
Author(s): Moore, Franklin K
Abstract: Analysis is made of the flow field produced by oblique impingement of weak plane disturbances of arbitrary profile on a plane normal shock. Three types of disturbance are considered: (a) sound wave propagating in the gas at ...

Bodies of revolution having minimum drag at high supersonic airspeeds
Author(s): Eggers, A J , Jr; Resnikoff, Meyer M; Dennis, David H
Abstract: Approximate shapes of nonlifting bodies having minimum pressure foredrag at high supersonic airspeeds are calculated. With the aid of Newton's law of resistance, the investigation is carried out for various combinations of ...
