Crack-line Green's functions are obtained for cracks in various twodimensional configurations. The boundary element method, coupled with a singular field model of the crack tip, has been used to solve the initial elasticity problem. The Green's functions can be used to obtain the stress intensity factors for cracks in arbitrary stress fields...

The complementary function of a binary aeroelastic system at the frequency coalescence airspeed is constructed using a matrix method. The method makes use of the adjoints and derived adjoints of the characteristic matrix. A subroutine, written in 1900 Fortran, for the numerica1 evaluation of these adjoints is described.

This report details the changes made to the design of a dc fuel pump motor in order to reduce the LF interference it produced, and compares the level of ripple voltage before and after these changes were made.

A flexible panel, set in an infinite wall, is subject to an excitation force distribution which can be described by a correlation function. The panel vibrates and radiates sound. Expressions are derived for the intensity and pressure power spectrum in the sound field at points which are far away from the panel in comparison with the superficial...

A method of obtaining numerical values of generalised airforces on a thin wing oscillating harmonically in subsonic flow is described. It is assumed that the linearised equations of potential flow are valid. The essence of the method is the approximate solution, by collocation, of the integral equation relating the loading distribution and...

Corrosion tests are described of two magnesium-silver - rare earth metals - zirconium alloys having different nominal rare earth metal contents. The susceptibility to corrosion of these alloys is compared with that of magnesium-zinc-zirconium alloy to DTD.721A. The degree of protection afforded to these alloys by various surface treatments has...

Approximate expressions for the generalised airforces acting on a rectangular wing of low aspect ratio oscillating harmonically in sonic flow at low frequencies are derived in this paper. The modes of oscillation considered are rigid modes and a small selection of flexible modes. Results are presented as the first few terms of infinite...

The lift distribution on a two-dimensional wing oscillating in accelerated flight is obtained by solving the linearised partial differential equation for the velocity potential in the gas flow about the wing and applying the linearised Bernoulli equation. Expressions for the total lift and moment are obtained as integrals involving the upwash on...

An account is given of methods used in supersonic wind tunnels for observation of boundary layer phenomena, in particular of the sublimation and oil film techniques. Examples are given of the uses of these techniques. On the fixing of transition a rough guide is given for the minimum size of wire required, with an example of the use of wires....

The variation with sweepback of the total drag of an aircraft in level flight at supersonic speeds is calculated. It is shown that sweepback is not uniformly beneficial but that in general the optimum amount of sweepback depends on the design speed and altitude. The College of Aeronautics was founded in 1946 and was granted university status in...
