A computer program in Extended Mercury Autocode (EMA) is described for the finite element analysis of plane stress problems in regions of arbitrary geometry, using constant strain triangular elements.
The fluid flow about planing plates and wedges is briefly described and discussed, and on the basis of theoretical and physical considerations of this flow empirical formulae are presented for the lift developed by these ...
Enthalpy charts have been constructed to facilitate dealing with the thermodynamic problems of combustion and flow of dissociating gases within the temperature range of 600 deg to 4,000 deg K. By means of a quantity called ...
By considering the entrainment properties of the turbulent boundary layer, a new and simple form of auxiliary equation has been derived for the calculation of the form parameter H. Comparison with experimental results shows ...
The theory of equilibrium of balloon flying cables is presented in a simplified form most suitable for applications, with numerical tables covering probably the full range of practical cases. A simplified derivation of ...
Two wings may be said to have equivalent pressure distributions if the distribution of Mn, the component of surface Mach number normal to the local isobars, is the same in both cases. A simple approximate method is given ...
Experimental values of the reduction in lift curve slope due to boundary layer on two-dimensional aerofoils in incompressible flow are compared with estimates derived from the Royal Aeronautical Society Data Sheet and ...

Summary. Section 1 gives some general concepts and definitions regarding heat transfer. In Section 2 a method is described for calculating the rates of heat transfer to the surface of an ideal flat plate or sharp cone in ...
Methods of predicting shock pressure recovery and external drag at all mass flows have been developed for conical centre-body intakes at supersonic speeds. Comparison with wind-tunnel measurements shows that the method for ...
The methods at present available for the estimation of the usual longitudinal and lateral stability derivatives of an airoraft are briefly discussed for each derivative in turn. This is preoeded by an introductory seotion ...
A practical procedure for the investigation of the state of stress around an arbitrary doubly-symmetric hole in infinite elastic sheets in tension and shear is presented. The associated problem of conformally mapping an ...
An optical method utilising a standard schlieren system is used to locate the position of the shock wave surrounding a conical body at a free stream Mach number of 4.0. An analysis of the conditions at the shock wave enable ...
Frequently turbines are tested in a laboratory with coot air which has thermodynamic properties different from those of the hot gas for which the turbine is designed. This note presents methods for correcting such tests ...
