The present research programme of the National Physical Laboratory is concerned with the influence exerted on model forces and surface pressures by the thick, laminar boundary layers characteristic of rarefied, near-continuum ...

Tests have been made at a Mach number of 1.41 on six elliptic cones forming two families of models. In the first, the vertex angle in the plane of the major axes of the elliptic cross-sections was maintained constant at ...

This report contains an analysis of the surface-pressuie distributions on two aerofoil sections of 10% thickness/chord ratio, at Math numbers near 2 and 4, and at Reynolds numbers between 93 and 1920, based on model chord. ...

1. Summary and Introduction.--A series of tests has been made in the National Physical Laboratory 20-in. x 8-in. High Speed Wind Tunnel on a two-dimensional pressure-plotting aerofoil of five inches chord and RAE 104 ...
