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 ...

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. ...

Summary. A study has been made of the flow development over the wing as the incidence and stream Mach number vary and this is illustrated by surface pressure distributions and oil-flow patterns. The growth and movement of ...

Photographs have been taken of the flow round a 10 per cent thick RAE 104 aerofoil performing pitching oscillations at low values of the frequency parameter (ω < 0.1) in subsonic and supersonic air streams. Apart from a ...

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 ...
