Partly to gain experience of aero-elastic models constructed from Xylonite, and partly to provide information regarding loss of rolling power due to wing distortion, a tip-to-tip model of the wings of a Spitfire aircraft ...
An iterative method of solution is given for the problem of loss in rolling power due to wing deformation. The method is applicable at subsonic or supersonic speeds, and compressibility effects are allowed for, provided ...

Measurements and calculations of aileron effectiveness for an elastic model wing in low-speed flow are described. The experimental technique enabled rolling moments due to applied aileron and to rate of roll to be measured ...
An experimental investigation has been made to study the effect of casing wall boundary layers upon the rotating stall characteristics of an axial flow compressor in an isolated rotor row configuration. The boundary layer ...
The 4 x 3 ft Wind Tunnel was erected as a model of larger tunnels to investigate unconventional design features directed towards obtaining a high standard of flow. Diffusers of 5 deg cone angle are used, except for the ...
Estimates of atmospheric turbulence from counting accelerometer records show a large scatter. The simple assumption of a random distribution of gusts is inconsistent with this scatter. A formula which takes account of the ...
Section 1, some physical properties of an extruded cellular cellulose acetate. Section 2, the determination of poisson's ratio in compression of certain low density materials. Tensile, Compressive and Creep tests have been ...
A range of struts each consisting of 'Balsolite' filler sandwiched between two faces of one-sixteenth inch thick birch plywood has been tested in order to assess the efficiency of Balsolite as a stabilizer in sandwich ...
The purpose of the core in a sandwich structure is to stabilize the skins against local failure and to enable them to work together as a single beam, having a moment of section relatively much greater than that of the two ...
The fatigue test results, for elements and sections from the structures of aircraft, obtained by a number of experimenters are analysed in terms of the scatter present in the lives to fatigue failure. Data for structures ...
Schlieren tests on a series of conventionM turbine cascades have shown that the variations in performance at high speed can be accounted for by shock-wave and boundary-layer interaction. The rise in loss coefficient sometimes ...
