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 ...
The report gives an outline of the development of the principles on which potential problems in lifting plane theory are solved by the use of a vortex lattice for the purpose of computing downwash. The conditions of ...
Full-scale impact tests made on a Sunderland at the Marine Aircraft Experimental Establishment were in disagreement both with basic model tests and existing theories. The existing information on theoretical, model land ...
The application of second harmonic control on a helicopter rotor causes a redistribution of the loading over the disc. This can be utilised to postpone the forward speed limitations imposed by stalling of the retreating ...
The incompressible second-order theory for two-dimensional aerofoils is extended to finite swept wings. The flow field is represented by distributions of sources and 'lifting singularities' on the 'chord surface' which ...
The shear flow on the annular walls of axial-flow turbo-machines is generally the primary cause of the difficulties encountered in the improvement of the performance and reliability of these machines. It creates a flow of ...
