  • On the flow of air behind an inclined flat plate of infinite span 
    Fage, A.; F. C. Johansen (H. M. Stationery Office, 1927)
    The general form of the flow behind an infinitely long thin flat plate inclined at a large angle to a fluid stream of infinite extent has been known for many years past. The essential features of the motion are illustrated ...
  • Further development of autogyro theory. parts 1 and 2 
    Lock, C. N. H. (H. M. Stationery Office, 1927)
    The general theory of the autogyro given by Glauert in R. & M. 1111 is based on certain simplifying approximations and assumptions. The object of the present paper is to develop the theory still further by removing some ...
  • The theoretical relationships for an aerofoil with a multiply hinged flap system 
    W. G. A. Perring (H. M. Stationery Office, 1928)
    Theoretical expressions for the lift and pitching moment of an aerofoil in two dimensional motion were developed in R&M 910. This theory was extended in R&M 1095 to include the hinge moment of a flap in the case of a ...
  • The boundary layer of the front portion of a cylinder 
    Thom, A. (H. M. Stationery Office, 1928)
    A large amount of information is now available regarding the flow of water or air past a cylinder placed across the stream so far as the behaviour of the main body of the fluid is concerned; but the conditions in the layer ...
  • An investigation of fluid flow in two dimensions 
    Thom, A. (H. M. Stationery Office, 1928)
    There are in existence several methods of obtaining numerical solutions to the two-dimensional flow of a perfect fluid for given boundary conditions
  • Wind tunnel experiments on a model autogyro at small angles of incidence 
    Lock, C. N. H.; Townend, H. C. H. (H. M. Stationery Office, 1928)
    A wooden scale model, 6 feet in diameter, of the original 4-bladed rotating wing unit of the Cierva Autogyro, has been tested in the Duplex tunnel at blade angles of 0°, 1°, 1.8°, 2.30° and 3°. It has also been tested as ...
  • The effects of turbulence and surface roughness on the drag of a cylinder 
    Fage, A.; J. H. Warsap (H. M. Stationery Office, 1929)
    Experiments have been made on that type of flow around a circular cylinder which is peculiarly sensitive to changes in Reynolds' number and for which the drag coefficient falls from 0.6 to 0.2 approximately. A study has ...
  • The elasticity of pintsch crystals of tungsten 
    S. J. Wright (H. M. Stationery Office, 1929)
    Very little work has hitherto been done on the Elastic Properties of Single Crystals of Metals. In the case of Tungsten, which is the only cubic crystal whose elastic constants have been determined, the previous work of ...
  • The interference of a wind tunnel on a symmetrical body 
    Lock, C. N. H. (H. M. Stationery Office, 1929-10)
    The effect of the boundaries of a wind tunnel on the flow in the neighbourhood of a symmetrical body (i.e. (a) in two dimensions, a cylinder having a plane of symmetry parallel to the axis of the tunnel : (b) in three ...
  • The application of Goldstein's theory to the practical design of airscrews 
    Lock, C. N. H. (H. M. Stationery Office, 1930)
    A recent paper on the Vortex theory of screw propellers, by Dr. S. Goldstein in the Proceedings of the Royal Society, contains a solution of the problem of the potential flow past a body consisting of a finite number of ...
  • The stability of a body towed by a light wire 
    Glauert, H. (H. M. Stationery Office, 1930)
    Summary.-Introductory (Purpose of Investigation.)-Owing to the practice of towing instruments belovv an aeroplane, the conditions for the stability of a towed body required investigation. Range of investigation.-The ...
  • The drag of circular cylinders and spheres at high values of reynolds number 
    Fage, A. (H. M. Stationery Office, 1930)
    The paper gives the results of experiments made recently to measure the drag of a circular cylinder of large diameter (23 in.). The more important measurements made in this country and abroad of the drags of circular ...
  • Further experiments on the flow around a circular cylinder 
    Fage, A.; Falkner, V. M. (H. M. Stationery Office, 1931)
    The intensity of friction on the surfaces of two cylinders of diameter 2·93 in. and 5·89 in. respectively have been determined from measurements of velocity taken at distances of about 0·0025 in. from the surface with small ...
  • Experiments on the flow past a rotating cylinder 
    Thom, A. (H. M. Stationery Office, 1931)
    Parts 1 -3. In 1925 the writer made a series of measurements of the direction and velocity of the air throughout the field about a rotating cylinder. The resulting velocity contours and streamlines were published at the ...
  • The flutter of monoplanes, biplanes and tail units 
    R. A. Frazer; W. J. Duncan (H. M. Stationery Office, 1931)
    The present report is the second in the Monograph series of the Aeronautical Research Committee to be devoted to the subject of flutter. The first, R. & M. 1155, appeared in 1928 and was entitled "The Flutter of Aeroplane ...
  • Heavy flexible cable for towing a heavy body below an aeroplane 
    Glauert, H. (H. M. Stationery Office, 1934)
    The mathematical expressions for the form of a heavy cable in a wind have been known for many years, but no systematic numerical results are available. Calculations have been made to derive a family of curves, depending ...
  • Effect of discs on the air forces on a rotating cylinder 
    Thom, A. (H. M. Stationery Office, 1934)
    The Potential Flow streamlines past a circular cylinder are as shown in Fig. la ... If a circulation is superimposed the streamlines become as in Fig. lb ... As the circulation is increased the stagnation points move ...
  • Tables for use in an improved method of airscrew strip theory calculation 
    Lock, C. N. H.; D. Yeatman (H. M. Stationery Office, 1934)
    An improved method of calculating the performance of an airscrew has been described in prcv:ious reports (Refs. I and 2), which includes an allowance for tip loss. The present report contains tables of a parameter (x) ...
