  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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) ...
  • Lock, C. N. H.; Bateman, H.; Nixon, H. L. (H. M. Stationery Office, 1934-10)
    The main series of tests of the original family of airscrews described in R&M 829 consisted of measurements of overall thrust and torque on 5 two-bladed and four-bladed airscrews of pitch diameter ratios 0.3, 0.5, 0.7, 1.0 ...
  • Lock, C. N. H. (H. M. Stationery Office, 1934-10)
    A rapid method is described of making calculations of airscrew performance by means of charts. The first application is to ordinary strip theory calculations on the basis of the formulae of Ref. 5. Six charts are required ...
