  • F. B. Bradfield (H. M. Stationery Office, 1919)
    Windmills of the hemispherical cup anemometer type have been used on aeroplanes for driving auxiliary apparatus, and it therefore appeared desirable to be able to calculate their performance. To do this it was necessary ...
  • Pannell, J. R. (H. M. Stationery Office, 1920)
    The experiments were carried out during a visit to Pulham Air Station when the trials of R.39. were temporarily interrupted. Other reports dealing with full-scale airship experiments are R. & M. 537, R. & M. 674, R. & M, ...
  • Pannell, J. R.; R. A. Frazer (H. M. Stationery Office, 1920)
    The Report gives experimental results obtained on four flights on R.26 during the period November, 1918-January, 1919. The following earlier Reports are quoted in the text :- R. & M. 668 (Airship R.33) ; R. & M. 537 and ...
  • T. E. Stanton; Marshall, Dorothy; C. N. Bryant (H. M. Stationery Office, 1920)
    The object of the experiments was to determine the nature of the flow in the neighbourhood of the boundary of a fluid flowing in turbulent motion through a channel with parallel walls. The observations were made on air ...
  • Pannell, J. R.; Bell, A. H. (H. M. Stationery Office, 1920)
    Airship R.29. was the last ship of the 27 Class and it was considered desirable that a record of her performance should be obtained before she was placed out of commission. Arrangements were, therefore, made for the ...
  • Harris, R. G. (H. M. Stationery Office, 1921)
    This report describes experimental and theoretical investigations of the vibrations of rafwires during "singing." The experimental work was confined to the laboratory. Observations were made on a rafwire in a wind channel ...
  • Glauert, H. (H. M. Stationery Office, 1924)
    Recently a number of aerofoils have been designed with the object of obtaining (1) a good thick wing, and (2) a racing wing. Experimental results for these aerofoils are contained in reports R.&M. 915, R.&M. 928, and R.&M. ...
  • Glauert, H. (H. M. Stationery Office, 1924)
    The present report develops a theory of thin aerofoils in two dimensional motion and simple integral expressions are obtained for the angle of incidence and moment coefficient at zero lift. A graphical method of integration ...
  • Glauert, H. (H. M. Stationery Office, 1924-01)
    The present report gives a short account of a generalised type of Jankowski aerofoil which avoids the difficulty of extreme thinness near the trailing edge associated with the ordinary Jankowski aerofoils. Calculations ...
  • Glauert, H. (H. M. Stationery Office, 1926)
    An autogyro obtains remarkably high lift forces from a system of freely rotating blades and it is important to develop a theory which will explain the behaviour of an autogyro and will provide a method of estimating the ...
  • Glauert, H. (H. M. Stationery Office, 1927)
    The use of an aerofoil with a hinged flap is of very general importance both for control surfaces and for main supporting surfaces, and in particular information is required as to the effect of varying the size of the flap.
  • 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 ...
