    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 ...
  • A generalised type of Jankowski aerofoil 
    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 ...
  • 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 interference on the characteristics of an aerofoil in a wind tunnel of rectangular section 
    Glauert, H. (H. M. Stationery Office, 20/02/1932)
    Approximate formulae for the interference on an aerofoil in a rectangular wind tunnel have been known and used for several years. More accurate formulae have been developed by Terazawa and Rosenhead, but their results are ...
  • 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 ...
  • 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
  • Preliminary experiments on non-rigid airship "S.S.E.3 100,000," with a consideration of the performance data of various types of S.S. Airship 
    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, ...
  • The theory of the design of aerofoils with an analysis of the experimental results for the aerofoils R.A.F. 25, 26, 30 to 33 
    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. ...
  • On the conditions at the boundary of a fluid in turbulent motion 
    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 ...
  • Aerodynamic properties of a hemispherical cup with application to the hemispherical cup, windmill and anemometer 
    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 ...
  • 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 ...
  • A theory of thin aerofoils 
    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 ...
  • Vibrations of rafwires 
    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 ...
  • Account of some experiments on rigid airship r.26 
    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 ...
  • Propellors in high-speed dives 
    J. F. C. Conn; Love, E.M. (H. M. Stationery Office, 1942)
    The performance of a variable-pitch, 3-bladed propellor has been calculated for conditions of fixed power absorption, fixed rotational speed and varying advance speed. Curves of efficiency and power-loss ratios are given ...
  • The effect of variation of gear ratio on the performance of a variable-pitch airscrew for a high-speed aeroplane 
    R. C. Pankhurst; J. F. C. Conn; R. G. Fowler; Love, E.M. (H. M. Stationery Office, 1941)
    The effect of change of gear ratio has been examined in the case of a four-bladed airscrew of 14 ft. diameter absorbing 2,000 b.h.p. at 37,000 ft. at a forward speed of 450 m.p.h. with a given engine speed (3,700 r.p.m.). ...
