  • Experiments on rigid airship R.29 
    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 ...
  • 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 ...
  • Experiments on the measurements of transition position by chemical methods 
    J. H. Preston; N. E. Sweeting; F. H. Burstall (H. M. Stationery Office, 1945)
    The smoke filament technique for detecting transition points is limited to speeds below 180 ft./sec, for orthodox atmospheric tunnels with good lighting and viewing conditions. Also many tunnels are of the enclosed pressure ...
  • Flight tests of a falcon fitted with an irving flap 
    J. Cohen; H. P. Fraser (H. M. Stationery Office, 1938)
    It has been stated that flaps for landing a clean, heavily loaded aeroplane, should provide a range of settings over which the lift is constant but the drag variable within wide limits, with low operating forces. The Irving ...
  • 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 ...
  • Frequency "admittance" curves for coupled engine crankshaft (torsional) and contra-revolving propeller (flexural) vibrations 
    J. Morris (H. M. Stationery Office, 1943)
    In this report the "admittance" method, for dealing with coupled vibrations of engine crankshaft propeller systems, is adapted to cover the case of contra-revolving propellers. The treatment is quite general in that the ...
  • Full scale trials on Scion M.3 with a gouge flap 
    J. Cohen (H. M. Stationery Office, 1936)
    Under review
  • 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 ...
  • 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 ...
  • Galerkin's method in mechanics and differential equations 
    Duncan, W. J. (H. M. Stationery Office, 1937)
    The method to be described here is attributed to the Russian investigator V. G. Galerkin, whose original papers are inaccessible to the present writer. His knowledge of the method is derived from a description given in a ...
  • General investion into the characteristics of the c.30 autogiro 
    P. A. Hufton; A. E. Woodward; F. J. Bigg; J. A. Beavan (H. M. Stationery Office, 1939)
    The present report on the performance of a gyro plane contains the first really satisfactory set of full scale data to be obtained in this country, and affords a valuable means of checking a body of theoretical investigation ...
  • A general theory of the autogyro 
    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 ...
  • 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 ...
  • Graphical method of calculating performance of airscrew 
    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 ...
  • 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 ...
  • The initial buckling of slightly curved panels under combined shear and compression 
    D. M. A. Leggett (H. M. Stationery Office, 1943)
    The initial buckling of flat rectangular panels under combined shear and compression has been investigated theoretically in R. & M. 1965. This report extends the results given there to panels which are long and slightly ...
  • 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 ...
  • 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
  • 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 ...
