  • 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 ...
  • 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 ...
  • On the periodic effects experienced by the blades of a contra-rotating airscrew pair 
    Collar, A. R. (H. M. Stationery Office, 1941)
    The present paper discusses the effects on the performance of a contra-rotating airscrew pair of the oscillatory nature of the flow round the blades. The blade sections at a representative radius are developed into two ...
  • On the static thrust of contra-rotating airscrews 
    Collar, A. R. (H. M. Stationery Office, 1941)
    Under static conditions or at low rates of advance, the blades of a single airscrew are often stalled, except perhaps for the outer sections. At first sight, it would appear that the same conditions must apply to the blades ...
  • On the stressing of polygonal tubes with particular reference to the torsion of tapered tubes of trapezoidal section 
    H. L. Cox (H. M. Stationery Office, 1942)
    A general method for stressing polygonal tubes is described and applied to the torsion of parallel and tapered tubes of rectangular and trapezoidal section. It is assumed that the shape of the tube is maintained by a limited ...
  • An orifice method of producing a high velocity stream 
    Binnie, A.M. (H. M. Stationery Office, 1940)
    Earlier papers (Binnie 1938 and 1940) have dealt with the uniformity of the stream produced by a venturi flume and with the possibility of employing this device for testing model seaplane floats. If the velocity of the ...
