  • 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 ...
  • Prediction of undercarriage reactions 
    G. Temple (H. M. Stationery Office, 1944)
    The object of this report is to give a connected account of the methods which have been developed at the Royal Aircraft Establishment by Messrs. D. D. Lindsay, R. G. Thorne and S. A. Makovski for the prediction of undercarriage ...
  • 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 prevention of flutter of spring tabs 
    Collar, A. R. (H. M. Stationery Office, 1943)
    The present report gives a correlation of the results of earlier researches into the prevention of flutter of spring tabs. The restrictions on the way in which tab mass-balance must be applied, which are given in the earlier ...
  • 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 reaction on a wing whose angle of incidence is changing rapidly. wind tunnel experiments with a short period recording balance 
    W. S. Farren (H. M. Stationery Office, 1935)
    A balance has been developed in the Aeronautics Laboratory at Cambridge by which the reaction on a wing whose angle of incidence is increasing or decreasing rapidly can be recorded. The reactions have been measured on eight ...
  • The stability of a body towed by a light wire 
    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 ...
  • Stalling tests on a Blenheim 
    G. E. Pringle (H. M. Stationery Office, 1939)
    In extension of earlier flight tests it was required to investigate how accidental stalling and spinning of a Blenheim is affected by the setting of flaps, engine gills and throttles. The behaviour of the aircraft was ...
  • Tables for use in an improved method of airscrew strip theory calculation 
    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) ...
  • 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 ...
  • Theoretical relationships for an aerofoil with hinged flap 
    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.
