    Fage, A. (H. M. Stationery Office, 1930)
    The paper gives the results of experiments made recently to measure the drag of a circular cylinder of large diameter (23 in.). The more important measurements made in this country and abroad of the drags of circular ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Effect of discs on the air forces on a rotating cylinder 
    Thom, A. (H. M. Stationery Office, 1934)
    The Potential Flow streamlines past a circular cylinder are as shown in Fig. la ... If a circulation is superimposed the streamlines become as in Fig. lb ... As the circulation is increased the stagnation points move ...
  • 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) ...
  • Wind tunnel tests of high pitch airscrews 
    Lock, C. N. H.; Bateman, H.; Nixon, H. L. (H. M. Stationery Office, 1934-10)
    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 ...
  • 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 ...
  • Cooling of aircraft engines with special reference to ethylene glycol radiators enclosed in ducts 
    Meredith, F. W. (H. M. Stationery Office, 1935)
    The recent increase in the speed of aeroplanes has brought the question of cooling drag into prominence and forced the application of the principle of low velocity cooling. An analysis of the performance of a cooling system ...
  • 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 ...
  • Full scale trials on Scion M.3 with a gouge flap 
    J. Cohen (H. M. Stationery Office, 1936)
    Under review
  • The effect of blade twist on the characteristics of the c.30 autogiro 
    J. A. Beavan; Lock, C. N. H. (H. M. Stationery Office, 1936)
    An analysis of the blade motion and force characteristics of the standard Cierva C.30 autogiro rotor is made, taking into account the torsional flexibility of the blades. The results are applied to the steady motion and ...
  • 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 ...
  • The calculation of the profile drag of aerofoils 
    H. B. Squire; A. D. Young (H. M. Stationery Office, 1937)
    Owing to improvements in aerodynamic design it is desirable to be able to predict profile drag accurately. A method of calculating the profile drag of aerofoils is developed and is applied to investigate the drag of a flat ...
  • 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 ...
