  • A note on the behind armour effects from perforated alumina/aluminium targets 
    Hazell, P. J.; Fellows, N. A.; Hetherington, John G. (Elsevier Science B.V., Amsterdam., 1998-12-31)
    A thin, ceramic-faced armour, separated from a thick metal block, has been subjected to high-velocity impact by a 6.35 mm diameter steel sphere. Experimental work was carried out which compared firings into ceramic-fac ...
  • A note on the decay of aircraft trailing vortices 
    Lilley, G. M. (College of Aeronautics, 1964-03)
    An elementary theory of aircraft trailing vortex decay is presented based on an assumed law for the variation of the mean eddy viscosity with distance from the wing. This law is based on the experimental data of Rose ...
  • Note on the development of a trailing-edge flap as a stall-detector 
    Bethwaite, C. F. (College of Aeronautics, Cranfield, 1953-09)
    A trailing-edge flap protruding slightly outside the wing profile has been developed as a stall detector and flight trials on “Anson” and “Provost” aircraft have proved successful. The device gave an adequate stall warning ...
  • A note on the discontinuity stresses at the junction of a pressurised spherical shell and a cylinder 
    Houghton, D. S.; Chan, A. S. L. (College of Aeronautics, 1958-01)
    An analysis has been made of the forces and moments occurring at the junction of a pressurised spherical shell with an intersecting cylinder. The additional effects of having a temperature gradient along the length of ...
  • Note on the dynamics of a slightly deformable body 
    Hemp, W. S. (College of Aeronautics, Cranfield, 1947-02)
    The purpose of this note is to develop the equations of motion of a slightly deformable body. Appeal to general principles shows the independence of the translation (Para.2). Moving axis are defined in papa.3 which can be ...
  • Note on the efficiency of adiabatic shock 
    Morley, A. W. (College of Aeronautics, Cranfield., 1948-09)
    This note records some calculations of the efficiency of adiabatic shock in air (x=1.4); where the efficiency is defined as the ratio of the work used to compress the air in the shock wave, from the inlet static to the ...
  • A note on the estimation of some low speed characteristics of delta wings 
    Rose, R. G. (College of Aeronautics, Cranfield, 1953-01)
    The results of the Weissinger swept lifting line theory have been compared with other methods and experimental results. On the basis of this comparison empirical corrections to the Weissinger theory results have in some ...
  • Note on the limits to the local Mach number on an aerofoil in subsonic flow 
    Young, A. D. (College of Aeronautics, 1948-04)
    It has been noted in some experiments that the local Mach number just ahead of a shock wave on an aerofoil in subsonic flow is limited, values of the limit of the order of 1.4 are usually quoted. This note presents two ...
  • Note on the limits to the local Mach number on an aerofoil in subsonic flow 
    Young, A. D. (College of Aeronautics, 1948-10)
  • A note on the machinability of ultra high tensile steel 
    Purcell, J. (College of Aeronautics, 1957-01)
    The requirements of this investigation were to determine optimum tool geometry and cutting conditions for turning Ultra High Strength Alloy Steel (fully heat treated to 120 tons per sq.ins.). The material will be used ...
  • Note on the results of some profile drag calculations for a particular body of revolution at supersonic speeds 
    Wedderspoon, J. R. (College of Aeronautics, Cranfield., 1954-07)
    Details additional to those discussed in College of Aeronautics Report No. 73 are given of the method developed for the calculation of the profile drag of bodies of revolution at supersonic speeds and zero incidence. The ...
  • Note on the velocity and temperature distributions attained with suction on a flat plate of infinite extent in compressible flow 
    Young, A. D. (College Of Aeronautics, Cranfield, 1947-08)
    The problem considered by Griffith and Meredithl for incompressible flow is here considered for compressible flow, it being assumed that there is no heat transfer by conduction at the plate. Essentially, the method consists ...
  • Note on working speeds of some basic clerical operations 
    Willis, M. A. (College of Aeronautics, 1956-02)
    This Note is part of a larger study in the Business Systems Laboratory of the College of Aeronautics on economics of mechanised accountancy. As the subject of performance rates in the clerical operations of adding, multiplying ...
  • Note: estimating the charge size in explosive forming of sheet metal 
    Noble, C. F.; Oxley, P. L. B. (College of Aeronautics, 1964-03)
    Note: Estimating the charge size in explosive forming of sheet metal In the explosive forming of sheet metal some relatively easy method of estimating the size of the charge is needed. This short note describes a method ...
  • Notes on research into some aspects of stall-warning devices 
    Bethwaite, C. F.; Langley, R. A. (College of Aeronautics, Cranfield, 1953-04)
    The problems of detecting and indicating an approaching stall have been investigated in flight on an “Anson” aircraft. A lower-surface flap near the leading-edge of the wing detects the approaching stall at a speed which ...
  • Notes on the feasibility of automatic warehousing
