  • Design project 1968/9: report of assembly process committee 
    College of Aeronautics, (Cranfield) (College of Aeronautics, 19)
    This report describes the approach to the design of an automatic versatile assembly machine of modular construction. Details of the design of the conveyor module, the platen upon which the assembly is mounted and the ...
  • Design project 1968: final report of Technical Survey Committee 
    Scarffe, M. F. (College of Aeronautics, 1968-06)
    A survey has been made to determine the factors influencing the design of a precision turning machine with limited milling facilities. Seventy six replies were received, have been analysed and histograms plotted and ...
  • Design project 1968: report of the design committee 
    Jones, R. V. (College of Aeronautics, 1968)
    This report outlines the design of a versatile low cost 'Precision Turning Machine with a Limited Milling Facility' which automatically produces work accurately to the required fora at a high production rate. The moving ...
  • Design study for noise tests on laminar flow fin 
    Unknown author (College of Aeronautics, 1965-02)
    The study deals mainly with engineering problems associated with the introduction of a noise generating facility on 'Lincoln' aircraft R.F.342 for the purpose of studying the effect of high intensity sound pressure ...

    Sutcliffe, R. S.; Morrison, W. (College of Aeronautics, 1967)
    This report outlines the recommendations of the Frame Design Committee for the final design of the machine, each major part of the structure being considered individually in the following sections : 1. Worktables 2. ...
  • Drum atomisation studies 
    Norster, E. R. (College of Aeronautics, 1964-09)
    Studies have been made into the behaviour of rotating drums as a means of atomisation and fuel injection for gas turbine engines. Radial holes in the wall of the drum discharge liquid continuously, forming jets which ...
  • Ductility, its measurement and relevance to sheet metal forming operations 
    Pearce, Roger (College of Aeronautics, 1966)
  • The effect of grain size on workhardening and superplasticity in Zn/0.4% Al Alloy 
    Naziri, H.; Pearce, R. (College of Aeronautics, 1969-06)
    Superplasticity*requires, amongst other things, a metal with a grain-size in the range 0.5-5μ. Theories of SP invoking dynamic recovery require that the cell-Size of the substructure for the alloy in question is larger ...
  • The effect of lift-system airflow on the hull aerodynamics of hovercraft 
    Andrews, E. J. (College of Aeronautics, 1965)
    A first generation of commercial amphibious hovercraft has now been operating on a scheduled basis with revenue payloads on relatively-short over-water routes. On some of these routes, open-sea conditions prevail. By ...
  • Entrainment by axisymmetric jets impinging on a flat plate 
    Nobbs, K. W.; Searle, N. (College of Aeronautics, 1966-01)
    An experimental technique is described for the determination of the entrainment in an axisymmetric gaseous jet impinging normally on a flat plate situated below the nozzle. Typical results are given of experimental work ...
  • Extended plasticity in commercial-purity zinc 
    Williams, D. A. C.; Naziri, H.; Pearce, R. (College of Aeronautics, 1968-09)
    90% rolling-reduction of annealed commercial-purity zinc sheet (grain size 100 - 150 μ) results in the fragmentation of the large grains into, finally, stable micro-grains, 1 - 211 in diameter. The stability of the ...
  • Extended plasticity in commercial-purity zinc sheet
