  • Factors affecting punching speeds of hollerith operators. Mechanical factors outside the control of the operators 
    Majewski, T. R. (College of Aeronautics, 1954-06)
    One of the major influences governing punching speeds is the operator's reaction to what she regards as the innate stiffness of the punch. This Note reviews those factors which are attributable to the machine rather ...
  • Flight tests on a torquemeter installed on Gipsy Queen 71 engine on dove aircraft 
    Robertson, I. A. (College of Aeronautics, 1955-02)
    The torquemeter failed at 178 hrs. 50 minutes flying. Torquemeter powers compared with engine powers deduced from maker's curves give the following results: 1) At low BHP readings the torquemeter tends to over-read 2) ...
  • The flutter of thin, plane, elliptic panels 
    Johns, D. J. (College of Aeronautics, 1963-01)
    The effect of various parameters on the flutter of elliptic panels is studied by simple theoretical analyses. For clamped edge panels, compressive membrane stresses are shown to have destabilising effects. Structural ...
  • A framework for compensating rest allowance 
    Belbin, R. M. (College of Aeronautics, 1955-10)
    A great many papers have been written on the subject of human fatigue but the complaint is often made in industry that, while many of these studies may be of scientific value, it is very difficult to see how they may ...
  • The free-molecule flow characteristics of concave surfaces 
    Pratt, M. J. (College of Aeronautics, 1963-06)
    The problem of free molecule flow over concave surfaces is investigated, and general equations formulated for the lift, drag, and heat transfer characteristics of such surfaces. The effect of multiple reflections is ...
  • Grinding theory 
    Hillier, M. J. (College of Aeronautics, 1962-09)
    This report presents a review and extension of current grinding theory. Grinding operations are classified on the basis of (a) the cutting action of the grit, (b) the geometry of wheel and work, (c) the type of chip ...
  • Ground level disturbance from large aircraft flying at supersonic speeds 
    Lilley, G. M.; Spillman, J. J. (College of Aeronautics, 1960-05)
    The Whitham-Walkden theory for the estimation of the strength of shock waves at ground level from aircraft flying at supersonic speeds is applied to the case of a typical projected supersonic civil transport aeroplane. If ...
  • Heat conduction through a gas with one inert internal mode 
    Clarke, J. F. (College of Aeronautics, 1960-05)
    The rate of energy transfer between parallel flat plates is evaluated when the (stagnant) gas between them is polyatomic with one inert internal mode. Deviations of the thermal conductivity from the complete equilibriu ...
  • 'Heat transfer at low temperature in the entry section of a solid propellant rocket nozzle' 
    Smith, A. G. (College of Aeronautics, 1962-04)
    Heat transfer in the converging section of the nozzle of a simulated solid propellant rocket with a star-shaped conduit has been investigated in the following way: (a) Area-average heat transfer has been measured on a ...
  • Heat transfer through an incompressible laminar boundary layer 
    Shah, V. L. (College of Aeronautics, 1962-09)
    The study of the boundary layer theory has been done by reviewing briefly the boundary layer concept, the boundary layer equations, and the exact solutions for wedge flow. All the methods for the calculations of the ...
  • Incompressible flow past bodies of revolution 
    Nonweiler, T. (College of Aeronautics, 1955-07)
    In this paper we shall attempt to review the existing information, both theoretical and experimental, which relates to same of the more important aerodynamic problems arising in the study of the flaw over bodies of ...
  • The influence of engine speed upon pre-ignition 
    Goodger, E. M. (College of Aeronautics, 1956-09)
    The literature shows conflicting evidence on the effect of engine speed upon tendency to pre-ignition. Typical published results are presented and compared, together with results obtained from a single-cylinder D.V.L. ...
  • The influence of frame pitch and stiffness on the stress distribution in pressurised cylinders 
    Houghton, D. S. (College of Aeronautics, 1958-02)
    An analysis is made of the stresses occurring in stringer reinforced cylinders due to the restraining action of the frames. Graphs are presented showing the effect of variation in frame pitch and stiffness, on the bending ...
  • Initial aircraft weight prediction 
    Howe, D. (College of Aeronautics, 1957-12)
    Although much has recently been published concerning methods for the weight prediction of individual structural components, it is some considerable time since a review of the subject as a whole has appeared. This note ...
  • Initial prediction of guided missile weight 
    Howe, D. (College of Aeronautics, 1957-09)
    In the initial design stages of a guided missile it is essential tc predict the weight as accurately as is possible, and this note is intended to be a guide in this process. The information has been presented in a form ...
  • An interim note on machining super high tensile steel 
    Purcell, J.; Ellis, P.J.; Vicary, D.P. (College of Aeronautics, 1958-09)
    A series of tests have been carried out to determine the machinability characteristics of Ultra High Tensile Steels in the 120 tons sq. ins. T/S range with hardness values of 550 to 600 V.P.N. Tool geometry and cutting ...
  • Interim report on the research into the use of formula for calculating economic batch sizes 
    Robinson, A. (College of Aeronautics, 1959-12)
    This report analyses the replies and subsequent conversations held with companies. Based on this analysis it is shown that various factors have to be considered Then deciding what is an Economic Batch size, and that the ...
  • "Investigation into the use of freon 12 as a working medium in a high-speed wind-tunnel" 
    Pozniak, O. M. (College of Aeronautics, 1957-11)
    The Freon 12 tunnel project at the College of Aeronautics was started to pin experience in the design of such tunnels and subsequently to investigate their use for aerodynamic measurements and the correlation of these ...
  • Investigation of eye movements of an aircraft pilot under blind approach conditions 
    Watts, A. F. A. (College of Aeronautics, 1955-05)
    Eye movement patterns were obtained of a pilot in an aircraft fitted with a standard R.A.F. blind flying panel on several approaches under Standard Beam Approach conditions, These patterns were obtained by photographing ...
