  • 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 ...
  • An investigation of the flow in an axial compressor inlet casing and its effect on the performance of the first stage of the axial compressor 
    Lilley, G. M. (College of Aeronautics, 19)
    Summary The present report is a continuation of an interim report dated 8th August, 1951. The latter- report dealt with the flow in a model casing whereas the present reports deals with a similar investigation on the ...
  • Large scale metrology 
    Scarr, A. J. (College of Aeronautics, 1963-04)
    Introduction This interim note covers some of the problems encountered in the measurement of large sizes, up to 80 inches (200 mm), during investigations carried out at the College of Aeronautics. A description of a ...
  • The lift induced on a circular cylinder by a narrow jet emerging at an angle to the uniform stream 
    Anderson, R. G. (College of Aeronautics, 1955-02)
    SUMMARY A preliminary qualitative study has been made in a smoke tunnel of the flow around a stationary circular cylinder, having rear jet blowing, placed in a uniform stream. Motographs have been taken which show many ...
  • Linear buckling of an axially reinforced pressurised cylinder 
    Houghton, D. S.; Johns, D. J. (College of Aeronautics, 1960-10)
    An analysis is presented using small deflection theory for the buckling of a pressurised, axially reinforced cylinder, which is subjected to axial compression. Various approximations to the analysis are discussed and ...
  • Load compensation techniques using multi-tapped potentiometers 
    Garner, K. C. (College of Aeronautics, 1960-12)
    The theory is developed for loading error compensation techniques utilising multi-tapped potentiometers. Two methods of compensation are derived, and their relative advantages discussed. Design formulae are given for ...
  • Longitudinal stability characteristics and damping in pitch of delta wings 
    McCarter, W. B. (College of Aeronautics, 1954-07)
    The usual technique of longitudinal stability analysis is adopted but particular attention is paid to those elements that contribute to damping, The cases of two delta plan form. aircraft of 45° and 60° sweep angle are ...
  • A low-constraint, high-pressure air feed system for wind tunnel balances 
    Alexander, A. J. (College of Aeronautics, 1963-10)
