  • Holloway, W. G.; Kumar, P. E.; Osbourn, W. (College of Aeronautics, )
    This note covers the development of two strain-gauge balances for use on the Whirling Arm Facility of the College. The main requirements for this balance were:- (a) to withstand 700 lbs of sideload without it interfering ...
  • Taylor, A. F. (College of Aeronautics, )
    Comparatively little has been published on ‘heavy current’ fluidic devices yet their advantages suggest that they have a place in aircraft fluid systems. As a first brief step towards assessing their value to the aircraft ...
  • Ashill, P. R.; Osbourn, E. W. (College of Aeronautics, )
    The calibration of the flow in the channel of the Whirling Arm is described and results for pitch yaw and wind speed are presented. These indicate that the flow is quite acceptable for the type of model tests envisaged.
  • Lefebvre, Arthur Henry; Norster, E. R. (College of Aeronautics, )
    Introduction and Summary Perhaps the most important and, at the same time, most difficult Problem in the design and development of gas turbine combustion chambers, is that of achieving a satisfactory and consistent ...
  • Gaster, M. (College of Aeronautics, )
    Flight tests on the Handley Page suction wing showed that turbulence, generated at the wing root, can propagate along the leading edge and cause the whole flow to be turbulent. The flow on the attachment line of a swept ...
  • Laurie-Lean, D. W. (College of Aeronautics, )
    The longitudinal dynamic response characteristics of a twin-engined propeller-driven aircraft determined from flight measurements are presented and compared with predictions based on theoretical studies. Transient responses ...
  • Kirk, Colin L. (College of Aeronautics, )
    Experimental determination of the natural frequencies of a stiffened cantilever plate reveals the simultaneous excitation of two normal modes of vibration. Comparison is made between the experimental nodal pattern and ...
  • Johns, D. J. (College of Aeronautics, )
    Introduction Since the College of Aeronautics was founded in 1946 aeroelasticity has been the subject of much research by both students and staff in the Departments of Aircraft Design and Aerodynamics. It is not the present ...
  • Kumar, P. E. (College of Aeronautics, )
    The old Whirling Arm o-r the National Physical Laboratory has been re-erected at the College to provide a facility for the study of ground effect on wings, and other craft operating near the ground. The model is mounted on ...
  • Bradley, W. G. (College of Aeronautics, )
    This note describes the measurement of the moments of inertia in roll, pitch and yaw of a Hawker-Siddeley (de Havilland) Dove Mk. 5 aircraft, using a spring-restrained oscillation technique. Using the present equipment ...
  • Boyd, E. A. (College of Aeronautics, )
    Analytical expressions are obtained for the optimum shapes which minimise the drag of a slender axisymmetric body in free-molecular flow, provided the drag expression is simplified using the slenderness assumption. The ...
  • Christopher, P. A. T. (College of Aeronautics, )
    The problem of longitudinal stability and control of an airframe, having nonlinearity in its principal aerodynamic characteristics, is considered. It is shown that the equation describing the response in w, and thus the ...
  • Hyde, David (College of Aeronautics, )
    In 1963 K.G. Wilkinson, then Assistant Chief Engineer of British European Airways, emphasised the lack of formal engineering education in the maintenance and operation of aircraft. This report describes the nine-month ...
  • Chan, H. S. Y. (College of Aeronautics, )
    In the theory of two-dimensional Michell optimum structures, there arises the problem of calculating the lines of principal stresses and the virtual displacements which are analogous to slip lines and velocities in plane ...
  • Ashill, P. R. (College of Aeronautics, )
    Theoretical and experimental research into the aerodynamics of ram wings is reviewed. The theories of two-dimensional and finite wings in ground effect are discussed and mention is made of the various experimental techniques ...
  • Craven, A. H.; Alexander, A. J. (College of Aeronautics, )
    Wind tunnel tests have been made at M = 2 on a 75° swept delta wing in order to study the progressive breakdown of the leading edge vortices, which occurs at high incidence. The incidence at which vortex breakdown occurred ...
  • Jones, D. A.; Reason, B. R. (College of Aeronautics, )
    An investigation has been carried out, using statically loaded steel and 'Perspex' discs, into elastic displacements occurring at the axial extremities of the Hertzian flat. By employing the technique of 'Photostress', ...
  • Newell, A. F.; Howe, D. (College of Aeronautics, )
    Aircraft Design has been taught at the College of Aeronautics since 1946. The course is at postgraduate level and is of two years duration. In the first year the students are given three exercises in component design which ...
  • Bradley, W. G. (College of Aeronautics, )
    This note describes the measurement of the moments of inertia, of a Morane-Saulnier M.S.760 'PARIS' aircraft. The moments of inertia in pitch, roll, and yaw were measured by the spring-constrained oscillation method. The ...
  • Lefebvre, A. H. (College of Aeronautics, )
    A correlating parameter for gas turbine combustion performance, based on a 'burning velocity' theory for primary zone combustion is derived using a more direct approach than that originally employed by Greenhough and Levebvre.1 ...
