    Simplified analyses are presented which illustrate some of the design problems of typical space vehicle structures, with the emphasis on thin, circular cylindrical shells. Amongst the problems considered are panel ...
  • Some notes on the factors influencing the possible damage to buildings due to the passage of shock waves from aircraft flying at supersonic speeds 
    Lilley, G. M. (College of Aeronautics, 1952)
    The purpose of this note is to discuss, from the limited information available, the order of magnitude of the strength and the configuration of the shock waves, close to ground level, generated from aircraft flying et ...
  • Some tests on a circular ground effect machine with forward speed 
    Harris, T. M. (College of Aeronautics, 1962-10)
    Wind tunnel tests have been made on a circular-wing with 90° downward peripheral blowing both in and out of ground effect. Tests made with two slot widths, a range of blowing pressures and choked jets, indicate that Cu ...
  • Some thoughts on a proposed in-flight experiment to study the effect of external noise on a swept laminarised wing 
    Hyde, D. (College of Aeronautics, 1963-04)
    A transducer-horn arrangement has been suggested as a suitable noise source to be installed in the Lancaster aircraft so that the Handley-Page suction fin could be subjected to large acoustical disturbances. The object ...
  • Some thoughts on slender all wing supersonic airliners 
    Spillman, J. (College of Aeronautics, 1958-08)
    The design of slender wing, supersonic airliners has been considered from the viewpoint of obtaining maximum space utilization, A relationship between direct operating cost on trans-atlantic services and space utilization ...
  • Some values of the reduction factor for plastic buckling of plates in shear 
    Emslie, B. (College of Aeronautics, 1959-01)
    In this note values are obtained for the plasticity reduction factor for plates in shear, based on incremental plasticity theory. These values are compared with other theoretical results and with some experimental results.
  • Spontaneous -ignition data of hydrocarbons and aviation fluids 
    Goodger, E. M. (College of Aeronautics, 1957-09)
    The standard A.S.T.M. method has been used to determine comparative spontaneous-ignition characteristics of 29 hydrocarbons and aviation fluids. Reasonable correlation is found with results from more precise methods. ...
  • Stability of a rotating cylindrical shell partially filled with liquid 
    Ward, G. N. (College of Aeronautics, 1957-03)
    The theory of the stability of a gyroscope which has a right circular cylindrical cavity partially filled with liquid has been developed by Stewartson (reference 1), who has shown that instabilities occur at and near ...
  • The stability of honeycomb sandwich panels in shear 
    Nichols, R. (College of Aeronautics, 1956-10)
    This abstract presents the results obtained by theoretical and experimental methods for the buckling of honeycomb sandwich panels in shear. Details of the specimens analysed are shown in Figs. 1 and 2. The test rig is ...
  • Stress distribution in a pressurised thick walled toroidal shell: a three dimensional analysis 
    Kornecki, A. (College of Aeronautics, 1963-01)
    An investigation is made into the state of stress in a closed toroidal shell of uniform thick-walled circular cross section, when loaded by uniform internal and external pressures. The general equations of the classical ...
  • Study of heat and mass transfer from non-isothermal surfaces 
    Smith, A. G. (College of Aeronautics, 1962-11)
    N/A
  • Supersonic flutter of cylindrical shells 
    Johns, D. J. (College of Aeronautics, 1960-06)
    The general theories of thin elastic cylindrical shells as derived by Love and Novozhilov are compared and then used in a simple binary flutter analysis which permits the existence of both axial and circumferential waves ...
  • Teaching machines for teaching work study 
    Wiltshire, H. C. (College of Aeronautics, 1963-05)
    Machines which have been used successfully for the teaching of work measurement practices are described. Although designed to shorten the period of instruction for beginners) they appear to be suitable for postgraduate ...
  • Thermal buckling of a free circular plate 
    Webber, J. P. H. (College of Aeronautics, 1960-08)
    The buckling of a free circular plate subjected to a temperature field, which varies only in the radial direction, is considered. The problem is first investigated experimentally and the mode of deflection and form of ...
  • Thermal stresses in a box structure 
    Lempriere, B. M. (College of Aeronautics, 1958-07)
    This interim note presents an analysis, using an energy method, of the thermal stresses in a finite length box structure resulting from uniform skin heating. The solution depends upon an eighth order differential equation ...
  • Thermal stresses in thin cylindrical shells, stiffened by plane bulkheads, for arbitrary temperature distributions 
    Johns, D. J. (College of Aeronautics, 1958-07)
    A study has been made of the thermal stresses reulting near the joint of a cylinder and internal bulkhead due to arbitrary temperature distributions in the configuration and to the consequent compatability forces and ...
  • A transistorized radiation monitor 
    Brown, D. C.; Faraday, B. P. (College of Aeronautics, 1956-12)
    This paper describes the investigation of a number of possible semiconductor devices which can be used for the detection of radioactive particles. The sensitivities of two types of transistor (a p-n-p alloy junction and ...
  • Trends in aircraft design 
    Newell, A. F.; Howe, D. (College of Aeronautics, 1962-05)
    The improved performance of aircraft during the past decade has resulted in the need for new design and production techniques. Particular examples are integral construction and the use of sandwich panels. Although these ...
