  The preparation of this bibliography of Heat Transfer Instrumentation was undertaken by the authors at the request of the Heat and Mass Transfer Sub-Committee of the Aeronautical Research Council. It is based upon an initial ...
• A theory of the aerodynamic interference between a helicopter rotor blade and a fuselage and wing in hovering and forward flight 

  A. R. S. Bramwell; J. B. B. Johnston (1965)

  The Report presents a theory of the aerodynamic interference between a helicopter rotor blade and a fuselage or wing. A two-dimensional analysis is made to which a correction factor is applied to convert the two-dimensional ...
• The combination of statistical distributions of random loads 

  N. I. Bullen (1963)

  The case of a Random Gaussian process for which the root,mean-square value is itself variable is considered. A distribution for the root-mean-square value is assumed and an expression is derived for the resulting distribution ...
• Take-off tests on a transport aircraft including the use of a 'SCAT' take-off director 

  C. O. O'Leary; J. N. Cannell; R. L. Maltby (1966)

  A large number of take-off tests have been made on a Comet aircraft with the object of (a) acquiring comprehensive data on undirected take-offs; (b) testing a SCAT take-off director. SCAT is explained in detail and the ...
• A digital computer program for the through-flow fluid mechanics in an arbitrary turbomachine using a matrix method 

  H. Marsh (1966)

  A detailed description is given of the development of a computer program for analysing the flow through axial, radial and mixed-flow turbomachines. The theory is based on the through-flow analysis given by Wu 1,2 and the ...
• Propeller blade vibration nature and severity of vibration at edgewise resonance as influenced by coupling effects due to blade twist 

  J. F. Shannon; J. R. Forshaw (1941)

  Information was required as to the stress distribution in propeller blades occurring at edgewise resonance, and the importance of this vibration relative to the other modes. Tests were carried out on a duralumin-bladed ...
• The performance of fans in Hovercraft -- a method of reducing experimental results 

  A. J. Burgess (1965)

  A method for reducing data on hovercraft fan performance is proposed which is expected to lead to a simplification of model and flight test procedures. The method is shown to be theoretically justified, and supporting ...
• An experimental investigation of the interaction between a forward-facing step and a laminar boundary layer in supersonic, low-density flow 

  E. W. E. Rogers; C. J. Berry; B. M. Davis (1965)
