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 ...

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 ...

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 ...

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 ...

Summary. Tests have been made on the N.P.L. low-density tunnel on two pressure-plotting cones of 15 deg and 30 deg semi-vertex angle placed at zero incidence to the flow. The stream static pressure was varied between 20 ...

Summary. A survey has been made of the available literature on the aerodynamic loads associated with the external carriage of pylon-mounted stores adjacent to wing-fuselage combinations. The existing methods for estimating ...

Summary. The measurements, using razor blade surface pitot tubes, show that the relatively mild pressure gradients and streamline convergence on the wing have a large effect on local skin friction. Application of the ...

The first part of this report describes the Ngh-speed tunnel installation in the Aerodynamics Division of the National Physical Laboratory. The installation consists of the 12-in. diameter High-Speed Tunnel, the 20 x 8-in. ...

Summary. The equation of motion for a flexible aircraft responding to a step gust is derived, and the relation developed between this and the response to an array of harmonic gusts. A Fourier transform method is used to ...

Summary. The dampings and frequencies of the lower natural modes of oscillation of an aeroelastic, swept-wing model at wind speeds below its critical flutter speed have been deduced from measurements of the displacement-vector ...
