An expression has been derived for the factor to he applied to ideal induced drag to allow for Wing-tail interference. This factor is primarily dependant on the wing-taillift and span ratios. It is of the order of 1.1 for ...
The existing data have been analysed and a method has been derived for predicting the lift and profile-drag increments of split and slotted flaps. It is suggested that the probable order of error involved in the method is ...
A summary of the first ten flights made with a heat-transfer vehicle is given together with some of the salient features of the results relative to conical and hemispherical heads. The method of reducing the temperature ...
The tail-first aeroplane has certain strong attractions when combined with a tricycle undercarriage; in particular it has been suggested that it would represent a definite advance in the production of high lift. In these ...
Very little has been recorded during the war years as to the details of technique used in low-speed wind-tunnel tests. The size and type of tunnel used during this period will remain in use at firms and colleges for some ...
These notes aim at providing a framework to display what is known of the backward movement of the aerodynamic centre of wing shapes likely to be used for transonic operation, as the flow progresses from incompressible ...
Summary. A brief review of oscillatory theories reveals that some of these suffer from a defect that has been corrected in the Algol programme now subject to critical examination. Its features in steady and low-frequency ...
The previous work of the author in which the subcritical flow past ellipsoids was calculated is extended to supercritical flows. The same ellipsoidal coordinate system is used, the body-surface boundary-condition is then ...
The problem of a subcritical, potential, steady, three-dimensional flow past an unyawed ellipsoid is considered, using ellipsoidal coordinates. The full equations of motion and the exact body surface boundary condition are ...
Numerical solutions of the energy-balance equation of an axially symmetrical uniform arc column are outlined and illustrated with results pertaining to a nitrogen plasma at atmospheric pressure. Published data on the ...
The characteristic 'N' shaped pressure waves recorded at ground level below the flight path of supersonic aircraft have compressive regions very much less steep than predicted by theory, with a consequent reduction in the ...
