A method of obtaining numerical values of generalised airforces on a thin wing oscillating harmonically in subsonic flow is described. It is assumed that the linearised equations of potential flow are valid. The essence ...
The whirling of shafts carrying rotors is a subject which has attracted the attention of many engineers and mathematicians notably Dunkerley, Chree, Stodola, Jeffcott and Morris during the past fifty years. The last ...
Two flat parallel surfaces, oscillating harmonically about a mean configuration are immersed in a uniform subsonic main stream in a direction parallel to the surfaces. The linearised equations of potential flow are assumed ...
The thin-jet model, applied by Spence to the study of the jet flap, is combined with the vortex-sheet model, applied by Mangler and Smith to the study of leading-edge separation, to study the effect of blowing from the ...

The vortex-sheet model of leading-edge separation previously applied to flat-plate delta wings has been applied to thick delta wings in the form of rhombic cones. The simplifications introduced by the use of slender-body ...
The linearised theory of supersonic flow is used to calculate the lift slope and the aerodynamic centre of cropped delta wings which have subsonic leading edges. The cropped tip must be short enough for each tip to lie ...
Detailed calculations are made of the flow over a series of bodies at Mach numbers of 1.2, 1.4 and 1.6 and Reynolds numbers of 48 to 72 millions. The bodies consist of a basic forebody and parallel portion to which are ...
The author's treatment of the Mangler and Smith vortex-sheet model of leading-edge separation is extended to the calculation of steady conical flow past a yawed slender delta wing. Introducing yaw destroys the symmetry ...
The influence of damping is examined by comparing the flutter critical speeds and frequencies obtained using the complete equations of motion and those obtained when all the damping terms are omitted. The calculations are ...
