The symmetric response of a tri-jet transport aircraft to continuous atmospheric turbulence and to discrete ramp gusts has been calculated and compared with the results of flight measurements. The aircraft was represented ...
The problem of calculating the rotary lateral stability derivatives for a straight wing with a thin jet emerging at the trailing edge is considered. Based on Maskell and Spence's analysis of the effect of finite aspect ...
The results of some electric tank tests by Duquenne and Grandjean on wings of 45 deg sweepback with trailing edge flaps have been analysed to provide the basis for a method of calculating the spanwise loading. The analysis ...
By a modification of the method used to calculate the profile drag of aerofoils a method has been developed for calculating the drag of smooth bodies of revolution. This method has been applied to three bodies at zero ...
Summary. In two-dimensional potential flow the combination of a source and a free vortex produces an axis-symmetric flow with streamlines in the form of equiangular spirals. Calculations have been made of the turbulent ...

According to the linearized theory of supersonic flow, both the local slope of the mean surface of a wing producing a specified distribution of lift and the pressure on a wing due to a specified distribution of volume are ...
A boundary layer development was measured on the rear of a wing swept at 61°. The measurements approximately followed an external streamline from the minimum pressure to the neighbourhood of the separation line. Unfortunately ...
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 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 ...
