The present paper advances a formula which can be used as a criterion for the degree of mass-balance necessary for the avoidance of spring-tab flutter. The formula shows that if the tab is of sufficiently light construction, ...
The streamwise velocity profile is established as the most suitable basic profile for the calculation of three-dimensional turbulent boundary layers. Measured streamwise profiles are compared with Thompson's two-dimensional ...
In this paper, which is a continuation of two earlier ones (R. & M.'s 2713 & 2717), the subsonic flow past untapered swept wings, at zero incidence, is further investigated using linear theory. Methods for calculating ...
Existing methods of calculating the incompressible turbulent boundary layer have been critically examined and the results that they give compared with a large amount of published experimental data. The investigation has ...
The experiments described in this report are part of a programme of model experiments designed to establish an accurate method for calculating the critical whirling speeds of complex systems. The critical whirling speeds ...
Two well known representations for the crossflow velocity profile, due to Mager and Johnston, are discussed, and limitations to their applicability are outlined. A number of ideas relating to the Johnston triangular model ...
In this paper the results of cumulative fatigue damage studies are given for pinned-lug and clamped-lug specimens in aluminium alloys. The growth of fatigue damage under constant amplitude loading and under variable amplitude ...
This note describes current experiments on laminar-boundary-layer control by suction through perforations. No attempt was made to obtain full-chord laminar flow, as this had been shown previously to be a natural consequence ...
A survey has been made of techniques for producing multiaxial stress conditions on a laboratory scale and it is concluded that one of the more suitable systems is combined tension-torsion of thin-walled tubes. Experimentally ...
