چکیده
SUMMARY A two-parameter integral method is developed for predicting the mean-flow characteristics of high-speed axisymmetric turbulent mixing layers with large temperature differences. Results are presented graphically and in tabular form for such quantities as spreading rate, entrainment velocity, potential-core length and velocity along the dividing streamline. These results are for the case of a jet issuing into a quiescent medium; a range of jet Mach numbers from 0 to 5 is taken. For each Mach number results are presented ocrresponding to values of the temperature ratio across the mixing layer ranging from 0 to 00. On the whole the available experimental data agree well with the theoretical predictions. Results for the case where the jet issues into a moving stream are not presented graphically or in tabular form, but approximate analytical formulae are given whereby most of the quantities of interest may be determined.

SUMMARY Theoretical analyses are made of the influence of the following features on the longitudinal shear and transverse tensile moduli of unidirectional fibre reinforced composites: (i) random variations in positioning of individual fibres, (ii) overall variations leading to fibre bunching, (iii) overall variations leading to interspersed matrix layers, (iv) localised variations resulting in ...

SUMMARY The variability of fatigue damage from flight to flight is examined for a fleet of aircraft, both within aircraft and between aircraft. A method is described of modifying the standard analysis of variance technique to take account of correlation between consecutive flights and an example is given. It is then shown how to use the estimates of variance so obtained in the derivation of fac...

SUMMARY Chordwise pressure distributions were measured at several spanwise stations on a two-dimensional model wing fitted with a plain-hinged, trailing-edge flap, at a Reynolds number of 1.9 x IO6 based on chord. The flap was divided into two parts and was deflected to a maximum of 5'. When the flaps were deflected differentially, the transition from a pressure distribution characteristic of t...
