There is a need for high speed wind tunnels of modest dimensions and costs in establishments teaching the fundamentals of compressible flow. This paper discusses briefly the layouts and performances of various types of tunnel which might be suitable for colleges and universities. The subject is still in its infancy and this report should not be...

This article appeared in the first volume of a series on Advances in Appplied Mechanics, started in 1948. The author had been invited by the editors to contribute a survey of work done in The Netherlands during the Second World War, in the field of applied mechanics. In particular in the field of elasticity. The article describes work carried...

This report considers the effect of the walls of a closed rectangular wind tunnel on the aerodynamic forces experienced by an aircraft model mounted close to the tunnel floor. This mounting position is used in determining the "ground-effect" on an aeroplane flying close to the ground. Previous results for the effect of the walls on the angles of...

Curves are given of the vertical component of induced velocity. These are particularly suited to determining contour lines. A graph of contours of induced horizontal velocity is included, and reference is made to a report which gives curves of cable length for desired end points. By the use of these sets of curves, some details of trailing bomb...

An attempt has been made to correlate the lift and hinge moments measured in flight on a Harvard II aircraft with those obtained in wind tunnel tests of a 0.40 scale model of the outer wing panel. For the purpose of comparison, both model and full scale results were reduced to the common case of an aircraft with an infinitely rigid wing, no tail...

Flight measurements of longitudinal stability power off and power on made on numerous aircraft have been analysed and a generalised curve for estimating the contribution of slipstream to longitudinal stability, applicable to both flaps up and flaps down cases, has been derived. Using this curve the change in stability due to slipstream at a...
