Summary

The distribution of pressure over a lifting surface in subsonic potential flow is investigated by means of a three-dimensional electrical potential analyser. It is shown that by using the linear perturbation theory it is possible to obtain the pressure distribution for small angles of incidence, as well as the slope of the lift-incidence curve, easily and rapidly. A comparison with results obtained by vortex theory calculation shows a good agreement in spite of the relatively coarse network which was used for the experiments. There are no practical limitations to the use of a network having a finer mesh, and problems concerning curved and twisted surfaces may also be studied with facility by the use of the potential analyser.
