An engineering procedure is suggested for estimating the pressure distribution on the bottom of a stationary ground effect machine of the annular-jet-type. The flow field under the machine was assumed to consist of a core of more or less uniform vorticity separated from the cavity boundaries by a viscous layer. For estimation of pressure on the bottom of the vehicle the core could be approximated under some circumstances by a simple distribution of vortices halfway between the vehicle and the ground empirical relations for the placement and strength of these vortices were based upon available model test data.
