Abstract
A pressure survey of the cavity (plenum chamber) was
conducted on the XR-3 Surface Effect Ship (SES) Testcraft.
The lov/est pressures were observed at 15 knots, and the
highest pressures at 21 knots. Pressure variations with
velocity were observed to be similar in all cases, with a
pressure decrease from 12 to 15 knots, an increase from 15
to 21 knots, a fluctuation and slight decrease from 21 to
24 knots, and a decrease from 2.U- to 26.5 knots. All
pressures have been plotted to show graphically the pressure
variation versus velocity and position within the plenum
chamber from bow seal to stern seal, and from port side to
starboard side. The shape and gradient of pressures was
observed to vary directly with velocity.
