A Survey of the Pressure Distribution Within the Plenum Chamber of the XR-3 Testcraft.
Abstract
A pressure survey of the cavity (plenum chamber) was conducted on the XR-3 Surface Effect Ship (SES) Testcraft. The lowest 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 24 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.
