Abstract : A description is presented of the development of a new porous material that was undertaken specifically for the application of area suction boundary layer control to underwater vehicles. This material was subsequently used in the manufacture of several hydrodynamic test models varying in size from 2 in. to 12 3/4 in. O.D. The small models have been tested and reported to show boundary layer stabilization and the larger models are awaiting tests at the Ordnance Research Laboratory. A unique property of this design has been found in its ability to recover its original porosity with simple back flushing, but more detailed studies would be required to identify the extent of this characteristic.
