Abstract

The invention provides a pressure flow control device of the type used primarily to maintain both vertical and horizontal stability and manueverability in a predetermined fluid environment. The device includes the first skin of predetermined configuration, a second skin of predetermined configuration disposed in substantially spaced apart configuration relation from the first skin and a plurality of third skin disposed in interconnecting relation between the first and second skins. One or more spors are defined by the first, second and third skins. One end of the spors at least partially defines a leading edge of the device and the opposite end of the spors at least partially defines the trailing edge of the device. One or more holonomic ports are formed in at least one of the third skins and a jet port is defined by at least a portion of one or more of the spors being open at its aft end. Fluid flow through at least a portion of the group consisting of the jet port and the holonomic ports is selectively restricted to control fluid pressures within the one or more spors.
