Abstract

The fluid propulsive device for accelerating flow of a main fluid passing through the device, a main duct having a duct has central axis defined by a duct side wall, a primary jet means adapted to receive working fluid under pressure, the jet means extending peripherally around a portion of the main duc generally within a primary plane disposed normally to the duct axis and adapted to project downstream into the main duct a primary conical spray of working fluid, the spray being inclined initially to the duct central axis at a conical semi-angle of between approximately 15 degrees and 45 degrees so as to converge inwards initially generally towards a theoretical apex of the cone of spray adjacent the central axis.
