<p>A fluid amplifier includes an inlet for directing a laminar fluid power stream along a predetermined axis. A control means downstream of the inlet includes a wall spaced laterally outward of the power stream and at least partially enclosing same with a guide surface portion of the wall curving outwardly away from the predetermined axis. An access opening to the power stream in the wall of the control means permits introduction of a perturbant signal to thereby alter the power stream from a laminar to a substantially turbulent flow pattern of a significantly greater cross-sectional dimension. This transition results in formation of a low pressure condition between the stream and the guide surface of the wall causing the stream to attach to the guide surface and divert away from the predetermined axis. Several embodiments and further features are disclosed.</p> |
