Abstract
Abstract This bistable fluidic amplifier has a converging-diverging, beam- or power-jet-forming inlet nozzle, the diverging sides being extended to form an interaction chamber with laterally spaced output ports opposite the inlet nozzle. A control pressure manifold is disposed at each side of the interaction chamber and a plurality of spaced sets of control pressure inlet nozzles lead from the manifold to the interaction chamber. The control pressure inlet nozzles are of different widths and serve to distribute the control flow into the interaction chamber to deflect the power jet beam over a wide range of supply pressures. As the supply pressure is varied, the flow issuing from the inlet nozzle into the interaction region varies between subsonic, sonic and supersonic flow.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A bistable fluidic amplifier, comprising: a. body means forming an interaction chamber with a beam-forming inlet nozzle at one side and spaced output ports at the opposite side, said means forming sidewalls leading from the sides of said inlet nozzle to the outer sides of said output ports; b. means forming a control pressure inlet port in said body means at each side thereof; c. a control pressure manifold provided in said body means at each side of said interaction chamber, each of said control pressure inlet ports communicating with an adjacent manifold; and d. a plurality of sets of control pressure nozzles leading from said manifolds to said interaction chamber, the control pressure nozzles of each set being spaced along said sidewalls at different distances from said beam-forming nozzle than the control pressure nozzles of the other sets and oriented in a manner to cause control fluid jets issuing therefrom to strike the beam flowing from the inlet nozzle at different distances from such nozzle.
Claim 2
Dependent Claim
166 words
A bistable fluidic amplifier, comprising: a. body means forming an interaction chamber with a beam-forming inlet nozzle at one side and spaced output ports at the opposite side, said means forming sidewalls leading from the sides of said inlet nozzle to the outer sides of said output ports; b. means forming a control pressure inlet port in said body means at each side thereof; c. a control pressure manifold provided in said body means at each side of said interaction chamber, each of said control pressure inlet ports communicating with an adjacent manifold; and d. a plurality of sets of control pressure nozzles leading from said manifolds to said interaction chamber, the control pressure nozzles of each set being spaced along said sidewalls at different distances from said beam-forming nozzle than the control pressure nozzles of the other sets and oriented in a manner to cause control fluid jets issuing therefrom to strike the beam flowing from the inlet nozzle at different distances from such nozzle.
Claim 3
Dependent Claim
28 words
The bistable fluidic amplifier of claim 1 in which the beam-forming inlet nozzle has converging-diverging sidewalls, tHe interaction chamber being bounded on the sides by the diverging sidewalls.
Claim 4
Dependent Claim
16 words
The bistable fluidic amplifier of claim 1 which the control pressure nozzles are of different widths.
Claim 5
Dependent Claim
27 words
The bistable fluidic amplifier of claim 1 in which one set of control pressure nozzles is disposed closely adjacent the exit end of said beam-forming inlet nozzle.
Claim 6
Dependent Claim
29 words
The bistable fluidic amplifier of claim 1 in which the control pressure nozzles nearest the beam-forming nozzle are narrower in width than the control pressure nozzles more remote therefrom.
Claim 7
Dependent Claim
19 words
The bistable fluidic amplifier of claim 1 in which at least two sets of control pressure nozzles are provided.
Claim 8
Dependent Claim
48 words
The bistable fluidic amplifier of claim 6 in which the first set of control pressure nozzles is disposed closely adjacent the exit end of the beam-forming inlet nozzle and the next set is disposed downstream a distance equal to a predetermined number of widths of the beam-forming nozzle.
