Abstract:
A system and method for reducing or increasing the mechanical structure resonance of a synthetic jet device is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof, thereby changing a volume within the chamber so that a series of fluid vortices is generated and projected out from the orifice of the spacing component. At least one of the first and second plates includes a modified section that alters a mechanical resonance of the synthetic jet device, so as to control a level of acoustic noise generated by the synthetic jet device.
Abstract:
A control valve assembly (22) includes an inlet (16) for receiving a gas flow and an outlet (20) for providing the gas flow to a gas burner (18). The assembly (22) also includes a positive-shutoff valve (24) for interrupting the gas flow from the inlet (16). A micro electromechanical system (MEMS) valve (26) is coupled in series to the positive-shutoff valve (24) between the inlet (16) and the outlet (20) for regulating the gas flow from the inlet (16) to the outlet (20).

Abstract:
Es wird ein Verbindungsstück (50) zum Verbinden eines ersten Blattsegmentes (52) und eines zweiten Blattsegmentes (54) eines Rotorblattes (16) einer Windkraftanlage (10) offengelegt. Das Verbindungsstück 50 enthält einen Körper (60), wobei der Körper (60) eine Außenoberfläche (62) und eine Innenoberfläche (64) enthält. Die Außenoberfläche (62) hat eine aerodynamische Kontur, die im Wesentlichen einer aerodynamischen Kontur des ersten Blattsegmentes (52) und des zweiten Blattsegmentes (54) entspricht. Der Körper (60) enthält eine sich zwischen einer Vorderkante (76) und einer Hinterkante (78) erstreckende Druckseite (72) und eine Saugseite (74). In einigen Ausführungsformen enthält das Verbindungsstück (50) ferner einen in der Außenoberfläche (62) des Körpers (60) definierten Kanal (80). Der Kanal (80) enthält eine im Wesentlichen zusammenhängende Basiswand (82), die sich zwischen gegenüberliegenden Seitenwänden (84, 86) erstreckt. Die Innenoberfläche (64) enthält die Basiswand (82). In weiteren Ausführungsformen enthält das Verbindungsstück (50) ferner einen in dem Körper (60) definierten Kanal (80) und eine sich von dem Körper (60) aus im Wesentlichen in Spannenrichtung erstreckende Schale (90).
Abstract:
