Problems solved by technology

Therefore, the risk of failure of such valves is a problematic issue for the approval of such fluid actuators in aviation
In addition, the individual mechanical components of the valve lead to a relatively complex construction, which entails high manufacturing costs due to the many individual components
In addition to the high cost, the mass of the components and the complexity of the construction lead to an increase in weight, which is also a disadvantage of the aircraft in view of the simultaneously increased fuel consumption

Embodiment Construction

[0054] exist figure 1 In , a first embodiment of a fluid actuator 10 of the present invention is shown. figure 1 The fluid actuator 10 of the embodiment includes an outlet device 20 having two outlet openings 24a and 24b. Thus, the fluid actuator 10 of this embodiment serves to obtain pulsation by distributing the fluid flow between the two outlet openings 24a and 24b.

[0055] In order to distribute the air to the two outlet openings 24a and 24b, the feed line 40 is arranged at figure 1 The fluid actuator 10, which guides air and thus the flow of fluid into the figure 1 The interaction chamber 30 is shown in . Within the interaction chamber 30 a flow distribution is performed, ie a major part of the supplied fluid flow from the feed line 40 is distributed in a rotating manner to one of the two outlet lines 22a and 22b, as will be described below. to this end, figure 1 The interaction chamber 30 shown in includes two flow lines 32a and 32b which are connected in fluid com...

Abstract

The present invention relates to fluid actuators that affect flow along a flow surface by injecting fluid. Using similar fluidic actuators, the continuous flow is distributed into at least two outlet openings to generate fluid pulses outside of these outlet openings. The control of this distribution takes place within the interaction chamber, which is supplied with a fluid flow via a feed line. At least two control lines merge into this interaction chamber via control openings to which respective different pressures can be applied. The flow in the interaction chamber is distributed into the individual outlet openings according to the pressure difference across the control openings.

Description

technical field [0001] The present invention relates to fluid actuators that affect flow along a flow surface by jetting the flow flowing through the fluid actuator. Furthermore, the invention relates to a spray device comprising at least one fluid actuator and a fluid body comprising a plurality of outlet openings. Background technique [0002] Such fluid actuators are basically known for, for example, influencing the flow along the flow surface of a flow body. Such fluid actuators are utilized, for example, to cause flow to adhere for a longer period of time along the flow body, or to reattach flow to the flow body that has detached or detached from the flow body. This is advantageous and beneficial, for example, when known fluid actuators are applied to fluid bodies in the form of adjustable flaps, control flaps or other parts of wings of an aircraft. [0003] In order to reattach a flow which has been detached from the flow body, it is known to realize the fluid actuat...
