A flow guide body for an aircraft includes a main body having an outer aerodynamic surface having a plurality of outlet openings, and flow control devices, each having an inlet, an interaction chamber, a first outlet and a second outlet. A first control inlet is connected to the interaction chamber at the first side of the chamber axis. The outlets are each connected to outlet openings in the aerodynamic surface. Each outlet has a control outlet. A second flow control device is arranged such that one outlet is connected with the inlet of the first flow control device. One of the control outlets of the first flow control device is connected to the first control inlet of the first flow control device, and the other of the control outlets of the first flow control device is connected to the first control inlet of the second flow control device.

The disclosure provides a novel system and method of storing multi-bit information, including providing a nano-channel-based polymer memory device, the device having at least one memory cell comprising at least two addition nano-channels, each of the addition nano-channels arranged to add a unique chemical construct (or codes) to the polymer when the polymer enters the respective addition nano-channel, the polymer having a bead or origami on a non-writing end of the polymer; each nano-channel having a nano-port constriction having a port width which allows the polymer to pass through the nano-port, and does not allow the bead or origami to pass through and does not allow addition or deblocking enzymes (or beads attached thereto) to pass through the nano-port; successively steering the polymer through the nanopore into the addition nano-channels to add the codes to the polymer based on a predetermined digital data pattern to create the digital data pattern on the polymer.

The invention relates to fluid actuator for influencing the flow along a flow surface through ejection of a fluid. By means of a like fluid actuator, a continuous flow is distributed to at least two outlet openings in order to generate fluid pulses out of these outlet openings. Control of this distribution takes place inside an interaction chamber which is supplied with fluid flow via a feed line. Into this interaction chamber there merge at least two control lines via control openings to which a respective different pressure may be applied. Depending on the pressure difference at the control openings, the flow in the interaction chamber is distributed to the individual outlet openings.
