Abstract

Die Erfindung betrifft Adaptive Kühler/Wärmetauscher, wobei diese durch einen wärmeaktiven Aktor mit angebundenem mechanischem Klappensystem sich im Flugbetrieb selbst regulieren.The invention relates to adaptive coolers / heat exchangers, whereby these regulate themselves during flight operations by means of a heat-active actuator with a connected mechanical flap system.

Description

Die Erfindung betrifft einen adaptiven Kühler/Wärmetauscher mit ausgeprägtem Meredith-Effekt.The invention relates to an adaptive cooler / heat exchanger with a pronounced Meredith effect.

Der Meredith-Effekt: Waagerechte Anordnung eines stromlinienförmigen Kühlers erzeugt Vorschub, abhängig von einer gewissen Fluggeschwindigkeit, einer bestimmten Kühlerkanalgeometrie und einem bestimmten Verhältnis von Einzu Austrittsöffnung. Somit kann ein Flugzeug mit einem solchen Kühler in seiner Gesamtkonfiguration widerstandsminimiert werden.The Meredith effect: a horizontal arrangement of a streamlined cooler generates feed, depending on a certain airspeed, a certain cooler duct geometry and a certain ratio of inlet to outlet opening. The overall configuration of an aircraft with such a cooler can thus be minimized.

Die Funktionsweise eines adaptiven Aktors und das damit verbundene mechanische Klappensystem wird in 1 schematisch dargestellt und entsprechend erläutert:

  • Da der Kühler abhängig vom abzuführenden Wärmestrom und der Fluggeschwindigkeit reguliert werden muss, um den Mereditheffekt maximieren zu können, wird zur Regulieren die Austrittsöffnung des Kühlerkanal durch eine bewegliche Klappe benutzt. Ein wärmeaktiver Aktor reagiert auf die Temperatur und deren Änderung am Kühler. Wird der Kühler wärmer, verformt er sich und lenkt über eine mechanische Verbindung die Austrittsklappe aus, wodurch der Volumenluftstrom erhöht wird und damit die Kühlleistung. Dadurch sinkt die Temperatur am Kühler, wodurch die Austrittsklappe wieder leicht durch den Aktor geschlossen wird. Dadurch ist eine Selbstregulierung realisiert. Vorteil: Gewichtseinsparung des Aktors und
  • Einsparen der Ansteuerung und der äußeren Systemregulierung, also Systemvereinfachung. Eine kontinuierliche Aktuation ist möglich Der betreffende Werkstoff kann aus wärmestimulierenden Kunststoffen oder Verbundmaterial sein, dessen Fasern aus Gedächtniswerkstoffen, wie Formgedächtnislegierungen.
The functionality of an adaptive actuator and the associated mechanical flap system is shown in 1 shown schematically and explained accordingly:
  • Since the cooler has to be regulated depending on the heat flow to be dissipated and the airspeed in order to be able to maximize the meredithe effect, the outlet opening of the cooler duct is used for regulation by a movable flap. A heat-active actuator reacts to the temperature and its change on the cooler. If the cooler becomes warmer, it deforms and deflects the outlet flap via a mechanical connection, increasing the volume air flow and thus the cooling capacity. As a result, the temperature on the cooler drops, which means that the outlet flap is easily closed again by the actuator. This realizes self-regulation. Advantage: weight saving of the actuator and
  • Saving of control and external system regulation, i.e. system simplification. Continuous actuation is possible. The material in question can be made of heat-stimulating plastics or composite material, the fibers of which are made of memory materials, such as shape memory alloys.
