Description

Regeleinrichtung für den Kühllufteintrittsquerschnitt von Verkleidungshauben luftgekühlter, zum Antrieb von Verstelluftschrauben dienender Flugmotoien Die Erfindung bezieht sich auf eine Regeleinrichtung für den KühllufteintrittsquerschnittvonVerkleidungshauben luftgekühlter, zum Antrieb von Verstelluftschrauben dienender Flugmotoren, die im wesentlichen bestehen aus einer äußeren, offenen Nabenhaube und einer inneren, geschlossenen, in Achsrichtung verschiebbaren Nabenkappe, deren Verstellung durch Verbindung mit der Luftschraubenverstelleinrichtung gleichzeitig mit dem Verändern der Stellung der Luftschraubenblätter erfolgt.Control device for the cooling air inlet cross-section of cladding hoods air-cooled flight motifs used to drive adjustment propellers. The invention relates to a control device for the cooling air inlet cross-section of cladding hoods air-cooled aircraft engines used to drive Verstelluftscrews, which are in the essentially consist of an outer, open hub cap and an inner, closed, Axially displaceable hub cap, which can be adjusted by connecting with the propeller adjustment device at the same time as changing the position of the propeller blades.

Um das Einstellen bzw. Verstellen derartiger Nabenkappen möglichst einfach und betriebssicher zu gestalten, wird erfindungsgemäß vorgeschlagen, die Nabenkappe derart mit den in unmittelbarer Nähe der Kappe angeordneten Luftschraubenblättern bzw.-deren Verstelleinrichtung zu verbinden, daß mit dem Verändern der Stellung der Luftschraubenblätter gleichzeitig eine Verstellung der Nabenkappe zwecks Änderung des Luftdurchtrittsquerschnittes erfolgt.To adjust or adjust such hub caps as possible To make simple and reliable, the invention proposes that Hub cap in such a way with the propeller blades arranged in the immediate vicinity of the cap or-their adjusting device to connect that with changing the position the propeller blades at the same time an adjustment of the hub cap for the purpose of change of the air passage cross-section takes place.

Dieser Regelvorgang kann je-nach den gewünschten Betriebsverhältnissen des Motors bzw. der Ausbildung der Einlaßkanäle und deren Regelmöglichkeit sowohl parallel zu ,einer anderen in an sich 'bekannter Weise ausgebildeten, Regeleinrichtung stattfinden als auch als ausschließliches Mittel zum Ändern der dem Motor zugeführten Luftmengen dienen.This regulating process can depend on the desired operating conditions of the engine or the formation of the inlet ducts and their control options both parallel to "another control device designed in a manner known per se" take place as well as the exclusive means of changing the amount supplied to the engine Serve air volumes.
