Description
Entlüftungseinrichtung für Außenhautkondensatoren an Luftfahrzeugen Die Erfindung betrifft eine Entlüftungseinrichtung für in Flugzeugbauteile eingebaute Außenhautkondensatoren, die .in bekannter Weise mit einer Dampfzuleitung und einer Kondensatabs.augeeinrichtung versehen sind.Ventilation device for outer skin condensers on aircraft The invention relates to a ventilation device for built into aircraft components Shell condensers, which .in a known manner with a steam supply line and a Condensate extraction device are provided.
Bei der -Entlüftungseinrichtung für Kondensatoren besteht der Mangel, daß die entweichende Luft Dampf und zum Teil auch Wasser mitreißt.There is a defect in the ventilation device for condensers, that the escaping air entrains steam and sometimes also water.
Um diesen Mangel zu beseitigen, wurde vorgeschlagen, die entweichende Luft unter die Kondensatortemperatür zu unterkühlen, um ihr Wasser zu entziehen. Durch die Unterkühlung wird der von der Luft mitgerissene Dampf niedergeschlagen und .dadurch die Luft vor dem Entweichen getrocknet.t Durch die Erfindung wird eine besondere Ausbildung einer Entlüftungseinrichtung für Außenhautkondensatoren geschaffen, -wie sie für Schnellflugzeuge und deren Verdampfungskühl.anlagen besonders vorteilhaft ist. Bei solchen Flugzeugen darf durch den Einbau einer Unterkühlung für die Entlüftungseinrichtung der Außenhautkondensatoren keime Widerstandserhöhung eintreten, die einen Geschwindigkeitsverlust bewirkt. Die Entlüftungseinrichtung muß so gelagert und ausgebildet sein, daß sie keine Wärme vom Außenhautkondensator aufnimmt -und außerdem vom Luftstrom bestrichen wird.In order to remedy this deficiency, it was proposed that the escaping To subcool air below the condenser temperature in order to remove water from it. The supercooling knocks down the vapor carried along by the air and thereby drying the air before it escapes. The invention provides a special design of a venting device for outer skin condensers created, -as they are particularly advantageous for high-speed aircraft and their evaporative cooling systems is. In such aircraft it is allowed to install a subcooling for the ventilation device of the outer skin capacitors germ resistance increase occur, which leads to a loss of speed causes. The ventilation device must be mounted and designed so that it does not absorb any heat from the outer skin condenser - and is also swept by the air flow will.
Nach der Erfindung isst im Außenhautkondensator ein Luftsammelraum, von ihm durch eine Wärmeschutzschicht getrennt, derart angeordnet, daß seine Außenwandung aus einem Teil der vom Fahrtwind bestrichenen -'-#ußenhaut des Kondensators gebildet ist.According to the invention, an air collecting space eats in the outer skin condenser, separated from it by a heat protection layer, arranged in such a way that its outer wall formed from a part of the outer skin of the condenser which is swept by the airstream is.
In der Zeichnung ist ein Ausführungsbeispiel eines Kondensators zur Niederschlagung von Wasserdampf dargestellt.In the drawing, an embodiment of a capacitor is for Deposition of water vapor shown.
Der Flügelinnenraum a ist als Kondensator ausgebildet. Die Luft aus dem Flügelraum wird von den Luftsammelstellen durch die Leitungen b zum Sammelrohr c geleitet. Das Sammelrohr c liegt an' der Außenhaut des Flugzeuges und ist durch eine Isolierschicht d vom Kondensator getrennt. Die Luft wird unterkühlt und gelangt über die Leitung e ins Freie. Durch die Unterkühlung werden mitgerissener Dampf und Wasser zurückgehalten. Die Absaugung des Kondensats erfolgt in bekannter Weise durch Pumpen f. Die Form des Unterkühlers kann im Rahmen der gegebenen Möglichkeiten beliebig sein. Die einzelnen Entlüftungsleitungen können z. B. auch in einen Sammelraum münden, der an der Außenhaut liegt.The wing interior a is designed as a capacitor. The air out the wing space is from the air collection points through the lines b to the manifold c headed. The manifold c is on 'the outer skin of the aircraft and is through an insulating layer d separated from the capacitor. The air is supercooled and gets there to the outside via line e. The supercooling creates entrained steam and water retained. The condensate is suctioned off in a known manner by pumping f. The shape of the subcooler can within the given possibilities be arbitrary. The individual vent lines can, for. B. also in a collecting room open, which lies on the outer skin.
