Description

Anordnung einer Unterdruckantriebsquelle zum Antrieb von Flugzeugbordgeräten Zum Antrieb von in Luftfahr zeugen angeordnetenHilfsgeräten mittels Unterdruckes ist es bekanntgeworden, den Unterdruck durch eine außerhalb des Luftfahrzeuges liegende, nach rückwärts geöffnete Sonde zu entnehmen und den so aufgefangenen Luftstrom durch eine Rohrleitung in einen Unterdruckraum zu leiten und von dort aus zur Verstärkung des Luftstromes über :ein eingebautes Venturirohr dem im Luftfahrzeug angeordneten Hilfsgerät für den Antrieb desselben zuzuführein. Auch ist es bekannt, den angesaugten Luftstrom durch zusätzliche Einrichtungen zu erwärmen.Arrangement of a vacuum drive source for driving aircraft on-board equipment For driving auxiliary devices arranged in aircraft by means of negative pressure it has become known to reduce the negative pressure by means of a remove the probe opened backwards and let the air flow through it to lead a pipeline into a negative pressure room and from there to reinforcement of the air flow via: a built-in venturi the one arranged in the aircraft Auxiliary device for the drive of the same zuzuführein. It is also known to be sucked in To heat the air flow through additional devices.

Einrichtungen dieser Art sind in der Herstellu g teuer und umständlich in ihrer Bauweise und erfordern beim Einbau in den Flugzeugkörper sehr viel Platz, wogegen die außerhalb des Fahrzeugs angeordnete Sonde einen zusätzlichen Luftwiderstand ergibt.Facilities of this type are expensive and cumbersome to manufacture in their construction and require a lot of space when installed in the aircraft body, whereas the probe arranged outside the vehicle creates additional air resistance results.

Erfndungsgemläß wird daher vorgeschlagen. die Unterdruckantriebsquelle in einem mittels einer Ansaugdüse am Auspuffrohr des Flugzeugmotors mündenden, innerhalb des Flugzeugkörpers verlaufenden Warmluftführungskanal vorzusehen. Dadurch wird erreicht, daß neben einer Verringerung des Luftwiderstandes eine heizbare Düse' )der eine andere umständliche heizbare Antriebsquelle für die Flugzeugbordgeräte erspart wird und daß die Anlage raumsparend im Flugzeugkörper untergebracht werden kann und infolge der einfachen Bauart leichter unter erheblicher Gewichtsersparnis herstellbar -ist.According to the invention, it is therefore proposed. the vacuum drive source in an opening by means of a suction nozzle on the exhaust pipe of the aircraft engine, within to provide the aircraft body extending warm air duct. This will achieves that, in addition to a reduction in air resistance, a heatable nozzle ' ) the other cumbersome heatable drive source for the aircraft on-board equipment is saved and that the system can be accommodated in a space-saving manner in the aircraft body can and due to the simple design easier with considerable weight savings can be produced.

Vorteilhafterweise wird, um den Warmluftstrom weiter auszunutzen, der Zuführungskanal durch ein Abzweigrohr mit weiteren Verbraucherquellen verbunden, die z. h. zum Beheizen von Kabinenräumen oder zur Verhütung von E=isansatz an Flugzeugbauteilen, insbesondere Fensterscheiben, dienen, obgleich es an sich bekannt ist, die Auspufgase des Flugzeugmotors unter Verwendung von Venturirohren zum Beheizen von Kabinenräumen auszunutzen, ebenso wie es nicht mehr neu ist, -zur Verhütung von Eisansatz ,all Fensterscheiben diese mittels Auspult#Z:,sc zu beheizen.Advantageously, in order to further utilize the hot air flow, the supply channel is connected to other consumer sources by a branch pipe, the z. H. for heating cabin spaces or for preventing ice build-up on aircraft components, especially window panes, although it is known per se, serve the exhaust gases of the aircraft engine using venturi tubes to heat cabin spaces to use, just as it is no longer new, -to prevent ice accumulation, all Window panes to heat them using the Auspult # Z:, sc.

In der beiliegenden Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the accompanying drawing.
