Abstract
Description
Die Wirtschaftlichkeit von Verkehrsflugzeugen wird hauptsäch lich durch den Anteil der Nutzlast am Gesamtgewicht bestimmt. Deshalb strebt man an, das Leergewicht und das Gewicht von Treibstoff, Betriebsmaterial und Versorgungsgütern klein zu halten. Ein Weg dazu ist, die Menge des Trinkwassers zu ver ringern, das für die Versorgung der Passagiere während des Fluges mitgeführt werden muß.The economic viability of commercial aircraft becomes main Lich determined by the share of the payload in the total weight. Therefore one strives for the empty weight and the weight of Fuel, supplies and supplies too small hold. One way to do this is to measure the amount of drinking water wrestle for the supply of passengers during the Flight must be carried.
Da der Wasserbedarf an Bord im wesentlichen durch die Anzahl der Passagiere und die Flugdauer bestimmt wird, kann der Vor rat nur verringert werden, wenn man das Wasser mehrfach nutzt. Für folgende Zwecke wird Wasser benötigt:Since the water requirement on board is essentially determined by the number the passenger and the flight duration is determined, the pre advice can only be reduced if the water is used several times. Water is required for the following purposes:
- - Versorgung der Bordküchen,- supply of the galley,
- - Spülung der Toilettenbecken,- flushing the toilet bowl,
- - Händewaschen in den Toiletten.- Washing hands in the toilets.
Die anfallenden Abwässer aus den Bordküchen und den Handwasch becken werden bei dem jetzt üblichen Wassersystem durch Drain masten direkt über Bord geleitet; die aus den Toiletten stam menden Abwässer werden in einem Fäkalientank gesammelt und je weils bei Aufenthalten an Boden entsorgt (Abb. 1).The resulting wastewater from the galley and the hand-washing basin are routed directly overboard through drain masts in the now common water system; the wastewater from the toilets is collected in a holding tank and disposed of on the ground during stays ( Fig. 1).
Eine Verkleinerung des Wasservorrates ist nur dann möglich, wenn das Wasser mehrfach verwendet werden kann. Das erfordert eine Aufbereitung des Abwassers. Obwohl Verfahren dazu bekannt sind (Raumfahrt), kommt eine Aufbereitung von Abwässern zu Trinkwasser in Verkehrsflugzeugen aus psychologischen und technischen Gründen nicht in Frage. Deshalb ergibt sich als praktisch realisierbare Lösung, Frischwasser zunächst zum Händewaschen und dann zum Spülen der Becken in den Toiletten zu verwenden (Abb. 2). Damit ist eine Reduzierung des Startgewichtes eines Verkehrsflugzeuges um die Menge des Toilettenspülwasser möglich (ca. 300 kp bei einem Langstreckenflugzeug).The water supply can only be reduced if the water can be used several times. This requires treatment of the wastewater. Although methods for this are known (space travel), treatment of waste water into drinking water in commercial aircraft is out of the question for psychological and technical reasons. Therefore, a practically feasible solution is to first use fresh water to wash hands and then to flush the basins in the toilets ( Fig. 2). This makes it possible to reduce the take-off weight of a commercial aircraft by the amount of toilet flushing water (approx. 300 kp for a long-haul aircraft).
Im Gegensatz zur heute üblichen Arbeitsweise gelangt bei dem vorgeschlagenen System die gesamte zum Händewaschen benötigte Wassermenge in den Fäkalientank (Abb. 3) und muß bis zum Ziel ort transportiert werden. Diese Transportleistung kann ent fallen, wenn die aus den Handwaschbecken und den Bordküchen stammenden Abwässer während des Fluges aus dem Fäkalientank entfernt und laufend über einen Drainmast nach außen abgeführt werden (Verringerung des mittleren Transportgewichtes). Aus Gründen des Systemvereinfachung werden auch die Bordküchen an das Abwassersystem der Toiletten angeschlossen.In contrast to the usual way of working today, with the proposed system the entire amount of water required for washing hands goes into the holding tank ( Fig. 3) and has to be transported to the destination. This transport performance can be eliminated if the waste water from the hand wash basin and the galley is removed from the waste-holding tank during the flight and continuously discharged to the outside via a drain mast (reduction in the average transport weight). To simplify the system, the galley kitchens are also connected to the toilet sewage system.
