Abstract: An aircraft galley with a main body formed with walls and a cover plate which form a stowage space for catering containers and have trolley berths arranged next to one another. The stowage space is configured as a cooling chamber, and at least one cooling apparatus introduces cooling air into the stowage space via cooling air outlets in the upper region of the catering containers and extracts heated cooling air via return air inlets in the lower region of the catering containers. A drip pan is substantially perpendicularly below the cooling apparatus, which drip pan has, in the edge region of at least one side, a transition portion to a seal, and a collecting portion. This advantageously achieves a situation where the condensed water is collected and discharged, and accumulations of water are avoided on the floor of the galley in the working area of the flight attendants.

Abstract: A waterless vacuum toilet system for an aircraft includes a toilet bowl connected via a suction valve and a waste collection pipe to a waste collection tank. Waste-contacting surfaces that come into contact with urine and fecal waste are coated with an adhesion-inhibiting or adhesion-reducing nanocoating. The adhesion of waste is significantly reduced, and the need for flushing water is completely eliminated. Instead, an air jet arrangement preferably including an annular ring nozzle or annular air gap directs an airflow into the toilet bowl and along the nanocoated waste-contacting surface thereof, to “air flush” the waste material from these surfaces. The flushing airflow may be induced through the air jet arrangement into the toilet bowl by the suction applied through the suction valve. The “air flushed” toilet system substantially reduces the total system weight and eliminates the need for toilet flushing water to be carried in the aircraft.

Abstract: A water supply system, particularly for an aircraft such as a passenger aircraft, includes a disinfecting unit with an electrolysis cell connected in series with a water storage tank including a water distribution pipe system and a circulating pump. A bypass pipe with a valve permits connecting the electrolysis cell to the distribution system or bypassing the electrolysis cell. The electrolysis cell disinfects the water by anodic oxidation. A salt solution container may be connected to the electrolysis cell to enhance the anodic oxidation. The pump circulates the disinfected water through the tank and/or through the entire system, whereby the water supply is disinfected and the disinfected water in turn disinfects the entire system.

Abstract: A toilet system, especially for passenger transport vehicles, includes a toilet bowl connected via a suction valve and a waste collection pipe to a waste collection tank. Waste-contacting surfaces of the toilet system that come into contact with urine and fecal waste are coated with an adhesion-inhibiting or adhesion-reducing nanocoating. Thereby, the adhesion of waste to the toilet bowl and other components is significantly reduced, and the total flushing water demand can be substantially reduced or, preferably completely eliminated. An airflow flowing into the toilet bowl, induced by the vacuum suction through the suction valve, is sufficient to “flush” the waste material from the nanocoated waste-contacting surfaces. The toilet system provides a substantial reduction in the total system weight and in the required quantity of flushing water that must be carried in the vehicle, and thus makes the toilet system particularly applicable for passenger transport vehicles such as aircraft.
