摘要:
An apparatus for recovering kinetic energy released during and aircraft landing after ground contact, for ground and/or flight operation, comprising at least one energy converter for conversion of the kinetic energy into another energy form, where the energy converter is located in the area of the nose landing gear and/or in the area of the main landing gear of the aircraft. At least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy. The apparatus has a high degree of multiple utilization and enables, for example, maneuvering of a landed aircraft on the taxiway independently of the engines, where the aircraft is substantially moved with the braking energy recovered during the landing process. Since the main engines are no longer required for maneuvering, there is a considerable potential for saving energy and the use of motor-operated tow vehicles is eliminated.

A system for flushing a vacuum toilet in an aircraft, with a bowl drain for removing toilet waste water from a bowl, a drain line, a bypass flow line for feeding-in air, a drainage valve and a waste water line. The bowl drain and the bypass flow line are connectable to the drain line, and the drainage valve on the input side is connectable to the drain line, and on the output side is connectable to a waste water line. In an implementation of the vacuum toilet as a vacuum urinal, the system may provide either water flushing or waterless flushing.
摘要:
The invention relates to an odor seal for a vacuum toilet drain system whose cross section in the state of no throughflow tapers off in such a way in the downstream direction that the interior walls on the downstream end of the odor seal rest against each other so that the odor seal in a downstream direction allows throughflow while in the opposite direction it blocks throughflow, wherein the downstream end of the odor seal is closed in the state of throughflow and no throughflow of the odor seal. Furthermore, the invention relates to a drainage device comprising such an odor seal and a sieve which is arranged upstream of the odor seal. Moreover, the invention relates to a vacuum toilet system for an aircraft, comprising such an odor seal or a drainage device.
摘要:
A vacuum toilet and a method for operating a vacuum toilet, wherein generating negative pressure to remove solids by suction is also used for generating a desired flushing medium flow. To this effect, if necessary, guiding devices are used which influence a flow upstream of a nozzle outlet and downstream of a nozzle outlet such that flow optimization of the flushing medium can be carried out.

An inspection device is provided to monitor hygienic conditions of a space unit for a vehicle. The vehicle includes, but is not limited to, an inspection device, the use of an inspection device, and a method to assure hygienic conditions in a vehicle. In order to optimize assuring hygienic conditions in interior spaces on board a vehicle an inspection device is provided that includes, but is not limited to, an optical detection device. The optical detection device generates electromagnetic radiation to irradiate a surface to be cleaned, and renders visible soiling that, in visible light, is invisible to the human eye. The optical detection device is permanently installable on an interior lining.

A draining system having an odor seal for a vacuum toilet drain system in which a flexible hose acts as an odor seal. As a result of the flexible hose, propagation of odors can be prevented when the hose collapses flat, for example as a result of its intrinsic weight, and consequently there is no longer a flow-through cross section, wherein, however, drainage of liquids remains possible.

At least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy from a landing aircraft. The system has a high degree of multiple utilisation and enables, for example, manoeuvring of a landed aircraft on the taxiway independently of the engines, where the aircraft is substantially moved with the braking energy recovered during the landing process. As a result of the main engines no longer being required for manoeuvring, there is a considerable potential for saving energy and the use of motor-operated tow vehicles is eliminated. The apparatus also contributes in the sense of a “green” and economical technology to saving aircraft fuel and better fulfils future requirements of airports, particularly with a view to noise and pollutant reduction. In addition, the invention has as its subject matter a method for recovering braking energy of an aircraft.
摘要:
A system for flushing a vacuum toilet, includes a drain that is connected to a drain conduit, which vacuum toilet is connectable to a vacuum system by way of a suction valve. With the use of a combined valve including, for example, a flow-optimised intermediate storage device, inflow nozzle, bypass conduit with silencer and hose odor seal, the flow noises at the urinal bowl drain, urinal bowl overflow and upper end of the bypass conduit can be effectively suppressed. With the combination disc valve or the shut-off valve and suction valve, during the suction process the air stream is only drawn through the bypass conduit with a special odor seal and silencer.
