| 20090255277 | OPTIMIZED DEFROSTING REGULATION OF PARALLEL ARRANGED FRESH AIR OUTLETS OF AIR CONDITIONERS - An arrangement is provided for de-icing pipeline connections of an aircraft, which are connected to all fresh air outlets of an air conditioner, whose construction includes, but is not limited to the functions of multiple turbines and heat exchangers, having a first pipeline, which is connected to a first turbine, and a second pipeline, which is connected to a second turbine, the two pipelines, which are each connected downstream from the two turbines and to which process air is fed at the turbine outlets, being connected at the pipe ends and being continued using a third pipeline. The arrangement is characterized in that a first hot air source is fed hot fresh air from a bleed air system of the aircraft and is connected at its outlet to a fourth pipeline, into which temperature-reduced fresh air is fed from the hot air source. The fourth pipeline is connected at its pipe end to two further valve-regulated pipelines, of which a fifth or a sixth pipeline is connected to the first or the second pipeline, and through which temperature-reduced fresh air is transported and fed valve-regulated to the first and/or second pipeline. | 10-15-2009 |

| 20110247432 | Aircraft Conduit Monitoring System And Method - The invention relates to an aircraft conduit monitoring system comprising a conduit that conducts gas from a source to a point of application. A flow sensing device and a pressure sensing device are provided within the conduit. At least one set value of a gas mass flow rate and at least one set value of a pressure are sensed in a learning mode of operation. Said set values are compared with sensed actual values in the normal mode of operation. A gas volume flow rate can also be sensed and processed instead of a gas mass flow rate. | 10-13-2011 |

| 20130035027 | MIXER ASSEMBLY FOR AN AIRCRAFT AIR CONDITIONING SYSTEM - A mixer for an aircraft air conditioning system has first and second fresh air lines and first and second recirculation air lines. A first premixer is connected to the first fresh air line and the first recirculation air line, to mix the fresh air with the recirculation air thereof. A second premixer is connected to the second fresh air line and the second recirculation air line, to mix the fresh air with the recirculation air thereof. A main mixer is connected by a first premixed air line to the first premixer and by a second premixed air line to the second premixer. The main mixer is adapted to be supplied through the first premixed air line and the second premixed air line exclusively with premixed air from the first and/or the second premixer. | 02-07-2013 |
| 20130130607 | MIXING DEVICE FOR AN AIRCRAFT AIR CONDITIONING SYSTEM - A mixing device for an aircraft air conditioning system includes a plurality of cold-air supply lines, which are devised to supply cold air to the mixing device. A plurality of warm-air supply lines is further provided, which are devised to supply warm air to the mixing device. A first premixing chamber is connected to the cold-air supply lines and devised to mix the cold air that is fed through the cold-air supply lines into the first premixing chamber. A second premixing chamber is connected to the warm-air supply lines and devised to mix the warm air that is fed through the warm-air supply lines into the second premixing chamber. Finally, a main mixing chamber is connected to the first and the second premixing chambers and devised to mix the cold air premixed in the first premixing chamber with the warm air premixed in the second premixing chamber. | 05-23-2013 |
| 20130291651 | METHOD AND DEVICE FOR DETERMINING AN AIR MASS FLOW FLOWING THROUGH A RAM AIR CHANNEL - A method and a device determines an air mass flow flowing through a ram air channel having disposed therein a feed device adapted in a first operating state of the ram air channel to feed air through the ram air channel and further adapted in a second operating state of the ram air channel to be set in rotation by an air mass flow flowing through the ram air channel. The method includes the step of detecting an actual operational characteristic of the feed device that is characteristic of the air mass flow flowing through the ram air channel in the second operating state of the ram air channel as well as the step of determining the air mass flow flowing through the ram air channel on the basis of the detected actual operational characteristic of the feed device. | 11-07-2013 |
| 20130295831 | METHOD FOR CONTROLLING AN AIRCRAFT AIR CONDITIONING SYSTEM DURING MAINTENANCE - In a method for controlling an aircraft air conditioning system, during normal operation of the aircraft, the supply of conditioned air from the aircraft air conditioning system to an aircraft region to be air conditioned is controlled such that the conditioned air is evenly distributed in the aircraft region to be air conditioned. During a predetermined operational phase of the aircraft, the supply of conditioned air from the aircraft air conditioning system to the aircraft region to be air conditioned is controlled such that the conditioned air is distributed only in a selected portion of the aircraft region to be air conditioned. | 11-07-2013 |
