Embodiment Construction

[0035] Figure 6 An air duct system is shown comprising a first duct 2 , a second duct 3 and a third duct arranged in succession. Air flow 1 is fed into a first duct 2 . Air flow 1 may be hot bleed air from the propulsion unit. The third duct 4 comprises an opening 5 through which air exits the duct. The openings 5 ​​may be located transverse to the direction of the air flow, and / or in the same direction as the air flow. Alternatively, only one opening may be provided. The opening 5 may be located in the wing of the aircraft, for example, for deicing the wing.

[0036] The air flow 1 can also be supplied by an air conditioning unit and the opening 5 can be located in the passenger cabin of the aircraft.

[0037] A flow sensing device 7 , an optional temperature sensor 8 and a pressure sensing device 9 are located in the first conduit 2 . An optional temperature sensor 8 is coupled to the flow sensing device 7 . The flow sensing device 7 and the pressure sensing device 9 ...

Abstract

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 desired value of a gas mass flow rate and at least one desired value of a pressure are sensed in a learning mode of operation. Said desired 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.

Description

technical field [0001] The invention relates to an aircraft pipeline monitoring system and method, in particular to an aircraft wing deicing system and an aircraft air conditioning system. Background technique [0002] The aircraft includes a de-icing system that conducts hot bleed air from the propulsion units to the wings, especially the leading edges, during flight. Thus, during flight, the airfoil is maintained at a temperature that ensures that ice does not form on the airfoil. Ice on wings is known to cause aircraft to crash. The use of such de-icing systems is important, especially during landing of the aircraft. If the aircraft is flying at a high altitude, eg 10000 meters, the air has relatively low humidity, but is extremely cold. Thus, the wings of the aircraft are cooled to cryogenic temperatures. During landing, the aircraft enters a layer of moist air. Since the aircraft's wings are still at temperatures significantly below 0°C, when descending below an al...
