Aircraft conduit monitoring system and method

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...
