Abstract

The invention discloses an airplane electrothermal deicing system optimizing method and belongs to the technical field of airplane ice preventing and removing. The airplane electrothermal deicing system optimizing method comprises the steps that according to set deicing periods and different segmentation methods of a protection area, heating time periods in the deicing periods corresponding to the different segmentation methods are determined; according to flight conditions and given different deicing surface power degrees, a relation curve of deicing power consumption, deicing surface power and heating time is determined; then ice preventing surface power of a continuous heating element is determined; deicing power consumption of periodic heating elements corresponding to the different segmentation methods is determined; deicing surface power of the periodic heating elements corresponding to the different segmentation methods is determined; total system power consumption corresponding to the different segmentation methods is determined; and finally the segmentation method corresponding to the minimum total power consumption is selected. Multi-segment deicing is carried out on an airfoil in the extending direction, the minimum power consumption is determined through the optimizing method, and the deicing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft anti-icing, and in particular relates to an optimization method for an aircraft electrothermal deicing system. Background technique [0002] The icing problem of the aircraft seriously endangers the safety of the aircraft. Ice appears on the surface of the aircraft, hindering the flow of air, increasing friction and reducing lift, especially the ice on the wings has a great impact on the take-off of the aircraft. Ice that accumulates on the tail of an aircraft can upset the balance of the aircraft, in which case the aircraft's anti-icing system plays an important role. [0003] In the prior art, heating is usually used for deicing, for example, an expandable graphite foil heating unit is used for deicing, or other heating elements are used for heating and deicing. Heating by a single heating element consumes a large amount of power. Contents of the invention [0004] In order to solve the ab...
