Aircraft surface humidity online monitoring sensing probe

Abstract

The invention belongs to the field of aircraft structure corrosion environment element monitoring, and particularly relates to an aircraft surface humidity online monitoring sensing probe. The probe comprises a first line electrode, a second line electrode and an insulating carrier plate, the first line electrode and the second line electrode are made of the same material and are arranged on the carrier plate in parallel, and the distance between the first line electrode and the second line electrode is smaller than the line width of the first line electrode and the line width of the second line electrode. The probe monitors the impedance between the electrodes, can quickly reflect whether a liquid film or moisture exists on the surface of a structure or not, is light in weight and small in size, can be directly attached to the surface of an airplane structure for in-situ monitoring, does not damage the original structure, and does not influence the weight and aerodynamic configurationof the airplane.

Description

technical field [0001] The invention belongs to the field of monitoring of aircraft structure corrosion environment elements, and in particular relates to an on-line monitoring sensor probe for aircraft surface humidity. Background technique [0002] When the aircraft is used in coastal areas, it will be subjected to extreme harsh marine environments such as high and low temperature, humidity, salt spray, light, chemical pollution, rain, snow, fog, and seawater splashing, which will easily cause damage to its body structure, systems, electronic equipment and Corrosion of accessories, especially in enclosed areas, corners, and depressions of the aircraft structure, where water is prone to accumulate, forming an extremely harsh corrosion environment, which seriously affects the structural integrity and functionality of the aircraft. The corrosion maintenance of traditional aircraft often adopts the method of regular maintenance. It is mainly based on the use experience to form...
