Abstract

The invention provides an anti-icing sensor, and belongs to the technical field of detection equipment. The anti-icing sensor specifically comprises a sensitive element, a mounting base and a sensor shell connected with the mounting base. The side, far away from the mounting base, of the sensor shell is provided with a temperature measuring end, and the temperature measuring end is provided with an anti-icing structure. The sensitive element is connected with the sensor shell and located on the leeward side of the temperature measuring end. The anti-icing structure is of a wedge-shaped structure, the wedge-shaped structure comprises a windward end and a leeward end, and the cross sections, parallel to the airflow direction, of the windward end and the leeward end are isosceles triangles. A first vertex angle of the isosceles triangle of the windward end faces the incoming flow direction, a second vertex angle of the isosceles triangle of the leeward end is away from the incoming flow direction, and the first vertex angle is larger than the second vertex angle. According to the processing scheme, the situation that the temperature measuring function of the sensor fails due to freezing of the temperature measuring end can be effectively avoided, and the testing stability is improved.

Description

technical field [0001] The present application relates to the technical field of detection equipment, in particular to an anti-icing sensor. Background technique [0002] According to different anti-icing methods, temperature sensors can be divided into bleed air anti-icing, electric anti-icing, mechanical anti-icing and so on. At present, the bleed air anti-icing temperature sensor mainly adopts air heat anti-icing, and the anti-icing hot air is mostly bleed air from the engine compressor, and the hot air is regulated and controlled by the anti-icing valve and enters the front edge of the engine inlet or the temperature measuring end of the sensor to achieve anti-icing. The purpose of the ice, but the processing of the inner cavity structure of the bleed air sensor is complicated, and the relevant structural cooperation is required, the weight is greatly increased, and the accuracy is easily disturbed by the discharged hot gas. The electric heating temperature sensor mainl...
