Abstract

The invention belongs to the technical field of airplane component strength testing, and particularly relates to an airplane component strength testing heating device which comprises: a box body, wherein the box body is provided with an inert gas inlet communicated with the internal space of the box body, an inert gas outlet communicated with the internal space of the box body and a radiation heating window communicated with the internal space of the box body; a graphite heating element which is arranged in the internal space of the box body; and glass which is arranged in the radiation heating window and blocks the radiation heating window, wherein the graphite heating element can radiatively heat the aircraft component through the glass. In addition, the invention relates to an airplane component strength testing heating method implemented based on the airplane component strength testing heating device.

Description

technical field [0001] The application belongs to the technical field of strength testing of aircraft components, and in particular relates to a heating device for strength testing of aircraft components and a method thereof. Background technique [0002] When the aircraft is flying at high speed, the surface is subjected to a large aerodynamic thermal load. When performing strength tests on relevant aircraft components, it needs to be heated to simulate the environment in which the aircraft is flying at high speed. [0003] In some aircraft component strength tests, graphite heating elements are designed for radiation heating. In order to avoid oxidation failure of graphite heating elements at high temperatures, current graphite heating element radiation heaters are mostly set in vacuum tanks when working. This technical solution There are the following defects: [0004] 1) It is difficult to ensure effective vacuum in the vacuum tank, the reliability is poor, and the oper...
