Problems solved by technology

[0002] In order to test the dynamic stress, wall temperature, cavity temperature and other parameters of the aero-engine rotor components, it is necessary to carry out test leads inside the engine rotor. The lead wires are fixed on the rotor journal, but in order to adapt to the high temperature and high pressure working environment of the engine, more and more rotor journals are made of titanium alloy materials, and the rotor journals made of titanium alloy materials should not be welded. Fix the test leads. At present, the rotor journals made of titanium alloy materials are mostly fixed by gluing the test leads. This method of fixing the test leads can well adapt to low temperature and low speed conditions. conditions, but it is difficult to meet the working conditions of high temperature and high speed, and it is very easy for the test lead to fall off under the working conditions of high temperature and high speed

Abstract

The application belongs to the technical field of engine rotor testing, and particularly relates to an engine rotor testing lead structure which comprises a rotor journal, an outer lead cylinder arranged on the inner side of the rotor journal along the axial direction and connected with the rotor journal, an the inner lead cylinder arranged on the inner side of the outer lead cylinder in the axialdirection and connected with the outer lead cylinder, and a plurality of test leads. A plurality of lead channels extending in the axial direction are formed between the inner lead cylinder and the outer lead cylinder; and each test lead correspondingly penetrates through one lead channel.
