  • Method of measuring loadings in joins in a high-temperature environment and instrumented shaft for implementation, in particular for rear attachment of aircraft turbojet
    Patent number: 9151697
    Abstract: The invention aims to produce an instrumentation making it possible to measure the loadings which pass through mechanical joins between two mechanical structures, so as to best evaluate the dimensions and masses without impairing their mechanical properties of a secure transfer of load. To this end, the invention proposes introducing into the zones of transit of the loadings an instrumented component of the form that favors the measurement of shear and its installation. In one embodiment, a zone of transit of loadings consists of an instrumentalized hollow shaft which takes the form of a cylinder (1) able to be introduced into collinear openings (30) in the fittings (20, 25, 26). It comprises a longitudinal housing (10) into which is introduced an insert (2) composed of a central prop (21) in tight contact with the internal wall (1i) of the shaft (1) and connected, on each side, to a flyweight (31, 32) also in tight contact, by way of multiple tabs (41 to 44) away from contact with said internal wall (1i).
