Turboshaft engine e.g. turbojet, for aircraft, has cylindrical sleeve whose downstream ends include axial support units on which pivot is supported due to differential thermal dilations in direction opposed to upstream ends of sleeve

摘要

The engine has a low pressure module and a high pressure module, where the low pressure module comprises a compressor and a turbine whose rotors are connected by a drive shaft. The drive shaft extends inside a cylindrical sleeve (26') whose upstream ends (28) and downstream ends (30') are connected to a pivot (20). The downstream ends of the sleeve include axial support units or an external edge on which the pivot is supported due to differential thermal dilations in a direction opposed to the upstream ends of the sleeve for applying tractive force to the sleeve.
