DEVICE FOR STIFFING A STATUS OF A FLOW MACHINE AND THEIR APPLICATION IN AIRCRAFT ENGINES

摘要

The turbomachine has a rotor placed internally to a stator (2) having internal ferrules (20), a single-piece external ferrule (21) and a fixed blade stage. The stator has profiled members forming stiffeners (23) placed on a stage while being distributed at periphery of the stage and individually placed between two consecutive blades (22). The stiffeners are fixed to the ferrules (21) to increase axial and radial stiffness of the stator in a normal operation of the turbomachine and to enable the internal ferrules to have a limited displacement during the normal functioning of the turbomachine. An independent claim is also included for an aircraft engine comprising a decoupling device.
