Flexible retention assembly for turbomachine rotating part burst test bench

Abstract

The invention relates to a flexible retention assembly (4) for a test bench (1) for bursting a rotating part of a turbomachine (9), said test bench (1) comprising a hollow cylindrical wall defining an internal test chamber (10) having a first hollow cylindrical volume (V1) extending along a longitudinal axis (L), a drive shaft (2) mounted for rotation about said longitudinal axis (L) and on which said rotating part (9) is intended to be fixed, said test bench (1) further comprising means for retaining fragments from said rotating part (9), said fragment retention means comprising: a rigid retention assembly (3) intended to be housed in said first hollow internal volume (V1) and comprising at least one rigid retention element (30) of hollow cylindrical shape defining a second hollow cylindrical internal volume (V2) intended to extend along said longitudinal axis (L); said flexible retention assembly (4), said flexible retention assembly (4) comprising at least one ring flexible retention (40, 40’, 40’’, 40’’’) of hollow cylindrical shape extending around a longitudinal axis (X) and defining a third hollow cylindrical interior volume (V3), said at least one flexible retention ring (40, 40’, 40’’, 40’’’) comprising at least one shear-thickening fluid (6).
