DUAL-FLOW TURBINE ENGINE HAVING A DECOUPLING DEVICE

摘要

A dual-flow turbine engine including: a fan rotatably mounted on a fan shaft and a stationary structural element, the fan shaft and the structural element being connected to one another at an upstream bearing and at a downstream bearing via an upstream bearing bracket and a downstream bearing bracket, respectively; and a decoupling device surrounding the fan shaft, and including a set of attachment screws joining the downstream bearing bracket to the structural element and a set of fusible screws joining the upstream bearing bracket to the downstream bearing bracket. At least some of the fusible screws are arranged between at least some of the attachment screws over a single circumference surrounding the fan shaft.
