DUAL-FLOW TURBINE ENGINE HAVING A DECOUPLING DEVICE

摘要

The invention relates to a dual-flow turbine engine including a fan rotatably mounted on a fan shaft (1) and a stationary structural element (2), said fan shaft (1) and said structural element (2) being connected to one another at an upstream bearing (5) and at a downstream bearing (6) via an upstream bearing bracket (4) and a downstream bearing bracket (6), respectively, and a decoupling device (3) surrounding said fan shaft (1) and including a set of attachment screws joining the downstream bearing bracket (6) to said structural element (2), and a set of fusible screws joining the upstream bearing bracket (4) to said downstream bearing bracket (6). At least some of said fusible screws of the device are arranged between at least some of said attachment screws over a single circumference surrounding the fan shaft.
