Abstract
A gas turbine engine comprises an engine core, a tie bolt, and a fail-safe system. The engine core includes a compressor, a turbine, and a shaft that couples the compressor with the turbine for rotation with the turbine about an axis. The tie bolt locates axially the compressor relative to the turbine. The fail-safe system is configured to transmit torque from the turbine to the compressor through the tie bolt in response to a shaft disconnect event.
