Abstract
An aircraft includes a first propulsion unit, a second propulsion, and a controller configured to increase thrust output in one of the first propulsion unit or the second propulsion unit in response to a detected thrust reduction from the other of the first propulsion unit. Each of the first propulsion unit and the second propulsion unit include a rotor driven by a gas turbine engine with a drive shaft, an output shaft coupled between the drive shaft and the driven rotor and a mechanical coupler for decoupling the output shaft from the drive shaft.
