Abstract
A system and method of controlling the acceleration of a load driven by a gas turbine engine detects the existence of an overload condition and reduces an acceleration setpoint when such condition arises.
Claims9
A control for a system including a gas turbine engine having a rotor for driving a load and a controllable clutch mechanism for coupling the rotor to the load, comprising:
- means for sensing an overload condition;
- and
- means responsive to the sensing means for causing the clutch mechanism to change the acceleration of the load without disengaging the clutch.
An overload protection system for a gas turbine engine wherein the gas turbine engine includes a rotor and a combustor, comprising:
- a controllable clutch mechanism for coupling the rotor of the gas turbine engine to an output shaft that drives a load wherein the controllable clutch mechanism is operable under a non-overload condition to maintain the load acceleration at a first level;
- and
- a control including means for sensing fuel flow to the combustor and means responsive to the sensing means for causing the clutch mechanism to change the load acceleration to a second level less than the first level in the event of an overload condition.
