In a turbomachine whose speed of rotation is controlled by means of a throttle control lever acting via an electronic control circuit, a system is provided to provide protection against excess speed, the system comprising means for limiting the fuel feed of the turbomachine to a predetermined fixed flow rate Wps when the speed of rotation exceeds an authorized maximum speed, means for maintaining said fuel feed at said predetermined fixed flow rate while the speed of rotation drops below the authorized maximum speed, and means for reducing said fuel speed to a flow rate Wr corresponding to an idling speed when the throttle control lever issues an idling control to the turbomachine via the electronic control circuit.
A protection system for providing a turbomachine with protection against excess speed, in which machine a speed of rotation is controlled by a throttle control lever acting via an electronic control circuit, said system comprising:
