System for mitigating overspeeding of a turbine engine |
摘要 |
<p>The system (301) for mitigating an overspeeding condition of a turbine engine (113) can include a sensor (303) for measuring an actual speed (Ng) of a gas generator turbine (127) of the turbine engine and a processor (305) for deriving a delta (407), the delta being a comparison between the actual speed (Ng) of the gas generator turbine and a predicted gas generator turbine speed (405). The system is configured for detecting the overspeeding condition when delta (407) is higher than a predetermined threshold. A method of detecting an overspeeding condition during operation of a turbine engine (113) can include measuring an actual speed of a gas generator turbine (Ng), then evaluating a delta (407) between the actual speed of the gas generator turbine and a predicted speed (405) of the gas generator turbine, then comparing the delta (407) to a threshold value.</p> |
