Claims (9)
- シャフトを駆動し、ステータ内で回転可能であるロータを備えるタービンの回転速度を、前記シャフトが破損した場合に低下させるための、ガスタービンエンジンにおける方法であって、ロータの下流にあるステータの面上の点で温度を測定し、測定信号をロータの減速を制御する制御手段に伝達することからなり、温度が閾値に達すると前記制御手段がロータの減速を制御するよう設計されている、方法。
- 制御手段が、エンジン燃焼室への燃料供給のための制御装置である、請求項1に記載の方法。
- 少なくとも1つの熱電対センサを用いて温度が測定される、請求項1または2に記載の方法。
- 複数の熱電対センサを用いて、タービンの軸の周囲に分散する複数の点で温度が測定される、請求項3に記載の方法。
- 温度閾値は、エンジンの作動時に達することが可能である最高温度を超えている、請求項1から4のいずれか一項に記載の方法。
- ガスタービンエンジンにおける、シャフトを駆動しステータに対して回転可能であり、リムが備えられるタービンディスクを有するロータを備えるタービンの回転速度を、前記タービンシャフトが破損した場合に低減させるための装置であって、ロータの近くに配置されるとともにエンジン燃料制御部材に接続されてステータの温度を検知する温度センサを備え、前記部材は、センサにより出された信号が規定の閾値を超えている場合に燃料の供給を停止するよう設計されており、熱電対プローブはステータにてリムのすぐ下流に配置されている、装置。
- センサが熱電対式である、請求項6に記載の装置。
- 複数の熱電対プローブを備える、請求項7に記載の装置。
