Description
こうすることで、航空機の着陸前に予め、ドライバを通じて電動モータに給電を行い、作動油を加熱することで、油圧アクチュエータを実際に動作させる航空機の着陸時には、作動油の温度が所定温度(下限温度)よりも高くなって、EHAシステムを確実に動作させることが可能になる。その結果、脚揚降装置の信頼性が確保される。
この構成では、航空機の飛行中に、作動油の温度を常時、所定温度よりも高い温度に維持するのではなく、航空機の着陸直前に昇温するため、航空機の燃費向上に有利になる。また、前述の通り、電動モータとドライバとの双方の廃熱を利用することで、作動油の昇温時間の短縮が図られ、航空機の着陸前に、短時間で、作動油の昇温が完了する。
つまり、前記ドライバは、前記作動油の温度を高めるときに、前記電動モータが無回転となるように、前記電動モータに給電する、としてもよい。
また、前記ドライバは、前記作動油の温度を高めるときに、前記油圧ポンプの最小駆動トルク以下となるように、前記電動モータに給電する、としてもよい。
これらの場合は、油圧ポンプが駆動しないため、作動油が油圧回路内で流れない状態で作動油の昇温が行われる。
とにより、油圧ポンプ5を駆動してもよい。この場合は、図1に実線の矢印で示すように、油圧ポンプ5の第1ポート51から吐出された作動油は、電磁弁411を介してリザーバ46に至り、その後、リザーバ46から排出された作動油は、電動モータ6の熱交換器62を介して油圧ポンプ5の第2ポート52へと戻るようになる。こうして、作動油が油圧回路4内を循環しながら、電動モータ6及びドライバ61の廃熱により作動油が昇温するようになる。作動油の昇温時の動作は、作動油の昇温効率、つまり消費エネルギ量と作動油の温度上昇量(又は上昇率)との関係等を考慮して、最適な動作を適宜採用すればよい。その場合に、作動油の循環及び非循環を、昇温プロセスの途中で切り替えるようにしてもよい。
