Description
スタータモードにおいて、外部の電源または航空機搭載のAPU(補助動力源)等である電源35からの電力を調整して回転機26に供給し、発電モードにおいて、回転機からの発電電力を調整して外部の電気負荷36に供給する。スタータ制御回路63は、高圧軸回転センサ65から入力される高圧軸回転速度に基づき、モータ制御回路62を制御するとともに、無段変速機25の制御器50を制御して、スタートモードで無段変速機25の減速比を最大値に固定させる。モータ制御回路62は、スタータモードで、予め設定された回転数上昇パターンで回転機26の回転速度を上昇させることにより、エンジン10を起動する。
a)スタータモードにおいて、図2のスタータ制御回路63からの指令により、モータ制御回路62が作動して、回転機26をモーターとして作動させ、HP軸7を駆動し始める。モーター回転とともに、図6に示すHP軸回転数Aも上昇し、エンジンは自立運転を始める。
(1)航空機のエンジン・スタータと発電機を兼用する始動発電装置1であって、図2に示したスタータと発電機を兼ねる回転機26、変速機(例えばトラクションドライブ無段変速機)25、高圧側クラッチ27および低圧側クラッチ28を備え、エンジン10の高圧系と低圧系のそれぞれと結合し、エンジン・スタート時はモータ26が直接高圧系を駆動し、エンジン10が自立運転に入ったあとはエンジン10の低圧系が無段変速機25を駆動し、この無段変速機25がエンジン10からの入力回転数にかかわらず発電機26を一定回転速度で駆動する。
(4)スタート時は常にエンジン低圧軸8の回転速度が装置1側よりも遅く、エンジン自立後は常にエンジン高圧軸7が装置1側よりも速い回転速度となるように、第1ギヤ列30および第2ギヤ列31の各ギヤ比を選定して各要素間を繋ぐ(無段変速機25はLoモード)。これにより、スタート時はファン9を回転させず、エンジン自立後はコア(高圧軸7)に影響を及ぼさない。
(7)無段変速機25と回転機26は別々のハウジングH25,H26に収納してもよい(図7)。
(8)非常時は必ず無段変速機25がLoモードとなるように制御する。
また、エンジンスタート時は回転機26が高圧軸21のみを駆動してエンジン10をスタートさせ、このとき、低圧側クラッチ28は空転するので、低圧軸22は駆動されない。したがって、低圧軸22に連結される巨大なファン9(図1)のような負荷による大きな抵抗の発生を避けることができるので、スタート時の所要動力が低減される。
上記を通じ航空機の電動化を促進できる。
