Description
(第1実施形態)
ロータ14の回転数=ギア比1×GT回転数+ギア比2×MG回転数
図11はこの発明の第2実施形態に係るマルチコプタ10の減速機構22を模式的に示す、図4と同様の説明図である。
図12はこの発明の第3実施形態に係るマルチコプタ10の減速機構を模式的に示す、図4と同様の説明図である。
図13はこの発明の第4実施形態に係るマルチコプタ10の減速機構を模式的に示す、図4と同様の説明図である。
させるように構成したので、出力に比して重量を低減させることができ、航続距離を増加させて燃費性能を向上させることができる。尚、残余の構成と効果は第1実施形態と異ならない。
図14はこの発明の第5実施形態に係るマルチコプタ10の減速機構を模式的に示す、図4と同様の説明図である。
