Description
前述の通り、航空機の脚の降着装置には、ギヤアクチュエータの他に、ドアアクチュエータ及びダウンロックリリースアクチュエータを含んでおり、これらのアクチュエータは、脚の揚げ降ろしの際には、順に作動する。そこで、これら複数のアクチュエータに対して作動油を供給する油圧供給源や油圧マニホールドを、共用化することが考えられる。
21 片ロッドシリンダ(ギヤアクチュエータ)
22 片ロッドシリンダ(ドアアクチュエータ)
3 油圧供給源
31 第1油圧供給源
32 第2油圧供給源
33 油圧ポンプ
34 電動モータ
48 油圧マニホールド

51 シリンダ(シリンダ本体)
52 ピストンロッド(シリンダ本体)
53 ピストンヘッド(シリンダ本体)
54 可動端
55 シリンダエンド
56 固定端
81 リザーバ
