運用LT (アポロ12号の話) ロケットがカミナリに打たれるとどうなるか 2019/12/17 (C) Copyright 1996-2019
SAKURA Internet Inc さくらインターネット研究所 所長 鷲北 賢さくらインターネット株式会社
2.
ライトニングトーク なので カミナリの話をします 2
3.
アポロ12号 • 人類2回目の月面着陸 • あんまり注目されてない •
オモシロエピソード満載 • 紹介し始めると10時間ぐらいかかる • 今回は打ち上げのときのトラブルの話 3
4.
アポロ12号打ち上げ • 1969年11月14日 • 雷雨の日に打ち上げ強行 ─初めての雷雨打ち上げだった ─ニクソン大統領が見物に来ていた ─延期できなかった 具体的にどんな危険があるか 分かっていなかった 4
5.
雨雲を突き抜けて打ち上げたら… • 打ち上げ36.5秒後、雷が直撃 ─ 排気ガスを伝わって電流が流れてしまった •
司令船の燃料電池のブレーカーが過負荷に ─ 遮断回路が働いて一斉にダウン ─ コンピュータのタイマとプラットフォームが停止 ─ 警告ランプが一斉に点灯 (クリスマスツリー効果) • サターンVロケットは正常に飛行 ─ ロケットの制御コンピュータは別の場所にあって 無事 5
6.
宇宙飛行士の置かれた状況 • 背中には2000トン以上の燃料が燃焼中 ─ 1段目切り離しまで2分間もない(2分30秒で 燃え尽きる) ─
アボート・レバーを引けば脱出できるが、何百億 ドルの資産が吹き飛ぶ ─ コンパネは真っ赤で、訳が分からない • 管制室ではテレメトリが読めない状態 ─ ダウンリンクが死んで画面が壊れた状態に ─ かなり絶望的な状況 6
7.
テレメトリの異常 7From the Earth
to the Moon, HBO(TV) の再現シーンより
8.
現場に天才がいた • 画面の崩れ方を見て、思い出した ─ 昔受けた訓練と同じ壊れ方をしている ─
あの時の直し方を試すことに • 「SCEをAUXに」と指示 ─ EECOMの指示をFD(現場責任者)が理解できない ─ が、CAPCOMに伝えるように指示 ─ CAPCOMも理解できないが、そのまま指示 ─ CDR(宇宙船船長)は「NCE??ってなんだ?」 ─ LMP(着陸船パイロット)が気づいて対処 • 落雷後、1分間で対処法を指示 • 指示後、11秒で復帰 8
9.
その後のアポロ12号 • 無事に打ち上げ成功 • 地球周回軌道でコンピュータをリセット ─タイマは予備があったのでそちらで合わせ直し ─プラットフォームは星を見て測り直し •
ミッションルールを変更 ─雷雨のときは延期することにした 9
10.
監視とは… 「監視とはスキルであり、開発チーム内の全 員がある程度のレベルに至っておくべき」 Mike Julian,松浦隼人 訳,入門
監視 • 真理だが、「ある程度」ってどの程度? • システムが複雑すぎて「全員」は不可能 • これは1分間で解決できる問題だろうか • どれほどの訓練でこの境地に達するのか? 10
11.
アポロ11号が チートシートで 救われた話 は、また今度 11
