Description
本願は、以下の出願の利益を主張し、これらはすべてその全体が参照により本明細書に組み込まれている:
BATTERY PACK DESIGN WITH THERMAL RUNWAY VENT COVERと題される、Delioussineらによる2019年9月10日出願の米国仮特許出願第62/898,543号;
BATTERY PACK DESIGNと題される、Delioussineらによる2019年4月25日出願の米国仮特許出願第62/838,926号;
HIGH ALTITUDE LONG ENDURANCE(HALO) AIRCRAFTと題される、Sechristらによる2019年4月25日出願の米国仮特許出願第62/838,783号;および
THERMAL CONTROL SYSTEMS AND METHODS FOR HIGH ALTITUDE LONG ENDURANCE AIRCRAFTと題される、Delioussineらによる2019年5月30日出願の米国仮特許出願第62/854,711号。
鋸の角度および軸方向の高さは、切り込み875の下の弱化領域875aのみを残して、離脱排出口カバー885の周りのカバー構造800の全体を通ってチャネル開口部850bを切るように調節され得る。小型卓上鋸は、切り込み線875および/またはチャネル開口部850bを形成するために、適切な深さ位置および対応する角度に設定される。他の既知の切断および切り込み技術、例えば、レーザ、ルーティング、スタンピング、熱切断、穿孔などが用いられてもよい。例えば、排出口からプラグが外れて排出口を開放し、熱暴走の圧力を除去するように、周囲構造から排出口カバーが破壊される場所を決定または制御する弱化領域を形成するために、鋸の切り込みの代わりに、またはそれと共に、ミシン目などが利用され得る。なお別の実施形態において、排出口からプラグが外れて排出口を開放し、熱暴走の圧力を除去するように、周囲構造から排出口カバーが破壊される場所を決定または制御するために、カバー構造は、より弱い領域、例えば、隣接する領域もしくは周囲の領域全体および/または排出口カバーよりも少ない材料または薄い材料、あるいは、隣接する領域もしくは周囲の領域全体よりも、および/または排出口カバーよりも脆い異なる材料を含む領域を有するように製造されてもよい。そのため、圧力リリーフ排出口の破砕可能カバーは、通気口プラグを少なくとも部分的に覆って、通気口カバーに対する通気口プラグの圧力に応じて、通気口カバーを撓ませて通気口プラグを通気口から除去することによって通気口から通気口プラグから外すのに十分な力を熱暴走ガスが通気口プラグに対して及ぼすまで通気口プラグを通気口の中に保持するように適合される。
