[4K]海上自衛隊そうりゅう型潜水艦 関門通峡 汽笛あり JMSDF Soryu-class Submarine - 2022

あんなに大きく、早いのに、引き波がたたないのは、すごいですね。

[@binmei]

そういえばそうですよね。この場所は波打ち際にとても近くて潮位と引き波の程度によっては三脚や足元に潮がかかってしまうこともあるのですが、潜水艦でそんなことはこれまでなかったですね、サンプル数がごく少ないですけどｗ　水中の形状が理想的な流線形をしているからでしょうか？？　コメントありがとうございます。

👍🏼 So interesting to see! Thank you! 😎✌🏼

Thanks for watching!

Thank you very much for the explanation regarding steam, awesome😀, greetings from Brazil.

[@binmei]

Thanks for watching and commenting! Greetings!

[@SchiffsKanal]

Awesome! Incedible with all that steam coming out right above the water...

[@binmei]

That steam is said to be seawater to cool the battery being charged. Thanks for watching.

[@terryboyer1342]

The amount of steam it produces is amazing! I have to learn more about the propulsion system.

[@binmei]

Hi Terry-san. Thanks for watching. That white smoke is seawater to cool the heat when charging the battery. The Soryu-class submarine stores the energy generated by the diesel engine in the battery while it is surfacing. When diving, it is propelled by the propeller with the power of the battery.

[@terryboyer1342]

@@binmei Thank you Binmei-san! I'm curious as to what method is used to charge the battery? It can't be a diesel engine as they don't produce that much heat. How often do they have to surface to recharge the battery or can that be done while submerged? I'm very fascinated by this as I've never seen another submarine do this.

[@binmei]

The battery is charged by a diesel engine on the surface of the water. Its frequency and charging time are military secrets. I thought this was a common propulsion method for submarines except nuclear submarines. Soryu-class submarines used to use lead-acid batteries, but in recent years they have been replaced by lithium-ion batteries.

[@terryboyer1342]

@@binmei I've never seen a diesel engine produce steam like that. I know lithium ion batteries produce heat when charging but the amount of steam is incredible. Diesels can recharge batteries while submerged using a snorkel. I'm wondering if Soryu can do this also or if it must be totally surfaced to recharge. The system doesn't seem very stealthy as every time it recharges it must surface and generate huge temperatures and steam. I'm just very puzzled by this submarine! But it must make sense and work since they built and are using it. Thanks for responding!

[@binmei]

At this time she surfaced and sailed through a narrow, shallow strait. I think she can also charge with a snorkel. Since Japan has high humidity, water vapor may be more noticeable.

おはようございます。 近くで鮮明なので迫力がありますね。 私の場合、老の山からなので、遠くからですが、今回はビートルのおかげでラッキーでした。 航路アウトにつれて潜航し始めるのも少し見れて良かったです。 いつもありがとうございます。

[@binmei]

老の山公園ですか、位置確認しました。今度行ってみます。ビートルに乗ってた人はラッキーでしたよね。コメントありがとうございます。

[@user-yn9dc6ce6b]

実際に潜水艦がこんなに近くに見られるなんて🎌⚓

[@binmei]

そうなんですよ。艦上の隊員さんとも大声を出せばお話しできそうな感じです(笑)　コメントありがとうございます。

[@出ベソ世界の]

装輪装甲車が国道を走るとき、見張りがハッチを空けて立っています。潜水艦も同じだ。

[@binmei]

なるほど、乗用車もルーフの上から見張る人がいたら事故減らせるかもですね(笑)　コメントありがとうございます。

[@cyliao4778]

是否在海測，沒看到舷號？

[@binmei]

Japan Maritime Self-Defense Force submarines do not display ship numbers. Thanks for watching my video.

[@f4802]

何処を見ても絵になるね、全力エンジン回転と思われるが、海中だとソナーに探知されるるね。 赤間天満宮もはっきり見えますね。
