I'm Italian and this situation in the sea sud of Italy going on from decades unfortunately....but this time the Americans see with hown eyes what like in real life and helping this unlucky people. Thank guys 🇺🇸
What about a hatch on the sub that opens to release a bladder inflated by chemical gas generators like an airbag. In shallow water it could immediately be deployed to bring the sub to the surface like a reverse parachute. In deeper water, two ideas come to mind. First, a computer with it's own battery power supply monitors the rate of ascension and uses solenoid valves to modify the pressure in the bladder. Second the bladder is tethered to the sub and ascends to the surface like a buoy or reverse anchor. Then a winch would lift the sub at a controlled rate. The bladder could also bring to the surface a compressor, solar panels, and communication antenna. The compressor could send fresh air down to the sub and antenna could do an automated sos or allow communication down to the sub. The main benefit of these self contained systems is that they can be deployed before the sub sinks any further. Why wait for the sub to hit the bottom and all of the issues with the increased depth?
What ever happened to the Lockheed DSRV rescue submersible? I worked on this project oh so many years ago in the mid '60's. I penned the top assembly drawing in India ink on mylar which was a 27' long drawing. The DSRV's operational specifications meet or exceed the specifications of the newer designs and was capable of rescuing up to 26 sailors per trip.
My concern is when the sub is on it side or upside down . Have engineers developed procedures to attach the rescue unit to a sub without access to the hatch?
Many pieces of equipment in a sub are held in place by its own weight, the reactor cannot function upside down so it will scram so the boat will shift to backup power also many systems are made to operate upright if you are upside down the emergency propulsion motor cant deploy as its gravity assisted. If the reactor is offline the goal is to get to the surface by blowing main ballast tanks with high pressure air then since the reactor is offline run diesels to start up the reactor if not damaged that is the goal. Now at best speed the epm can drive the sub to the surface at a speed of half to 1 knot to avoid the submarine sinking if the ballast tanks are not blown with high pressure air by having enough speed to have lift over the fairwater planes. The ballast tanks have free flood ports on the bottom to allow water to enter, if the boat does turn upside down any trapped air will spill out making the boat heaver and sink faster and have stability issues. You do have different types of ballast tanks, hard tanks/trim tanks can withstand ocean pressure while main ballast tanks are weaker and are used near the surface with medium and low pressure air while snorkeling. Hard tanks and trim tanks only have so much ability of providing buoyancy vs main ballast tanks. The greatest danger on a boat is flooding then fire as 688 boats do not have high reserve buoyancy compared to russian double hulled boats. You can pump water out of a submarine while its flooding but pumps only have so much compacity and a boat can gain thousands of pounds of wight per second during flooding. Also if the boat is upside down on the bottom you cant deploy emergency distress beacons or use the underwater phone(an/wqc-2) because the transducer would be pointing into mud. So long story short: upside down on a sub is fatal and consider the crew already dead, it would be the worst possible scenario for any submarine.
It's mostly a feel good thing at this point. The suits only work down to 600 feet and even then you have zero time to get moving before you start to suffer from the bends

Well done on 1 million subs

Congratulations 🎉 to us we're now 1M subscribers I've been monitoring this🥰❤️

Looks really great.
Good to Know
If there is such rescue solution why Indonesia submarine sank and soldiers on board lost their lives, without single soul was rescued?

submarines: where you have to worry about your nuclear reactor being sideways

@@unguidedone thanks for taking the time to explain the scenario. "Sounds dangerous" from the Right Stuff
DSRV can mate with NATO subs past 45!°. We all have the same hatches for that reason..
This is nothing new. DSRV and escape suits have been around since early 50s.
ChatGPT is definitely writing this stuff right?
🙂🙂🙂🙂
Yes. Out of the 1 million, 999,999 are fourteen year olds.
Risky business requires courageous people.

It would be lame to be on a submarine with holes in it.
I'm first 😌
You are the first loser of the day. Someone beat you by a minute. Lol.
First gay. Indeed.
I don't see this working. We don't have submarine problems with sinking. Maybe Russia with their 1960s technology but not anyone else.
