riggerrob 643 #1 September 3, 2014 Time to think outside the box (boat?) boys and girls Can you dream up a profitable civilian mission for a flying submarine? Delivery is easy ...... SEALS do it every day. The challenge is taking off at the end of the mission .... sure, the USNavy launches cruise missiles from submarines every day .... Ho hum You can launch anything with enough rockets. The challenge in launching a civilian submarine is taking off gradually enough that you do not break the passengers' necks. After a hard day of touring the Great Barrier Reef how do you return a submarine full of wealthy tourists to the beach-side resort for sunset cocktails?

quade 4 #2 September 3, 2014 As fun as the "Flying Sub" was in "Voyage to the Bottom of the Sea" it was also pretty dumb in terms of science. Submarines and aircraft have two fundamental design challenges to overcome which are largely mutually exclusive. The submarine has to withstand a LOT of pressure even if just going down a 33 ft. To do that requires quite a bit of weight. To fly requires things to be relatively light. Propulsion has similar issues. I simply don't see a viable way to make that vehicle for commercial use.

Any peasant can climb from a boat into a float-plane/helicopter but they get DAMP in the process! Ick! Ewwwww! The challenge is keep wealthy, arthritic customers dry on their way back to the resort.

riggerrob 643 #4 September 3, 2014 Can we start by agreeing that aircraft can only lift light-weight pressure hulls? That limits our submarine to shallow dives. What if you kept the "soft" hull pressurized during the flight back to the resort? What if the primary goal was to avoid "bending" wealthy tourists by very slowly decompressing them? Their time is far too valuable to waste during decompression stops, hanging unto a rope ten metres below the boat. They have more important things to do, people to meet, deals to seal, coke to snort, hookers to blow ?????? .... or is it the other way round? Quote Share this post Link to post Share on other sites

riggerrob 643 #8 September 4, 2014 What of Mr. Poutine wanted to assert his control of the Arctic Ocean floor below the North Pole, but had to return to Moscow for a dinner date How deep is the sea bed under the North Pole. How long does it take to fly from the North Pole to Moscow in an IL-76 jet transport? Does that provide enough hours to gentle oh de-compress? Though My first thoughts were of a de-compression chamber small enough to fit in a Twin Otter or Sikorsky Sea King helicopter. Quote Share this post Link to post Share on other sites

Finally, a response from someone who can think outside the box ... Er ...... boat. If you always keep the passenger cabin pressurized slightly more than ambient, it could work with a surprisingly light-weight cabin. I was even contemplating making most of the passenger cabin from flexible materials, like rubberized canvas used to make fuel bladders and Zodiac boats. Granted, a soft hull would not work at 4 kilometres under the North Pole, but it might work at the 10 or 20 meter depths popular with tourist scuba divers.

At 33 ft below the surface, the 100 cubic foot cabin would be about 50 cubic foot. I'm not really sure how your design is going to accommodate for that and is probably a significant factor in why such a design doesn't currently exist anywhere.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites

As long as internal (air) pressure exceeds external (water) pressure, you should be able to get by with quite a flimsy hull. Think about diving bells. Diving bells don't even have floors. Diving bells depend purely on internal air pressure keeping water out. Quote Share this post Link to post Share on other sites
