Why the water inside US Navy’s indoor ocean is not salty, how test results from a scale model can be translated into a full-size ship, why these rails are curved, even through they look pretty straight, and why with all the advancements in computer modeling, the Navy still relies on old school physical models, is #NotWhatYouThink #NWYT

"the issue is, whoever came up with this design. the solution is to replace that person." Im dead. lmfao
-
Every kids dream pool for their RC boats.
-
"It is the combination of all these experiments performed on scale models that gives designers and shipbuilders the confidence that once the full scale ship hits the water for the first time it will hopefully perform as expected" shows a video of an LCS being launched I see what you did there.

"Do NOT share publicly - Indoors ocean - Cook Unity (high quality video)" That's how the title of this video is translated in Portuguese Who the hell did this XD

I work at the Utah Water Research Laboratory and we often make models of dams (such as the Oroville Dam spillway that failed in 2017, before I started working there), canals, gates, and other water structures, and we use the Froude number in our models. We definitely also have number crunching that happens that accounts for a whole host of things that happen, and being able to have the video recording is very helpful. Basically, we make models so that clients can make informed decisions. Our work can help them save a lot, by spending 5 on a new model saving 85 that would have been spent making the full scale cause the alternate design is way better than the original idea

This is one of the most fascinating NWYT ever!
-
Ending with the LCS was a great touch
-
We have indoor pools where it is possible to simulate winter conditions with real ice crust in Finland. So the whole building is basically a huge freezer.

Always brilliant explanation and lead into the next segment. When you think you already know about a subject, these videos constantly give details you didn't. The tag line applies to every release. Keep up the great work!!

Spent time at the David Taylor towing tank in Bethesda, MD and the towing tank on the Isle of Wight in the UK. Not only ship models are tested. Did the ditching model tests for aircraft, such as the V-22 Osprey Tiltrotor. Well done video, especially the explanation of the Froude number.

Title : USA largest indoor ocean Me: so that’s a large swimming pool right?
-
very informative, thank you! subbed
-
this made my day far better. thank you
-
I have been inside this facility and it is incredible
-
Awesome installation, and great video, but eh: 2:04 "instead of sound, they produce waves." Yeah, sound is waves mate! 😝
-
Great job with this! Thanks!

Decades ago, John Hoyt built a fully functional linear vwave towing tank at the Franklin Institute. I used to run the tank, but then the museum threw the whole thing out over one weekend. It was tragic. John Hoyt went and worked at Carderock. Haven't talked to him in 30 years
-
Fascinating. Thanks!
-
Very cool to learn about this amazing test facility. too bad its not practical to make one of these for every town and city :) swim time. But it really is cool to test the physics of wave model, great people who came up with this plan and helped to build and run this over the years, probably saved a lot of lives and a lot of money.
