The Dumaresq Rate-Solver
Вставка
- Опубліковано 13 сер 2011
- In World War I, the problems of fire control in ships had matured at an alarming pace, and the men aiming the guns needed to be able to rapidly compute the "range rate", the rate at which the range to the target was changing over time, so that other devices on board could be set to keep the guns continually on target.
Another component of the fire control problem was that the motion of one's own ship and that of his target ship also created a need to apply "Kentucky windage" to lead the target laterally. The same device that helped in their first instance could help here, too.
For the Royal Navy, this device was called the "Dumaresq" (pronounced "doomarick"). It computed the relative speed of the enemy to that of the user's ship and helped make this data useful.
The video depicts a simulation I created in 2004-2005. There is much more available at dreadnoughtproject.org - Наука та технологія
Thank you, sir.!
Hats off to Mr. Dumaresq.!
That was brilliant, thanks for taking the time to explain it so clearly with good animations.
Good stuff. I like that it sounds like you're inside an armored room in the ship too.
This is still an optical system. This wasn’t fully solved until the Ford mk1 analog computer was linked with radar in early 1943
Pretty awesome! I love this old technology, how the great minds of the past solved the problems that we use computers for today. I used to be a tank gunner; all we had to do -- once we'd done our boresighting correctly -- was to keep the center dot of the reticle on target as we moved and they moved, lase to the target to get the range, and the computer did the rest: the round was goin to go sailing right through whatever that dot was on. The Dumaresq did part of what our ballistic computer did -- but all manually, by eye and through precision engineering and machining.
Incorrect pronunciation. "Demerick" is closers
Source: My some amount of great uncle John Suarez Dumaresq invented the thing and I have the same last name
Very interesting even tho I didn’t understand a word! My only similar experience was manually computing CPA.👍👍
We'd done, thank you.
This was my great grandads invention
We are nerds, you know that right? But seriously, the mechanical and analog computers and sights invented for naval purposes is pretty awesome.
Very informative, never knew about this. But sound quality is pretty poor.
sorry!
What kind potato is your microphone?
Its a phasing Potatoe.
I think he also has a bucket on his head.
🤣🤣🤣
A bad one, I think. Plus, this might have been transcoded once or twice. I did it so long ago.
