Most modern submarines have one screw (which is the proper term for a propeller). Some of the really big ones have a pair of them, like the Russian submarine Kursk, for example. But the bulk of the designs incorporate a single screw.
Water enters the submarine by entering through the butthole and leaving from the propellers
The propellers move it forward and the rudders guide and steer it left and right
because if you fart in it it keeps the smell awayAns 2 - propellors give the submarine motion through the water
3 Propellers were on the famous RMS TITANIC!
Only if the airplane is in the water. Torpedos are water weapons and seldom, if ever, get airborne. Their propellers don't work in the air.
A submarine can stop due to a combination of factors, including the application of reverse thrust from its propellers, drag forces from the water, and the use of ballast tanks to adjust buoyancy and control descent. By carefully managing these factors, a submarine can come to a controlled stop in the water.
Generally speaking there are 4 propellers. Two of them are crossed over each other that form the main propellers, and the other two are at the rear.
Titanic's outer propellers weighed 38T each and the central one was 22T.
The Titanic had a total of three propellers
A submarine moves forward by using its propeller, which is powered by an electric motor or diesel engine. To move backward, the submarine can reverse the direction of the propeller's rotation or adjust the angle of its hydroplanes to control its depth and direction.
Depends on the type of submarine...
Precision Propellers was created in 1979.
