How many HP is a submarine?
This reactor in the Virginia Class SSN-774 submarines is designed to operate for 33 years without refueling and last the expected 30 year design life of a typical submarine. It produces about 40,000 shaft horsepower, or about 30 MWth of power.
Do jet engines work underwater?
If you’re wondering if the jets would still operate in the water, no, they would not. There’s not too much to the jet engine besides a series of fans in a specially shaped housing.
Are jet engines powerful?
Aerospace-technology.com lists five of the world’s most powerful commercial jet engines based on thrust. Pratt & Whitney’s PW4000 112-inch ultra-high-thrust engine develops a maximum thrust of 90,000lb. GE90-115B is the world’s most powerful commercial jet engine.
Can you fly under water?
Yes you could! IF it had engines built for underwater use, a plane could technically fly underwater. Since air is a fluid, just like water, a plane could produce lift underwater as well, by using Bernoulli’s principle. It would also experience more drag since water is denser than air.
What engines were used in World War II submarines?
The three engines that seemed to fulfill submarine requirements were the Winton V-type, now known as the General Motors engine; the Fairbanks-Morse opposed piston type; and the Hooven-Owen-Rentschler double-acting type engine.
What are the disadvantages of a pump-jet submarine?
There are drawbacks, as well. They are heavy, making them ill-suited for many smaller submarine designs, and they are costlier and more complex than a propeller. Russia modified a single Kilo class diesel-electric submarine, B-871 Alrosa, with a fairly advanced pump-jet design.
What was the first submarine with a pump-jet propulsor?
The two-thirds of the Royal Navy’s Trafalgar class and later the U.S. Navy’s Seawolf class were among the first standard production submarine designs to rely on the pump-jet propulsor configuration. Today, many other classes have followed suit.
What is the difference between a jet engine and a propeller?
Jet engines can move air through at many times the volume than propeller engines. jet engine horsepower are several times more as well that enable them to turn so many “fan” blades to move far more air through. jet engine air thrust are usually 50K pounds while propeller blades just 5–10K pounds or so.
