Science of war-torpedo. Not all torpedoes are designed to home in on the target and explode on impact. Some are designed to explode several metres below the hull of a ship in order to cause maximum damage. After 0.5 seconds the gas bubble shrinks, under pressure, causing the ship to sag and fracture even more.
Are torpedoes explosive?
In modern language, a torpedo is an underwater self-propelled explosive, but historically, the term also applied to primitive naval mines.
Can torpedoes explode on land?
It would have to hit in an area not protected by pretty thick armor plate to do much damage. If it fell on a heavily-armored area, it would bounce off. It would probably break into pieces in either case. The one thing it would not do is explode.
How destructive are torpedoes?
With advancements in technology, a modern torpedo can destroy a target at a range of 40 km and a speed of about 50 kts. Its destructive power is more than a missile and it can easily differentiate between a target and a decoy.
Do torpedoes sink?
This jet was formed as the gas bubble created by the initial explosion collapsed upon reaching the ships hull. This is the way modern torpedoes sink ships. Everything about the Cheonans sinking is consistent with either a torpedo or submerged mine blowing up beneath the ships keel.
What fuel do torpedoes use?
Otto Fuel II Otto Fuel II is a distinct-smelling, reddish-orange, oily liquid that the U.S. Navy uses as a fuel for torpedoes and other weapon systems. It is a mixture of three synthetic substances: propylene glycol dinitrate (the major component), 2 nitrodiphenylamine, and dibutyl sebacate.
How do torpedoes know when to explode?
On detonation, triggered by recognition of the ships magnetic signature, a spherical gas bubble forms. A high pressure shock wave moves through the water and applies a huge force to the hull crushing it and lifting it out of the water.
Why were ww2 torpedoes so bad?
The mechanical ones were faulty thanks to heavy firing pins that couldnt achieve the right momentum when the torpedo was at full speed, so they were replaced with a lighter metal alloy. Ironically, the alloy chosen had made it into U.S. arsenals after it was discovered in a Japanese fighter shot down at Pearl Harbor.
How many torpedo bombers survived Midway?
One TBF and two B-26s crash-landed on Midway afterward, and only six of the TBDs made it back to the carriers; only three of the aircraft were flyable. Of the 99 men in the 42 torpedo planes that were lost, only three survived the battle.
Why are torpedoes so powerful?
Because contact torpedoes cause the bubble to form against the ships hull, the returning water collects right at the rupture formed by the initial explosion. With so much water rushing into this point, it forces a very strong jet of water to enter the rupture.
Why did US torpedoes not work in ww2?
The Mark 14 torpedo had four major flaws. It tended to run about 10 feet (3 m) deeper than set. The magnetic exploder often caused premature firing. The contact exploder often failed to fire the warhead.
How fast did ww2 submarines go?
Model of the USS Balao (SS-285) Fleet Submarine On the surface, powered by four diesel engines, the Balao had a top speed just over 20 knots (37 km/hr); cruising at 10 knots (18 km/hr) her range was 11,000 nautical miles (20,000 km).
How fast is a torpedo?
The torpedo -- signature weapon of the submarine -- isnt very fast, either. The U.S. MK 48 torpedo achieves a top speed of about 55 knots, or 63 miles per hour.
