The concept of a torpedo existed many centuries
before it was developed as a working device. A possible early description is
found in the works of Syrian engineer Hassan al-Rammah in 1275, who described, "...an egg which moves
itself and burns. Though, torpedos came into use after the mid-19th
century. Torpedos have evolved since the 19th century into extremely
effective undersea weapons.
A torpedo has a
propulsion system, a guidance system and some sort of explosive device.
Torpedoes can travel several miles on their way to the target, and therefore
they need a propulsion system that can run for 10 to 20 minutes. In this
article we will know how the earlier torpedos as well as the modern torpedos
work.
1.) Torpedo
propels itself powered by tank of compressed air
2.)
On launch a valve opens and the air is
released into the engine which contains two pistons. Their motion drives a
propeller which pushes the torpedos for the water
But the air propelled torpedo consists
of a major flaw the compressed air that leaves the torpedo leaves a trail of
bubbles which eventually come on the surface and makes their path of travel
visible which can be easily traced. So it was in during the World War II when
the German Navy designed a torpedo that didn’t advertise its position with the
wake of bubbles. The torpedo which was designed didn’t run on compressed air
but worked with the help of an electric motor that ran on an enormous battery. But
to accommodate the battery the torpedo were needed to be at least 7 meters long.
Today USS Pennsylvania submarine
contains advanced torpedos that are like high tech robots that can be guided on
to their target. An optic fiber spooning
out of the torpedo connects the torpedo to the submarine to obey the officer’s
command to guide it on to the target. As the torpedo closes in, it’s on board
sensors lock on and hit the target.
Torpedos are powerful enough to sink an entire ship or a submarine.
