Etymology[ edit ] The word torpedo comes from the name of a genus of electric rays in the order Torpediniformeswhich in turn comes from the Latin "torpere" to be stiff or numb. In naval usage, the American Robert Fulton introduced the name to refer to a towed gunpowder charge used by his French submarine Nautilus first tested in to demonstrate that it could sink warships.

Middle Ages[ edit ] The concept of a torpedo existed many centuries before it was later successfully developed. InHasan al-Rammah described " These were used on an ad hoc basis during the early modern period up to the late 19th century.

Early spar torpedoes were created by the Dutchman Cornelius Drebbel in the employ of King James I of England ; he attached explosives to the end of a beam affixed to one of his own submarines and they were used to little effect during the English expeditions to La Rochelle in In the early s, the American inventor Robert Fultonwhile in France, "conceived the idea of destroying ships by introducing floating mines under their bottoms in submarine boats.

However, both the French and the Dutch governments were uninterested in the submarine. Fulton then concentrated on developing the torpedo independent of a submarine deployment. However, the British government refused to purchase the invention, stating they did not wish to "introduce into naval warfare a system that would give great advantage to weaker maritime nations.

Further development languished as Fulton focused on his "steam-boat matters". During the War oftorpedoes were employed in attempts to destroy British vessels and protect American harbors.

This prompted the British Capt. Hardy to warn the Americans to cease efforts with the use of any "torpedo boat" in this "cruel and unheard-of warfare", or he would "order every house near the shore to be destroyed. They used an early form of chemical detonator.

During the American Civil Warthe term torpedo was used for what is today called a contact minefloating on or below the water surface using an air-filled demijohn or similar flotation device. These devices were very primitive and apt to prematurely explode.

They would be detonated on contact with the ship or after a set time, although electrical detonators were also occasionally used. Spar torpedoes were also used; an explosive device was mounted at the end of a spar up to 30 feet 9.

These were used by the Confederate submarine H. French and German inventions followed closely, and the term torpedo came to describe self-propelled projectiles that traveled under or on water. Bythe term no longer included mines and booby-traps as the navies of the world added submarinestorpedo boats and torpedo boat destroyers to their fleets.

InLuppis presented Whitehead with the plans of the salvacoste coastsavera floating weapon driven by ropes from the land that had been dismissed by the naval authorities due to the impractical steering and propulsion mechanisms.Installation.

The Laplace pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between a gas region and a liquid region.

The pressure difference is caused by the surface tension of the interface between liquid and gas.. The Laplace pressure is determined from the Young–Laplace equation given as . Installation. Cut the bubble wrap to the size of the window pane with scissors.
