Timeline of heat engine technology

Jump to: navigation, search

This Timeline of heat engine technology describes how heat engines have been known since antiquity but have been made into increasingly useful devices since the seventeenth century as a better understanding of the processes involved was gained. They continue to be developed today.

In engineering and thermodynamics, a heat engine performs the conversion of heat energy to mechanical work by exploiting the temperature gradient between a hot "source" and a cold "sink". Heat is transferred to the sink from the source, and in this process some of the heat is converted into work.

A heat pump is a heat engine run in reverse. Work is used to create a heat differential. The timeline includes devices classed as both engines and pumps, as well as identifying significant leaps in human understanding.

Pre Eighteenth century[edit]

  • Prehistory - The fire piston used by tribes in southeast Asia and the Pacific islands to kindle fire.
  • c. 450 BC - Archytas of Tarentum used a jet of steam to propel a toy wooden bird suspended on wire.[1]
  • c. 200 BC - Hero of Alexandria's Engine. Demonstrates rotary motion produced by the reaction from jets of steam.
  • c. 900s - China develops the earliest fire lances which were spear-like weapons combining a bamboo tube containing gunpowder and shrapnel like projectiles tied to a spear.
  • c 1100s - China, the earliest depiction of a gun showing a metal body and a tight-fitting projectile which maximises the conversion of the hot gases to forward motion.
  • 1120 - Gerbert, a professor in the schools at Rheims designed and built an organ blown by air escaping from a vessel in which it was compressed by heated water.
  • 1232 - First recorded use of a rocket. In a battle between the Chinese and the Mongols. ( see Timeline of rocket and missile technology for a view of rocket development through time.)
  • c. 1500 - Leonardo da Vinci builds the Architonnerre, a steam-powered cannon.
  • 1551 - Taqi al-Din demonstrates a steam turbine, used to rotate a spit.[2]
  • 1629 - Giovanni Branca demonstrates a steam turbine.
  • 1662 - Robert Boyle publishes Boyle's Law which defines the relationship between volume and pressure in a gas.
  • 1665 - Edward Somerset, the Second Marquess of Worcester builds a working steam fountain.
  • 1680 - Christiaan Huygens publishes a design for a piston engine powered by gunpowder but it is never built.
  • 1690 - Denis Papin - produces design for the first piston steam engine.
  • 1698 - Thomas Savery builds a pistonless steam-powered water pump for pumping water out of mines.

Eighteenth century[edit]

Nineteenth century[edit]

Twentieth century[edit]

Twenty first century[edit]

  • 2011 - Michigan State University builds the first wave disk engine. An internal combustion engine which does away with pistons, crankshafts and valves, and replaces them with a disc-shaped shock wave generator.[5]
