An aeolipile, aeolipyle, or eolipile, from the Greek "Αἰόλου πύλη," lit. ' Aeolus gate ' , also known as a Hero's (or Heron's ) engine , is a simple, bladeless radial steam turbine which spins when the central water container is heated.
Hero's aeolipile. A number of devices and inventions have been ascribed to Hero, including the following: The aeolipile (a version of which is known as "Hero's engine"), which was a rocket-like reaction engine and the first-recorded steam engine (although Vitruvius mentioned the aeolipile in De Architectura, presumably earlier than Hero). [13]
1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
Heron’s aeolipile is considered an early demonstration of the principles of steam power, although its practical applications were limited in ancient times. Image credits: Isabella Thornton #62 ...
The 1698 Savery Steam Pump - the first commercially successful steam powered device, built by Thomas Savery [1] The first recorded rudimentary steam engine was the aeolipile mentioned by Vitruvius between 30 and 15 BC and, described by Heron of Alexandria in 1st-century Roman Egypt. [2]
Jet engines can be dated back to the invention of the aeolipile around 150 BC. This device used steam power directed through two nozzles so as to cause a sphere to spin rapidly on its axis. [ 1 ] So far as is known, it was not used for supplying mechanical power, and the potential practical applications of this invention were not recognized.
A big size reconstruction of Heron's aeolipile in Kotsanas Museum of Ancient Greek Technology, Athens, Greece. As noted, one recorded rudimentary steam-powered engine was the aeolipile described by Hero of Alexandria , a Hellenistic mathematician and engineer in Roman Egypt during the first century AD. [ 8 ]
1855 – Lord Kelvin calculates the thermodynamics work and energy due to elastic deformation.
