aeolipile , also: eolipile

It is not known whether the aeolipile was put to practical use in ancient times.

It uses the same principle as Hero's aeolipile.

This principle can be seen in the aeolipile of Hero of Alexandria.

The aeolipile represents the use of steam by the rocket-reaction principle, although not for direct propulsion.

However, the aeolipile was a reaction engine, inefficient as a stationary engine.

Jet engines can be dated back to the invention of the aeolipile before the first century AD.

Some historians have conflated the two inventions to assert that the aeolipile was capable of useful work.

The aeolipile Hero described is considered to be the first recorded steam engine or reaction steam turbine.

Vitruvius, on the other hand, mentions use of the aeolipile for demonstrating the physical properties of the weather.

The Romans were the first culture to assemble all essential components of the much later steam engine, when Hero built the aeolipile.

The steam engine was invented by Hero of Alexandria, (this is debatable) and was named the aeolipile.

In the following centuries, the few steam-powered "engines" known were, like the aeolipile, essentially experimental devices used by inventors to demonstrate the properties of steam.

They are probably best known for their use in rocket-powered cars and motorcycles, and they are the type used in aeolipile.

Hero published a well recognized description of a steam-powered device called an aeolipile (hence sometimes called a "Hero engine").

The aeolipile described in the first century BC (often known as Hero's engine) essentially consists of a steam rocket on a bearing.

A 1979 Soviet animated short film focuses on Heron's invention of the aeolipile, showing him as a plain craftsman who invented the turbine accidentally.

Various inventions by Hero of Alexandria, including the steam turbine (aeolipile), water organ, and various other water-powered machines.

An aeolipile (or aeolipyle, or eolipile), also known as a Hero engine, is a rocket style jet engine which spins when heated.

In one of Trevithick's more unusual projects, he attempted to build a 'recoil engine' similar to the aeolipile described by Hero of Alexandria in about AD 50.

It bears no relation to any later application of steam power and is not much of an advance over the aeolipile described by Hero of Alexandria in the first century AD.

The history of the steam engine stretches back as far as the 1st century AD; the first recorded rudimentary steam engine being the aeolipile described by Hero of Alexandria.

He also describes the construction of sundials and water clocks, and the use of an aeolipile (the first steam engine) as an experiment to demonstrate the nature of atmospheric air movements (wind).

In recognition of the aeolipile's contribution to steam engineering, the U.S. Navy chose a semblance of the aeolipile for the Boiler Technician rating badge.

The aeolipile consists of a vessel, usually a "simple" solid of revolution, such as a sphere or a cylinder, arranged to rotate on its axis, having oppositely bent or curved nozzles projecting from it (tipjets).

When his writings on hydraulics, pneumatics, and mechanics were translated into Latin in the 16th century, Hero's readers initiated reconstruction of his machines, which included siphons, a fire engine, a water organ, the aeolipile, and a programmable cart.
