Aerotonon

Aerotonon Aerotonon (aero - air, "tonos" - a tone, a specific sound, also called areotonon, from Ares - god of war.) - a war machine, neurobalist, throwing projectiles on a flat track, invented in ancient Greece, a variant ballistic energy using compressed air.

The idea of ​​building this machine was about 290 r. p.n.e. The Greek inventor Ktesibios was described 30 years after his death in the work of Mechanike syntaxis by Filon of Byzantium. The rods were rotatably mounted and, when applied to the hollow pistons, moving in the metal cylinders, they pressed the air in, while compressing them in the cylinders. The release of the chord caused a rapid movement of the rods caused by the expansion of the air and the pushing of the pistons outward. The way in which the cylinders have been tightened is unknown. The model reconstructed in the Hamburg museum only worked when the compressor was connected. A similar device describes Filon, where compressed air and pistons are replaced by forged bronze springs.

Archimedes used the compressed air to try to construct a steam gun. Bibliography
