μηχανή του Ήρωνα -> aeolipile, aeolipyle, eolipile, Hero's engine

Η αιολόσφαιρα, επίσης γνωστή ως μηχανή του Ήρωνα, είναι μια απλή ατμομηχανή η οποία περιστρέφεται όταν η κεντρική παροχή νερού θερμαίνεται. Η ροπή παράγεται από πίδακες ατμού οι οποίοι αποχωρούν από την τουρμπίνα, κάτι σαν ρουκετομηχανή. Τον 1ο αιώνα μ.Χ. ο Ήρων ο Αλεξανδρινός περιέγραψε την συσκευή στην Ρωμαϊκή Αίγυπτο, και πολλές πηγές του αποδίδουν την εφεύρεση.

An aeolipile (or aeolipyle, or eolipile), also known as a Hero's engine, is a simple, bladeless radial steam turbine which spins when the central water container is heated. Torque is produced by steam jets exiting the turbine, much like a tip jet or rocket engine. In the 1st century AD, Hero of Alexandria described the device in Roman Egypt, and many sources give him the credit for its invention.

The aeolipile which Hero described is considered to be the first recorded steam engine or reaction steam turbine. The name – derived from the Greek word Αἴολος and Latin word pila – translates to "the ball of Aeolus", Aeolus being the Greek god of the air and wind.

Predating Hero's writings, a device called an aeolipile was described in the 1st century BC by Vitruvius in his treatise De architectura; however, it is unclear if it is the same device or a predecessor, as he does not mention rotating parts.
