Hot air

From Inventing aviation
Jump to navigation Jump to search

Hot air, enclosed by a balloon and created typically by an onboard flame, has lower density than the surrounding air and can therefore cause a vessel to rise.

The Frères Montgolfier are considered to have begun the balloon age in 1783 by flying in such a vessel, which type then became known as a montgolfière.

In 1709 Bartolomeu Lourenço de Gusmão demonstrated a small hot-air balloon at the Portuguese court.

In one instance, heated ballooning air was called air dilaté, i.e. expanded air.
