Ballonet

A ballonet is an air bag inside the main balloon of an LTA aircraft, enabling the operator to increase the pressure inside the main balloon. As the operator lets out hydrogen to descend, he adds compensatory atmospheric air to the ballonet, thereby maintaining the overall gas pressure and shape of the envelope.

Can also refer to a simple balloon compartment, as in Patent GB-1910-14688. ("the airship is supposed to be 1,000 feet long, 65½ feet in diameter, and divided into 51 balloonets" [does the double "o" make a difference?]).

According to one history, the ballonet was invented by General Jean Baptiste Meusnier, one year after the first Montgolfier ascent, and then revived by Dupuy de Lôme in 1872. The author, Alphonse Berget credits captain Charles Renard with demonstrating the necessity of the ballonet.

Berget mentions de la Vaulx's spherical balloon Le Djinn as a good example of the ballonet in use.
