Ballonet

A ballonet is an air bag inside the main balloon of an LTA aircraft, enabling the operator to adjust the pressure inside the main balloon by changing its size.

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.
