Rozière balloon
A Rozière balloon (or simply Rozière) is a type of hybrid balloon that has separate chambers for a non-heated lifting gas (such as hydrogen or helium) as well as for a heated lifting gas (as used in a hot air balloon or Montgolfière). The design was created by Jean-François Pilâtre de Rozier (1754–1785).
A Rozière-type balloon has the advantage of partial control of buoyancy with much less use of fuel than a typical hot air balloon. This reduction of fuel consumption has allowed Rozière balloons and their crew to achieve very long flight times, as much as several days or even weeks.
The first Rozière was built for an attempt at crossing the English Channel on 15 June 1785. Contemporary accounts state that the balloon caught fire, suddenly deflated and crashed near Wimereux in the Pas-de-Calais, killing Rozier, who was riding the balloon.
Today's Rozière designs use non-flammable helium rather than hydrogen. Their primary application is for extremely long duration flights.
The first successful Atlantic crossing was made 31 August to 2 September 1986, Newfoundland to the Netherlands, by Brink, Brink, and Hageman in the balloon Dutch Viking.
During February 1992, the first east-to-west Atlantic crossing was achieved by Feliu and Green.
Four Cameron-R77s made Atlantic crossings, west to east, during September 1992. One was co-piloted by Bertrand Piccard.
Australian adventurer Dick Smith and his co-pilot John Wallington made the first balloon voyage across Australia, in another Cameron-R77 Rozière, Australian Geographic Flyer, on 18 June 1993, earning the 1995 Montgolfier Diploma.
