A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
A blimp, or non-rigid airship, is an airship (dirigible) without an internal structural framework or a keel. Unlike semi-rigid and rigid airships, blimps rely on the pressure of the lifting gas inside the envelope and the strength of the envelope itself to maintain their shape.
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air.
A hopper balloon is a small, one-person hot air balloon. Unlike a conventional hot air balloon where people ride inside a basket, there is no basket on a hopper balloon. Instead, the hopper pilot usually sits on a seat or wears a harness similar to a parachute harness. Hoppers are typically flown for recreation. These aircraft are sometimes called "cloud hoppers" or "cloudhoppers". However, these terms formally refer to the products of a particular manufacturer, specifically Lindstrand Balloons. Nonetheless, "cloudhopper" is used by many people as a genericized trademark, which refers to all craft of this general type. Most hopper balloons have envelopes that range in volume from 14,000 to 35,000 cubic feet and have a maximum flight duration of 1 to 1.5 hours. The two principal commercial balloon manufacturers today offering hopper balloons for sale are Cameron Balloons and Lindstrand Balloons. Most other hopper balloons are experimental aircraft designed and built by amateur constructors.
Paul Edward Yost was the American inventor of the modern hot air balloon and is referred to as the "Father of the Modern Day Hot-Air Balloon." He worked for a high-altitude research division of General Mills in the early 1950s until he left to establish Raven Industries in 1956, along with several colleagues from General Mills.
A thermal airship is an airship that generates buoyancy by heating air in a large chamber or envelope. The lower density of interior hot air compared to cool ambient air causes an upward force on the envelope. This is very similar to a hot air balloon, with the notable exception that an airship has a powered means of propulsion, whilst a hot air balloon relies on winds for navigation. An airship that uses steam would also qualify as a thermal airship.
The Santos-Dumont No. 6 was an airship designed and built by the Brazilian pioneer aviator Alberto Santos-Dumont. In 1901 it was used by him to win the Deutsch de la Meurthe prize for a flight from Parc Saint Cloud to the Eiffel Tower and back within thirty minutes.
Hot air ballooning is the recreational and competitive adventure sport of flying hot air balloons. Attractive aspects of ballooning include the exceptional quiet, the lack of a feeling of movement, and the bird's-eye view. Since the balloon moves with the direction of the winds, the passengers feel absolutely no wind, except for brief periods during the flight when the balloon climbs or descends into air currents of different direction or speed. Hot air ballooning has been recognized by Fédération Aéronautique Internationale (FAI) as the safest air sport in aviation, and fatalities in hot air balloon accidents are rare, according to statistics from the National Transportation Safety Board (NTSB).
Breitling Orbiter was the name of three different Rozière balloons made by the Bristol based balloon manufacturer Cameron Balloons to circumnavigate the globe, named after the Swiss watchmakers Breitling. The third was successful in March 1999 of making the first nonstop flight around the world by balloon. It was piloted by Bertrand Piccard and Brian Jones.
The Airship Industries Skyship 600 is a modern airship, originally designed by British company Airship Industries, further developed by a subsidiary of Westinghouse Electric Corporation. The type certificate holder is now Skyship Services of Orlando, Florida.
The Coastal Class were a class of non-rigid airship or "blimp" used by the Royal Naval Air Service (RNAS) during World War I. The C-class blimp operated by the United States Navy after the war was a completely unrelated design. In total 35 Coastals were built, all at RNAS Kingsnorth, Kent. Entering service in 1916, the Coastal class remained in widespread service until 1918, with a few members of the class still in service at the signing of the Armistice, while others were replaced by the improved C-Star class as they became unfit for service. The blimps were used for long anti-submarine patrols in the Western Approaches and English Channel, protecting convoys from German U-boats. The Coastal class was one of the first aircraft types specifically designed to detect and attack submarines.
The Lebaudy Patrie was a semi-rigid airship built for the French army in Moisson, France, by sugar producers Lebaudy Frères. Designed by Henri Julliot, Lebaudy's chief engineer, the Patrie was completed in November 1906 and handed over to the French army the following month. The Patrie bears the distinction of being the first airship built specifically for military service.
The Willows airships were a series of pioneering non-rigid airships designed and built in Wales by Ernest Thompson Willows in the first decade of the 20th century. The first airship Willows No. 1 flew in 1905, and the last, the Willows No. 5 in 1913.
The Lebaudy République was a semi-rigid airship built for the French army in Moisson, France, by sugar manufacturers Lebaudy Frères. She was a sister ship of the Patrie, the main differences between the two being in the dimensions of the gasbag and the ballonet. Although she was operationally successful, the République crashed in 1909 due to a mechanical failure, killing all four crew members.
The Cameron D-38 is a single seat hot air filled airship, designed and built in the United Kingdom in 1980. The D-50 has a larger volume envelope for thinner or hotter atmospheres. Together, their sales reached double figures.
The Cameron Skystar or DP series is a family of hot-air airships designed and built in the United Kingdom by Cameron Balloons for recreational and advertising use. The first DP series airship flew in 1986. In the 1990 World Hot-air airships the DP series won 1st, 2nd and 3rd places.
The Beta 1 was a non-rigid airship constructed for experimental purposes in the United Kingdom by the Army Balloon Factory in 1910. Reconstructed as Beta II, it was used successfully by the British Army and then by the Royal Naval Air Service as HMA No.17, and was finally struck off charge in 1916.
The Skyship 500 is a non-rigid airship designed and built in the United Kingdom during the 1980s.
On 16 September 1979, eight people from two families escaped from East Germany by crossing the border into West Germany at night in a homemade hot air balloon. The unique feat was the result of over a year and a half of preparations involving three different balloons, various modifications, and a first, unsuccessful attempt. The failed attempt alerted the East German authorities to the plot, but the police were unable to identify the authors before their second, successful flight two months later.
Spirit of Freedom balloon was a Rozière balloon designed and built by Donald Cameron and Tim Cole. In 2002 solo pilot Steve Fossett flew the Spirit of Freedom to become the first successful around-the-world nonstop solo flight in any kind of aircraft. On June 19, 2002, the 10-story-high balloon Spirit of Freedom lifted off from Northam, Western Australia, and landed in Queensland, Australia, on July 3, 2002. The solo flight circumnavigation lasted 13 days, 8 hours, 33 minutes and covered 20,626.48 statute miles (33,195.10 km). They reached speeds of up to 322 kilometers per hour, and flew as high as 10,580 meters.
