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.
The Montgolfier brothers – Joseph-Michel Montgolfier and Jacques-Étienne Montgolfier – were aviation pioneers, balloonists and paper manufacturers from the commune Annonay in Ardèche, France. They are best known historically as inventors of the Montgolfière-style hot air balloon, globe aérostatique, which launched the first confirmed piloted ascent by man in 1783, carrying Jacques-Étienne. Joseph-Michel also invented the self-acting hydraulic ram (1796) and Jacques-Étienne founded the first paper-making vocational school. Together, the brothers invented a process to manufacture transparent paper.
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 aerostat is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered. The average density of the craft is lower than the density of atmospheric air, because its main component is one or more gasbags, a lightweight skin containing a lifting gas to provide buoyancy, to which other components such as a gondola containing equipment or people are attached. Especially with airships, the gasbags are often protected by an outer envelope.
In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. A balloon may be free, moving with the wind, or tethered to a fixed point. It is distinct from an airship, which is a powered aerostat that can propel itself through the air in a controlled manner.
In all forms of aviation aviation, ground crew are personnel that service aircraft while on the ground, during routine turn-around; as opposed to aircrew, who operate all aspects of an aircraft whilst in flight. The term ground crew is used by both civilian commercial airlines and in military aviation.
This is a list of aviation-related events during the 18th century :
A solar balloon is a balloon that gains buoyancy when the air inside is heated by solar radiation, usually with the help of black or dark balloon material. The heated air inside the solar balloon expands and has lower density than the surrounding air. As such, a solar balloon is similar to a hot air balloon. Usage of solar balloons is predominantly in the toy market, although it has been proposed that they be used in the investigation of planet Mars, and some solar balloons are large enough for human flight. A vent at the top can be opened to release hot air for descent and deflation.
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 when he left to establish Raven Industries in 1956, along with several colleagues from General Mills.
Donald Louis Piccard was a Swiss-born American balloon pioneer, promoter, innovator, designer, builder, and pilot.
Hot air ballooning is the activity 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).
The history of ballooning, both with hot air and gas, spans many centuries. It includes many firsts, including the first human flight, first flight across the English Channel, first flight in North America, and first aircraft related disaster.
Kubicek Balloons is a Czech manufacturer of hot-air balloons and airships, the sole such manufacturer in Central and Eastern Europe and one of the largest in the world. From its factory in Brno the company ships its products worldwide.
Dominic Michaelis was an Anglo-French architect, inventor, and solar energy advocate.
On 13 August 1989, two hot air balloons collided near Alice Springs, Northern Territory, Australia, causing one to crash to the ground, killing thirteen people. It was the world's deadliest ever ballooning disaster until February 2013, when a balloon accident near Luxor, Egypt killed 19 people. As of July 2016, it remains the deadliest ever ballooning accident in Australia, and the third-deadliest worldwide, surpassed only by the Egypt crash and a balloon accident in Texas in 2016 that claimed the lives of 16 people.
On 7 January 2012, a scenic hot air balloon flight from Carterton, New Zealand, collided with a high-voltage power line while attempting to land, causing it to catch fire, disintegrate and crash just north of the town, killing all eleven people on board.
Victor Zagainov was a hot air balloon pilot and astronomer from Kazakhstan. He was the first and only hot air balloon champion of the USSR (1991), Hot Air Balloon champion of the Republic of Kazakhstan (1993), the winner of the International Balloon Grand Prix Todi (Italy) (1993), the champion of the CIS (1996). He organized Grand Prix of Zagainov and was awarded Fédération Aéronautique Internationale (FAI) Diploma for Outstanding Airmanship and the FAI Air Sport Medal in 2003.
Eleanor Vadala is an American chemist, materials engineer and balloonist. She became director of research and development at the Naval Air Development Center in Pennsylvania, where she helped to develop light synthetic materials for use in aircraft. One of her jobs was the testing of fabric in existing balloons to ensure they could be used safely.
The Balloon Federation of America (BFA) is a 501c3 non-profit group for the advancement of lighter-than-air aviation which includes hot air and gas balloons. Founded in 1960, located in Indianola, Iowa. The BFA partners with the National Balloon Museum to induct outstanding individuals into the United States Ballooning Hall of Fame. The Federation presents multiple awards including the Ed Yost Master Pilot Award and the National Crew Person Award. The BFA facilitates balloon events by providing advice and guidance on FAA compliance.
