	Albuquerque International Balloon Fiesta
		Gas balloons ascend because the gas inside is less dense and lighter than the air on the outside of the balloon.
		Gas balloon pilots typically started out flying hot-air balloons, and then decided they wanted to be able to fly farther, higher and longer.
		Gas balloon pilots may prepare for months before a competition, and when they’re racing, they sometimes fly into dangerous weather conditions or over open seas, where an emergency landing could be a disaster.

	What are balloons made of
		When the balloon is filled with air, the pilot turns on the burner which heats the air inside, causing the balloon to rise.
		A balloon cannot be steered since it is being carried by the wind at the exact speed of the wind.
		The balloon envelope is spread on the ground and the gondola laid on its side and attached to the envelope cables.

	Balloon (aircraft) - Wikipedia, the free encyclopedia
		There is a special type of gas balloon called superpressure balloons that can operate with the lifting gas at pressure that exceeds the pressure of the surrounding air with the objective of limiting or eliminating the loss of gas from day-time heating.
		The third balloon type was invented by Pilâtre de Rozier and is a hybrid of a hot air and a gas balloon.
		One reason for this was the hydrogen that filled the balloons was highly flamable, and planes assigned to attack enemy balloons were often equiped with incendiary bullets, for the purpose of igniting the balloon.

		In 1932 the Swiss physicist Auguste Piccard, one of the major figures in 20th-century ballooning, ascended in a balloon with a sealed spherical gondola to a height of 55,500 ft (17,000 m); since then manned balloons have reached heights of 100,000 ft (30,500 m) and unmanned balloons have exceeded 140,000 ft (42,500 m).
		In contemporary sporting balloons, which use air heated by a small gas-fired burner, altitude is controlled by varying the temperature of the heated air.
		Gas bags made with space-age materials are more durable and weigh far less than the traditional silk; heaters have similarly become more efficient.

	Aircraft having buoyant gas balloon - Patent 4366936
		The spherical balloon is rotatably mounted on a normally horizontal axle having end portions projecting from opposite sides of the balloon, and includes a rigid load supporting yoke including two arms extending upwardly from a central load supporting structure and each with an upper end suspended from the axle.
		The term "superpressure balloon" as used herein means a balloon of non-elastic material, having essentially fixed dimensions and shape which, once the balloon is properly inflated, do not change by reason of the type of changes in external pressure and temperature which occur with normal atmospheric changes and changes in altitude.
		As indicated the balloon is preferably rotated in normal flight in such direction that the surface of the balloon facing its forward direction of movement moves upwards relative to the centre of the balloon, so that the rotation supplies additional lift to the airship due to the Magnus effect.

	Halfbakery: Steam balloon
		A conventional hot air balloon generates lift because the density of a particular gas at a given pressure is inversely proportional to its absolute temperature (in degrees Kelvin).
		A helium balloon generates lift because the density of a gas at a given temerature and pressure is inversely proportional to its molecular weight.
		Although balloons fly with the wind, there are still shears of wind to reckon with and it is always a concern when the envelope catches the wind and begins to spin and tilt.

	Plano Balloon Festival - Plano, Texas
		They decided to capture its lifting powers with small paper and cotton balloons and, while they were mistaken in their faith in the smoke itself (or 'Phlogiston' as it was referred to at the time), they succeeded in creating the world's first hot-air balloon.
		Heat for the balloon was generated by a straw fire carried in a brazier slung beneath its mouth and the two men were carried in a narrow gallery encircling it.
		However as the balloon was only made of paper and cotton they spent much of their time either tending the flames or dabbing out little fires from the smouldering embers with wet sponges fixed on to the end of long sticks.

	Gas balloon - Wikipedia, the free encyclopedia
		A gas balloon is any balloon that stays aloft due to being filled with a gas less dense than air or lighter than air (such as helium or hydrogen).
		Gas balloons were used in the American Civil War, the Napoleonic Wars (to very limited extent), and throughout the 19th century by hobbyists and show performers such as the Blanchards.
		Gas balloons are regularly used for high-altitude research (such as with weather balloons) and for record-breaking manned balloon flights.

		Today, in France, gas balloons are known as Charliers and hot air balloons are known as Montgolfiers.

	Concepts for Autonomous Flight Control for a Balloon on Mars
		At night, the thermal balloon provides no lift, and the balloon system drifts over the Martian surface; the lift of the gas balloon is intended to be just sufficient to prevent the science payload from hitting the ground.
		At sunrise, the thermal balloon is heated by sunlight, complementing the lift of the hydrogen-filled balloon, and causing the entire vehicle to rise to its float altitude, where it cruises all day.
		Another control issue involves the use of ballast to compensate for gas losses in the gas balloon, and for losses in the efficiency of the thermal balloon due to degradation of the envelope film.

	Ballooning FAQ
		Most modern balloons are made out of nylon with a special coating that helps the fabric to retain heat.
		Gas balloons are inflated using helium and occasionally hydrogen.
		A hot air balloon will have a variometer, which displays the rate of ascent or descent, a pyrometer, which details the temperature inside and outside of the balloon, and an altimeter.

	Pressure and the Gas Laws
		In the example of the balloon (above), there is not only gas inside the balloon (exerting pressure from the inside), but there is also gas (air) on the outside, exerting pressure onto the outside surface of the balloon (Figure 2).
		Because the balloon’s skin is elastic, it expands upon this increased pushing from inside, and the volume taken up by the same mass of gas increases with temperature.
		The equation of state or ideal gas law is one of the most fundamental relationships linking the three variables temperature, pressure and density that describe the thermodynamic state of the atmosphere.

	Balloon HQ presents: Why do helium-filled balloons float?
		Well, if the balloon doesn't get any bigger at all, the answer would be no. If the answer was that the balloon stretches a tiny bit bigger, then I'd have to know; did the tiny increase in size add enough lift to offset the extra weight of helium added.
		As the balloon rises, it lifts more of the ribbon from the floor, until the weight of the ribbon equals the lift of the balloon, and a state of equilibrium is reached.
		From my 13 years in the balloon industry, I have found that the change in pressure in a helium tank is almost proportional to the change in volume.
