Cluster ballooning was inspired by Larry Walters's experience, although his was not the first. [1]On July 2, 1982, Larry Walters (April 19, 1949 – October 6, 1993) made a 45-minute flight in a homemade aerostat made of an ordinary lawn chair and 42 helium-filled weather balloons. [2]
The Union Army Balloon Corps was a branch of the Union Army during the American Civil War, established by presidential appointee Thaddeus S. C. Lowe.It was organized as a civilian operation, which employed a group of prominent American aeronauts and seven specially built, gas-filled balloons to perform aerial reconnaissance on the Confederate States Army.
The key to understanding the behavior of the balloons is understanding how the pressure inside a balloon varies with the balloon's diameter. The simplest way to do this is to imagine that the balloon is made up of a large number of small rubber patches, and to analyze how the size of a patch is affected by the force acting on it.
Britain used free balloons in a number of ways including Operation Outward which launched nearly 100,000 small balloons to drop incendiaries on German occupied Europe or to trail wires to short out electrical distribution cables. Balloons also were used at sea, particularly by the US Navy for anti-submarine work. [24]
In 1933, Lieutenant General Reikichi Tada started a balloon bomb program at Noborito designated Fu-Go, [a] which proposed a hydrogen-filled balloon 13 feet (4.0 m) in diameter with a time fuse, capable of delivering bombs up to 70 miles (110 km). The project was not completed and stopped by 1935.
Fully inflated, a balloon of this size would contain just over 1,000 cubic feet (28 m 3) of helium. [29] Helium's lift capacity at sea level and 0 °C is 1.113 kg/m 3 (0.07 lbs/ft 3) and decreases at higher altitudes and at higher temperatures. The volume of helium in the balloon has been estimated as being able to lift a total load, including ...
