Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [14] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...
Aerophile was founded in 1993 by two 25-year-old French engineers from the École Polytechnique, Mathieu Gobbi and Jerome Giacomoni.In 1994, they installed their first large tethered balloon in Chantilly, France) and in 1998, Aerophile celebrated its first flight to an altitude of 300 metres (980 ft).
Traveling an average of 22 mph (35 km/h), Couch used plastic bags filled with 75 litres (20 US gal) of water as ballast against the 105 large helium balloons tied to his lawn chair. Like Walters, Couch had a BB gun on hand to shoot the balloons in order to initiate descent.
High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
Couch, a 47-year-old gas station owner, first flew 193 miles (311 km) in July 2007 riding a lawnchair elevated by 105 large helium balloons.Using amateur instruments to measure altitude and speed, a GPS device to track his location, and 5 gallons (19 litres) of water for ballast, he controlled his descent by releasing water.
