History of Flight
Imagine a Balloon the size of a house!
It has ½ tonne of Helium.
It will Displace about 4 tonnes of Air.
The difference between these 2 weights is the Lifting Force.
Hot Air inside the Balloon is Less Dense than the Air Outside.
25 April 1783
Demonstrate their balloon in Paris. Rose to 305m
19 September 1793
Put the first animals into the balloon, becoming the first passenger flight.
Hydrogen filled balloon
Air released into atmosphere reducing weight and
allowing the Helium gas to expand, giving more Lift.
Air pumped into the Ballonets adding weight and
compressing the Helium gas so that Lift is reduced.
