Report
Hot Air Balloons
Joey Hendrickson
and
Georgette Green
The Inventor
• 1766
• Henry Cavendish isolated hydrogen
– (the lightest gas)
• Proposed it could lift objects
• Never pursued idea
First Uses
• 1782
Joseph Michel Montgolfier
– Filled silk bag with hot air
– Bag floated to the ceiling
• 1783
Montgolfier and brother Jacques Etienne

–Launched 70 ft. tall balloon
–Carrying two people
went 3000 ft. in the air
–Were airborn for 25 minutes
Innovations
of the Hot Air Balloon
• The parachute in hot air balloon was
added in 1785
• Sandbags were added later to bring the
hot air balloon to the ground
(to set up weight distribution differently?)
Classification
of Hot Air Balloon Invention
• Transportation
– Used originally for
traveling short distances
– Now used more for
leisure activity
Effect on Society
• First successful type of transportation by
air for humans
• Early models and
experiments were
very prone to
crashes
Creating the Hot Air Balloon
• The Science…
– Discovery of the difference between the
“weight” of hydrogen and the “weight” of
oxygen (“lighter than air” properties)
• The Technology…
– The desire to create a form of transportation
that uses the “lighter than air” principal that
can carry humans long distances
Creating the Hot Air Balloon
• The Engineering…
– Design and create a mode of transportation
that holds an amount of a gas that is “lighter”
than air and uses that principle to float and
transport people
– What shape should be utilized?
• The Math…
– How large of a balloon is necessary?
– How many humans can be carried?
Purpose of Hot Air Balloon
• Give humans the power of flight
• First success in air travel
Hot Air Balloon Quote
“The best way of travel, however, if you
aren't in any hurry at all, if you don't care
where you are going, if you don't like to use
your legs, if you don't want to be annoyed at
all by any choice of directions, is in a
balloon. In a balloon, you can decide only
when to start, and usually when to stop.
The rest is left entirely to nature.”
— William Pene du Bois, 'The Twenty-one Balloons.'
