The First Hot Air Balloon
First hot air balloon was called the Montgolfiere balloon.
Joseph and Jacques Montgolfiere tried to float bags made of paper and fabric.
When a flame was held below it, the bag expanded and started to float.
First Passenger Hot Air Balloon
Pilatre de Rozier and Marquis d'Arlandes were the first passenger on the hot air balloon.
Montgolfier believed that they
have discovered a new gas, but the
reason the air was lighter in the hot
air balloon is because it was heated
and became more buoyant.
First people to die in a hot air balloon
Jacques Charles and Nicholas Roberts combined their skills and created a hot air balloon made with hydrogen and silk with the coating of rubber.
The hot air was created by a fire that was kept burning, when it cooled, the hot air balloon would come down, the sparks made it likely to set the bag on fire.
Pierre Romain and Pilatre de Rozier are the first people to die in a hot air balloon.
The king at the time wanted the criminals to be the first people on the hot air balloon. Because the criminals were going to die anyways, why not let them test the balloon.
First hot air balloon in United States
President George Washington watched the first hot air balloon in the United States.
The hot air balloon was made by Jean Blanchard.
Jean Blanchard invented the first hot air balloon with flapping devices to control the flight.
As temp. increases, the volume of the hot air balloon also increases.
It is warmer inside the balloon so more particles can move around.
Charle's Law Cont.
Both temperature and volume go hand in hand with the floating of the hot air balloon.
The first passengers on the hot air balloon
The first hot air balloon called the "Aerostat Reveillion" carried a sheep, a duck , and a rooster.
These animals were selected to test the effects of the flight.
It flew for 8 minutes
in front of the king.

Compare and Contrast
July 2, 1990
Ferdinand Zeppelin invented the Zeppelin.
It had an aluminum frame, and was covered with cloth.
There were 5 passengers.
Used hydrogen gas.
The basic principle of buoyancy is established by a Greek philosopher named Archimedes.
When the total weight of the airship or balloon is less than the weight of the air it displaces, it will float.
Sky lanterns are used in many festivals around the world.
Joseph and Jacques Montgolfiere put a flame under a paper bag and it floated, which is similar to the idea of the sky lantern.
Both uses heated gas.
Hot air balloons used hydrogen gas.
Were used for military signal, war, travel, and to draw the Nazca ground figure and lines.
Used hydrogen gas which was produced by the combination of sulphuric acid and iron fillings.
Has a solid iron frame
Uses heated helium gas, heated by a heater fueled by liquid propane.
Used for leisure, advertisement, and weddings.

Modern Hot Air Balloons
Paul Ed Yost invented the modern hot air balloon.
It included a basket, a parachute rip system, and a more effective burner.
The gores are made of rip stop, fire-resistant nylon.
It is reinforced with sewn in webbing.
There are 24 gores.
Also called the crown, or the deflation port.
During the flight, it is sealed tight.
Parachute Valve Cord
When the line is pulled, the hot air rushes out, causing the hot air balloon to descend.
Either made of aluminum and fiberglass or wicker.
Attaches to 24 stainless steel cables of the envelope.
In a shape of a square or rectangle, sometimes triangular.
The propane tanks are used to produce heat to fuel the hot air balloon.
Since propane is odorless, mercaptan, a strong-sweet scent, is added so gas leaks can be
The part that looks like a balloon, also known as "the bag".
Connected to the basket.
Made of fire-resistant, ripstop nylon.
The skirt is connected to the bottom section of the envelope.
It channels the warm air into the balloon, so the warm air doesn't escape.
It protects the burner from the wind.
The Ideal Gas Law
As the tempreture increases, the pressure on the outside remains the same.
The air inside the balloon becomes less dense (more buoyant).
Hot air balloons, just as the name suggests, uses heated air to rise.
Major parts of the balloon are...
The heat produced is enough to heat 120 three bedroom homes.
