The History Of Flight
Transcript of The History Of Flight
Leonardi Da Vinci Kites invented in China became the first real kind of flight known at the time.
They built fun and colorful kites used in parades and other special Chinese events.real kind of flight known at the time. An aelipile used L-shaped tubes to force out steam to create a round-about motion. Leonardo da Vinci started the real age of flight by creating over 100 drawings of flying land and water crafts. He successfully designed a flying device called "The Ornithopter". Unfortunately, this machine was never created. It was just a design to show people how to fly. The modern helicopter is based on Da Vinci's design. Pegasus - The Flying Horse Pegasus has wings of wonder in which they contain feathers just like birds. Known for a fight against a three-headed monster. Icarus and Daedalus -Ancient Greek Legends -Icarus is Daedalus' son
-Daedalus flew successfully from
Crete to Naples
-sadly, Icarus fell to his watery grave after his wax wings melted.
King Kaj Kaoos attached birds to his throne and flew around his kingdom to keep watch on nearby enemies King Kaj Kaoos of Persia Humans Can Fly? No, humans cannot fly, but when the idea of flight first came to mind, we did believe that we could fly with wooden feathered wings. The similar structure as bat wings. Hero put a sphere with two holes above a water kettle which a fire turned the water into steam therefore escapeing rapidly out L-shaped tubes causing thrust and made the sphere rotate. Aeolipile: a round vessel caused to rotate by the force of tangentially escaping steam: an early example of jet propulsion. Thrust: to push forcibly; shove; put or drive with force 1783
Joseph and Jacques Montgolfier- First Hot Air Balloon Joseph Michel and Jacques Etienne Montgolfier are brothers and inventers of the first hot air balloon. They used smoke from a fire to fill a silk
bag with hot air. The silk bag was
attached to a basket and
the hot air caused the balloon to
gently lift into the air.
1783: a sheep, a rooster and a duck
were the first passengers that
climbed to a height of about 6,000
feet and traveled horizontally more
than a mile. After that success, men
were sent up in these balloons...
first manned flight was on
November 21, 1783. George Cayley discovered a way that man could fly. He designed many gliders that used the movements of the body to control. A young boy was the first to fly one of his gliders. Over the next 50 years he improved his gliders. He transformed the shape of the wings so that air would flow over wings more freely. He designed tails to increase stability. He also tried to use a biplane look to add strenght to the glider. He realized power would also be needed. 1799 - 1850

Efforts 1891 Otto Lilienthal Otto Lilienthal is a German engineer who studied aerodynamics and tried to design a glider that would fly. He was officially the first person to design and fly a glider long distances. This man was fascinated by the thought of flying. He studied birds to see how they fly; he then wrote a book on aerodynamics that was published in 1889. The Wright Brothers used his text to try and design one for themselves. After 2500+ flights,
he died in a glider crash. 1891 Samuel P. Langley Sam Langley was an astronomer. He realized that power was needed to fly. He built a model and called it an aerodrome which included a steam-powered engine. 1891, his model flew for 3/4 of a mile before running low on fuel. After that, Langley recieved a $50,000 grant to build a full-sized aerodrome which turned out to be too heavy, and crashed. The First Airplane Orville and Wilbur Wright The Wright Brothers learned how the wind would help with flight and how it could affect the surfaces once up in the air. This would be considered as lift. They designed a wind tunnel to test different wing shapes and create tails just like the gliders. On October 5, 1905, the Flyer III was piloted by Wilbur; he flew for 39 minutes which was 24 miles of circles around Huffman Prairie. Wilbur flew the first practical airplane until it ran out of gas. The "flyer" took flight to the north of Big Kill Devil Hill, North Carolina, at 10:35 am on December 17, 1903. Orville piloted the plane which weighed about 605 pounds.

- Gravity: Using gravity to push down on glider while glider moves upward.
- Fluid Friction: Glider moving with with the breeze.
- Static Friction: Using the air to keep glider steady in flight. Final Results: Lift- Launched glider at an angle to increase lift. This
led to the glider flipping over.
Drag- Drag occured when the glider was flying horizontally
while remaining vertical.
Thrust- Occured when escaping my hand in a fast motion.
Weight- Weight was used against the glider... the payload
created too much weight and caused the glider to flip over
and lind on its top. Expected outcomes:
Thrust: to have the exact amount of force to keep glider aloft.
Lift: Expected the glider to stay aloft for approximately 6 seconds.
Drag: Using the air's drag to steady the glider in flight.
Weight: Use to payload weight to my advantage by balancing it perfectly right. Improvements/Modifications
-Increase wing size/area
-Balance payload in the center
