I need a reflection paper on the topic (wright brothers) explain why you selected it, briefly summarize it, describe how significant it is to the aviation industry, and how it inspires you and leads you to choose the aviation career.

An intro into heavier than air Ã¯Â¬â€šight.
Clark Philbert, Colten Westhues, Riley
Vogelsmeier, Savanna Schietzelt
Leonardo da Vinci
Da VinciÃ¢â‚¬â„¢s attempt to deÃ¯Â¬Âne
The attempt was unsuccessful
Redesigned into Ã¯Â¬Âxed-wing gliders
Was more relative
Remained relatively unknown
and unpublicized so wasnÃ¢â‚¬â„¢t a
big inÃ¯Â¬â€šuence in the aircraft
Kites and Windmills
A Chinese invention
Dates back to the 1st century or earlier
Ã¢â‚¬Å“The kite is in reality a primitive aeroplane a craft supported in the air by the action of
wind upon an inclined surface – and the
windmill is a propeller.Ã¢â‚¬Â
Originates in ancient Rome
Recognized importance as a propeller in
Ã¢â€“Â Lead to many different inventions
Ã¢â€”Â A simplistic helicopter with
rotors on both ends of a pole
Ã¢â€”Â A propeller for a river boat,
and later on balloons (1785)
Sir George Cayley
Conceived the idea of the modern
In the 18th century he identiÃ¯Â¬Âed the
problem of mechanical Ã¯Â¬â€šight
Ã¢â‚¬Å“To make a surface support a given
weight by the application of power to
the resistance of the air.Ã¢â‚¬Â
Distinguished between the mechanism
for lift and the mechanism for thrust
In 1809 Cayley built a full-sized glider,
which Ã¯Â¬â€šew unmanned successfully
Ã¢â€”â€¹ Advances continued to be made
after this success
William Samuel Henson and John Stringfellow
Englishmen who collaborated together after
being inspired by the CayleyÃ¢â‚¬â„¢s successes
Henson had already experimented with gliders,
and Stringfellow had launched a couple
In 1842, Henson developed what he called the
Aerial Steam Carriage
Made a company called Aerial transit company
to raise funds, but could not raise enough to
build the full sized plane.
Aerial Steam Carriage
Although they couldnÃ¢â‚¬â„¢t build the full size, they
built and tested a twenty foot model
It was a monoplane, and the wing was
cambered, braced with king posts, and
constructed with supporting spars and
HensonÃ¢â‚¬â„¢s design also included a vertical
stabilizer and the steam engine powered two six
bladed pusher propellers
Failed Ã¯Â¬â€šy, only a descending glide. Henson gave
up the project and left england.
Although his partner left, Stringfellow persisted.
In 1848, He built an an improved version of
HensonÃ¢â‚¬â„¢s, which was only a 10 foot model of the
It was a Ã¢â‚¬Å“launch by wireÃ¢â‚¬Â design, meaning it
hung from an inclined wire and slid down
According to his biographer, stringfellow
established the Ã¯Â¬Ârst unmanned, powered,
winged Ã¯Â¬â€šightÃ¢â‚¬Â¦ although this is sometimes
His success inspired many aeronautical efforts
later on and revived aviation interest
Felix du Temple
Was a French Naval OÃ¯Â¬Æ’cer who developed his
own ideas and built a full-size airplane
Used a steam engine and a tractor propeller
In 1874, his plane rolled down a lift and hopped
in the air before landing
Some people claim this was the Ã¯Â¬Ârst powered
Ã¯Â¬â€šight of a heavier than air aircraft, while others
claim it was the just the Ã¯Â¬Ârst powered take off
Thought that Ã¯Â¬â€šight would come from
ornithopters, and studied lots of birds
Although he is much more well known for his
gliders, which he logged over 2,000 Ã¯Â¬â€šights in.
He died after crashing into a hill, his last words
were Ã¢â‚¬Å“SacriÃ¯Â¬Âces must be made.Ã¢â‚¬Â
Improved LilienthalÃ¢â‚¬â„¢s design by getting rid of bat
wings and adding a Cayley-type tail, all of this
with stability in mind
An innovation he introduced was the pratt truss
to brace the wing
Because of his age, he hired a young man
named Augustus Herring as the test pilot
Chanute, Herring, and the Wright brothers
Chanutes design succeeded as Herring Ã¯Â¬â€šew
over the Indiana Dunes on the shore of Lake
The Wright Brothers read Chanutes and
contacted him. Chanute met with the brothers
and gave them information, which encouraged
them on their journey for powered Ã¯Â¬â€šight
Other Notable Innovations
Alphonse Penaud of France built and built the
Planophore, a plane driven by a big twisted
Penaud achieved stability with a dihedral wing
Thanks to all of the previous innovators of
aeronautics, it paved the way for the Ã¯Â¬Ârst powered
Ã¯Â¬â€šight by the wright brothers
The Wright Brothers- Wilbur & Orville
Interest in aviation early in life.
Both bought bicycle shops
LilienthalÃ¢â‚¬â„¢s death reinspired Wilbur
Both became engineers and inventors in aviation
The biplane kite was the start
Horizontal, change in CG, & Lateral stability
Time working at the bicycle shop helped the
Funds, woodworking, cycle technology, and
importance of balance and control
The Problem of Mechanical Flight
Plane and Pilot, Stability and Maneuverability.
The Problem with stability.
First full-sized glider Ã¯Â¬Ânished in 1900
Moveable forward elevator
Moved project to Kitty Hawk, North Carolina
Each trial came with a lesson
In late 1902 the Wrights Ã¯Â¬Ânally solved
the control issue, their next task was
solving the power issue.
Ã¢â‚¬Å“When once a machine is under proper
control under all conditions, the motor
problem will be quickly solvedÃ¢â‚¬Â
In 1902 the Wright brothers worked
with machinist Charles Taylor designed
and built a 12hp engine.
The engine was a water cooled
four-stroke engine that weighed 200lb
and had 4-cylinders.
They chose the reliability of water
cooling, over the weight saving air
The Wright brothers soon discovered
that a propeller is an airfoil that
They opted to use two pusher
propellers, setup in a counter-rotating
Each blade was 8.5 feet in diameter
and was connected to the engine
with a modiÃ¯Â¬Âed bicycle chain.
On December 14, 1903 the Wright
brothers bring their new aircraft, Flyer,
to Kitty Hawk for the Ã¯Â¬Ârst airplane
On December 17, 1903 the Wright
brothers brought the repaired Flyer
back to the test site, and made the Ã¯Â¬Ârst
Ã¯Â¬â€šight in an aircraft.
Orvilles Ã¯Â¬Ârst Ã¯Â¬â€šight lasted only 12
seconds, and carried him only 120 feet.
Wilbur made the last Ã¯Â¬â€šight of the day.
Traveling 852 feet over 59 seconds.
This is counted as the Ã¯Â¬Ârst Ã¯Â¬Ârst
manned, powered, controlled, and
