Chapter 2
Section A & B
An intro into heavier than air flight.
Clark Philbert, Colten Westhues, Riley
Vogelsmeier, Savanna Schietzelt
Leonardo da Vinci
●
Flapping-wing ornithopters
â—‹
â—‹
●
Da Vinci’s attempt to define
heavier-than-air flight
The attempt was unsuccessful
Redesigned into fixed-wing gliders
â—‹
â—‹
Was more relative
Remained relatively unknown
and unpublicized so wasn’t a
big influence in the aircraft
scene
Kites and Windmills
●
Kites
â—‹
â—‹
â—‹
●
A Chinese invention
Dates back to the 1st century or earlier
“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.”
Windmills
â—‹
â—‹
Originates in ancient Rome
Recognized importance as a propeller in
1784
â–  Lead to many different inventions
including:
● A simplistic helicopter with
rotors on both ends of a pole
(1784)
● A propeller for a river boat,
and later on balloons (1785)
Sir George Cayley
●
●
Conceived the idea of the modern
airplane
In the 18th century he identified the
problem of mechanical flight
â—‹
●
●
“To make a surface support a given
weight by the application of power to
the resistance of the air.”
Distinguished between the mechanism
for lift and the mechanism for thrust
In 1809 Cayley built a full-sized glider,
which flew unmanned successfully
â—‹ Advances continued to be made
after this success
William Samuel Henson and John Stringfellow
●
Englishmen who collaborated together after
being inspired by the Cayley’s successes
(1835-1847)
●
Henson had already experimented with gliders,
and Stringfellow had launched a couple
balloons
●
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 couldn’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
connecting ribs.
●
Henson’s design also included a vertical
stabilizer and the steam engine powered two six
bladed pusher propellers
●
Failed fly, 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
Henson’s, which was only a 10 foot model of the
monoplane
●
It was a “launch by wire” design, meaning it
hung from an inclined wire and slid down
creating speed
●
According to his biographer, stringfellow
established the first unmanned, powered,
winged flight… although this is sometimes
disputed
●
His success inspired many aeronautical efforts
later on and revived aviation interest
Felix du Temple
●
Was a French Naval Officer 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 first powered
flight of a heavier than air aircraft, while others
claim it was the just the first powered take off
and landing
Otto Lilienthal
●
Thought that flight 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 flights in.
●
He died after crashing into a hill, his last words
were “Sacrifices must be made.”
Octave Chanute
●
Improved Lilienthal’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 flew
over the Indiana Dunes on the shore of Lake
Michigan
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 flight
Other Notable Innovations
●
●
Alphonse Penaud of France built and built the
Planophore, a plane driven by a big twisted
rubber
Penaud achieved stability with a dihedral wing
Thanks to all of the previous innovators of
aeronautics, it paved the way for the first powered
flight by the wright brothers
The Wright Brothers- Wilbur & Orville
●
Interest in aviation early in life.
●
Both bought bicycle shops
●
Lilienthal’s death reinspired Wilbur
●
Both became engineers and inventors in aviation
●
The biplane kite was the start
â—‹
●
Horizontal, change in CG, & Lateral stability
Time working at the bicycle shop helped the
brothers
â—‹
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.
Gliders
●
First full-sized glider finished in 1900

Features
â– 
Wing wrapping
â– 
Moveable forward elevator

Moved project to Kitty Hawk, North Carolina
●
Each trial came with a lesson
In late 1902 the Wrights finally solved
the control issue, their next task was
solving the power issue.
“When once a machine is under proper
control under all conditions, the motor
problem will be quickly solved”
-Wilbur Wright
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
cooled designs.
The Wright brothers soon discovered
that a propeller is an airfoil that
rotated.
They opted to use two pusher
propellers, setup in a counter-rotating
configuration.
Each blade was 8.5 feet in diameter
and was connected to the engine
with a modified bicycle chain.
On December 14, 1903 the Wright
brothers bring their new aircraft, Flyer,
to Kitty Hawk for the first airplane
flight.
On December 17, 1903 the Wright
brothers brought the repaired Flyer
back to the test site, and made the first
flight in an aircraft.
Orvilles first flight lasted only 12
seconds, and carried him only 120 feet.
Wilbur made the last flight of the day.
Traveling 852 feet over 59 seconds.
This is counted as the first first
manned, powered, controlled, and
sustained flight.
