EVOLUTION OF AIRPLANES
Transcript of EVOLUTION OF AIRPLANES
(The Wright Brothers)
Creation of the Jet
Success and The Start of Flying
Creations That Changed Flying
By: Anirudh Gadicherla
The Wright Brothers built a successful glider in 1902. (We don't know the exact date).
The Wright Brothers
The Wright Brothers were two men who founded flight.
They did multiple experiments testing lift and other qualities a plane needed to fly and to stay in the air.
After 3 years of research and trials, the Wright Brothers successfully made the first airplane in 1903.
The Wright Brothers successfully made the first airplane.
They named it the "Wright Flyer".
On December 17, 1903 , the Wright Brothers successfully launched their first airplane after some repairs.
The Flyer was airborne for only 12 seconds, but it was a great achievement for them!
They made changes to the rudder, and fixed the lift and control problems that they faced during the 1901 glider trial.
The 1902 glider was aerodynamic and it was fully controlable.
Louis Bleriot created and flew the first succesfull monoplane, the Bleriot XI.
Monoplane- A plane with one pair of wings.
The Bleriot XI used a 50 horsepower Gnome rotary engine.
On July 25, 1909 the Bleriot XI made a jouney across the English Channel from Calais, France to Dover, UK.
Bleriot XI Route
The journey took 36 minutes and 30 seconds.
In 1917, Hugo Junkers built the first all metal plane, the Junker J4.
The plane was made of duralumin, a lightweight aluminum.
This metal made up the fuselage or the body, the tail, and all the other parts of the plane.
This plane was use in WWI
Creation of the Jet Engine
In 1930, Frank Whittle invented the first jet-engine.
Now planes can cross the Atlantic and other oceans faster!
His engine consisted of 10 combustion chambers that produced massive thrust.
The First Commercial Jet
The first commericial airliner was the 1933 Boeing 242.
It had two engines or dual engines and it was also completely made of metal.
This jet carried 10 passengers comfortably.
Adding Comfort to Jets
The Boeing 307 stratoline was the first fully pressurized plane.
The pressurized system let pilots fly the plane to a higher altitude.
When there was disturbing weather, pilots could fly over it so passengers could have a more comforting flight.
The Jet Age
The Boeing 707 jet was equipped with 4 jet engines.
Boeing 747 Jumbo Jet
On February 9,1969 the Boeing 747 took off for its maiden flight.
The design included a hump at the top to fit more passengers.
First class was on the upper deck where there were lounges and entertainment.
The 747 was the biggest passenger aircraft until 2005.
Concorde: A Supersonic Adventure
On March 2, 1969 Concorde took off into the skies for it's years of supersonic flying.
Concorde was the first passenger plane that broke the sound barrier.
Concorde flew at a speeed of mach 2 making journeys across the Atlantic faster.
Concorde was grounded in 2002 after a deadly crash in Paris.
It's first voyage or flight was on December 20, 1957.
The 707 could go transcontinental across the oceans carrying passengers to exotic destinations.
MODERN DAY FLIGHT
The A380 is the world's biggest passenger aircraft.
It has 2 decks that can hold 525 passengers total.
The A380's wing design is curved with 4 turbofan engines.
After the A380, the 787 is a plane that focuses more on comfort and the environment.
The 787 is manufactured to be lighter and more fuel efficient.
It also produces less emissions.
It's wings are made of carbon fiber composites, which make the wings flexible.
EVOLUTION OF AIRPLANES
Creation of The Autopilot
On June 18,1914 Lawrence Sperry created the "autopilot".
Now pilots could fly without controlling the plane all the time.
The autopilot helps on long-distance or international journeys where pilots have to fly several hours.
