The First Man to Fly

1896-1903

Who are Wright Brothers?

Two Americans brothers.

Inventors of the world's first successful airplane.

Wilbur and his brother Orville

Wright Brothers Journey

1899 - 1902 – Wright Brothers made research on how things fly.

1901 - 1902– Wright Brothers tested their wings using wind tunnel.

1900 - 1902 – Wright Brothers developed the first flight control systems.

1903 - Wright Brothers developed propulsion system (generate thrust by engine and propeller)

17th December 1903, finally successful

4

(1899 - 1902) – Wright Brothers made Research on how things fly.

Wright Brothers made a research to find out the state of aeronautical knowledge at their time

They read about the works of Cayley, and Langley, and the hang-gliding flights of Otto Lilienthal

Studied the problems which had been encountered by previous flyers and they talked about possible solutions to the problems

1900: Test the Lift force

6

(1901 - 1902) – Wright Brothers Tested Their Wings using Wind Tunnel

1901 - Built a wind tunnel and they tested over two hundred different of wing and airfoil models to improve the performance of their gliders.

Today, aircraft engineers use sophisticated models and wind tunnels to study a variety of problems associated with modern aircraft design

1901: Built a Wind TunnelTest 200 shape of airfoil

Wind Tunnel: research tool to study the effects of air moving past solid objects.

NASA wind tunnel with the model of a plane.

1901: Built the Hangar to store the aircraft

1901: Make 50 Glides, but unsatisfied Performance

1901: Wing design proved to be faulty

13

(1900 - 1902) – Wright Brothers developed the first flight control systems Ideas for control were tested on a series of

unpowered between 1900 and 1902 – kites to obtain aerodynamic performance

Flying object had to be controlled about all three primary axes; roll, pitch, and yaw

Their aircraft were built with movable surfaces on the wing, elevator, and rudder

1902: Solve the control problem………

Roll Around Longitudinal Axis

Pitch Around the Lateral Axis

Yaw Around the vertical Axis

19

(1903 - 1920's) - Wright Brothers Developed Propulsion Systems

First to fly a self-propelled, heavier than air machine

The thin, high speed propellers which they designed were based on wind tunnel tests and were unlike any other propellers being used at that time

Between 1903 and 1913 the engine power increased from 12 horsepower to nearly 75 horsepower

Move from 1902 Glider to the 1903 powered aircraft. Add a engine.

21

December 17, 1903, near Kitty Hawk, North Carolina, Wilbur and Orville Wright made the world's first successful powered, free, controlled, sustained flights in a heavier-than-air craft. Their first flight went 120 feet (37 meters) and lasted only about 12 seconds.

December 17, 1903) - The First Flight

Breakthrough

17th December 1903, finally successful

SummaryWright Bro. Solved 3 Problems 1. How to obtain

LIFT FORCE using the wing.

2. How to make 3-axis aircraft control possible.

3. How to produced THRUST force using engine.

(1904 - 1907) - Flight Development

Continued to perfect their machine with a series of aircraft built between 1903 and 1905. Flight testing from kitty hawk to their home town of Dayton, Ohio

New, more powerful aircraft, they were able to stay aloft for up to a half hour, to fly figure eights, and to even take passengers up for a ride

Heavier-Than-Air Definition

After 1903…….

The brother write to the war department to try and obtain a contract for a “practical flying machine” but are turned down.

They decide to halt flying operations until they get a contract and the patent rights.

They won’t be seen in the air again until 1907 but they continue to work on increasing the power of their engines.

1908…formed the Wright Company Finally in 1908 the War Department

signed a contract for a Wright Flyer, provided it could meet certain tests.

A month later a plan was instituted for the formation of a Wright company in France.

After the successful development of the first airplane, the Wright Brothers continued to be involved in aerospace technology.

Orville was one of the original members of the National Advisory Council on Aeronautics (NACA) which is the parent organization of the current NASA.

Wright Brothers Contribution

Transportation change dramatically. By mid-century air travel was common By late 1950s it had replaced the train

and stream ship as the preferred mode of transport.

By the last quarter of the 20th century, with large, efficient jet-powered aircraft, air travel was commonplace and affordable to all.

Flying has become second nature to hundreds of millions of people and it is impossible to imagine a world without it.

Wright Brothers Contribution

Airplane also rapidly developed as weapon of war. The advent of jet power, and sophisticated

electronics perfected during and after Cold War, has now turned the aircraft into a feared weapon.

Today, aviation and spaceflight are critical tools for the improvement of human conditions and powerful instruments of positive change. The political, social and economic challenges

are different.
