HISTORICAL BACKGROUND• Chapter I of reference covers

– Mythology– Misguided attempts to imitate birds– Ornithopters– Gliders– Powered Aircraft– Balloons and Dirigibles– Rockets

• Read through it at least twice.

The Flight of Icarus

Leonardo da Vinci’s Ornithopter1490

Modern Ornithopter

Sir George Cayley• 1796 - Experimented with helicopters• 1799-1809 Performed many experiments

– whirling arm rig– model glider

• 1809-1810 - Studied– cambered surfaces– pressure distribution on wings– flight control and stability

• 1809 Boy carrying glider

Cayley’s First Airplane (1804)

Had a Fuselage, Tail, wings!He proposed using an engine for thrustNone available at that time.

Otto Lilienthal’s Glider

Crashed and died on a flight in 1896

Doing in Wright!

The first successful flight on December 17, 1903

Montgolfier’s BalloonFlight on November 1783

The Hindenburg explodes, May 6, 1937 at Lakehurst Naval Air Station.

In New Guinea her radios failed but she continued out across the Pacific Ocean and was never seen again.

History of Rocketry

• Chinese used rockets against Mongols - 13th century

• British used to attack Fort McHenry near Baltimore in 1814

• Germans used V-2 against Great Britain in WW II

• Goddard built and tested rockets in 1939

V-2 Rocket

Goddard’s Early Experiments

Rockets are used to place modern satellites such as these in orbit
