AEROSPACE 1,2,3,4 Flashcards
How flying and walking are similar
-Need power to get going
-Need more power as load get heavier
-Need place to store power
Escaped from prison by “donning the
work clothes of a bird.”
Legend of emperor Shun
Built a flying chariot that had no visible means of support
Ki-kung-shi
100 BC Chinese invented
kite
Attempted a flight to the Moon using a large wicker chair to which were fastened 47 large rockets
Wan Hoo
Great Italian artist, architect and man of science made the first scientific experiments in the field of aviation.
Leonardo da Vinci
He understood and wrote about the
importance of the center of gravity, center of
pressure and streamlining.
Leonardo da Vinci
Flying machines that are kept aloft and propelled by flapping wings
Ornithopters
Atmospheric pressure decreases as you go
Higher
Measures the pressure of the atmosphere
Barometer
Allowed them to study vacuums
Air pump
Wrote about an “aerial ship.” This airship would be carried aloft by four large spheres from which all air had been removed to make them lighter than the surrounding air.
Francesco de Lana
Most important development in the first lighter than air flight
Reduced cost of printing which allowed for distribution of information
Credited with inventing the hot-air balloon. In 1709, he demonstrated a small hot air balloon for the King of Portugal.
Laurenco de Gusmao
Discovered a gas which he called “flammable air.’’ Later named hydrogen, this gas is important
because it is lighter than air.
Henry Cavendish
Realized that if this light gas were enclosed in a thin bladder, it would weigh less than the surrounding air and would therefore rise
Joseph Black
First to fly in hot air balloon
Montgolfiers
Made the first parachute jump from a balloon flying at an altitude of 3,000 feet in 1976.
Andre-Jacques Garnerin
First use of balloons in U.S military
Civil War
Balloons major problem
Could not steer
-Suggested changing the shape of a balloon from a sphere to the shape of
a football
-Suggested an envelope (container for the gas) made of several compartments and a passenger car shaped like a boat attached to the bottom of the dirigible by a system of ropes.
Jean Baptiste Meusnier
Built a cigar-shaped dirigible 114 feet long and 39 feet in diameter. The dirigible was powered by a 3 horsepower steam engine that pushed it at a speed of about 5 mph. This dirigible is generally credited as being the first successful one in the world.
Henri Giffard
It was not until the invention of the … that dirigibles became a real success
Internal combustion engine
Built the first dirigible powered by an internal combustion engine in 1872
Paul Haenlein
