Invention of Aeroplane








On December 17, 1903, Orville Wright made the first-ever manned
flight at Kitty Hawk, North Carolina. His flight lasted 12 seconds and
covered a distance of 120 ft(37 m). That same day, Orville’s brother
(Wilbur) made his first flight, which lasted 59 seconds, with the same
aircraft.

Almost five years later, the Wright brothers
were the first to fly
in an airplane for more than one hour. On Sept 9, 1908, Orville Wright
flew for 1 hour, 2 minutes, and 15 seconds. On Sept 21, 1908, Wilbur
Wright flew for 1 hour, 31 minutes, and 25.8 seconds.


Airplane engines may be classified as driven
by propeller, jet,
turbojet, or rocket. Most engines originally were of the
internal-combustion, piston-operated type, which may be air- or
liquid-cooled.


Seventy-five thousand engineering drawings
were used to produce the first Boeing 747.


The first United States coast to coast
airplane flight occurred in 1911 and took 49 days.


A Boeing 737 weighing 150,000 pounds (68,000
kg) must deflect about
88,000 pounds (40,000 kg) of air – over a million cubic feet (31,500
cubit metres) down by 55 feet (16.75 m) each second while in flight.


The fastest passenger aircraft was the
concorde but its no longer in
service. The fastest aircraft is SR-71 Blackbird i believe. But I heard
somewhere that NASA is working on a hypersonic aircraft.


Birds
were the fastest creatures on Earth until 1919. At that time, pilots
first reached speeds of 190 mph (306 km/hr). Thus, the record for
fastest speeds among birds was broken. The champion bird had been the
peregrine falcon, clocked at speeds nearing 185mph(298km/hr) while
diving. Since then, even cars and trains have beaten that record.


Now, pilots can fly at supersonic (faster than
sound) speeds.
Currently, pilots in the fastest aircraft, X-15A-2, can fly Mach 6 (six
times the speed of sound) or about 4,500 mph (7,000 km/hr).
