The Wright brothers, Orville Wright (August 19, 1871 – January 30, 1948) and Wilbur Wright (April 16, 1867 – May 30, 1912), were American aviation pioneers generally credited with inventing, building, and flying the world's first successful airplane. [3][4][5] They made the first controlled, sustained flight of an engine-powered, heavier ...
Several aviators have been claimed to be the first to fly a powered aeroplane. Much controversy surrounds these claims. It is generally accepted today that the Wright brothers were the first to achieve sustained and controlled powered manned flight, in 1903. It is popularly held in Brazil that their native citizen Alberto Santos-Dumont was the ...
The Wright Flyer was a canard biplane configuration, with a wingspan of 40 feet 4 inches (12.29 m), a camber of 1-20, a wing area of 510 square feet (47 m 2), and a length of 21 feet 1 inch (6.43 m). The right wing was 4 inches (10 cm) longer because the engine was 30 to 40 pounds (14 to 18 kg) heavier than Orville or Wilbur.
His 1881 census status is "Retired Mechanician Inventor of Flying Machines". [10] John Stringfellow died in 1883 at the age of 84 and was buried in Chard Cemetery, Somerset, where there is a commemorative family monument. [11] [12] [13] Stringfellow's first powered flight achievement was referenced in the 1965 film The Flight of the Phoenix.
Richard William Pearse (3 December 1877 – 29 July 1953) was a New Zealand farmer and inventor who performed pioneering aviation experiments. Witnesses interviewed many years afterward describe observing Pearse flying and landing a powered heavier-than-air machine on 31 March 1903, nine months before the Wright brothers flew.
They then measured this ratio by an experiment which involved charging and discharging a Leyden jar and measuring the magnetic force from the discharge current, and found a value 3.107 × 10 8 m/s, [15] remarkably close to the speed of light, which had recently been measured at 3.14 × 10 8 m/s by Hippolyte Fizeau in 1848 and at 2.98 × 10 8 m ...
Another advance was made in 1884, when the first fully controllable free-flight was made in a French Army electric-powered airship, La France, by Charles Renard and Arthur Krebs. The 170-foot (52 m) long, 66,000-cubic-foot (1,900 m 3 ) airship covered 8 km (5.0 mi) in 23 minutes with the aid of an 8½ horsepower electric motor.
A simple electromagnet, consisting of an insulated wire wound around an iron core. An electric current passing through the wire creates a Magnetic field, with a north pole at one end and a south pole at the other. The first application of electricity that was put to practical use was electromagnetism. [18]
