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 ...
1949: The first airplane powered by a ramjet engine – the Leduc 0.10 – completes a test flight. The ramjet engine was designed by French engineer René Leduc. 1952: The first fuel injection system for a production passenger car – a mechanical injection system produced by Robert Bosch GmbH – is used in the German Goliath GP700 small sedan.
The Wright Flyer (also known as the Kitty Hawk, [ 3 ][ 4 ]Flyer I or the 1903 Flyer) made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane —on December 17, 1903. [ 1 ] Invented and flown by brothers Orville and Wilbur Wright, it marked the beginning of the pioneer era of aviation.
Aircraft fuel system. An aircraft fuel system allows the crew to pump, manage, and deliver aviation fuel to the propulsion system and auxiliary power unit (APU) of an aircraft. Fuel systems differ greatly due to different performance of the aircraft in which they are installed. A single-engine piston aircraft has a simple fuel system; a tanker ...
The combustion efficiency of most aircraft gas turbine engines at sea level takeoff conditions is almost 100%. It decreases nonlinearly to 98% at altitude cruise conditions. Air-fuel ratio ranges from 50:1 to 130:1. For any type of combustion chamber there is a rich and weak limit to the air-fuel ratio, beyond which the flame is extinguished ...
The only practical solution was for the lubricant to be aspirated with the fuel/air mixture, as in most two-stroke engines. Power increase also came with mass and size increases, [5] multiplying gyroscopic precession from the rotating mass of the engine. Thus aircraft with these engines had stability and control problems, especially for ...
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 ...
Air Commodore Sir Frank Whittle, OM, KBE, CB, FRS, FRAeS [1] (1 June 1907 – 8 August 1996) was an English engineer, inventor and Royal Air Force (RAF) air officer. He is credited with co-creating the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention which was technically unfeasible at the time.
