How the First Jet Engine Actually Worked | Frank Whittle #shorts #documentary

How did airplanes go from propellers to jet engines? In the 1920s, aircraft engines were becoming more powerful and airplanes were getting faster. But propeller-driven aircraft faced increasing aerodynamic limitations as engineers pushed toward higher speeds. Then a young RAF officer named Frank Whittle began developing a radically different idea. Instead of using an engine to turn a propeller, Whittle proposed pulling air directly into an engine, compressing it, mixing it with fuel, burning that mixture, and sending the hot exhaust gases backward at high speed to create thrust. It was the basic principle behind the turbojet. On January 16, 1930, Frank Whittle submitted his patent application for a revolutionary aircraft propulsion system. But turning the idea into a working jet engine would take years. In 1936, Power Jets Ltd. was formed to develop Whittle's engine. His experimental design used a centrifugal compressor to compress incoming air. Fuel burned inside combustion chambers, producing hot expanding gases that passed through a turbine. The turbine drove the compressor through a shaft, allowing the engine to sustain the process while the remaining exhaust energy produced thrust. Then came the breakthrough. On April 12, 1937, Whittle successfully ground-tested his first experimental gas-turbine engine. Four years later, on May 15, 1941, the Gloster E.28/39 powered by Whittle's jet engine made its historic first flight at RAF Cranwell. Britain had entered the jet age. The basic principles Whittle helped pioneer remain at the heart of modern jet propulsion. Air enters. It is compressed. Fuel burns. Hot gases expand through the turbine. And high-speed exhaust helps produce thrust.
