What groundbreaking invention did Sir Frank Whittle pioneer in the 1930s?

Okay, let's talk about Sir Frank Whittle and his amazing contribution to aviation. Before Whittle, planes were powered by propeller engines, which had limitations in terms of speed and altitude. Whittle, a British Royal Air Force officer, understood these limitations and began developing the concept of the jet engine in the late 1920s. He patented his design in 1930, and by the late 1930s, he had a working prototype. The jet engine was revolutionary because it used a gas turbine to produce thrust, allowing aircraft to fly much faster and higher than ever before. The first jet-powered flight in Britain took place in 1941, using Whittle's engine. So, while the telephone, computer, and ballpoint pen are all important inventions, they weren't pioneered by Sir Frank Whittle. His legacy is firmly cemented in the history of aviation thanks to his jet engine invention.
