The very first powered flight took place back in 1903 when Orville and Wilbur Wright lifted off from Kitty Hawk, North Carolina, aboard the Wright Flyer. The aircraft was powered by a four-cylinder engine with a cast-aluminum block and produced around 12.5 horsepower, while weighing roughly 200 pounds (90 kg), including fuel and coolant. Since then, both aircraft and engine technology have advanced significantly. Over the years, engine manufacturers have introduced successive generations of propulsion technologies, from early turbojets to turbofans, high-bypass turbofans, and, more recently, geared turbofans.
