Aircraft Gas Turbine Engines #01 - Introduction Part 1
Aero & Air・8 minutes read
Jet propulsion has a long history, from Hero of Alexandria in 250 BC to modern gas turbine engines like those designed by Sir Frank Whittle, leading to the development of powerful engines like the Neen engine used in the Russian MIG 15 aircraft during the Korean Conflict. Gas turbine engines have advantages in compression ratios and mass flow over centrifugal compressors, contributing to their continued advancement.
Insights
- Hero of Alexandria in 250 BC created an early form of jet propulsion by using steam pressure to rotate a sphere, laying the foundation for modern jet engine technology.
- Gas turbine engines, pioneered by Sir Frank Whittle, utilize axial flow compressors, offering superior compression ratios and mass flow compared to centrifugal compressors, driving the continuous evolution of jet propulsion systems.

Evolution of Jet Propulsion Technology
- Jet propulsion is the force generated by fluid under pressure escaping through an opening in the opposite direction, evident in everyday items like lawn sprinklers and rockets.
- Hero of Alexandria in 250 BC created a rear engine using steam pressure to rotate a sphere, showcasing an early form of jet propulsion.
- In 1940, the Italian Caproni CC- flew with a hybrid jet-powered design using a compressor powered by a conventional piston engine.
- Sir Frank Whittle patented his jet engine in 1930, leading to the development of the Derwent engine by Rolls-Royce capable of 2,450 pounds of thrust.
- The Neen engine, with 5,000 pounds of thrust, was developed in response to General Electric's powerful engines, later used in the Russian MIG 15 aircraft during the Korean Conflict.
- Gas turbine engines, like those developed by Whittle, use axial flow compressors with advantages in compression ratios and mass flow over centrifugal compressors, leading to their continued advancement.
