Arthur Henry Lefebvre (14 March 1923 – 24 November 2003) was a British scientist and an innovative leader in the science and engineering of fuel sprays and combustion in

gas turbines A gas turbine or gas turbine engine is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: ...

Career

During his career he developed several innovative atomizers, including prefilming (in the 1960s) and effervescent (in the 1990s) designs for aircraft engines. Improvements in atomization greatly reduced the emissions of

(particulate combustion product) and were instrumental in increasing the reliability of the combustor that was critical to improve the engine robustness. Lefebvre was a pioneer in the development of the jet engine, and arguably one who contributed more as a researcher, designer and educator than any other, except the original inventors – Sir

Frank Whittle Air Commodore Sir Frank Whittle, (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 fo ...
