Sir Frank Whittle was an English engineer and air officer in the Royal Air Force (RAF). He was also the inventor of the turbojet engine. During his academic career, Whittle learned the theory of jet engines and gained practical experience during engineering workshops. Before becoming an accomplished pilot, Whittle was selected as an Aircraft Apprentice. While writing his thesis, Whittle formulated the fundamental concepts of a jet engine: these theoretical concepts and a preliminary design led to the creation of the turbojet engine in 1930.
Sir Frank Whittle formed a company named Power Jets Limited along with two retired RAF servicemen to build his engine. Despite no support from the RAF and limited funding for the project, the first prototype of the newly developed turbojet was constructed and tested in 1938. A series of test runs led to its interest among professionals in the field. Contracts start to pour in to build more engines. In 1944, Power Jets Limited was nationalized and capable of meeting the engine demand from customers. Unfortunately, due to severe health reasons, Whittle had to resign from the board in 1946.
