When did Frank Whittle file the patent for the turbojet engine concept?

Answer

1930

The foundational design for the turbojet engine, which utilized continuous combustion to generate thrust, was conceived by Frank Whittle while he was still a cadet in the Royal Air Force. Recognizing the importance of securing his novel idea against potential future competitors or appropriation, Whittle moved swiftly to formalize his intellectual property. He accomplished this by filing the initial patent application in the year 1930. This early filing precedes the establishment of Power Jets Ltd. by six years, highlighting the long gestation period often required for truly radical technologies to transition from a conceptual design to physical realization and attract necessary investment and backing.
