What major limitation of propeller-driven aircraft did Sir Frank Whittle aim to overcome with his turbojet design?
Answer
Inefficiency at high speeds
Propeller-driven flight faces significant aerodynamic inefficiencies as aircraft speeds increase. Whittle realized that to transcend these physical limitations and achieve faster flight, the propeller itself had to be discarded. He proposed an entirely new paradigm of thrust generation—the pure reaction engine—which functions by compressing air, igniting it with fuel, and expelling the high-velocity hot gases through a turbine that powers the compressor. This shift moved propulsion away from the constraints of mechanical propellers and enabled the evolution of aircraft capable of high-speed performance.
