#P51Mustang #WWIIAviation #AircraftEngineering How did the P-51’s four-blade propeller turn Merlin power into 437 MPH? The answer was more than just adding another blade. Discover how the Hamilton Standard Hydromatic propeller helped the P-51 Mustang absorb the Merlin engine’s massive horsepower, reduce wasted power, and convert it into high-altitude speed. We break down the engineering, propeller physics, torque problems, and wartime solutions that helped make the Merlin-powered Mustang one of WWII’s most famous fighters.
