Questions & Answers

Q: Why did the Spitfire's Rolls-Royce Merlin engine lose power during negative G maneuvers?

The engine's carburetor, originally designed for automobiles, flooded with fuel under negative G forces, causing power loss.

Q: How did Beatrice Shilling's fix, the restrictor, solve the Spitfire's engine issue?

The restrictor allowed just enough fuel to flow through the carburetor, preventing flooding, while maintaining continuous engine power during negative G maneuvers.

Q: Did the German Messerschmitt BF-109 have a similar engine issue?

No, the BF-109 had a fuel-injected engine, which did not suffer from the same power loss problem as the Spitfire's carbureted engine.

Q: How did Miss Shilling's Orifice contribute to Britain's victory in World War II?

By fixing the Spitfire's engine issue, Miss Shilling's Orifice enabled the aircraft to compete on equal footing with the BF-109, improving the Royal Air Force's chances in dogfights.
