Beatrice Shilling : l’ingénieure qui a sauvé le Spitfire
Londres – 29 Février 2024 – Pendant la Seconde Guerre mondiale, l’ingénieure britannique beatrice Shilling a résolu un problème critique affectant les moteurs Rolls-Royce Merlin des avions Spitfire.Son invention, un restrictor, a permis aux pilotes alliés de réaliser des manœuvres négatives en toute sécurité, contrant ainsi les tactiques de l’aviation allemande. Cette solution temporaire, mais efficace, a joué un rôle déterminant dans la bataille d’Angleterre et a contribué à la victoire alliée. Découvrez comment son ingéniosité a changé le cours de la guerre.
Here’s a breakdown of the key details from the provided text:
The Problem:
Rolls-Royce Merlin engines (used in planes like the Spitfire) had a tendency to stall when subjected to negative-G maneuvers (like pushing the nose down quickly).
This stalling gave German fighter planes (Messerschmitt BF-109 and Focke-Wulf FW-190) an advantage, as they could escape pursuit by performing these maneuvers that Allied planes couldn’t safely follow.
Beatrice Shilling’s Solution:
Beatrice Shilling invented a “restrictor” (RAE restrictor) to address the stalling issue. It was a temporary fix, not a permanent solution.
despite being temporary,it was effective and popular with British pilots,restoring their combat advantage.
Long-Term Fix & Significance:
The RAE restrictor remained in use until 1943. Eventually, more advanced, pressurized carburetors (initially by Bendix, than Rolls-Royce) were developed, eliminating the need for the restrictor.
According to engineer Keith Maddock, Shilling’s invention was a “winning modification” and crucial to avoiding defeat in WWII.
* her invention solidified the Merlin engine‘s role in helping the Allies win the war.
In essence, the text highlights how a relatively simple invention by Beatrice Shilling played a vital role in overcoming a critical flaw in a key Allied engine, contributing to the war effort.
