Miss Shilling's orifice: Miss Shilling's orifice was a very simple technical device made to counter engine cut-out in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain. Beatrice Shilling: Beatrice (Tilly) Shilling OBE PhD MSc CEng (8 March 1909 – 18 November 1990) was a British aeronautical engineer and motor racer. Beatrice Shilling:  During the Second World War, she invented "Miss Shilling's orifice", a small metal disc similar to a metal washer that restricted fuel flow to the carburetor helping prevent engine stall in the Rolls-Royce Merlin engines of the Hawker Hurricane and Supermarine Spitfire fighters, which could lose power or even completely cut out during certain manoeuvres; a significant disadvantage in active service.
