[PAR] [TLE] Beatrice Shilling [SEP] Beatrice (Tilly) Shilling OBE PhD MSc CEng (8 March 1909 – 18 November 1990) was a British aeronautical engineer and motor racer.  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. [PAR] [TLE] Miss Shilling's orifice [SEP] 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.  While it was officially called the R.A.E. restrictor, it was normally referred to under various names, such as Miss Tilly's diaphragm or the Tilly orifice in reference to its inventor, Beatrice "Tilly" Shilling.
