Miss Shilling's orifice

Miss Shilling's orifice was a technical device created to counter engine cut-outs experienced during negative G manoeuvres in early Spitfire and Hurricane fighter aircraft during the Battle of Britain. Officially called the R.A.E. restrictor, it was referred to under various names, such as Miss Tilly's diaphragm or the Tilly orifice in reference to its inventor, Beatrice "Tilly" Shilling.
