Winning the Battle of Britain with Miss Shilling's Orifice

By Gilles Messier

When the throttle is opened, more air is drawn into the engine and the air velocity in the manifold increases. Of course, Miss Shilling’s Orifice was only ever intended as stopgap solution, and eventually all Merlin-equipped fighters were fitted with new Bendix pressure carburetors which did not rely on gravity to operate. And of course, today this same idea is used all over the place in various wireless technologies. As noted, in the end, Hedy’s unrealized contribution to World War II and wireless technology lay dormant for many years. She didn’t invent wireless itself, as you’ll often read, but she did patent an idea with huge potential.
