The Rudlicki Vee Tail: A Novel Arrangement by which a Single Set of Surfaces Operates as both Elevators and Rudder

THE Rudlicki vee tail is the invention of M. Georges Rudlicki, Technical Director of E. Plage i T. Laskiewicz, the Polish aircraft constructors, in Lublin. This revolutionary arrangement of the tail surfaces offers several interesting advantages and overcomes some of the inconveniences of the conventional form of tail. For military aircraft it is particularly advantageous, as it gives better visibility towards the rear and permits a gunner to defend himself better from the back. Requiring a smaller area to give the same effect as a normal tail it weighs 35 per cent less and by the consequent reduction of drag slightly increases the speed of an aeroplane. In wind‐tunnel experiments and in actual flight, it has proved to be at least as efficient as the conventional form.
