Yaw Control of a Tailless Aircraft Configuration

摘要

MANYnewaircraft configurations involve a tailless designwithnsweptback wings but without conventional fin and rudder.nRecent examples of such designs are the B-2 and the X-45Cndemonstrator which are mainly optimized for low radar signature.nThe tailless sweptback wing planform was already introduced in then1930s with the sailplane Ho 1 and the powered aircraft Ho 5, amongnmany other designs by the Horten brothers [1]. In those days, thenpurpose of having an all-wing aircraft was reduced drag through anclean design and a not so complicated structural design, among othernadvantages presented by Nickel and Wohlfahrt [2]. In the UnitednStates, Jack Northrop continued with all-wing designs, e.g., thenN-1M, which had split differential drag control surfaces near thenwing tips for creating directional control [3].
