Tailless Aircraft In Theory And Practice Pdf ((full)) -
A conventional wing produces a nose-down pitching moment. A conventional tail produces a balancing nose-up force. In a tailless aircraft, the wing must produce its own balancing force. This is achieved with a —an airfoil whose trailing edge curves upward slightly. This upward curve produces a nose-up pitching moment that can trim the aircraft. However, reflexed airfoils are less efficient than conventional ones, reducing overall lift-to-drag ratio.
