摘　　要：The successful development of new high performance materials and actuators enable the controlled deformation of aerodynamic profiles for wing like type of structures. This paper presents the studies and conclusions of incorporating a novel morphing rudder for a commercial transport aircraft from the certification conditions perspective. This study provides the static directional-lateral stability evaluation of a two jet engined wing podded commercial transport aircraft when changing its conventional rudder configuration to a more aerodynamic efficient morphing configuration. The lateral force at morphed rudder deflection is set to increase 15% in relation to conventional configuration. The analysis is focused on the engine-out condition at take off which is critical for certification purposes. The analysis concludes the new configuration control surfaces trimming and slippage angle from static directional- lateral stability for this critical load case. The increment on heading moment available is also estimated for the new configuration. This augmentation is translated into minimum control speed requirements and its benefits are assessed.
