Drag-rudders and a set of elevons are usually used as control surfaces for flying-wing aircrafts,which are quite different from conventional ones. To clarify the influences of faults on the control efficiency of flying wing aircrafts,accessible moment set method is applied,based on the control coupling characteristics in consideration. Rudder-trapped,rudder-loosening and rudder damage are taken as the objects. The differences between new type control surface faults and the conventional control surface faults on the control efficiency are summarized. According to the research,elevon failure has a great influence on roll and pitch control capability of the aircraft with flying wing layout,and elevon stuck failure has the greatest impact on efficiency. Drag-rudder still retains certain amount yaw control ability after failure,and drag-rudder failure causes a significant influence on the pitching control ability. Besides,loosen of drag-rudder has the greatest influence on yaw control ability.
