Design of innovative control surfaces of flying wing aircrafts with large ratio aspect

Because the flying wing aircraft with large aspect ratio cancels the traditional stabilizers and control surfaces which are used in traditional configuration, many disadvantages of dynamic characteristic a-rise. The aerodynamics characteristic of the innovative control surfaces which are implemented on the flying wing aircraft with large aspect ratio were introduced, and elevon and split rudder were involved. And the control effects on three axis were analyzed basing on computational fluid dynamics (CFD) method. The concept of control volume was imported to introduce parameters-based method of control surfaces design. The control effect requirements of the control surfaces were also evaluated. The original design of certain aircraft's control surfaces was modified. An practical suit of steps for control surfaces design which can be used in flying wing aircraft with large aspect ratio has been provided.
