6.The social significance and development situation of FCP was described, the basic principle of present FCP processes and process methods was analyzed, and their existing normal problems were discussed including: requirements for ice pattern, ice pattern making method, properties the mold shell and molding materials should have under the condition of freezing, choice of the materials and their treating process.
7.Several icing parameters were imported to calculate the change of drag coefficient and typical derivatives between clean aircraft and iced aircraft, and the aircraft flight envelope change of iced and un-iced situation was computed, and the small disturbance flight dynamics model was modified to study the effect of the ice accretion on the aircraft dynamics by importing the ice parameter to it, and the longitudinal and lateral stability and the elevator, aileron and rudder step response were also studied and simulated.
