Manned space flight control mission has the features of technology complexity, high requirement of reliability and real time, enormousness of software and hardware system, and difficulty in flight control cooperation, aiming at which this paper presents an Integrative Flight Control Validation (IFCV) architecture. The validation environment is composed of the actual spacecraft, astronauts, the software and hardware for mission in tracking station and flight control center. Before the launch of manned spacecraft, the IFCV implements comprehensive validation of the interface of spacecraft and ground system, the normal and emergency program for mission, the countermeasures against various faults, and the cooperation process between astronauts, spacecraft and ground system. Through maximizing the scope and reality of flight control validation, the preparative time is shortened, the hidden trouble is eliminated and the success of manned spacecraft mission is guaranteed.
