In order to evaluate complex system in selection of aircraft scheme, the evaluation method based on cloud model was utilized. This paper analyzed the evaluation steps based cloud model. Because of imprecision in judgment from cloud model figure in past, the measurement method of cloud comparability was introduced to judge which rating the evaluation result belongs to. Finally, the application in the...
The influence of pilot error and aircraft failure on the safety of civil aircraft is investigated in this paper. Based on the human-machine system modeling technique, the modules in the pilot-aircraft system failure mode are built using objective-oriented technique, and the software system of civil aircraft safety evaluation is developed. A practical example of flight accident shows that the simulation...
In order to investigate the dynamic characteristic of the aircraft with forward swept folding wing, the finite element model of the forward swept folding wing was modeled in the commercial finite element analysis software MSC Patran, and the corresponding modal analysis was performed using the SOL 103 solution sequence in the MSC Nastran. The influences of folding angle, stiffness of the inner hinge...
