Research on correlation of sudden failure of aircraft with human-machine-environment

Research on the correlation of the sudden failure of aircraft with the human-machine-environment has important meaning to know the sudden failure mechanism of aircraft and reduce or eliminate the disaster accidents. In this paper, the feature on sudden failure of aircraft, the forming reason of sudden failure, the spreading way of sudden failure and correlation on sudden failure of aircraft with human-machine environment are researched. At the same time, the relationship model on sudden failure of aircraft with human-machine environment is established, and monitoring module on aero engine in-flight shutdown is designed and it is simulated. Results show that sudden failure of aircraft is a synthetic action result on various factors with human-machine-environment, and it has an evolvement process from gradient to catastrophe and from slight to abrupt. If only the evolvement information of sudden failure can be caught in time and the correspondent measure can be adopted, the emergent fault may prevent and disastrous trouble may reduce.
