A Study of Evolution Mechanism and Monitoring Method on Aircraft Sudden Failure

The aircraft sudden failures seriously affect the flight safety of aircraft, and the revelation of the evolution mechanism of aircraft sudden failures is of far reaching importance to the realization of evolution law of sudden failure, and the improvement of the safety and reliability of aircraft. By utilizing the dissipative structure theory, this paper carries out the analysis and research on the characteristics, causes and conditions of aircraft sudden failures from the perspective of mass and energy conversion. Moreover, it also targets on the engine surge, proposes the anti-surge monitoring program by taking the surge margin as monitoring parameters, and verifies the effectiveness and feasibility of proposed method through simulation and actualization.
