Safety Assessment Method of Rotor System Based on Analytic Hierarchy Method
With the progress of the times,the helicopter rotor system has gradually diversified,and the demand for helicopter rotor system is becoming more and more complex.In order to meet these different functions and design re-quirements,it is necessary to continuously optimize and improve the original rotor structure,and in this process,it is particularly important to ensure the safety of the rotor system.Therefore,the safety risk assessment of the rotor system has become the first issue that designers need to solve.For this reason,based on the basic conditions of the devel-opment of helicopter industry in China,a safety assessment method of rotor system based on analytic hierarchy method(AHP)is proposed by taking the basic configuration of a helicopter rotor system as an example.In the scheme design stage,the rotor system is decomposed into the bottom layer of the elements affecting safety according to the structural characteristics of the rotor system,and then the influencing factors of each influence element on the decision-making layer are calculated,and then the overall safety of the rotor system is evaluated by fuzzy theory,which provides a guarantee premise for the subsequent field test flight,and also provides a reference for helicopter designer to analyze the safety of the rotor system.
