Use of the methods of the structural programming to form the «reliability» diagrams of the fuel supply system of the gas turbine engines with the control elements failure order of no less than four

The article studies possible options of development of the «reliability» diagrams which take into account the consecutive mode selection of the fuel flow automatic control system which is considered as a system with elements with three conditions. The article contains main concepts of development of an algorithm used to form a column of the high-order matrix of the incompatible conditions defined by the priority of the failure mode vector component of the control system which characterizes position of the fuelling switch at the failure mode condition as «failure». The article considers a possibility to form components of the «reliability» diagrams using the network structure database. A possibility to state a problem and develop the «reliability» diagrams using calculation equipment is studied
