Method of recognizing violations of normal operation of the helicopter engineering with the use of registration analysis
The article presents the results of a statistical analysis of the changes in the parameters of the aircraft engine and the main rotor of a Mi-8T helicopter when one guide vane is installed at a non-calculated angle, due to the failure of its gas-air path elements. A block diagram of the complex system of automatic recognition of the normal operation of an aircraft engine by its parameters and rotor parameters using regression analysis is proposed. Adequate regression models of the joint effect of the parameters of the aircraft engine and the main rotor on the temperature of the gases behind the turbocharger are obtained.
