Determination of the force acting on the gas turbine wing in the heat-and-power installations

Abstract

A design scheme for measuring the short-term impulse force acting on the gas turbine wing using the induction method was developed. It was compared with the results measuring the same force using the thermal method. The results of the impulsive force measurement by induction and thermal methods were also compared. After considering the experimental conditions, the thermal method was chosen for experimental studies. It allowed experiments to be conducted with intervals to ensure temperatures of the same magnitude on the surface of the flue gas on the gas turbine wing. The proposed measurement scheme using the induction method was also applied to control and manage the optimal conditions of the gas turbine power-generating device. As a result, a theoretical relationship was obtained as a mathematical relationship between the signal received during the measurement by the induction method and the force to be measured. The conditions for determining the actual value of the force were developed. The error in determining the force acting on the gas turbine wing using the induction method did not exceed 3 %.
