METHOD FOR COOLING COMBUSTION CHAMBER OF GAS TURBINE ENGINE BY USING COLLISION JET/EMISSION COOLING METHOD INSTALLED PIN-FIN

摘要

PURPOSE: A collision-jet/emission cooling method is provided to have the structural stability by installing a pin-fin and to increase the whole cooling efficiency by increasing the electric heating area. CONSTITUTION: At least one pin-fins(5) are installed to increase the structural stability and the strength and to improve the cooling efficiency and the life by increasing the electric heating area. The pin-fins are installed in an area having the relatively lower cooling efficiency between injecting holes(2,2'). The pin-fins are closed to an injecting plate(1) and a discharge plate(3) to cool the inner wall of a combustion chamber and to increase the structural strength.
