To improve the engine efficiency by increasing the gas temperature, multi-layer cooling passages are applied in new designs of gas turbine blades. As a result, traditional non-destructive methods, which have been applied so far in the production control, became insufficient. The aim of this manuscript is to develop an inspection method for cooling passages of turbine blades, which would be helpful in detecting manufacturing defects of blades and their operational failures. GE v/tome/x/m 300 was applied to conduct dimensional control and check the interior of two types of turbine blades from turboshaft engines. The procedure for selecting X-ray parameters was suggested. The thickness of walls in the selected cross-section was measured with the accuracy of 0.01 mm, and the selected manufacturing defects of cooling passages were identified.
W celu zwiększenia sprawności silników przez podniesienie temperatury gazów, w nowych konstrukcjach łopatek turbin gazowych stosuje się wielowarstwowe zespoły kanałów chłodzących. W efekcie, tradycyjne metody nieniszczące, stosowane dotychczas w kontroli produkcji stają się niewystarczające. Celem pracy jest opracowanie metodyki inspekcji kanałów chłodzących łopatek turbin do wykrywania wad produkcyjnych łopatek oraz ich uszkodzeń eksploatacyjnych. Zastosowano tomograf GE v/tome/x/m 300 do kontroli wymiarowej i sprawdzenia poprawności wykonania wnętrza dwóch typów łopatek turbiny silnika turbowałowego. Zaproponowano procedurę doboru parametrów prześwietlania. Zmierzono grubość ścian w wybranych przekrojach z dokładnością 0,01 mm oraz zidentyfikowano wybrane wady produkcyjne kanałów chłodzących.
