Abstract:

Tests were conducted to measure the chordwise temperature profiles in the buckets of two turbojet engines J47 and J33 subjected to starts, accelerations, decelerations, and shutdowns. The temperature measurements were used in conjunction with analytical procedures based on elastic strain concepts and simple beam theory to calculate thermal strains in the bucket airfoils. The results indicated that the most severe temperature gradients and the highest computed thermal strains occurred at the bucket leading edge during engine starts for both engines. Author
