Popis:	This paper discusses the formulation of stress and vibration analysis programs for use on rocket engine turbopump inducer blades. The analytical model is based on the matrix displacement method using discrete, flat triangular elements to define the blade surface. The stress program calculates stress magnitude and distribution caused by pressure loading and centrifugal forces. The vibration program calculates natural frequencies and distribution of relative displacements and stresses at resonance for a nonrotating inducer blade. The capabilities of the computer programs are demonstrated, and experimental static and operational test data indicate that the programs are capable of predicting frequencies, points of maximum stress, and maximum stress levels.
