Abstract
Holographic vibration tests have been conducted to determine the vibration mode shapes of jet engine turbine and compressor blades and airframe panels. Tests were conducted using piezoelectric transducers, electromechanical and electromagnetic vibrators, and acoustic drivers of excitation. Time average holograms were obtained and the vibration pattern used to locate nodes and antinodes and to measure relative displacements.
