FTT’s Structures Group supports our Integrated Product Teams with structural design or analysis, depending on project requirements. Our structural engineers design tools and use best-practice methods to ensure the accuracy of our analyses while compressing schedules. We offer “cradle-to-grave” services for turbomachinery components, including design and analysis, component or engine testing, manufacturing, and field support. Our facilities include state-of-the-art equipment for testing, such as low- and high-frequency shakers, laser holography, and a SPATE infrared camera.
