The IE incorporates an algorithm of the radial turbomachinery rotor, stress, and modal analysis that can be easily adapted to meet the needs of preliminary design in terms of accuracy and speed of results.

These new theories and tools will substantially increase the efficiency and reliability of radical and mixed flow turbomachinery.
