Aerospace

The state of the art in aerospace engineering has been continually accelerated by the development of advanced analysis and design tools. Used in the early design stages for aircraft and spacecraft, these methods have provided a fundamental understanding of physical phenomena and enabled designers to predict and analyze critical characteristics of new design, including the capability to control or modify unsatisfactory behavior.
