Aerospace Mechanics Division

The Impact Physics Group has been providing test and evaluation services for the development and certification of impact-resistant systems for government and industrial sponsors since 1965.
We have the most diversified indoor impact research facility in the world. Our testing laboratories have 12 gun ranges capable of propelling objects at velocities ranging from tens of feet per second to over 33,000 feet per second.
We routinely perform research and testing in the fields of foreign object damage (FOD), light armor design and evaluation, penetration mechanics, hypervelocity impact testing and analysis, and dynamic behavior of materials.
