Military Researchers Work to Keep Sand From Ruining Equipment

Tiny grains of sand can wreak havoc on military engines performing vital operations in the field. As much as one-third of the 8,000 engines in the field are affected by sand. One rotor for a T-700 aviation engine costs $30,000 and its effectiveness can be greatly hampered by sand.

But, researchers are hoping to fix the problem. The U.S. Army Research Laboratory at Aberdeen Proving Ground, Md., has its scientists and engineers creating a coating technology designed to help prevent sand from causing damage to military equipment.
