Icing Freezing Rain

Icing and freezing rain on aircraft structures and controls represent serious hazards to aviation. Freezing precipitation ads weight, inhibits the movement of navigation mechanism and increases drag. Rotor blades, wings and flaps that suffer an accumulation of frozen rime and glaze present potential failure and catastrophe.

On oceangoing vessels, icing, freezing rain conditions impede the performance of antennas, optical devices, meteorological instruments and other topside equipment. The accumulated icing on ships has the potential to decrease the ships stability by raising the center of gravity. The protective enclosure of any other critical equipment that will routinely be left outside in a harsh environment or that will be subjected to such conditions as a result of sudden failure, needs to be tested for the effects of icing freezing rain.

National Technical Systems provides climate induced icing tests according to Mil-Std-810, and RTCA/DO-260 and will tailor testing to the conditions anticipated in the life of the product. If requested, we will evaluate de-icing methods, and rank their effectiveness.

Facilitating the operation of your equipment during the icing, and de-icing tests, NTS can provide large, 15' x 25' x 25' walk in chamber safe for habitation, with a capability of °100F to +250°F. A number of smaller chambers serve the same function for components and subassemblies; NTS personnel will provide the hook ups for remote controls to operate your equipment during the test, should your test be functional.
