Description

The FARM Rain Erosion/Impact Measurement Lab develops solutions for deficiencies in the ability of materials, coatings and designs to withstand a severe operational environment.

The RF Sensors Division of NAWCAD conduct rain erosion/impact measurements at it's facilities for Antenna and RCS Measurements (FARM). Radome material sample of one inch size is mounted at the end of a 48" aerodynamic steel counterbalanced rotating arm in the FARM's Rain Erosion/Impact Measurement Laboratory. The arm is housed in a 10 Ft. diameter steel chamber and rotated through a controlled density (0.5 - 1.0 inch/hr) and droplet size (2.0 - 2.5 mm) rain field environment at velocities from 300 N mph to Mach 1.8

During the past several yearsthe lab hasconducted rain erosion/impact testing and evaluation of various materials in classes such as: thermosets, thermoplastics, composites, laminates, and elastomeric coatings. Through the utilization of the Rain Erosion/Impact Measurement Laboratory, valuable data has been generatedon mass loss of solid laminates and thermoplastics as a function of rain impact exposure.
