Chaparral Weapon System Blast Protective Coating Investigation

Abstract : The purpose of this report is to present the results of the work performed to date directed towards developing a coating to protect the Chaparral Fire Unit from the detrimental effects of the Sidewinder exhaust plume. The results of the environmental and design loads testing on 34 potential coating systems have indicated that seven of these materials can pass the Chaparral requirements. It should be noted that these seven coatings have yet to pass the jet erosion test. The successful coatings included: Phenolics, butadiene acrylonitrile rubber, epoxy-polysulfide, epoxy-nylon and epoxy-urethane formulations.
