CHEMICAL DEICING OF AIRCRAFT RUNWAYS

ALTHOUGH SNOW ACCUMULATIONS CAN BE ADEQUATELY REMOVED FROM AIRFIELD PAVEMENTS BY A VARIETY OF MECHANICAL MEANS, SAFE REMOVAL OF THIN LAYERS OF ICE, WHICH CAUSE DIFFICULTY WITH RESPECT TO AIRCRAFT BRAKING ACTION, IS STILL INADEQUATE. IN ADDITION TO THE USUAL REQUIREMENTS THAT ICE CONTROL CHEMICALS CAUSE MINIMUM DAMAGE TO THE PAVEMENT TO WHICH APPLIED, THE U. S. AIR FORCE HAS IMPOSED SOME QUITE RIGID REQUIREMENTS WITH RESPECT TO STRESS CORROSION. THE VERY-HIGH-STRENGTH ALUMINUM AND LOW-ALLOY STEELS USED IN ADVANCED AIRCRAFT SYSTEMS ARE PARTICULARLY SUSCEPTIBLE TO CATASTROPHIC STRESS CORROSION CRACKING, A MODE OF FAILURE GREATLY ACCELERATED WHEN THE STRUCTURES INVOLVED ARE CONTAMINATED BY SUCH CONVENTIONAL ICE CONTROL AGENTS AS SODIUM CHLORIDE AND CALCIUM CHLORIDE. THIS PAPER DISCUSSES AN EVALUATION OF SEVERAL CANDIDATE DEICING FORMULATIONS WITH RESPECT TO THEIR INCREASING THE STRESS CORROSION SUSCEPTIBILITY OF HIGH-STRENGTH METALS. SPECIMEN PREPARATION , CONDITIONS FOR EXPOSURE, METHODS OF APPLYING STRESS, DATA FOR A NUMBER OF DEICING MATERIALS ARE PRESENTED. /AUTHOR/
