Studies of the effects of various materials on jet fuel stability were made. Studies of equipment and procedure for rating fuel stability dealt primarily with the JFTOT fuel coker and with methods of polishing heater tubes for use in other fuel cokers. Fuel lubricity was investigated by means of a simulator measuring the starting friction of a valve spool major sources of error have been identified and recommendations made for a minimum redesign. Fuel corrosion inhibitors were evaluated. Short-term studies have been made of analytical methods for fuel system icing inhibitor and oxygen content of fuels, along with investigation of fuel dyes, fuel compatibility of plastics, fuel acid number determinations, and calibration of the water separometer WSIM apparatus. Operation of an existing information retrieval system has been continued, and jet fuel property data from world-wide procurement processed and analyzed.
