Testing techniques for evaluating experimental gas turbine lubricants in face-riding main shaft jet engine seals at temperatures representative of high mach aircraft have been under development. Using the ASD Seal Rig, repeatable evaluation techniques were developed for MIL-L-9236 type lubricants that were indicative of performance in engines. The present phase of the program is directed towards refining evaluation equipment and preparing the rig for more advanced research work. During the period covered, internal seal head air heating to 1160F, preliminary evaluation studies using 0-60-19 and 0-60-18 lubricants, and engineering features of a new seal head design were investigated. An adaptor to permit the use of the seal head with Erdco test equipment is being designed.
