Abstract:

A detailed description is presented of the hot-wall deposition test method for evaluating deposit and degradation characteristics of aircraft turbine engine lubricants at various temperature severity levels. Deposition data are shown for twenty MIL-L-7808- and six MIL-L-23699-type lubricants studied at 350F sump temperature and a range of 510 to 570F heating fluid temperature. Concurrently with test development and lubricant evaluation, the hot-wall test was used in the interrelated studies of test precision, effects of variables, and correlation of deposit ratings with bearing deposition test results.
