DETERMINATION OF THE MECHANISMS GOVERNING THE INFLOW OF MOISTURE PAST A ROTARY SEAL

Abstract

The design of an experiment to verify the mechanisms governing the transpor of moisture past a rotary seal is described. The mechanisms were determined after extensive search of technical literature and consultations with persons knowledgeable in the field of water vapor and related phenomena. Nonexistence of suitable testing facilities required the design and development of special equipments necessary to conduct the experiment. These equipments included special moisture sensors with associated indicating device and suitable sensor calibration means; leakproof chambers for simulating fire control instruments; means for simulating various modes of rotation; and a constant temperature environ mental chamber. The testing facilities and their state of completion at the end of FY 1962 are discussed. Recommendations to continue the program are made; cost and time estimates for completion of testing facilities and carrying out of experiment are presented.
