Analysis on water content of product gas in onboard oxygen generation system (OBOGS)

With the need of airplane for long endurance flight, the pilot raises new demand for the gas-water content of the product generated by OBOGS. For this reason, this paper conducted experiments with the system on the two types of oxygen-rich molecular sieves - NaX type and LiX type, which are used currently for domestic OBOGS under different operating conditions, conducted sampling analysis of the bleed air and product gas and obtained H
₂
O content of the product gas, which provides reference for OBOGS researches.
