Abstract

The foaming properties of lubricating oils for aviation gas-turbine engines were studied experimentally. The dependences of the aviation oil foamability on the air flow and temperature were found. Addenda to the standard method of GOST 21058-75 for more accurate determination of aviation oil foamability were presented. It was shown that the oil-system operating characteristics changed if the oil foaming properties changed.
