AeroShell Turbine Oil 390 is a 3 mm2/s synthetic diester oil
incorporating a carefully selected and balanced combination of additives to
improve thermal and oxidation stability and to increase the load carrying
ability of the base oil.
Main
Applications -
·
AeroShell Turbine Oil
390 was developed primarily as an improved 3 mm2/s oil for British turbo-jet
engines. AeroShell Turbine Oil 390 is fully approved for a wide range of
turbine engines.
·
More recently, because
of the low temperature characteristics of AeroShell Turbine Oil 390, there is
interest in using this oil in auxiliary power units (APU) in order to overcome
the effects of cold soak. Normal practice is to shut down the APU during
cruise, the APU then experiences cold soak, often prolonged, and when the unit
is started there is considerable difficulty resulting in the unit not coming up
to speed in the given time, thus causing a hung start.
·
In such cases where
the APU is subject to a long cold soak the viscosity of standard 5 mm2/s oils
used in the APU will increase from 5 mm2/s at 1000C to typically 10,000 mm2/s
at –400C. At this much higher viscosity the oil cannot flow easily leading to a
large viscous drag within the APU, thereby contributing to the difficulty in
starting. AeroShell Turbine Oil 390 on the other hand experiences a much
smaller viscosity increase (typically 2000 mm2/s at –400C) with a reduction in
viscous drag which is often sufficient to overcome hung start problems.
·
All experience to date
shows a considerable improvement in cold reliability of the APU when AeroShell
Turbine Oil 390 is used.
