摘要：
A distributed heating system for a power train of a ram air turbine, which ram air turbine has a stowed position and a deployed position, has at least one electrical resistance heater element, with each electrical resistance heater element located proximate at least one respective lubrication surface for the power train; and an electrical controller for coupling electrical power to each electrical resistance heater element when the ram air turbine is in the stowed position and ambient temperature falls below a desired level.
