Abstract
Embodiments of the present disclosure provide systems and methods for averting, shedding, or otherwise managing ice accretions that may develop during flight of an aircraft. Example systems and methods direct oil from a lubrication and cooling path to targeted sections of ice-prone surfaces to manage ice accretion in a way that does not unduly increase the total volume of oil, require larger pumps, or complicate the system.
Claims24
A propeller assembly for an aircraft, comprising:
- a propeller;
- a motor assembly coupled to the propeller;
- a heat exchanger;
- an oil flow path configured to thermally couple the heat exchanger to the motor assembly, the oil flow path comprising a first segment, a second segment, and a third segment;
- and
- a nacelle mechanically coupled to the motor assembly, the nacelle comprising an air inlet configured to direct air into the heat exchanger, the air inlet comprising a lower lip with respect to a forward flight configuration and an upper lip opposite the lower lip, the lower lip being farther from the motor assembly than the upper lip,
- wherein:
- the first segment passes through motor assembly;
- the second segment passes through the heat exchanger;
- the third segment passes along the lower lip, and
- the oil flow path bypasses the upper lip.
