1. A system, comprising:
a propeller comprising a propeller blade having a channel extending from an ingress aperture to an egress aperture along a longitudinal axis of the propeller blade; and
a cowl configured to removably couple to the propeller and an electric motor and form a seal between the cowl and the electric motor to capture heated air exuded by the electric motor, wherein:
the cowl comprises an air duct configured to direct the heated air into the channel to deice the propeller blade when the cowl is coupled to the propeller and the electric motor; and
the heated air is allowed to dissipate from the electric motor when the cowl is removed and the propeller is coupled to the electric motor.
