Title:
AIRCRAFT DRAG REDUCTION SYSTEM AND INTERNALLY COOLED ELECTRIC MOTOR SYSTEM AND AIRCRAFT USING THE SAME
Document Type and Number:
Japanese Patent JP2023159233
Kind Code:
A
Abstract:
To provide an aircraft propulsion system adapted to reduce surface friction on at least one portion of an outer surface.SOLUTION: An aircraft may also have an internally cooled electric motor adapted for use within the aircraft. The motor may have a stator toward the center and an external rotor. A rotor structure can be a composite structure that is air-cooled and has an internal grid adapted for airflow. The stator structure may be a composite structure that is liquid-cooled and has an internal grid adapted to allow liquid to flow through. A fluid pump may pump liquid coolant through a non-rotating portion of the motor stator and then pass it through a heat exchanger, and the heat exchanger is partially cooled by air flowing through a rotating portion of the motor rotor. A drag reduction section and a cooled electric motor section can share the same inlet.SELECTED DRAWING: Figure 1B
