COMPACT VERTICAL TAKE-OFF AND LANDING (VTOL) AIRCRAFT UNIT HAVING PROPELLER FOR GENERATING VERTICAL LIFT

摘要

A compact Vertical Take-Off And Landing (VTOL) aircraft unit includes a duct fan including a propeller having a rotational axis which extends substantially vertically and discharges air downward to generate thrust sufficient for VTOL, an electric motor disposed above the duct fan and including an output shaft operatively connected to the propeller for rotating the propeller, and a cover disposed above the motor which is configured to support a load thereon. A gap is defined between the cover and the duct fan around an outer circumferential periphery of the aircraft and forms an opening of a primary flowpath for ambient air to the propeller, the primary flowpath for ambient air being non-parallel to the propeller's rotational axis.
