Publication number: 20240116627Abstract: A VTOL aircraft includes a plurality of lift propellers configured to rotated by lift motors to provide vertical thrust during takeoff, landing and hovering operations. The lift propellers are configured to generate a cooling airflow to cool the lift motors during use. During a cruise operation when the VTOL aircraft is in forward motion, the lift propellers may be stowed in a stationary position. Therefore, the cooling airflow may be reduced or eliminated when it is not needed.Type: ApplicationFiled: February 2, 2023Publication date: April 11, 2024Applicant: Archer Aviation, Inc.Inventors: Karthik Kumar BODLA, Bharat TULSYAN, Christopher M. HEATH, Kerry MANNING, Alan D. TEPE
