Abstract

Retractable propulsor assemblies for aircraft are described that generate lift during vertical take-off, hover, and vertical landing. The retractable propulsor assemblies are deployed from a compartment in a fuselage of the aircraft to transition the aircraft into vertical flight, and are stowed in the compartment during cruise flight to reduce aerodynamic drag on the aircraft. One embodiment comprises a method of operating a VTOL aircraft. The method comprises deploying the retractable propulsor assembly from the compartment of the fuselage to provide the lift for vertical flight. The methodfurther comprises transitioning the VTOL aircraft from the vertical flight to cruise flight, and stowing the retractable propulsor assembly in the compartment during the cruise flight to reduce the aerodynamic drag on the VTOL aircraft.

Description

technical field [0001] This disclosure relates to the field of aircraft, and in particular to VTOL aircraft. Background technique [0002] An aircraft that can take off, hover and land vertically is called a VTOL aircraft. VTOL aircraft have one or more rotors that generate vertical lift. Some VTOL aircraft also have fixed wings that generate lift when propellers, jet engines, etc. propel the aircraft forward. When these fixed-wing aircraft transition from vertical to horizontal or cruising flight, the rotors are turned off. However, once the rotor is closed, the rotor, and any support structure associated with it, remains in the airflow around the aircraft, which creates drag. Contents of the invention [0003] A retractable propeller assembly for an aircraft is described that generates lift during vertical takeoff, hover and vertical landing. The retractable propeller assembly deploys from a compartment in the aircraft's fuselage to convert the aircraft to vertical f...
