Abstract
A hub fairing system () for a stopped-rotor aircraft () having a fuselage () including a hub (). The hub () is mechanically coupled to the fuselage () and to multiple blades () and is rotated by an engine (). A retractable fairing () covers a portion of the hub (). An actuator () is coupled to the fairing (). A controller () is coupled to the actuator () and retracts the fairing (). A method of reducing drag on the aircraft includes transitioning between a rotary-wing mode and a fixed-wing mode. The fairing () is deployed over a portion of the hub () upon the completion of the transition between flight modes.
