Abstract: ABSTRACT An architecture for an electric distributed propulsion system includes one or more generators connected to a gearbox, a first and a second plurality of motors connected to the one or more generators, each motor of the plurality of motors connected to a blade to provide thrust, a first and a second power bus electrically connected between the one or more generators and the first and the second plurality of motors, each power bus independent of the other power bus, a first and a second controller independently connected to each of the first and second plurality of motors, each of the first and second controllers serving as a primary and a backup controller to provide redundant control to both the first and the second plurality of motors, and dual channels in communication between pilot input sensors and the first and the second controllers, each channel of the dual channels independent of the other channels, and the dual channels including an additional channel to provide redundant communication to the first and second controllers.

Abstract: A series of heated control sticks for rotorcrafts, tiltrotors, and helicopters. The heated collective and cyclic sticks feature several heater assemblies to provide localized heating for pilots and co-pilots. The heater assemblies are formed from several layers of fabrics and resistive materials designed to generate heat while current is provided to conductive materials in the resistive material. A controller provides individualized control for users to adjust the temperature of various zones associated with either the collective stick or the cyclic stick. The heater assemblies can be installed entirely external to the stick like in a retrofit or partially internally.
