Abstract
A vertical takeoff and landing aircraft system includes a gas turbine engine coupled to a variable pitch propeller. The gas turbine engine is also coupled to a power split device including a first motor generator, a second motor generator, and a planetary module therebetween. The planetary module includes a sun gear, a ring gear, and a planet carrier. The motor generators are coupled to inverters, a DC bus and a battery. The battery is configured to power balance fans disposed on wings and horizontal stabilizers of the aircraft system. The balance fans can be closed off after vertical lift has been achieved.
