Abstract
Official abstract text for this publication.
A power plant a for an aircraft having a hybrid-electric propulsion system including a nacelle body including therein an electric motor directly connected to a gearbox for driving a propeller, wherein the gearbox is connected directly to a heat motor for driving the propeller, and at least one heat exchanger for cooling the electric motor or the heat motor.
First claim
Opening claim text (preview).
What is claimed is: 1. A power plant for an aircraft having a hybrid-electric propulsion system comprising: a nacelle body including therein: an electric motor directly connected to a gearbox for driving a propeller; the gearbox being connected directly to a heat motor for driving the propeller; at least one heat exchanger for cooling the electric motor or the heat motor; and a turbine compressor assembly positioned below and at least partially forward the gearbox. 2. The power plant of claim 1 , wherein the turbine compressor assembly is partially aft of the heat motor. 3. The power plant of claim 1 , wherein, the nacelle body further includes a landing gear section and a powerplant section, wherein the landing gear section is separated from the power plant section by a bulkhead. 4. The power plant of claim 1 , wherein the electric motor is oil cooled. 5. The power plant of claim 1 , wherein the electric motor is located above the heat motor. 6. The power plant of claim 1 , further comprising an oil sump tank located aft of the electric motor. 7. The power plant of claim 6 , wherein the oil sump tank is above the heat motor.
