Engine layouts and associated compartmentalization for aircraft having hybrid-electric propulsion system
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.
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.
