Abstract

An electromechanical system for a gas turbine engine includes a mechanical component located at a first side of a firewall of a gas turbine engine, and an electrical motor located at a second side of the firewall and configured to drive the mechanical component. The electrical motor mechanically connected to the mechanical component through a firewall opening in the firewall, the first side having a higher operating temperature than the second side. An electrical connection extends between the mechanical component and the electrical motor via the same firewall opening.

First claim

The invention claimed is:

1. An electromechanical system for a gas turbine engine, comprising:
a mechanical component disposed at a first side of a firewall of a gas turbine engine, the firewall extending between a core flowpath and a bypass flowpath of the gas turbine engine;
an electrical motor disposed at a second side of the firewall and configured to drive the mechanical component, the electrical motor mechanically connected to the mechanical component through a firewall opening in the firewall, the first side having a higher operating temperature than the second side; and
an electrical connection between the mechanical component and the electrical motor via the same firewall opening.

2. The electromechanical system of claim 1 , wherein the electrical connection includes:
a first connector portion disposed at the electrical motor; and
a second connector portion disposed at the mechanical component configured such that installation of the electrical motor and the mechanical component at the firewall opening results in engagement of the first connector portion with the second connector portion to complete the electrical connection through the firewall opening.

3. The electromechanical system of claim 1 , further comprising a drive shaft to mechanically connect the electrical motor to the mechanical component.

4. The electromechanical system of claim 1 , wherein the electrical connection is configured to communicate data regarding performance and/or operating conditions of the mechanical component between the mechanical component and an electrical controller disposed at the second side of the firewall.

5. The electromechanical system of claim 4 , wherein the electrical controller is operably connected to the electrical motor to control operation thereof.

6. The electromechanical system of claim 1 , wherein the mechanical component is one of an actuator, a pump or a valve.

7. The electromechanical system of claim 1 , further comprising one or more of an electrical, optic, electro-magnetic, microwave, radio frequency, inductive, or acoustic connection through the same firewall opening.

8. The electromechanical system of claim 1 , wherein a relative installed position of the electrical motor and the mechanical component is adjustable by independent movement of the electrical motor and/or the mechanical component.

9. The electromechanical system of claim 1 , wherein the first side has an operating temperature greater than 160 degrees Fahrenheit.

10. The electromechanical system of claim 1 , wherein the firewall is disposed axially upstream of a high pressure compressor section of the gas turbine engine, the first side disposed axially downstream of the firewall.

11. A gas turbine engine comprising:
a high pressure compressor;
a combustor in operable communication with the high pressure compressor;
a firewall extending between a core flowpath and a bypass flowpath of the gas turbine engine, the firewall defining a first side axially downstream of the firewall and a second side axially upstream of the firewall, the second side having a lower operating temperature than the first side; and
an electromechanical system, including:
a mechanical component disposed at the first side;
an electrical motor disposed at the second side and configured to drive the mechanical component, the electrical motor mechanically connected to the mechanical component through a firewall opening in the firewall; and
an electrical connection between the mechanical component and the electrical motor via the same firewall opening.

12. The gas turbine engine of claim 11 , wherein the electrical connection includes:
a first connector portion disposed at the electrical motor; and
a second connector portion disposed at the mechanical component configured such that installation of the electrical motor and the mechanical component at the firewall opening results in engagement of the first connector portion with the second connector portion to complete the electrical connection through the firewall opening.

13. The gas turbine engine of claim 11 , further comprising a drive shaft to mechanically connect the electrical motor to the mechanical component.

14. The gas turbine engine of claim 11 , wherein the electrical connection is configured to communicate data regarding performance and/or operating conditions of the mechanical component between the mechanical component and an electrical controller disposed at the second side of the firewall.

15. The gas turbine engine of claim 14 , wherein the electrical controller is operably connected to the electrical motor to control operation thereof.

16. The gas turbine engine of claim 11 , wherein the mechanical component is one of an actuator, a pump or a valve.

17. The gas turbine engine of claim 11 , further comprising one or more of an electrical, optic, electro-magnetic, microwave, radio frequency, inductive or acoustic connection through the same firewall opening.

18. The gas turbine engine of claim 11 , wherein a relative installed position of the electrical motor and the mechanical component is adjustable by independent movement of the electrical motor and/or the mechanical component.

19. The gas turbine engine of claim 11 , wherein the first side has an operating temperature greater than 160 degrees Fahrenheit.
