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.
Claims19
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.
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.
