Abstract
A system for bleeding air from a core flow path of a gas turbine engine is disclosed. In various embodiments, the system includes a bleed valve having a bleed valve inlet configured to receive a bleed air from a first access point to the core flow path and a bleed valve outlet; and an air motor having a first air motor inlet configured to receive the bleed air from the bleed valve outlet and a first air motor outlet configured to exhaust the bleed air, the air motor configured to pump the bleed air from the core flow path of the gas turbine engine.
Claims19
A system for bleeding air from a core flow path of a gas turbine engine, comprising:
- a bleed valve having a bleed valve inlet configured to receive a bleed air from a first access point to the core flow path and a bleed valve outlet;
- a conduit connected to the bleed valve and configured to convey a pressurized air from a pressurized air source to the bleed valve;
- and
- an air motor having a first air motor inlet configured to receive the bleed air from the bleed valve outlet and a first air motor outlet configured to exhaust the bleed air, the air motor configured to pump the bleed air from the core flow path of the gas turbine engine;
- wherein the air motor is driven by the pressurized air.
A gas turbine engine, comprising:
- a compressor section, a combustor section and a turbine section configured to provide for a core flow path extending through the gas turbine engine;
- a bleed valve having a bleed valve inlet configured to receive a bleed air from a first access point to the core flow path and a bleed valve outlet;
- a conduit connected to the bleed valve and configured to convey a pressurized air from a pressurized air source to the bleed valve;
- and
- an air motor having a first air motor inlet configured to receive the bleed air from the bleed valve outlet and a first air motor outlet configured to exhaust the bleed air, the air motor configured to pump the bleed air from the core flow path of the gas turbine engine;
- wherein the air motor is driven by the pressurized air.
