Description

technical field

[0001] The field of the invention relates generally to aircraft electrical power generation and distribution systems, and more particularly to possible methods and systems for reducing high pressure turbine stall. Background technique

[0002] At least some known aircraft are powered by two or more high bypass ratio turbofan engines. These engines include fans driven by low pressure spools that provide a substantial portion of the overall propulsion system thrust. The high voltage spool drives one or more compressors and additional thrust is generated by directing the exhaust products in a rearward direction.

[0003] In addition to providing thrust to propel the aircraft and power the aircraft's hydraulic and pneumatic systems, the engines provide electrical power to many aircraft components, including environmental control systems, aircraft computers, hydraulic motor pumps, and / or other motors and electrical devices. One way to obtain electrical power fro...
