Power withdrawal from a LP body and system for removing debris

A bypass gas turbine engine comprising:

• a low-pressure spool comprising a low-pressure compressor connected to a low-pressure turbine via a low-pressure shaft;
• a high-pressure spool comprising a high-pressure compressor connected to a high-pressure turbine via a high-pressure shaft;
• a low-pressure power withdrawal system comprising an electrical generator and configured to withdraw power from the low-pressure spool, wherein the low-pressure power withdrawal system is configured to withdraw power from the low-pressure shaft using a resistive torque of the electrical generator on a withdrawal command of an electronic control unit to slow down the low-pressure compressor and avoid a surge between the high-pressure compressor and the low-pressure compressor;
• a debris detection device configured to detect a presence of debris between the low-pressure compressor and the high-pressure compressor;
• and
• a debris expulsion system located between the low-pressure compressor and the high-pressure compressor, wherein the debris expulsion system comprises at least one door being opened only when the debris detection device detects a debris.
