Abstract
An aircraft turbomachine () comprising a first channel () putting into communication the high-pressure compressor () and a high-pressure turbine (), a second channel () putting into communication the high-pressure compressor and a low-pressure turbine (), the first channel being equipped with a valve (), a third channel () being in selective communication with the first channel via the valve, the third channel being in communication with the low-pressure turbine, the valve having a first configuration in which air circulation in the first channel is allowed and prohibited in the third channel, and a second configuration in which air circulation of the first channel is diverted to the third channel, a control device () being configured to determine an air pressure of the low-pressure turbine and command the valve to cause it to transition from the first configuration to the second configuration depending on the determined pressure.
