Tester structure for obtaining combustion chamber outlet pressure in complete machine test state

The invention relates to a tester structure for obtaining combustion chamber outlet pressure in a complete machine test state, and belongs to the technical field of turbofan engine combustion chambers. According to the measuring structure for obtaining the outlet pressure of the combustion chamber in the complete machine state, the measuring device extends into the airflow channel in the high-pressure turbine guider through the boss, and it is ensured that the sensing part of the measuring device is arranged in the airflow channel; a high-temperature-resistant sealing ring is arranged in a gap between the measuring device and the boss for sealing, so that leakage of high-temperature airflow flowing through the guider is avoided; the measuring device is arranged at the inlet of the airflow channel of the high-pressure turbine guider, so that the airflow is prevented from forming an airflow angle after flowing through the channel in the guider, and the measurement result is prevented from being influenced.
