INLET PERFORMANCE MEASUREMENT SYSTEM FOR GAS TURBINE ENGINE

摘要

A performance measurement system (56) of an inlet of a gas turbine engine includes a probe strut (58) configured for installation to a case strut (52) of an inlet case (46) of a gas turbine engine. The probe strut (58) includes one or more probes (64) extending therefrom configured to measure one or more characteristics of an airflow past the one or more probes (64), a first attachment point configured to secure the probe strut (58) to a hub portion (48) of the inlet case (46), and a second attachment point configured to secure the probe strut (58) to an outer case portion (50) of the inlet case (46). A data acquisition module (92) is located at a central longitudinal axis of the inlet and is operably connected to the probe (64) to collect sensed data therefrom. The probe strut (58) and the data acquisition module (92) are configured to be installed, removed, and/or relocated without removal of the inlet case from the gas turbine engine.
