Embodiment Construction
[0050] In the following description, the terms inner and outer refer to an orientation relative to the axis of rotation of the turbomachine. The axial direction corresponds to a direction along the rotational axis of the turbomachine. The radial direction is perpendicular to the axis of rotation. Upstream and downstream refer to the main flow direction in a turbomachine.
[0051] figure 1 A test rig 2 for an engine 4 is shown in a simplified manner, more specifically a test rig 2 for a turbine 4 , in particular for an aircraft turbojet engine 4 . The test stand 2 can accommodate a complete aircraft, or at least a part of an aircraft.
[0052] The test bench 2 forms the infrastructure, forming a structure. It comprises a channel 6 with an inlet 8 and an outlet 10 . The passageway 6 may comprise a corridor 12 which is substantially long and narrow. Its length may be greater than or equal to 60m. The length of the corridor 12 is such that the airflow 14 flows in a straight...
