Abstract

The invention discloses an air inflow pipe used for a model turbine tester. The air inflow pipe used for the model turbine tester comprises an air inflow pressure stabilizing segment and an air inflow switching segment, the air inflow pressure stabilizing segment is connected with the air inflow switching segment, the first end of the air inflow pressure stabilizing segment is provided with a first annular flange protruding out of the pipe in the radial direction, the first end of the air inflow switching segment is arranged to be a first loose flange assembly, and the second end of the air inflow switching segment is arranged to be a fixing and positioning connection piece used for being connected with a test article in a matched mode; the first loose flange assembly at the first end of the air inflow switching segment is clamped and connected to the first annular flange at the first end of the air inflow pressure stabilizing segment; the first loose flange assembly in the slack state and the first annular flange can be rotationally adjusted in the circumferential direction; the first loose flange assembly in the fastening state and the first annular flange are positioned relative to each other. The air inflow pipe used for the model turbine tester and the model turbine tester are fast and convenient to connect and close in installation and match.

Description

technical field [0001] The invention relates to the field of aero-engine test devices, in particular to an intake duct for a model turbine tester. In addition, the present invention also relates to a model turbine tester comprising the above-mentioned intake duct for the model turbine tester. Background technique [0002] Model turbine tester is suitable for aero-engine model turbine performance test. The air inlet pipeline system of the tester is composed of an electric heater, an inlet airflow regulating valve, an air inlet pressure stabilizing section and an air inlet transition section. In order to ensure that the turbine inlet pressure and temperature flow field are uniform, the tester adopts an axial air intake scheme. The flange used to connect the intake pressure stabilizing section of the original model turbine tester with the intake transition section is welded on the intake stabilizing section. When installing the model turbine test piece, first install the exh...
