Abstract:For lack of testing equipments,the testing study on sealing devices of aeroengine at present is difficult to achieve at all operating conditions.An aeroengine seal test rig which is able to simulate the all operating conditions of aeroengine sealing devices was developed,and the static and dynamic tests for a brush seal was carried out on the test rig.The test rig can simulate operating conditions of sealing devices,such as operating temperature,speed and pressure,and can measure the leakage of the sealing devices through static and dynamic tests.As a result,the test rig can provide a basis for the design and improvement of the aeroengine sealing devices.
