Description

technical field

[0001] The invention relates to the technical field of aeroengines, in particular to a blade separation device and an engine containment test device provided with the blade separation device. Background technique

[0002] The aero-engine blade inclusive test is one of the important tests that must be carried out when the engine type is finalized or airworthiness certification is obtained. This test is used to judge whether the aero-engine meets the inclusive requirements after the blade falls off. Containment refers to the containment performance of the engine structure to the debris formed after the blade is produced. A well-contained engine is more resistant to debris penetration.

[0003] When carrying out the blade containment test, certain test conditions need to be met, and the test conditions include:

[0004] 1. The blade breaks at the most dangerous position, you can choose the outermost tongue and groove of the blade, or 80% of the single blade of...
