Abstract

The invention discloses a blade separator and an engine containment test device, relates to the aero-engine technology field and solves technical problems of a low test success rate and time/effort consuming existing in the prior art. The blade separator comprises an explosive, a storage chamber and a control device, wherein the storage chamber is arranged at a blade tenon outer wall or a groove inner wall of a wheel disc, the explosive is embedded in the storage chamber, and the control device is used for detonating the explosive to separate a blade into at least two parts through explosion of the explosive. The engine containment test device comprises the blade separator. The blade separator and the engine containment test device are used for improving a success rate of containment tests.

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 generated. 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. If the blade breaks at the most dangerous position, you can choose to break at the outermost tongue and groove of the blade, or 80% of a s...
