Blade Off Test
The blade-off test or blade-out test is a test that is carried out on turbofan engines. At full speed, a fan blade is blasted off to test the behavior of the engine. This must keep the blasted leaf inside the engine cell, cope with the imbalance resulting from the missing fan blade and stop immediately. In this test, the engine is usually completely destroyed, which is why it causes very high costs for the manufacturer. Among other things, however, it is necessary to obtain approval for the engine.
