| Abstract: | The test methods of the limit energy of aircraft brake pairs and the confirming methods for their failure were introduced. The test results of the rejected take-off (RTO) of brake pairs were analyzed. It is confirmed that the failure reality for brake pair is the destruction of the friction materials. Therefore, after the limit energy test of brake pairs, three criteria for their failure were put forword. The definition of the maximum brake pressure and the selection of the initial test energy were introduced. The products of USA and domestic substitute of brake pairs for Boeing 737 airplane were tested by these methods. The test results show that the limit energy of brake pairs can be determined by 2 or 3 experiments, thus the test cost is reduced. |
