Analisys of impact performance of repaired Radome after birdstrike structure

In aviation sector Radome which is located in front of air vehicle, is frequently damaged due to bird strike. Since the damaged area is structurally large it is often repaired instead of replacement. Repair is more efficient in terms of life cycle cost. As a repair method, it is preferred to remove the damaged layer and replace it with a composite patch made of the same parent materials. With this thesis, it is aimed to experimentally examine the performance of the repaired part after being exposed to the same impact again using this method and to measure the availability of airworthiness. Within the scope of the thesis, to verify the performance of the repair, in the first step, tests were carried out by applying an average impact energy of 50 J in a low velocity impact test device. The test specimens were later repaired by means of single scarf technique and the tests were repeated for samples under the same conditions. As a result of this experimental study, it was indicated that the performance of the repair method based on the damage area for the repeated impact simulating bird strike on the same location was found to be very close to original radom part.
