Green Maintenance Technology for Large Area Damage of Composite Tail Rotor Blade

Based on the analysis of the damage location, damage size, product layering structure, and internal filling structure of the composite tail rotor blade, the damage maintenance technical scheme was initially determined. Combined with the comprehensive performance test after maintenance, to determine the use of an enhanced repair method, special repair tooling was used to repair the product, which can repair the product fault, and the fatigue life of the product can be restored to the initial state of the product. The repair cost is low, the product performance after repair is excellent, and the repair pass rate for this kind of failure is 100%, enabling the green composite tail rotor blade repair to solve the bottleneck problem in composite blade maintenance.
