Study on key technology requirements analysis for integrity maintenance of typical helicopters

The typical helicopters are the important force in the implementation of three-dimensional assault operations, and play an important role in fire support, three-dimensional supply and comprehensive service support. For the structural form and operational requirements, the use of scenarios facing a variety of low-altitude and ground threats, in the low-altitude ultra-low-altitude low-speed mission of helicopters, which results in its worse service environment and combat environment. By analyzing the threat characteristics of helicopters in combat, the influence of comprehensive protection ability, environmental adaptability and combat injury repair ability on the combat integrity of helicopters in the process of helicopter design use and maintenance is expounded in this paper. The integrity of helicopter use can be ensured by reasonably designing the body structure, improving the survival ability, improving the environmental adaptability of sea, plateau, sand and dust, and establishing a complete battle injury repair ability, which can meet the needs of use.
