1. Perimeter Protection Framework 2. A surrounding frame forms a barrier between rotating drive components and external objects during flight operations. This design helps minimize contact with obstacles in confined spaces while maintaining sufficient airflow for lift generation. The structure aids in preserving rotor blade integrity during proximity maneuvers near walls or foliage. 3. Tool Installation Process 4. Integrated mounting clips secure the protective device without additional hardware or tools. Alignment features ensure proper positioning around the drive units during attachment. This design enables quick assembly and disassembly cycles to adapt to different operating environments within documented time parameters. 5. Material Composition Properties 6. Made from elastic polymer compounds with shockabsorbing properties. The material retains structural stability even under typical flight temperature variations. This selection ensures consistent performance in environments with light physical contact without compromising weight parameters. 7. Unobstructed Sensory Field 8. The open grid pattern ensures downward visibility for terrain monitoring systems during lowaltitude operations. The configuration minimizes visual obstruction for surface detection sensors while providing physical barrier functions. This balanced approach simultaneously supports obstacle detection and proximity protection during flight. 9. Simplified Maintenance Access
