The Need
Current small aerial vehicles face significant design constraints when balancing compact storage with the need for sufficient rotor disk area for stable flight. This limitation hinders deployment in critical missions such as emergency personnel transport or humanitarian aid delivery, where portability and rapid deployment are essential. A solution is needed that enables reliable rotor extension without compromising structural integrity or increasing mechanical complexity.

The Technology
This technology, developed by OSU engineers, introduces a novel “scissor-boom” mechanism that enables rotor arm deployment from a compact fuselage while maintaining structural stability during flight. The design uses eight load distribution points to minimize stress on the lead screw and prevent failure. A locking system ensures torque resistance and vertical motion control, while integrated clamps secure the arms in place. The mechanism supports modularity and ease of operation, making it ideal for field deployment.

Commercial Applications
• Portable UAVs for humanitarian relief
• Emergency infiltration/exfiltration drones
• Tactical reconnaissance platforms
• Compact aerial delivery systems

Benefits/Advantages
• Optimized load distribution reduces mechanical stress
• Compact packaging enables rapid deployment
• Modular design supports multi-mission adaptability
• Ease of use
