MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051779 A) filed by MLR Institute of Technology, Hyderabad, Telangana, on April 23, for 'spring-loaded dual-pin mechanical locking system for wing-to-fuselage attachment in hybrid vtol unmanned aerial vehicles.'
Inventor(s) include Mr. A. Sai Kumar; Mr. Aila Vinay Teja; Mr. Anuragh Mukherjee; and Mr. M. Nitish.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a mechanical locking system designed for detachable attachment of a wing to a fuselage in a multi-mode unmanned aerial vehicle (UAV). The UAV is capable of operating in quadcopter, fixed-wing, and hybrid flight configurations, where structural requirements vary between operating modes. The proposed locking system comprises a spring-loaded dual locking pin mechanism housed within a compact enclosure and operated through a manual pulling member. During installation, the locking pins are retracted to allow positioning of the wing, and upon release, the spring mechanism automatically drives the pins into corresponding receiving openings, thereby securing the wing without the need for tools, electrical power, or complex actuators. The system enables rapid assembly and disassembly of the wing structure, allowing removal of unused aerodynamic components during quadcopter operation to reduce dead weight and induced drag, while ensuring strong structural integrity during fixed-wing and hybrid flight modes. The locking mechanism is lightweight, reliable, and suitable for modular UAV platforms and other detachable mechanical assemblies requiring secure and repeatable connections."
