MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051774 A) filed by MLR Institute of Technology, Hyderabad, Telangana, on April 23, for 'spring-loaded mechanical locking mechanism for detachable integration of a quadcopter frame with a fuselage in a modular multi-mode unmanned aerial vehicle.'
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 spring-loaded mechanical locking system designed for detachable attachment of a quadcopter frame to the fuselage of a modular multi-mode unmanned aerial vehicle capable of operating in quadcopter, fixed-wing, and hybrid flight configurations. The locking mechanism comprises a manually actuated locking pin assembly housed within a spring-loaded enclosure integrated into the fuselage structure. Manual retraction of the locking pin enables installation or removal of the quadcopter frame, while release of the actuation member allows automatic engagement through spring force, thereby securing the frame without the need for tools, electrical systems, or powered actuators. The proposed mechanism ensures reliable structural attachment capable of withstanding vibration and operational loads generated during vertical lift operations while allowing removal of inactive components to reduce structural weight and improve aerodynamic efficiency during fixed-wing flight. The locking system is lightweight, simple in construction, and preferably manufactured using additive manufacturing techniques such as 3D printing, making it suitable for modular UAV platforms and other detachable mechanical assemblies."
