MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202641122838 A) filed by Malla Reddy Mr Deemed To Be University; and Dr. K. Kantha Rao on October 14, 2026, for Wing Structure For Ultralight Aircraft With Optimized Material Configuration And Method Of Analysis.
Inventors include Dr. K. Kantha Rao; Dr. K. Vijay Kumar; Dr. Jatoth Heeraman; and Dr. B. Raju.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A wing structure for a radio-controlled aircraft comprises a plurality of wing ribs arranged spaced apart in a span direction and having an airfoil cross-section and fabricated from a first material and at least one stringer extending through the wing ribs in the span direction and fabricated from a second material, different from the first material. The airfoil cross section is chosen among the NACA 0012 and NACA 0016 profile; the first and second materials are selected from aluminum alloy Al- 7075, carbon fiber reinforced polymer (CFRP), and Kevlar. A technique for evaluating the wing structure involves the steps of creating an airfoil profile, generating wing ribs, forming stringer holes, building the structure, conducting finite element analysis and selecting optimal combinations of materials. The best configuration of NACA 0012 airfoil with Kevlar ribs and Al-7075 stringers is a safety factor of around 1.8055.
