AI Technical Summary

Technical Problem

Existing aerodynamic elements made from polymer-composite materials suffer from low profile rigidity and poor load-bearing properties under high-speed pressure, affecting their aerodynamic quality and manufacturing efficiency.

Method used

The use of a thermoformed polymer filler with transverse folds oriented along air flow lines, integrated with a longitudinal load-bearing element, enhances the rigidity and load distribution of the aerodynamic element, using thermoplastic polymers like PET, PC, or PMMA, and connecting the skin, filler, and side member into a monolithic structure through gluing or soldering.

Benefits of technology

This approach improves aerodynamic efficiency, increases profile rigidity, and enhances load distribution while maintaining ease of manufacture, resulting in a lightweight, strong, and cost-effective design.

Abstract

The utility model relates to aerodynamic elements of aircraft and can be used primarily in the design of unmanned aerial vehicles (UAVs), as well as in manned aviation and other areas requiring lightweight and rigid structures. The proposed aerodynamic element includes: a skin made of sheet thermoplastic polymer; a folded load-bearing element made of the same polymer using vacuum thermoforming with folds oriented along the flow lines of the high-speed air pressure; and a longitudinal element. The skin, folded load-bearing element, and longitudinal element are connected by gluing or soldering into a single load-bearing structure. Polyethylene terephthalate (PET), polycarbonate (PC), or polymethyl methacrylate (PMMA) can be used as the thermoplastic polymer. The aerodynamic element can be integrated into the structure of the wing, empennage, or nacelle of the unmanned aerial vehicle.
