Fixed Wing UAV Testing Series: Results & Performance Comparison

The CSIE team continues its work on developing and optimizing fixed-wing unmanned aerial vehicles (UAVs). Research and testing are being conducted to improve the operational efficiency of the devices.

As a result of remodeling the wing structure and replacing "NACA 2412" with the "MH114" wing, the following results were obtained:

✅ 127% increase in lift coefficient (C_L: 0.293 → 0.665)․ Bigger wing and better airfoil create more lift

✅ 12% improvement in lift-to-drag ratio (C_L/C_D: 13.65 → 15.23)․ Higher overall efficiency—flies farther per unit thrust

✅ Maintained pitch stability (C_m: -0.017 → -0.018)

✅ Enhanced aerodynamic efficiency

1․ More surface area adds drag, but drag per lift improves

2․ The UAV can stay in the air longer or fly faster with the same power while maintaining its original stability and handling qualities

The research and testing were conducted by CSIE team members: Levon Oganesyan, Rafik Simonyan, Yeranuhi Arsenyan, Haykanush Darbinyan and Astghik Hakobyan.
