Design and Aerodynamic Modeling of MetaMorpher: A Hybrid Rotary andFixed-Wing Morphing UAV

2026-03-31

AI Summary

This study addresses the longstanding challenge of reconciling the maneuverability of vertical takeoff and landing (VTOL) aircraft with the cruise efficiency of fixed-wing platforms by introducing MetaMorpher, a morphing unmanned aerial vehicle that synergistically integrates rotorcraft and fixed-wing capabilities. Leveraging a lightweight structure, simplified mechanical design, and a novel wing-folding mechanism, the system enables seamless multimodal flight transitions. A nonlinear segmented-wing dynamics model is developed to accommodate arbitrary force distributions, facilitating modular evaluation of diverse airfoil geometries, mass distributions, and chord lengths on a single platform. Nonlinear flight dynamic simulations implemented in Simulink demonstrate consistent stability across multiple structural configurations, validating the proposed framework as an effective and innovative tool for rapid design assessment.

Abstract

In this paper, we present a generalized, comprehensive nonlinear mathematical model and conceptual design for the MetaMorpher, a metamorphic Unmanned Aerial Vehicle (UAV) designed to bridge the gap between vertical takeoff and landing agility and fixed-wing cruising efficiency. Building on the successful design of the spincopter platform, this work introduces a simplified mechanical architecture using lightweight materials and a novel wing-folding strategy. Unlike traditional rigid-body approximations, we derive a nonlinear flight dynamics model that enables arbitrary force distributions across a segmented wing structure. This modularity allows for testing different airfoils, mass distributions, and chord lengths in a single environment. As part of this work, various flight modes were specifically tested and analyzed in the Simulink environment. The results show that the model behaves predictably under different structural configurations, demonstrating its reliability as a tool for rapid design evaluation.
