Highlights

  • New airplane and unmanned aerial system modeling, simulation, and design methodologies are very important in aerospace engineering

  • Both the droop nose leading edge (DNLE) and morphing trailing edge (MTE) optimized airfoils have shown a significant improvement in the UAS-S45 overall aerodynamic performance, while the MTE airfoils increased the efficiency of CL 3/2 /CD by 10.25%, indicating better endurance performance

  • The Nonlinear Dynamic Inversion (NDI)-AW controller was not implemented and tested due to the absence of sensors for the actual surface deflections. As seen in this Special Issue, “Aircraft Modeling and Simulation”, aerodynamics, structures, and controls engineering analyses and experimental tests were presented for different aircraft systems and configurations for aircraft and unmanned aerial systems

Summary

Introduction

New airplane and unmanned aerial system modeling, simulation, and design methodologies are very important in aerospace engineering. Experimental data are usually provided by use of wind tunnel and flight tests In this Special Issue, numerical methodologies for computational fluid dynamics (CFD), structural dynamics, and controls were studied, and their results were compared and validated with experimental wind tunnel data and other numerical methodologies’ results. The aim of this Special Issue was to promote research and development on aircraft modeling and simulation technologies, while addressing their validation with a minimum possible amount of experimental data.
