Constructal Design And Aeroelastic Stability Analysis Of Hale Aircraft, Ehsan Izadpanahi

FIU Electronic Theses and Dissertations

In the new generation of the Unmanned Aerial Vehicle (UAV), the capability of increasing the flight duration and altitude is the area of interest for designers. The High-Altitude Long-Endurance (HALE) aircraft can fly farther and for a longer period by using high aspect ratio flexible wings. The primary applications and flight missions of this type of aircraft are environmental monitoring, surveillance, and communications. While using high-aspect-ratio, flexible, light-weighted wings improve the efficiency and reduces the required power, it will bring new challenges into the design of the aircraft. One of the major concerns is aeroelastic instability, which can appear as …
