The present work aims in providing guidelines for the aerodynamic and performance
optimization of fixed-wing Unmanned Aerial Vehicles (UAVs) that operate in the low-speed …

With the increasing interest in wireless communications from solar-powered aircraft-based
high altitude platforms (HAPs), it is imperative to assess the feasibility of their deployment in …

The unmanned aerial vehicle (UAV) is an aircraft without a human pilot, and thus the primary
applications of UAVs are surveillance without human loss. A low altitude surveillance aircraft …

This study presents the conceptual design of a hybrid solar Medium-Altitude-Long-
Endurance Unmanned-Aerial-Vehicle (MALE UAV) designed to perform surveillance-related …

Design, wind tunnel test, computational fluid dynamics (CFD) analysis, and flight test data
analysis are conducted for the propeller of EAV‐3, which is a solar‐powered high‐altitude …

Abstract Multidisciplinary Design Optimization (MDO) enables one to reach a better solution
than by optimizing each discipline independently. In particular, the optimal structure of a …

One of the main problems in micro unmanned aerial vehicles is endurance or flight time
since the general domain aircraft uses conventional fuel, which is a pollutant, has a limited …

Abstract Modular Solar-Powered Aircraft (M− SPA) is a kind of High-Altitude Long-
Endurance (HALE) aircraft which exploits the mission advantage of swarm UAV and the …

This study explores the effects of wingtip connection on decreasing energy consumption and
increasing flight endurance for solar aircraft. The Oswald efficiency factor, induced drag …

During teleoperation of road vehicles, live images from the vehicle are sent to an operator
via a cellular connection, who then inputs his control demands. Time delays resulting from …
