1. Aerofoil Design for Unmanned High-Altitude Aft-Swept Flying Wings
ABSTRACT In this paper, 12 new aerofoils with varying thicknesses for an aft-swept flying wing unmanned air vehicle have been designed using a MATLAB tool which has been developed in-house. The tool consists of 2 parts in addition to the aerodynamic solver XFOIL. The first part generates the aerofoil section geometry using a combination of PARSEC and Bezier-

2. Propeller-induced Effects on the Aerodynamics of a Small Unmanned Aerial Vehicle
Abstract: The present paper has discussed investigations about the propeller slipstream effects on the aerodynamics of a generic unmanned air vehicle platform in the wind tunnel for a broad advance ratio range. The propeller-induced effects for small unmanned air vehicles are more significantly pronounced than general aviation aircraft, because of their high

3. Análise dos modelos para cálculo de níveis de segurança relacionados à operação de veículos aéreos não tripulados. / Analysis of models for calculation of levels of security related to operation of unmanned aerial vehicles.
There are records of the use of Unmanned Aerial Vehicles (UAVs) used for military activities since the beginning of the 20th century. But that is not the only way to use it; the civil environment is also promising as to the use of this kind of aircraft. More studies and validations have to be performed about the alterations in the safety levels with the inte

4. Geração de trajetórias para veículos aéreos autônomos não-tripulados
In this work a study on the problem of the trajectory generation for unmanned aerial vehicles is carried through. The main objective is to provide tools of path planning for aerial robots, taking into account some of its main physical constraints of movement. For this, some of the more used techniques for motion planning of grounded robots are argued initial

5. Algoritmo genético aplicado à otimização de asas de material compósito de veículos aéreos não tripulados / Genetic algorithm applied to optimization of composite material wings of unmanned air vehicles
The advent of the unmanned air vehicles (UAVs) represents a paradigm break in the aeronautical field. The project concepts involved in the development of UAVs are revised and its potential applications are rose. Also the issues related to UAVs operation are assessed and the regulatory questions involved in their certification and integration to the civil air
