Para a realiza??o desse estudo foram desenvolvidas tr?s aeronaves, inicialmente uma asa voadora e um multirotor tric?ptero com objetivo de analisar separadamente cada tipo de aeronave, ap?s os testes e an?lises foi desenvolvido um VANT duplamente h?brido, uma asa voadora e um hexac?ptero, propuls?o por motores el?tricos e ? combust?o. A partir dos testes e c?lculos te?ricos da aeronave h?brida observou-se a viabilidade de um novo tipo de aeronave, com caracter?sticas pr?prias, capaz de conciliar as vantagens de dois tipos de aeronaves. / This work aims to present the development of a double hybrid unmanned aerial vehicle (UAV), capable of reconciling the advantages of two types of aircraft (fixed wing and multirotor), using combustion and electric motors for propulsion and in flight support the wing and the multirotor, able to take off and land vertically, to perform slow or stopped flights, also to execute horizontal flight with support by the wing and propulsion by combustion engine that guarantees greater autonomy. In order to carry out this study, three aircraft were developed, initially a flying wing and a tricopter multirotor with the objective of analyzing separately each type of aircraft, after the tests and analyzes a double hybrid VANT was developed, a flying wing and a hexacopter, motor propulsion electrical and combustion. From the theoretical tests and calculations of the hybrid aircraft, the viability of a new type of aircraft, with its own characteristics, was able to reconcile the advantages of two types of aircraft.

Este trabalho apresenta uma breve revisão histórica sobre asas voadoras, aeronaves sem uma cauda ou empenagem convencional. São apresentadas algumas características aerodinâmicas importantes para esse tipo de projeto e quais são os conceitos fundamentais que devem ser abordados pelo projetista. Na sequência é apresentado o software OpenFOAM, usado para simular o escoamento e obter forças e momentos aerodinâmicos, que são então comparados com dados experimentais de túnel de vento. / This work presents a brief historical review on flying wings, tailless aircraft without a conventional empennage. Some important aerodynamic characteristics are presented for this type of project and which are the fundamental concepts that must be approached by the designer. Following is the OpenFOAM software introduced, used to simulate the flow and obtain the aerodynamic forces and moments, which are then compared with experimental wind tunnel data.
