| Resumo: | The risk involving the use of Unmanned Aerial Vehicles (UAV) has grown directly
with its popularization. It is a global concern of regulatory agencies to reduce these
risks. In Brazil the National Civil Aviation Agency (ANAC) waives most requirements
for UAVs up to 0.250 kg. In this perspective, the present study aims to propose the
design and development of a micro UAV flying wing model with remote or autonomous
piloting capability with low risk of collision to people and facilities (Micro-Brosh). With
a maximum wingspan of 0.30 m and a final weight of 0.160 kg, the Micro-Brosh UAV’s
main feature is its easy and safe operation, being able to be launched manually and with
the realization of landing on grass cover, without causing damage to the aircraft. We
introduce the proposed architectural design, with aerodynamic and performance analyses,
demonstrating parameters such as lift, thrust, drag, stall speed and flight time. In our tests,
the prototype proved to be superior to almost all other UAVs in the literature studied,
except for one that has similar size and flight time characteristics, but with a greater
weight and size than the Micro-Brosh. In all, 6 prototypes were built and analyzed in
more detail, resulting in the final model that was validated through flight tests and bench
tests. In addition to the safety advantages, another important aspect is that the costs
associated with the construction and maintenance of the Micro-Brosh are below $500, a
value considered low in relation to the traditional UAVs surveyed. |
