Desenvolvimento de um medidor de ângulo de ataque para aeronaves de pequeno porte

Abstract

This work is the first try to attain an operational angle of attack measurement equipment to be installed in small sized unmanned aircraft. It is studied a pressure differential angle of attack sensor in a wind tunnel as sensible element for the proposed device. It is developed a capacitive pressure sensor and its reading electronics as means of turning the proposed device into an electro-mechanical device allowing greater flexibility for use. Among the results there are many performance curves of both sensors and one approach to compress the multipleperformance curves of the angle of attack sensor into a single curve. At the end of the work, it is reached an angle of attack sensor which is linear at the -10 to +10 degrees interval
