Sistema embarcado para análise de vibração mecânica (flutter) e divergência aeroelásticas em aeronaves em escala reduzida.

Abstract

This report is the result of a Senior Design Project developed at the Electrical Engineering Department at Federal University of Campina Grande. The main goal was the design, implementation and testing of an embedded telemetry system to observe and analyze the aeroelastic divergence and flutter on the wings of scale aircrafts built by the ParahyAsas AeroDesign team. A data acquisition system was built to measure the relative air speed and the accelerations on the tip of the wing. The system includes instrumentation modules with differential pressure sensors associated with Pitot tubes and a triaxial digital accelerometer, as well as Xbee wireless transmission and a supervisory interface to observe the tests in real time. To guarantee the reuse of the acquisition system, the embedded software was built using a layered architecture. It was validated the effectiveness of the system in measuring the physical variables associated with the aeroelastic phenomena.
