Desenvolvimento e simulação de um computador de bordo para o Veículo Lançador de Microssatélites (VLM)

Abstract

The objective of this work is to develop and simulate an onboard computer for the Microsatellite Launch Vehicle (VLM). The flight path of the rocket was analyzed using a nonlinear dynamic mathematical model. Using software Matlab R /Simulink R , from MathWorks, with the combination of auxiliary calculations, reference systems and their transformations, the equations of the complete set of six degrees of freedom were obtained. The Attitude Control was embedded using the device myRIO, from National Instruments, to simulate the rocket onboard computer. For a better viewing experience, the simulations were displayed on FlightGear flight simulator with the support of MATLAB’s Aerospace Toolbox. The simulation calculations were compared with data generated by ASTOS R software. As result, the project requirements of the VLM were achieved, thus the onboard computer produced successfully controlled the vehicle, achieving the desired trajectory and reaching the destination in question.
