Abstract
This article aims to implement a method of adjusting the azimuth and elevation angles of the uncontrolled rocket launcher, based on Lewis concepts, compatible with the Guará suftware method and validating it through a trajectory simulator. The objective isalso to obtain results that demonstrate the compensation of the wind effect on the trajectory according to the adjustment of the implemented method. The methodology consists in the implementation of a flight simulator for unguided rockets that receives the adjustment value and integrates the trajectory of the rocket to the rocket's impact point, taking into account the effect of the wind. To simulate the motion of a rocket, a mathematical model of the rocket and its subsystems is required. The presented method was obtained in MatLab language and compatible with the method used in simulations by the Centro Espacial de Alcântara (CEA) and it has compensated the effect of the wind onthe trajectory of uncontrolled sounding rockets.
