In this thesis, we examine the use of distributed electric propulsion for thrust vectoring in civil aircraft and analyze its effect on longitudinal stability using analytical and numerical methods. The mathematical model is based on linearized equations of motion and a state-space matrix, with equilibrium determined by the Newton–Raphson method. Using this model, we conduct a parametric analysis of engine tilt angles and assess their impact on the aircraft’s longitudinal stability. The results show that small engine tilts produce a predominantly linear effect, while critical combinations of angle of attack and engine tilt reduce stability.
