This research work focus on the stability part of a tilt rotor unmanned aerial vehicle. The work starts from the definition of tilt rotor mechanism and proceeding to the design of the same. Thrusters have been used to fly this aircraft both in helicopter mode as well as in airplane mode. Tilting the thrusters with servos will tilt the thrust vector associated with the thrusters. Keeping that principle in mind this research work has been carried out. So the positioning of thrusters explained in this paper adds a weight age to this research work. Rectangular wing is used to generate lift during the airplane mode made the design simple as well as effective. The major step taken for the stability of the aircraft in helicopter mode, airplane mode as well as in the transition period is the design of the tail. The tail is designed in such a way that it can counteract any disturbances occurring in horizontal plain or vertical plane. The design of the tail makes this research paper work unique. Servos are used to tilt the whole tail which consists of horizontal stabilizer as well as vertical stabilizers. To define the stability this research work considered the contribution of the wing, fuselage and tail which together will define the longitudinal stability of the aircraft. The results after the stability calculations are more satisfying. From the results this research work concluding that the designed tilt rotor unmanned aerial vehicle will be stable in its flight.
