Due to some failure during the flying of drone systems, it is necessary to design and analyse compact and changeble muti rotor drone systems by using softwares. Multi-engine aircrafts are the mechatronic systems consisting of body frame, electronic control systems, rotors and blades. In the simulations realized in this work special focus has been given to the body frame due to the presence of mechanical and electronic components inside. Analysis of different vibration and force effects occurring on the whole system during the flight with high accuracy is vital for the design process of multi-engine aircrafts. In this work, a novel design procedure has been applied for the multi-engine aircraft structures including 4, 6, 8, 10 and 12 rotors and then the vibration and force effects occurring during the flight have been analyzed. As a result of detailed modal analysis carried out for different vibration frequencies, it has been observed that the vibration frequencies occurring during the flight vary between 7 and 10 Hz. Moreover, from the results obtained, it has been observed that the vibration frequency decreases while the number of rotors increased. As a result of these decreases in the vibration frequency, it has also been observed that the deformations in the body frame increased.
