تحليل عملكرد مدل متشابه ديناميكي پروازآزاد و توسعه تشابه در شرايط آسيب بال يا سطوح كنترلي پرواز

In this thesis, a similarity-based dynamic model of a light aircraft is designed using similarity relations, followed by the similarity and behavioral adaptation of its automatic pilot system for the main aircraft. In most studies, only the behavioral analysis of the model and the main aircraft has been considered for the design of controllers, establishing similarity, and examining their impact on the behavior of the similar model and aircraft. At the same time, the investigation of damages has often been overlooked. In this project, in order to study damages and their effects on coefficients and ratios, damage is induced on the wing of the model and the main aircraft, and a method is proposed to simulate this damage for them, which leads to the similarity and behavioral adaptation of the damaged state. The impact and performance of the aircraft in undamaged and damaged states are examined and compared. Furthermore, the usefulness of the similarity-based dynamic model for studying the behavior of the aircraft in a damaged state is also eva‎luated. The results demonstrate that the proposed method can have a significant impact, and with the created model, simulate and analyze the behavior of the aircraft in a damaged state.
