Abstract: This paper examines an Adaptive fault tolerant flight control for an aircraft that experiences structural damage. A damage degree is introduced for parameterization of the damaged aircraft dynamics. Demonstrating of the damaged flight dynamics and control configuration is presented by following numerical examination of a Boeing 747-100 aircraft model. Here a damage tolerant control framework is introduced for aircraft suffering with vertical tail damage. Model Reference Adaptive control (MARC) procedure is used to address the stability recuperation and robustness of performance in keeping up safe flight operation of the aircraft. The adequacy of the proposed control approach is approved in examination with a standard Linear Quadratic Regulator (LQR) outline through numerical recreations.
