Abstract

Take-offs and landings are critical phases of any flight since they require the best performance of all critical aircraft systems together with good cooperation and performance of the flight crew. Aircraft systems such as flight controls, communications, landing gear retraction, and extension, fuel systems must be effective at the phase of flight. Flight controls enable the flight crew to control the aircraft’s direction and attitude. Secondary flight (Slats and flaps) controls help to argument lift. Aircraft flaps are attachments to the wing trailing edge designed to improve the aerodynamic efficiency of the wing at low speed. Flaps are extended at take-off to enable aircraft to take off at shorter distances. This study presents the design study of the servo valve model for the aircraft wing flap actuation mechanism, which plays a critical role in controlling lift and drag during flight operations. The main objective of this study is to design a servo valve model that accurately represents the dynamics of the servo valve for aircraft wing flap actuation mechanism. The study begins with an overview of the significance of wing flap actuation in modern aviation, emphasizing the need for precise control mechanisms to enhance aircraft performance and safety. A detailed literature review highlights common types of electrohydraulic servo valves existing, their design features, and their advantages and limitations. Also, various electrohydraulic motor and pump- operated system and their limitations established the motivation for a new approach. The mathematical model of the servo valve is derived using fundamental principles of fluid dynamics and control theory. It incorporates key parameters such as flow characteristics, pressure differentials, and response time. The model also addresses non-linear behaviors and feedback loops that arise in practical applications. By step inputs to each component of the servo valve, simulation studie
