    Design and Development of Variable Pitch Propeller
    (UMT, Lahore, 2023) Muhammad Faizan Qureshi, Muhammad Sumair Saeed, Muhammad Usman
    In this project report the history and development of propellers in aviation history has been discussed. For which different types of propellers have been discussed. They may be differentiated according to their assigned airfoil number, number of blades, material type, fixed pitch and variable pitch propellers. Instead of fixed pitch propellers, the variable pitch propellers are of great interest today in the general aviation aircrafts. Due to their optimized performance and better efficient characteristics. Mostly new modern general aviation aircrafts are equipped with variable pitch propeller mechanism, which contributes to better flight characteristics of aircraft. Various types of methods ae currently being used which includes the use of mechanical, hydraulic and electric methods to vary the pitch of propellers. Variable pitch propellers differ from fixed pitch propellers with respect to their construction and assembly. An idea for electro-mechanical pitch changing mechanism has been proposed in this project report. Where by the use of stepper motor and jackscrew mechanism and mechanical linkages interconnected, a pitch can be changed. Autodesk Fusion 360 is used to make the CAD model for the presented idea. The motion analysis has been simulated to analyze and observe the proper working of the model. Calculations have been made to assure the geometry of presented idea. Market survey has been done to make sure the availability of the parts required, and to check whether the project is viable and financially feasible. The ideas shall be implemented later in the Phase-II of the Final Year Project to make it fully operational.
