Abstract

The objectives of the thesis are to determine the aerodynamics performance and aerodynamic load distribution of an aircraft propeller especially Lift and Drag forces. The propeller force provides thrust which is the force created aerodynamically to push the aircraft through the air. Thus, it is important to define the aerodynamics performance of the propeller. This project is carried out by two different approaches which are the Analytical approach and Computational Fluid Dynamic (CFD) simulation using Fluent 6.3 software. Analytical Method using Propeller Blade analysis is one of the most effective methodologies available for determining the Aerodynamic Performance especially Lift and Drag force of a propeller. While the Computational Fluid Dynamic simulation using Fluent CFD software is used to simulate and capturing the aerodynamics performance of the propeller. Through both methodologies, the aerodynamic performance of the propeller was analyzed and compared. Results obtained were tabulated and the corresponding graphs were plotted. Both methods suggest that the Lift and Drag force increase with the increasing of relative velocity. There are several factors that contribute to error between the Analytical method and CFD Simulation. In conclusion, the propeller has less efficiency since the ratio of lift to drag is smaller than recommended ratio which is more than 13 for optimal performance of the propeller.
