This study investigates the aerodynamic performance of an aircraft propulsion system employing two contra-rotating propellers. Contra-rotating propellers, consisting of two coaxial sets rotating in opposite directions, are recognized for their potential to enhance propulsive efficiency, thrust generation, and overall system performance. A multidisciplinary approach is adopted, combining principles of aerodynamics and fluid dynamics with Computational Fluid Dynamics (CFD) simulations to examine the flow interactions between the forward and aft propeller sets. The analysis focuses on the reduction of aerodynamic losses, thrust enhancement, and efficiency gains arising from contra-rotating configurations. Using Ansys Fluent and QBlade software, detailed simulations are conducted to capture the complex airflow fields and assess stability under different operating conditions, including variations in rotational velocity, blade number, and flight regimes. The results provide valuable insights into the feasibility and performance advantages of contra-rotating propellers in modern aircraft propulsion. These findings may contribute to the development of energy-efficient and environmentally sustainable aviation technologies, with promising applications in both commercial and military aviation sectors.
