Investigation of the Effect of a Flapping Propeller on Its Aerodynamic Performance

This paper focuses on the dynamic effects of flexible propellers F2 class aircraft models. An oscillating propeller affects an engine’s mechanical performance, and this combination has a huge influence model’s flight performance. In first second sections paper, two physical tests that were performed according to test results obtained using CFX numerical model are discussed. The studies for models in show that, when resonant frequencies within operating range aircraft, better parameters achieved. study helps explain effect glass composite’s Young’s modulus behavior conditions stiffness flapping dynamics unsteady aerodynamics.
