| Summary: | Flying like a bird is something that is unachievable even up to this modern era, despite countless trials has been carried out ever since the concept of human flying machine was proposed by Leonardo da Vinci several decades ago. In general, this study is part of the integrated analysis on the possibility of flying like a bird. This study focuses on forward flapping flight and comprises of bird’s wing modeling as well as aerodynamic analysis of flow over a bird wing shaped model. A wing model in flapping flight is simulated by using a justified numerical tool that has been broadly used by industry and academic institution which is ANSYS Fluent. Wandering Albatross with a wingspan of more than 3 meters (Pennycuick C. J., 2009) has been chosen to be used in this study as its wing has favorable aerodynamic characteristic that can be adapted to actual human flying machine. Flow over a two-dimensional circular cylinder is used as a preliminary study before the bird wing shaped model is analyzed. Similar analysis method and models are then used to analyze the bird wing shaped model. Limited by the availability of numerical software, the simulation is done in one way fluid-structure interaction (FSI) with only downstroke motion of the wing is studied. The Wandering Albatross’s wing model simulated has a lift and drag forces of 194.4N and 6.04N, respectively. With the drag force value obtain from simulation, power requirement of flapping flight for the bird is found to be 186.492 W. |
