The Aviation industry has come a long way since the invention of the aero-plane by the Wright Brothers. The shape and face of the industry has changed drastically since the time of its inception. With this paper, we intend to give a new perspective to the aviation industry. We try to do so by studying the aerodynamics of birds of prey, one of the most aerodynamically efficient examples created by nature. In this paper, we are publishing the results and inferences of Computational Fluid Dynamics (CFD) analysis on the 3D CAD model of a bird. The birds shortlisted for this exercise were the Red Tailed Hawk, the Peregrine Falcon and the Golden Eagle. The reason for this selection was their remarkable cruising speeds that reiterate the fact that they are natural examples of very high aerodynamic efficiency. Due to its larger size and availability of a clearer body size, shape and geometry, the Golden eagle was chosen as the final bird for analysis. Through this analysis, we are also trying an entirely different approach to designing aircrafts. This paper is the ground work for further research on applications of aerodynamic study of birds for the aviation industry which taking a direct inspiration from the birds of prey.
