Nanhai Anuradha Engineering College, Chikhli, Maharashtra, India INTRODUCTION In the early days of aeronautics the flight of birds has changing with time. This unsteady airflow affects the stimulated scientists and engineers in the research and lateral-directional stability characteristics of birds. development of aircraft. Much has been learnt from nature and pioneers in the aeronautical field have CAD, CFD THEORY AND WORKING studied the flight of birds. Birds move from one place 3.1 COMPUTER AIDED DESIGN- to another by driving their wings in air. The motions • CREO Introduction of the bird in the air consist of flapping flight as well CAD technology is very important while designing as gliding and soaring flight. Investigations on the any Product. aerodynamic characteristics of birds have been conducted for a variety of purposes. For example, an Following are advantages of CAD technology: issue is formation flight of the birds as an energy • To increase the productivity of the designer saving mechanism during TI - Evaluation of Ceiling Fan Blade Angle Performance using CFD JF - International Journal of Trend in Scientific Research and Development DO - 10.31142/ijtsrd19015 DA - 2018-12-31 UR - https://www.deepdyve.com/lp/unpaywall/evaluation-of-ceiling-fan-blade-angle-performance-using-cfd-51VNU5fCbH DP - DeepDyve ER -
