PPT-Aerodynamic research of Flapping MAV

Background Flapping Micro Air Vehicles FMAVs as the most intriguing type of MAVs family have obtained a great interest due to their outstanding efficiency and maneuverability The flapping wings can generate both lift and thrust for an available flight With onboard cameras and sensitive devices these radiocontrolled FMAVs are capable to implement tasks of surveillance exploration and rescue The inherent low Reynolds and unsteady aerodynamics caused by flapping motion results an uncomfortable aerodynamic behavior conventional aerodynamic theories and analysis methods are no longer applicable on FMAVs Ultimately it is always essential to offer the designers and engineers a clear picture about the overall aerodynamic knowledge and useful tool to organize the FMAVs for specific mission objective and flight envelop.

Today, our energy system is based on motion of the cars over the bump that will concentrated on an aerodynamic energy which consist in every city in the world due to the daily increasing in cars amount.. v. ehicles. There is an ever-increasing interest in the field of Micro-Aerial Vehicles (MAV’s) all around the world with recent developments in micro- and . nano. -technologies. MAV’s are defined as small Unmanned Aerial Vehicles (UAV’s) with length scales similar to birds and insects. In addition to comparable physical dimensions, MAV’s also have similar flight mechanisms with those in nature, such as flapping wing propulsion. . 14 1 Julianna Sarolta P Aerodynamic Analysis of Flapping Wing over Fixed Wing Md Jalal Uddin Rumi, Nc Chattopadhyay, and Md Abdus Salam IACSIT International Journal of Engineering and Technology, Vol. 6, No. 2, April 20141 Background. The separated wake at the base of cylindrical bodies presents a number of challenges to aerodynamic designers dealing with similar geometries, such as in missiles or rocket launchers, due to the unsteady and three-dimensional character of the wake..
