PPT-Development of Aerodynamic Forces

Overview Streamline Patterns Review Pressure Patterns Understanding how lift is Generated Streamline Review Streamline Definition A streamline is a path traced out by a mass less particle moving with the air flow. Aerodynamic forces generate a twisting moment which cause the gyroscope to precess and to move on a circular path Let us examine the forces acting on a boomerang of radius The centre of the boomerang is moving at a constant forward speed and the bo By:.

Warm-Up – . 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 radio-controlled 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motion results an uncomfortable aerodynamic behavior, conventional aerodynamic theories and analysis methods are no longer applicable on FMAVs.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.. :.
