A novel MAV with treadmill motion of wing

摘要

The Magnus efect is well known phenomena for producing high lift values from spinning symmetrical geometries such as cylinders,spheres,or disks.But,the Magnus force may also be produced by treadmill motion of aerodynamic bodies.To accomplish this,the skin of aerodynamic bodies may circulate with a constant circumferential speed.Here,a novel wing with treadmill motion of skin is introduced which may generate lift at zero air speeds.The new wing may lead to micro aerial vehicle configurations for vertical take-of or landing.To prove the concept,the NACA0015aerofoil section with circulating skin is computationally investigated.Two cases of stationary air and moving air are studied.It is observed that lift can be generated in stationary air although drag force is also high.For moving air,the lift and drag forces may be adopted between the incidence angles 20 to 25 where lift can posses high values and drag can remain moderate.
