Direct Force Control of a Rudder with the Action of a Coplanar Waveguide Product Microwave

We investigate the distribution of electromagnetic body force in a fluid boundary layer produced by a coplanar waveguide(CPW)and focus on the fluid dynamic control effects of a rudder.The electromagnetic body force along the CPW direction can be created by the mutual coupling of landscape orientated electric and magnetic fields.With CPWs arranged on the rudder's surface,a direct-force-control rudder can be realized by adjusting the microwave sources.It is also found that a streamwise microwave electromagnetic body force can markedly enhance lift force and suppress rudder vibration,thus improving response time lag significantly.Furthermore,navigation stall caused by a large angle of attack can be avoided.
