Abstract

One of the important issues in the aviation industry is the Stealth of flying vehicles. One of the stealth methods is to reduce the radar cross section of the target body by means of plasma coating and plasma absorption properties. DBD plasma actuators are widely used in flow control; however, this experimental study was designed to assess their effect on the level of radar cross section on flat plate in the setting of different voltages and frequencies. Plasma placement was investigated in two defferent configurations. Results reveal that the number and distance of the plasma actuators as well as their arrangement can influence the radar cross section. The study could eventually achieved 43.37% (~2/46 dB) reduction in radar cross section using DBD plasma actuator in frequency of 6 KHz and best arrangement.
