Scientists and researchers have been interested to plasma actuators, especially corona plasma actuators as propulsion system, due to their low power consumption, no moving part, silent, high efficiency and infrared waves. An example of corona discharge applications is lifters. In this research, triangular, square and three sides’ with a common vertex models with a common vertex were designed and built. Then, the parameters of electric power, effectiveness coefficient and thrust in the discharge of positive and negative coronas were investigated in the experimental study. The results of the research show that in all three models, the relationship between voltage changes and thrust in positive and negative coronas is almost linear, and increasing the amount of voltage causes an increase thrust. But the relationship between voltage and electric power in all three models in positive and negative coronas is parabolic. The highest amount of thrust in both positive and negative coronas was related to the square model and then the three sides’ model with a common vertex. Finally, the highest effectiveness coefficient in the positive corona is related to the square model and then the three sides’ model with a common vertex, and in the negative corona, it is related to the square model and the triangular model, respectively.
