Biefeld-Brown effect (B-B effect for short) refers to the phenomenon that when a high voltage is applied to an asymmetric capacitor, the capacitor generates an additional force. In order to explore the influencing factors and series characteristics of the B-B effect of wire-plate asymmetric capacitors in atmospheric pressure, a set of experimental devices with adjustable parameters was designed. Based on this device, the effects of different wire-plate lengths, power supply types and electrode application modes on the thrust and efficiency of B-B effect are studied. At the same time, the optimal parameters are selected to study the series characteristics. The research shows that the thrust generated by B-B effect is directly proportional to the length of the wire plate. The thrust generated by applying positive emission voltage to the copper wire and grounding the aluminum plate is the largest, and the two-stage series connection can achieve multiple increase of the thrust, with better performance.
