The aerodynamic characteristics of pantographs for high-speed trains are a critical factor towards steady current collection. We introduce a new panhead in which air is taken in at the leading edge and ejected around the trailing edge to control lift force. The aerodynamic characteristics of this panhead are estimated using CFD and a wind tunnel experiment, with the results showing that the system is effective in controlling lift force.
