Flow Control on Pantograph with Air Intake and Outlet

This paper provides a means of flow control for rail pantographs by using air intakes and outlets to improve aerodynamic characteristics. The developed panhead allows to air to enter the pantograph at the leading edge of the device and eject from the trailing edge. This design allows for the control of lift force and so improves the interface between the pantograph and wire. Numerical simulation methods are used in conjunction with wind tunnel testing to evaluate the proposed design for pantograph aerodynamics. One issue that researchers had to contend with in this situation was that of sufficient volume of air for jet ejection, the outlet of which is located near to the trailing edge and is connected to a stagnation point by an air tube.
