INITIAL CALCULATIONS FOR THE THEORETICAL INVESTIGATION OF THE HIGH SPEED LOCOMOTIVE E103

PILOTRECHNUNG ZUR THEORETISCHEN UNTERSUCHUNG DER SCHNELLFAHRLOKOMOTIVE E103

Pressure and velocity distributions at the surface of a simplified model of the high speed locomotive E103 of the German railways were calculated using the panel procedure for compressible frictionless flow with sideslip angles of 0, 5, 10, 15, 20, 25, and 30 deg. The force and moment coefficients were obtained by integration of the pressure distribution over the vehicle surface. The overlap principle was used to develop a procedure with which the velocity and pressure distribution and the coefficients for random sideslip angles can be calculated from only two sideslip angle values obtained with the panel procedure.
