We performed fully 3D relativistic magnetohydrodynamical simulation of “stellar wind”-“pulsar wind” interaction in massive binary system, taking into account various possible pulsar geometries (“Frisbees”, “Cartwheels” and “Bullets” – a reference to the direction of the pulsar’s spin, plane of the orbit and the direction of motion), and various wind trust ratios. The resulting intrinsic morphologies, and different lines of sight, lead to significantly different orbital-phase dependent flow shapes. For the case of companion-dominated wind in the “Bullets-Cartwheel” configuration, the tails length – region of unshocked pulsar wind – can change by an order of magnitude over quarter of the orbit.
