We present fully three-dimensional magnetohydrodynamic jet launchingsimulations of a jet source orbiting in a binary system. We consider atime-dependent binary gravitational potential, thus all tidal forces that areexperienced in the non-inertial frame of the jet-launching primary. Weinvestigate systems with different binary separation, different mass ratio, anddifferent inclination between the disk plane and the orbital plane. Thesimulations run over a substantial fraction of the binary orbital period. Allsimulations show similar local and global non-axisymmetric effects such aslocal instabilities in the disk and the jet, or global features such as diskspiral arms and warps, or a global re-alignment of the inflow-outflowstructure. The disk accretion rate is higher than for axisymmetric simulations,most probably due to the enhanced angular momentum transport by spiral waves.The disk outflow leaves the Roche lobe of the primary and becomes disturbed bytidal effects. While a disk-orbit inclination of $10\degr$ still allows for apersistent outflow, an inclination of $30\degr$ does not, suggesting a criticalangle in between. For moderate inclination we find indication for jetprecession such that the jet axis starts to follow a circular pattern with anopening cone of $\simeq 8\degr$. Simulations with different mass ratio indicatea change of time scales for the tidal forces to affect the disk-jet system. Alarge mass ratio (a massive secondary) leads to stronger spiral arms, a higher(average) accretion and a more pronounced jet-counter jet asymmetry.
