  We present fully three-dimensional magnetohydrodynamic jet launching
simulations of a jet source orbiting in a binary system. We consider a
time-dependent binary gravitational potential, thus all tidal forces that are
experienced in the non-inertial frame of the jet-launching primary. We
investigate systems with different binary separation, different mass ratio, and
different inclination between the disk plane and the orbital plane. The
simulations run over a substantial fraction of the binary orbital period. All
simulations show similar local and global non-axisymmetric effects such as
local instabilities in the disk and the jet, or global features such as disk
spiral arms and warps, or a global re-alignment of the inflow-outflow
structure. 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 by
tidal effects. While a disk-orbit inclination of $10\degr$ still allows for a
persistent outflow, an inclination of $30\degr$ does not, suggesting a critical
angle in between. For moderate inclination we find indication for jet
precession such that the jet axis starts to follow a circular pattern with an
opening cone of $\simeq 8\degr$. Simulations with different mass ratio indicate
a change of time scales for the tidal forces to affect the disk-jet system. A
large mass ratio (a massive secondary) leads to stronger spiral arms, a higher
(average) accretion and a more pronounced jet-counter jet asymmetry.
