Abstract The jet of a microquasar interacts with the interstellar medium, generating characteristic signatures that may unveil important properties of the compact object. For High Mass X-ray Binaries (HMXBs), the presence of the OB type companion star should be taken into account in studying the interaction of the jets with the ambient medium. The strong wind from the companion star dominates in the circum-binary environment, forcing the jet to be bent with characteristic inclination angle which depends on parameters of the jet and the stellar wind. We perfom 3 dimensional hydrodynamic simulation in order to illuminate the relationship between the angle and the jet power, opening angle, and wind power. In the small jet bending approximation, we derive an analytic solution for the bending angle, which can be used to constrain observational parameters in HMXBs.
