Abstract：In this paper, the aerodynamic interference of jet plume to a slender body in subsonic and transonic flow is investigated. Simulation indicates that on the upstream side of the body, jet plume interacting with freestream will cause a more complex flow which induces low pressure area on the slender body downstream of the nozzle. At medium angle of attack or still less, tendency for the interacting effect of CN and mz on the slender body reveals differently. At large angle of attack, the jet nozzle on the upstream side of the slender body still keeps some maneuvering capability to pitching movement. The interference effect varies more violently when the upstream jet is working, while it’s more steady when the down stream jet is working. The intensity of the jet plume interference is greater while the slender body is placed in transonic flow than in subsonic flow.
