| Abstract: | This paper numerically investigates flow field interaction and aerodynamic interference characteristics of multilateral‐jets on hypersonic missiles. Three‐dimensional compressible RANS equations coupled with the SST k‐ω turbulence model are solved using the finite volume method. Simulations are conducted for single‐jet, triple‐jets, and five‐jets configurations at freestream Mach 6/8 and angles of attack from −20° to 20°, and a fixed altitude of 20 km. The results indicate that an increase in the number of lateral jets significantly intensifies shock–shock and shock–boundary layer interactions, enlarges flow separation regions, and aggravates nonuniformity in surface pressure distribution, leading to extended downstream interference ranges. Thrust and moment interference factors indicate that multijet configurations effectively suppress the negative control phenomenon, narrow the negative variation range of interference factors, and reduce the sensitivity of control efficiency to the angle of attack. In summary, increasing the number of lateral jets can significantly complicate the flow field and surface flow state, while effectively reducing the risk of "negative control" of the missile control system. This research provides theoretical support and data reference for the engineering application of missile lateral jet control technology. [ABSTRACT FROM AUTHOR] |
