The oldest method of fluidic thrust vectoring, called the shock vector control (SVC) is quite heavily being researched upon because of its simplicity of installation. However, studies on SVC performance have been limited to single-divergent nozzles (SDNs). In recent times, double-divergent nozzles (DDNs) have gained prominence over SDNs because of their altitude-adaptive capability. The present study deals with the SVC performance of two-dimensional planar DDNs. In particular, the focus is on the influence of the inflection Mach number (IMN) and the length of the base nozzle of a DDN on the performance of the SVC system. Two different IMNs of 1.5 and 1.6 have been considered in the present investigation. In each case, various configurations based on the base nozzle length are studied. The performance of the SVC system on these configurations in terms of the pitch thrust vector angle and the thrust vectoring efficiency have been numerically investigated using commercially available software ANSYS Fluent. 收起
