Thrust vectoring nozzles can greatly improve aircraft maneuverability and achieve short vertical takeoff and landing. Compared with mechanical thrust vectoring nozzles, fluidic thrust vectoring nozzles have simple structure and better aerodynamic performance. In this paper, the Bypass Dual Throat Nozzles (BDTN) for UAVs with rectangular section (RECT), parallelogram section (PARA) and single saw modified configuration (SAW) is numerically simulated, to study the nozzle outlet temperature field distribution. The numerical simulation results show that the three configurations of Bypass Dual Throat Nozzles can produce effective jet deflection in vectoring state. The length of the nozzle outlet jet core region is the longest rectangular section, followed by the parallelogram section, and the single saw modified configuration is the shortest. Compared with the rectangular section, the exit jet of the parallelogram section and the single saw modified configuration has stronger enrolling effect with ambient air, and the mixing effect is more obvious.
