Abstract

In order to improve the synthetical performance of fluidic thrust-vectoring nozzle working at high nozzle pressure ratios(NPR),a design concept of a high NPR fluidic thrust-vectoring nozzle is proposed based on dual-throat thrust-vectoring nozzle,and numerical simulations are conducted to investigate the flow characteristics and the effects of key design parameters on nozzle performances.Results show that the proposed design in this paper has a higher synthetical fluidic performance.
