Spatial structure of highspeed flow exhausted from dual stream jet nozzle

摘要

This paper presents an experimental study of spatial stationary structure of the high-speed jet flowing from the dual-stream jet nozzle which interior structure is taken into account. The research was made for transonic gas dynamic regime of the flow. The influence of internal nozzle design elements such as supporting pylons and pressure pipes on the pressure distribution along the azimuth in the outer and inner flows of the dual-stream jet nozzle is determined. The formation of significant azimuth disturbances in the outer contour of the nozzle is revealed.
