    2021-1-14 · The double divergent nozzle is a type of altitude adaptive nozzle. The double divergent nozzle does not have any mechanical parts, leading to reduced nozzle weight and requires minimum modifications to the existing launch system. The planar double divergent nozzle is a type of double divergent nozzle, having a rectangular cross section.
