Dynamic Experimental Investigations of a Bypass Dual Throat Nozzle
Journal of Engineering for Gas Turbines and Power, 2015The bypass dual throat nozzle (BDTN) does not consume any secondary injection from the other part of the engine, while it can produce steady and efficient vectoring deflection similar to the conventional dual throat nozzle (DTN). A BDTN model has been designed and subjected to dynamic experimental study.
