عنوان مقاله [English]
Recently, a novel technique using dual throat nozzles is introduced for thrust
vectoring applications. The present paper discusses this new technique. All thrust
vectoring techniques are evaluated with some common parameters: nozzle discharge
coefficient, system thrust ratio, thrust vector angle and thrust vectoring efficiency. For a
given micro turbine nozzle geometry, a double throat nozzle is designed using
dimensional scaling or geometrical analogy. Then, by comparing the results obtained
from a designed geometry for discharge coefficient, thrust vector angle and thrust vector
efficiency, the DTN performance is reported. The designed DTN deflected the vector
angle of 18 degrees with the fluidic injection flow rate equal to 10 percent of the primary
