Recently, a novel technique using dual throat nozzles is introduced for thrustvectoring applications. The present paper discusses this new technique. All thrustvectoring techniques are evaluated with some common parameters: nozzle dischargecoefficient, system thrust ratio, thrust vector angle and thrust vectoring efficiency. For agiven micro turbine nozzle geometry, a double throat nozzle is designed usingdimensional scaling or geometrical analogy. Then, by comparing the results obtainedfrom a designed geometry for discharge coefficient, thrust vector angle and thrust vectorefficiency, the DTN performance is reported. The designed DTN deflected the vectorangle of 18 degrees with the fluidic injection flow rate equal to 10 percent of the primaryflow rate.
