<p><P>PROBLEM TO BE SOLVED: To provide a TVC device, in which the number of actuators that drive a jet tab can be reduced and the change of a deflection direction of a combustion gas jet flow is suppressed in accordance with a protruding amount of the jet tab into the combustion gas jet flow. <P>SOLUTION: The TVC device includes a jet tab 40 disposed on a rear side of a nozzle 4 in which a combustion gas jet flow blows out, and a drive part. The jet tab 40 includes deflecting parts 41 and 42 disposed to interpose the center axis S4 of the nozzle 4, and coupling parts 45 and 46 coupling the deflecting parts 41 and 42 to each other. The drive part linearly moves the jet tab 40 in such a manner that the deflecting part 41 approaches the center axis S4 and the deflecting part 42 recedes from the center axis S4, and linearly moves the jet tab 40 in such a manner that the deflecting part 42 approaches the center axis S4 and the deflecting part 41 recedes from the center axis S4. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
