A shroud (36) circumferentially surrounds at least a portion of the center body (34) to define an annular passage (40) between the center body (34) and the shroud (36). A closed-loop cooling circuit (44) extends inside the center body (34). The method for cooling the nozzle (12) includes a step of flowing a cooling medium (32) through the closed-loop cooling circuit (44) inside the nozzle (12). <P>COPYRIGHT: (C)2012,JPO&INPIT |
