Abstract
A flap to seal retaining apparatus for providing retention between adjacent longitudinally extending seals and flaps in an aircraft gas turbine engine axisymmetric vectoring nozzle. The retaining apparatus provides a channel having transversely extending channel walls mounted on the flap. A retaining lug supported from the seal is disposed within the channel and a positioning device is provided to maintain the retaining lug within the channel when the adjacent seal and flap are skewed with respect to each other. The positioning device provides the lug with a two degree freedom (2DOF) of motion with respect to the flap within the channel.
