초록

A turbofan engine includes an engine core and a ducted fan assembly, with the ducted fan assembly including an annular cowling and a dilating fan duct nozzle. The nozzle includes continuous nozzle sections with intermeshing tiles. The tiles include drive tiles that are pivotal between nominal and dilated positions and driven tiles that intermesh with the drive tiles and shift with the drive tiles between the positions. The intermeshing tiles cooperatively adjust an orifice size of the nozzle by shifting between the positions and thereby affect the thrust...

What is claimed is: 1. A turbofan duct assembly operable to direct a duct flow generated by a fan in a rearward direction into ambient and operable to be powered by a power source, said turbofan duct assembly comprising: a fan duct presenting fore and aft ends, said fan duct configured to surround the fan and extend rearwardly of the fan to the aft end, with the fan duct being operable to fluidly engage the duct flow; and a dilating fan duct nozzle operable to fluidly engage the duct flow discharged from the fan duct, said dilating fan duct nozzle compr...
