Abstract

An adaptive duct fan propulsion device includes a nacelle body defining a pathway for air to flow through the nacelle body along a longitudinal axis of the nacelle body; a plurality of primary slats defining a variable geometry inlet duct positioned to admit and guide air into said pathway for air to flow through the nacelle body, each of the primary slats comprising the plurality of slats being movably mounted to the nacelle body and each being independently movable to at least a retracted position associated with a first air inlet geometry having a first maximum diameter and an extended position associated with a second air inlet geometry having a second maximum diameter that is larger than the first maximum diameter; and a plurality of secondary slats disposed to fill a gap between adjacent primary slats when said adjacent primary slats are in the extended position.
