A flow path is disclosed that is capable of being deployed when needed and stowed in a relatively small space when not in use. The flow path device is flexible and may be made from a variety of materials. In an illustrative embodiment the flow path device is annular and transitions from an ellipsoidal annular shape to a quadrilateral annular shape. A vane box can be disposed at one end of the flow path device. Doors can be coupled to the vane box to cover the flow path device. The doors can be used to provide a structural load path for the flow path device and vane box. The doors and the flow path device can be moved together such that the doors uncover the flow path device as the device is deployed.
