ABSTRACT:
A duct 11 for an aircraft comprises a flexible panel member 18 which is normally held in a non-fluid conducting condition adjacent the surface of the aircraft body by biass tension means 12, 13, so as to define a substantially continuous surface. On introduction of fluid pressure between the panel and the aircraft body, the panel member is inflated to overcome the biass of the tension means 12, 13, and to expand to a fluid conducting condition of relatively large cross-sectional area, upstanding from the surrounding aircraft surface regions.
