Abstract

A structure (such as a blade) for an energy converting machine (such as a wind turbine), or for an energy consuming machine (such as a helicopter or aircraft), moves (in use)in a surrounding first fluid. The structure has an aerodynamic surface, and a reservoir 147, 148 containing a second fluid, having a density that is at least ten times greater than that of the first fluid. Ducting 112, and valves 122, enable the second fluid to be controllably dispensed through dispensing means (such as nozzles) 117, 119, 120, 137 thereby creating a mechanism for controlling dynamic behaviour of the structure (eg. by boundary layer control, by backward momentum control, by shifting mass control, or by a combination of these modes of control). An air compressor 123, pumps 121, and a fluid producing means 114 may be provided.
