Abstract
This invention covers elements, such as guide walls, shut-off flaps, flow dividers and vanes, arranged on or in flow ducts energized with compressor and/or fan air, where said elements are variably arranged to suit variable operating states. To achieve extremely accurate, light-weight and uncomplicated actuating kinematics, the elements are designed as memory-alloy components or are nonpositively connected to at least one such component, they are at least partially located at one end and they permit of selective deformation in response to operationally induced over-maximum or under-minimum temperature conditions.
