Air scoop of a system for tip clearance adjustment of an aero gas turbine

摘要

The element has an auxiliary flow channel including a cylindrical orifice arranged in an auxiliary flow channel (3) that extends through an interior lining (1) of a core engine (2). Another tubular flow channel partially surrounds the former tubular flow channel, where the latter tubular flow channel includes a cylindrical orifice that is backwardly offset in the flow direction to the cylindrical orifice of the former tubular flow channel. The cylindrical orifice of the former tubular flow channel is arranged at distance from a wall of the interior lining.
