Abstract
A gas turbo set ( ) is equipped with at least a cooling air system ( ). Throttle points ( ) are arranged as throttling points in the cooling air flowpath, for the purpose of defining the cooling air mass flow. Said manifolds are bypassed by bypass lines ( ). Means ( ) are arranged in said bypass lines for adjusting the bypass mass flow. Thus, the cooling air mass flow can be varied without acting on the main cooling air flow as such.
