- Abstract:
-
Thermal closure of the engine casing is widely used to minimize undesirable blade tip leakage flows thus improving jet engine performance. This may be achieved using an impingement cooling scheme on the external casing wall, provided by manifolds attached to the outside of the engine. The assembly tolerance of these components leads to variation in the standoffdistance between the manifold and the casing, and its effects on casing contraction must be understood to allow build tolerance to be ...
