The effect of external casing impingement cooling manifold standoff distance on casing contraction for thermal control of blade tip clearance

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 t...
