PANEL FOR TIP CLEARANCE CONTROL

The present invention relates to a panel (1) for tip clearance control formed by: a first perforated sheet (2) adapted for being seated on the turbine casing (20); a second sheet (3) arranged on said first sheet (2) and configured for being attached to the first sheet (2) leaving a gap between both sheets; and a third sheet (4) arranged between both first sheet (2) and second sheet (3) such that respective spaces in fluid connection by at least one hole (4.1) are configured: a distribution chamber (x) and an impingement chamber (Y), both chambers extending from one end of the panel to the other. The panel (1) further comprises a closure element (5) together with a sealing element at one of its lateral ends (1.1, 1.2) for allowing the passage of fluid with another adjacent panel, whereas the sealing element is configured for allowing relative movement between both adjoining panels (1).
