Turbine blade outer air seal |
摘要 |
A BOAS assembly for a gas turbine engine with a full annular impingement ring secured in place above BOAS segments between front and aft full retainer rings and the front and aft hooks on the BOAS segments. The full impingement ring uncouples the impingement ring from the BOAS segments and eliminates gaps for cooling air leakage so that all of the cooling air is used for impingement cooling of the BOAS segments. A long tongue extending from the aft retainer rings guides the impingement ring and the BOAS segments into place during assembly.
