    • A sealing arrangement for a stator shroud segment is provided that includes a resilient seal to reduce air leakage and improve turbine engine efficiency. The stator shroud segment includes an outer shroud having a leading edge groove and a trailing edge groove, and a plurality of inner shrouds each having a leading edge hook and a trailing edge hook. The leading and trailing hooks of each of the inner shrouds are respectively engaged with the leading and trailing edge grooves of the outer shroud so as to connect the inner shrouds to the outer shroud. A resilient shaped seal is located on a leading edge hook of the inner shroud so as to be between the leading hook and a retaining ring that contributes to holding the inner shroud in place.
