摘要 |
<p>Stator vane retaining means such as may be used in a compressor of a gas turbine engine is disclosed. The compressor is the type including a casing with first and second annular members and a plurality of vanes, each vane having a vane axis and a root end for mounting to the casing. The stator vane retaining means comprise a first flange extending radially outwardly from the first member and a second flange extending radially outwardly from the second member. The second flange includes a plurality of radially extending recesses. The flanges are adapted to mate so that the first flange encloses the recesses thereby forming a plurality of radially extending holes. Each of the holes is adapted to receive one of the root ends. The stator vane retaining means may also include a plurality of bolts extending through the flanges and intersecting a cut-out portion of each of the root ends of the vanes. In this manner, radial retention of each of the vanes is provided. In a further form of the present invention, the cut-out portion may be contoured and cooperate with the bolt so as to allow limited rotational motion about the vane axis.</p> |
