Abstract
【解決手段】ガイドベーン20の翼基端部21と取り付けフランジ31fとの連結部には、翼基端部21に対して翼厚方向両側から接合する一対の分割片34,34を有する連結サポート体33が配置され、翼基端部21の両側には突条21aが形成され、連結サポート体33の一対の分割片34,34には、翼基端部21に形成された突条21aと係合する溝35aが形成され、一対の分割片34,34の翼中央側に位置する翼弦方向に沿う各側縁35b,35bは翼中央に向けて隆起して形成され、側縁35bの先端には面取りが施され、翼基端部21は、連結サポート体33の一対の分割片34,34に翼厚方向両側から付与される締結力により連結サポート体33の一対の分割片34,34間に保持されている。
【選択図】図2
Description
図1〜図3は本発明に係る翼の連結部構造の一実施例を示しており、この実施例では、ジェットエンジンを構成する静翼としてのガイドベーンの連結部を例に挙げて説明する。
なお、複数の動翼10の各チップ間には、振動防止及び空力性能改善のためのチップシュラウドが連結されているが、このチップシュラウドは図1において図示していない。
