Abstract
【解決手段】第1のリング本体端縁2aおよび概してスカラップ型の第2のリング本体端縁2bを有するリング本体と、第2のリング本体端縁に設けられた複数の離間したリングフィンガとを含む、撓みリング。さらに、複数の離間したリングフィンガの各々は、前記リング本体から延在するフィンガ本体を含む。また、複数の離間したリングフィンガの各々に設けられた少なくとも1つのフィンガファスナ開口部をさらに含む。
【選択図】図1
Description
最初に図面の図1から図3を参照して、スカラップ型撓みリングの例示的な実施例を、以降撓みリングと称し、概して参照番号1で示す。撓みリング1は、たとえばチタンなどの金属であってもよいが、これに限定されない。図3に示すように、撓みリング1は比較的高いCTE(熱膨張係数)を有する構造22を比較的低いCTEを有する構造24に結合し、加熱および冷却サイクルの間の、高CTE構造22の低CTE構造24に対する相対的熱膨張および熱収縮を容易にする。低CTE構造24はたとえばセラミックであってもよいが、これに限定されない。高CTE構造22は、低CTE構造24よりも高い熱膨張係数(CTE)を有し得る。
または製造されてもよい。また、航空機94の組立を実質的に容易にするかまたはコストを減じることにより、1つ以上の装置実施例を作製段階84および86の間に用いてもよい。同様に、1つ以上の装置実施例を、たとえば航空機94の運用中に、メンテナンスおよび修理92のために用いてもよいが、これに限定されない。
