- 航空機エンジンのためのエンジンナセル(10)であって、
対向する軸方向の端部で開口した管状ケーシングを備え、
管状ケーシングは、内壁(12)と外壁(14)を含み、内壁(12)と外壁(14)は、前縁(16)に沿ったフロントエンドと後縁(18)に沿ったリアエンドで互いに接続されていて、前縁(16)と後縁(18)と共に空洞(20)を囲み、
ナセル(10)は除氷手段(22)を備えていて、除氷手段(22)は、氷の形成を防ぐために、少なくとも前縁(16)のゾーン内の、ナセル(10)の壁を加熱するように設計されていて、
除氷手段(22)は、空洞(20)の内部に配置された多孔質材の分離部材(22)を含み、空洞(20)を、内壁(12)と分離部材(22)との間にある内側の空洞(20a)と、外壁(14)と分離部材(22)との間にある外側の空洞(20b)とに分割し、前縁(16)と接触する空洞(20)のフロントゾーン(20c)内だけ、内側の空洞(20a)と外側の空洞(20b)とを流体連結した状態にし、二相流体が空洞(20)に入っていることを特徴とする、
エンジンナセル。 - 内側の空洞(20a)及び外側の空洞(20b)と分離部材(22)は、円周方向に連続的に伸びる、請求項1に記載のエンジンナセル。
- 内壁(12)と外壁(14)との間に配置された複数の分離要素(24)をさらに備え、内側の空洞(20a)と外側の空洞(20b)を、互いに直接連通していない対応する複数のセクタに分割し、且つ分離部材(22)を対応する複数の分離部材セクタに分割する、
請求項1に記載のエンジンナセル。
