Abstract
【解決手段】エアフォイル40の製造システムは、レーザービーム74と、レーザービーム74を取り巻く第1の流体カラム76とを有し、エアフォイル40に向かう閉じ込められたレーザービーム74を生成する。エアフォイル40の内側を流れるガス80が、エアフォイル40の内側の第1の流体カラム76を分断する。エアフォイル50の製造方法は、第1の流体カラム76の内側でレーザービーム74を閉じ込めて、閉じ込められたレーザービーム74を生成し、この閉じ込められたレーザービーム74をエアフォイル40の表面に向けることを含む。この方法は、更に、閉じ込められたレーザービーム74を用いてエアフォイル40の表面に穴を形成することと、エアフォイル40の内側にガス80を流すことと、エアフォイルの内側を流れるガス80を用いて第1の流体カラム76を分断することを含む。
