Description
Claims (6)
- ノズルの周囲に沿って分散されたシェブロン(40)で形成された、いわゆるシェブロンタイプの後縁を備えた下流側部分を少なくとも備える、特に航空機推進のための排気ノズルにして、シェブロンの各々が、自由端部が2つの収束する下流側方向に配向され、前記後縁を画定する状態で、上流側の横断面(43)と下流側の横断面の間を下流側に延び、シェブロンが、ノズルによって発せられたジェットの境界部において渦を発生させる、排気ノズルであって、補助ガスジェット(A1)を注入する手段(50)を含み、前記補助ガスジェットが、シェブロンの自由縁の上流側で前記渦を発生させるためにシェブロンの前記上流側平面(43)の上流側に排出するようにしてシェブロンの前記自由端部(41、42)の上流側に注入されることを特徴とする、排気ノズル。
- シェブロン(40)が、軸方向の対称平面を有し、補助ガスジェット注入手段が、前記対称平面の両側に補助ジェットを注入するように配設される、請求項1に記載のノズル。
- 補助ガスジェット注入手段が、補助ジェットをノズルの軸の方向において、前記軸に対して10°から50°の間の角度で注入するように配設される、請求項1または2に記載のノズル。
- 接線成分を有する補助ジェットを注入するように配設された補助ガスジェット注入手段を備える、請求項1から3のいずれか一項に記載のノズル。
- シェブロンが、ほぼ三角形または台形の形状である、請求項1から4のいずれか一項に記載のノズル。
- 請求項1から5のいずれか一項に記載の排気ノズルを少なくとも1つ備える、複流ターボジェット。
