Claims (5)
- 胴体と、
上面と、前記上面内の少なくとも1つの凹部と、前記少なくとも1つの凹部と流体連通する少なくとも1つの導管とを有する少なくとも1つの主翼と、
前記少なくとも1つの凹部内に配置されており、前記少なくとも1つの導管を介して圧縮空気を受け取るように構成されている少なくとも1つのエジェクタと
を備える航空機。 - 非常に積極的な空気力学的な幾何学的形状の翼形部のように近似的に形成された揚力発生表面と、例えば排気ガスの空気などの加圧流体の供給源を使用するエジェクタとを組み合わせた一般的な揚力及び推力増強装置であって、前記エジェクタは、それらの前記組み合せが、個別の翼形部形状の装置及びエジェクタを別々に使用した場合よりも多くの揚力及び推力を発生させるように、幾何学的及び機能的に揚力発生装置に大部分が一致するように形成される、一般的な揚力及び推力増強装置。
- 前記エジェクタの入口は、前記翼形部の上面に翼長に沿って最適に配置及び分散され、前記翼形部の前記上面の前縁上に、前記翼形部の上面に沿って流れ方向に形成される境界層吸い込みを可能にして、境界層剥離をなくし、従って増加した迎え角に対する失速を遅らせるか又はなくす、請求項2に記載の構造。
- 前記エジェクタの出口は、前記翼形部の上面に翼長に沿って最適に配置及び分散され、境界層がエネルギーを与えられ、前記翼形部の上面に沿って流れ方向に壁ジェットとして噴出されることを可能にして、前記翼形部の前記上面の揚力発生を制御する、請求項2に記載の構造。
- 加圧流体が、流体ネットワークにおいて前記翼形部を通してそのルートを介して前記エジェクタに供給され、前記流体ネットワークは、前記エジェクタの各々を個別に調整及び遮断することを可能にし、従って、推力だけでなく揚力も、必要なときに必要な場所に分配する、請求項2に記載のエジェクタ。
