流体流動制御機構を流体流動の線形化のために提供する。 該機構は、複数のプロペラ素子をその上に回動可能に支持する円筒状の外側バッフルを有するフレームを含む。 各プロペラ素子は、プロペラ素子が回動する各掃拭域を定義し、該掃拭域は、隣接するプロペラ素子の掃拭域と重複する。 外側バッフルは、各プロペラ素子の集合的掃拭域の外周に外接する。 該プロペラ素子は同方向に回動して、隣接するプロペラ素子の屈曲流動のが実質的に互いに相殺され、前記機構を通過する流体流動は線形化されるのである。 羽根の非掃拭域内に追加されるバッフルと充填材とを、機構の特定用途のために設けてもよい。 様々な適用においては、接線流動の屈曲力の統合によって、ベクトル流動の線形力が形成され、そして、プロペラ回動平面上の屈曲力ポテンシャルの統合によって、効率流動系が形成され、放出流動と導入流動とを遮断し、これにより、動的流動の直近の流体は、乱されていない静的状態に保たれる。 これによって、流体推進組み立てにあたって、領域の静止帯域の外部効用マントルに備えることが可能となるのである。
