Abstract: Axial flow devices using rigid spiral band profiled blade catenaries attached variably along and around an axially elongated profiled hub, of axially oriented profile section sequences 75 mapped relative to truncated cones-of-generation. Upon rotation and lubricity-masked progression through axial planes-of-shear, this time-domain sequence travels in 2-dimensional axial-datum-plane-relative path-excursions and ejects frictional adhesions via anguillar reverse vortex street thrust due to an after-body accelerating wave shape-sequence 48. This guides bound vortex pressures at linear path-velocity substantially parallel to the collective plane-of-shear, conferring higher differential pressures through path-vector-addition, improved force-vector orientation, extended laminar flows, lower form drag and tip vorticity. As a wind turbine, path-vectors are added to inflow, ducting an increased mass flow inward for increased power extraction per diameter.

Abstract: Devices benefiting the deceleration or acceleration of fluids by augmenting rotor-differential-pressures using rotor-phase-locked shear-plane pressure waves, and influencing system hysteresis and fluid-vector-shear through pulsed feedback, and resonance. These oscillations being generated by rotors embodying means 48 to engender waveforms conferring efficiencies through optimized vectors, and extended laminar boundary layers.
