Distinguishing some families of AWES regarding autorotating rotors
- This topic regards distinguishing several families of AWES that use autorotation of airfoil blades for aloft generation or groundgen This note neglects some other cases not mentioned. And the note uses rotor in singular with awareness that the unit may be multiplied so the systems use multiple rotors. Filling out the list is invited. The following list order is without prejudice to time or merit.F1: The rotor is lifted into the upper winds by a substantially remotely tethered wing set. Say an early kite-motor by Dave Santos that has been demonstrated and imaged recently in the forum.F2: The rotor is set tightly within a kited wing where the non-rotor global wing is doing the mass lifting and the rotor is set dedicated for generation of electricity and not for mass lifting during generation. Say, Pierre's flygen or Dan Tracy's flygen or Makani's flygen or Altaeros LTA flygen.F3: Tailed turbines. A main kited wing featured a tail system that involves rotors that generate electricity or torque. Depending on the tail-system design, such rotors would be giving some negative kiting during spin and generator or neutral kiting or, if specially arranged ... some positive kiting.F4: Double-duty and perhaps triple-duty rotored AWES, say the rotorcraft of Bryan Williams Roberts that feed into Sky Windpower's explorations. The rotor is used for powered helicopter flight, for unpowered gliding flight, and for inclined unpowered autorotation gyrokiting during generation where the rotor stays double-duty working to lift system mass and give some mined rotation to generate electricity aloft.F5: Rotor kite, gyrokite AWES, say as Grant Calverley is exploring. The option of Yo-yo groundgen using gyrokiting is open to them. They are in stealth mode; they might report on other options for their team, say flygen, instead of the Yo-yo groundgen. A soft-wing direction is the Yo-Yo "Roto-Kite" given into public domain for a groundgen.F6: Torque shafts (of various designs) driven by various arrangements of rotors. We have DougS deeply into this family. Various mass lift solutions are involved in variants. Groundgen is emphasized.Missing families along are welcome to be stated and discussed.
I hear what you are saying, DougS ! Usefulness is a neat arena. Use language to move one's project forward; one need not use the words and concepts that are not helping one's project. Be prudent for one's life and project.
For me, yet, I am finding neat usefulness for the findings about kite essence as such plays in different realms. I've advanced from your seeings; thanks for the play. A mastery over the essence just may help one move in the most practical realms also. Yet, a worker may focus on one niche mechanical project and not have much need for mastering kite essence in other realms; he or she may have enough text to complete a certain project.
It took only a second to click-share a few years ago that a strand of string in the air or in water will have its times as a true kite system and WEC and thus AWES; but such awareness may not much help Magenn MARS system project. However, there well may be some niche scientific research that could benefit from appreciating the kiting going on in a strand of string out in the air or water. The strand of string in a real dynamic fluid goes through many kinds of motions; some of the actions fly the end portions deferentially and sets up tension in the mid sections of the strand; compression and tension is occurring; segments react with the whole in various ways. Have the string with ribbon flat shape and get even more actions.
