  • Strong Santa Ana conditions on Jan 19 2021 provided enough wind for Spencer Lisenby to bring the dynamic soaring speed record back to its birthplace of Parker Mountain, CA. Wind gusted to 65mph and temps were 45-50F. This flight beat the previous record set in 2018 at Bird Spring Pass by only 3mph. Filmed with a Gopro on my head while flying. Best viewed on a large screen with high resolution. Max acceleration estimated around 90-100G.

    Model is the Transonic DP:

    and NO, the video is not fake or sped up...
    548mph = 882kph

      it's only minor corrections every loop; it's not entering and exiting multiple maneuvers, just the loop is established and keeps getting boosted. I noticed sometimes the loop ended up higher. the amount of control deflection to work safely at those speeds must be miniscule

      Yeah seing how you can accelerate to 548 miles an hour using windspeeds that go up to 65mph, makes you wonder what you can do with solarwind speeds between 450 and 700 miles equator/poles not per hour but per second. But what i wonder most is what G forces you then can expect? Wouldn't that be beyond anything materials can handle? I mean if it's having the same speed difference that craft could go to 5000-6000 mps! Around 2% the speed of light! Still would take around 220 years to reach Proxima Centauri though. Sure you can use the same trick at the edge of the solar wind where interstellar winds take over but with that speed? Seems like impossible to me but i ain't a scientist.

      Full scale pilot here that's flown RC a few times (definitely not doing this) with the same question.
      My speculation is that you don't have a closed-loop mindset (as in "closed-loop controller" from engineering, not the looping maneuver... wish there was another word!) like controlling any typical maneuver, where you're watching deviations and correcting them on the fly. It's too fast for that. But rather, after enough practice you have the muscle memory with your thumbs of how to fly one of those circles, and if you notice one go a little bit wrong, you adjust for the next time around. And you get in a rhythm/groove with their cyclical nature, making small adjustments each next one.
      I'd love to get a real answer here from those who fly DS.

    • @sll914
      @sll914  3 роки тому +29

      @@FlyNAA I think it's like you say, muscle memory developed thru lots of practice. After a while you learn to recognize deviations from the desired path earlier and you can fix them immediately. Beginner DSers usually have one point in the circuit (top turn) where they make corrections and over time you add more and more points in the circuit where you recognize and correct issues. The ultimate goal is to develop so many points along the circuit that your corrections become constant and small.

      In the hobbyist segment, such is faster than any RC aircraft with a motor. Even those with jets or small booster rockets are still slower. If you want faster remote piloted aircraft you'd have to look to something government owned, which then tends to be military aircraft or drones.

      Problem is more that you have to see and control it. Flying circles needs rudder deflection and rudder deflection creates drag. So hard to get supersonic that way.
      Put stub wings onto a rocket will easily get you supersonic, but it will more or less fly in a straight line and might be out of sight soon. There are numerous supersonic hobby rockets out there.

      glider takes advantage of shear over the top of the peak. ever seen time lapse video of a cloud or fog near a mountain top? the fast moving air blows over the top and there is a cushion of higher pressure still air where the fog curls under its self on the leward side of the peak. the glider moves back and forth across this shear boundry and picks up speed in the fast moving air then turns into the still air to climb back to the peak to turn back into the fast air. Its called dynamic soaring.
