How Slow will it Go? Turbulator Tape Testing the E-flite DRACO

Ойын-сауық

Feeling the desire to tinker, I was curious if applying some aerodynamic treatments to the outboard, non-slatted wing sections on the DRACO wing might get it to fly a touch slower. While it flies plenty slow, my hypothesis was that there could be laminar separation out at the wing tips causing it to wallow at really slow speeds. So, I added some zig-zag turbulator tape to intentionally trip the flow to turbulent at the tips as that would keep the flow attached longer. I think it did help get it a touch slower and get the AoA a little higher as well, but ultimately you can only get so close to 0 airspeed. You can be the judge, it was a fun experiment to try. :) #slowflight #DRACO #TheRCGeek

    Good work Chris, I too looked at the slat fence line compared to the outboard washout and the standard boundary layer separation is definitely going to be aggressive at the tips. This addition would definitely help. I’m still trying to sort out the adverse yaw in the turns using better stick coordination rather than being lazy with additional mixing.

    good info. Always want to stall full ahead across the full span without a wing drop to either side....that is bad because that's how you enter spin territory. At least if you stall straight ahead you have some chance to power/fly out of it. Dropping a wing, not so much (as I think a lot of guys who have the Draco have found out)

  • @Thercgeek

    Since the slat is there, that already turbulates the flow through the gap. So, adding the zig zag tape through that region won’t provide much benefit.
