• External electric quick-detachable sustainable device for a glider

    From Evgeny Prudkov@21:1/5 to All on Sat Aug 6 06:03:42 2022
    Hi, I ask you to evaluate the sustainable device for the glider. Right now it is installed on my LS1d. Consists of the body, the battery, the motor and the folding propeller. There is no need to rebuild the airframe, it is enough to reinforce the body
    from the inside with a fiberglass sticker and drill 6 holes in the skin. Installed and removed in half an hour. If necessary, the pilot presses a button, the tail of the thin plastic fairing falls off, the motor turns on and you can fly horizontally for
    about half an hour. The L/D of the glider, of course, falls, but not more than 7%. But you can return from a distance of 50 km. Well, or find a thermal, I hope. The photos you can see on https://www.facebook.com/groups/glidingandsoaring/#_=_
    Would you buy that ?

    I think it would be more attractive if it did not have the rear fairing; instead, a
    rearward folding propeller would be exposed, and the fairing would narrow down to the
    propeller hub. No fairing to drop, and the motor could be used at any time, as needed
    during a flight.

    What is the weight and expected cost?

    What price? What delivery time? What kind of battery? What kind of charger? How long to charge?

    Maybe put the battery inside, leaving just the motor and folding prop exposed? What’s its maximum thrust?
    I believe a standard class sailplane has about 20# of drag at best L/D…….? Interesting idea,

    "The fairing falls off," so it has to be replaced after every use (and the old one litters the countryside)?

    7% loss would mean you will need it on most flights (at least the ones I do). 50km should be derated by half when one considers headwinds and clearing obstacles. This means 25km, or 16mi - I am on a final glide 16mi out.

    Sorry, but I am not interested.

    It's totally unsuitable for your ASH31Mi, and seems intended for smaller, lighter gliders.
    Perhaps you are thinking of getting a 13 to 15 meter glider in addition to the 31?

    Obviously, I don't need it - this is my evaluation in the hypothetical situation that I was flying a gravity glider. If I were, I would not want to sacrifice 7% performance for such a limited range plus all of the aggravation of dealing with batteries (
    which he doesn't explain where they will be stored, how they will be charged, or their type).

    From the FB discussion, the battery is inside the pod. 22 kg total
    weight. And the new improved model doesn't drop the fairings, they're
    tied to a rope that's glued to the middle of the fuselage. I assume
    they nick up the finish as they're dangling in the breeze.

    Gotta admit, this thing does make the Jeta look a little more attractive :-)

    Jetta's had the big car emissions scandal, I was thinking of the glider scandal.

    What happened to Mr. GoofyGlider, he was desperate to get his hands on a
    Jeta?. I pointed him to two for sale, which happened to be (and still
    is) the entire world supply of the type.

    Meanwhile, article number 0002 still languishes on W&W. Somebody needs
    to give this puppy a home. Eric? Raul? Ramy? GoofyGLider?

    Good question. It's looking for its fourth private owner, with zero
    hours on the airframe. Don't see that everyday.

    The bigger question is why the dealer doesn't grab it for himself? I've
    heard he has one on order, yet he keeps showing up at contests flying an
    LS-8. Why not go with the latest and greatest? In the electronics
    industry, that's what we used to call "eating your own dogfood".

    Hi, I ask you to evaluate the sustainable device for the glider. Right now it is installed on my LS1d. Consists of the body, the battery, the motor and the folding propeller. There is no need to rebuild the airframe, it is enough to reinforce the body
    from the inside with a fiberglass sticker and drill 6 holes in the skin. Installed and removed in half an hour. If necessary, the pilot presses a button, the tail of the thin plastic fairing falls off, the motor turns on and you can fly horizontally for
    about half an hour. The L/D of the glider, of course, falls, but not more than 7%. But you can return from a distance of 50 km. Well, or find a thermal, I hope. The photos you can see on https://www.facebook.com/groups/glidingandsoaring/#_=_
    Would you buy that ?

    Is the 7% reduction in L/D before or after the tail cone is dropped? And, I assume, the 7%
    is at best L/D speeds and would be significantly higher at normal interthermal cruising
    speeds.

    I agree. This device is a "proof of concept" in it's current state of development, and not
    even a production prototype, much less something being offered for sale. I suggest pilots
    interested in the concept of an easily added sustainer system tell the developer what
    features and price would make it attractive to you.

    Fiberglass parts dangling from a rope are likely to get dinged up pretty well upon landing as they get dragged down the runway. The concept is interesting, but I'd be surprised if very many people would take 7% off their L/D in exchange for a self-
    retrieve option. Depending on the aircraft and the price, an FES conversion might make more sense. Or, maybe a more streamlined design where the battery pack goes inside the fuselage. It's not as modular, but I'm not sure what the benefit of making it
    removable is...well, except for the drag on performance, but that would get resolved with less of the system hanging out in the breeze.

    Reminds me of the TOP (Take Off Power) kit which was sold for the ASW20 way back when:

    Good question. It's looking for its fourth private owner, with zero

    The bigger question is why the dealer doesn't grab it for himself? I've heard he has one on order, yet he keeps showing up at contests flying an LS-8. Why not go with the latest and greatest? In the electronics
    industry, that's what we used to call "eating your own dogfood".

    Gotta admit, this thing does make the Jeta look a little more
    attractive :-)

    That's what I want: glider parts flapping about in the airstream,
    banging up my glider! I doubt that it helps the L/D, either. Just
    when I thought this concept couldn't get worse...

    If this is what it takes to make the Jetta look better the Jetta is
    in REAL TROUBLE!

    Tom

    Jetta's had the big car emissions scandal, I was thinking of the
    glider scandal.

    What happened to Mr. GoofyGlider, he was desperate to get his hands on
    a Jeta?. I pointed him to two for sale, which happened to be (and
    still is) the entire world supply of the type.

    Meanwhile, article number 0002 still languishes on W&W. Somebody needs
    to give this puppy a home. Eric? Raul? Ramy? GoofyGLider?

    https://wingsandwheels.com/classifieds/motorgliders/gp-gliders-gp15-jeta-2.html


    How could a glider that was NEVER flown be airworthy? For my 31 Mi to have a valid U.S. airworthiness certificate I had to fly it for 5 hours and 5 flights at Williams.

    I agree. This device is a "proof of concept" in it's current state of development, and not
    even a production prototype, much less something being offered for sale. I suggest pilots
    interested in the concept of an easily added sustainer system tell the developer what
    features and price would make it attractive to you.

    Towplanes have 200' of "dangling parts" [the rope] for Tarzan to swing on, and you fuss
    about a small plastic cone on a couple feet of string? Our club was fortunate we only had
    a couple close calls with ropes on towplanes, but we did spend many hours bonding,
    searching for tow ropes that didn't come back on the end of the towplane 8^)

    Eric, thanks for the reply about that beautiful, Purist launching , rope dangling, Pawnee tow plane. We really don't have a problem with the rope, it is a beautiful sight to behold as the rope attaches to the glider for launch, even you motorglider guys
    and gals use the rope, especially when those gas smelling, non reliable motorglider engines fail. Old Bob, The Purist

    Hi, I ask you to evaluate the sustainable device for the glider. Right now it is installed on my LS1d. Consists of the body, the battery, the motor and the folding propeller. There is no need to rebuild the airframe, it is enough to reinforce the body
    from the inside with a fiberglass sticker and drill 6 holes in the skin. Installed and removed in half an hour. If necessary, the pilot presses a button, the tail of the thin plastic fairing falls off, the motor turns on and you can fly horizontally for
    about half an hour. The L/D of the glider, of course, falls, but not more than 7%. But you can return from a distance of 50 km. Well, or find a thermal, I hope. The photos you can see on https://www.facebook.com/groups/glidingandsoaring/#_=_
    Would you buy that ?

    I have an LS1-d and have been known to fly it once in a while - when the weather doesn't SUCK on weekends - and I'm not in favor of adding a "feature" that decreases the glide performance of ANY percentage.

    I love towplanes! That's how a lot of my soaring buddies and other glider pilots take to the
    skies. But the rope...it can give, but it can also take. A major feature of self-launchers is
    the greatly improved safety for tow pilots.
