First Certified Electric Self-Launch 18m Glider | AS33 Me

Hey Stefan, I just wanted to thank you so much for getting me into gliders. I finished a course in Colorado and am officially a certified pilot this last weekend. Wouldn't have even gotten into gliders if it weren't for your channel.

[@TheSoaringChannel]

@@Tomfriendly9000 in real life - don't ever forget that the motor may fail at the worst possible time, or not start at all, or worst yet, start, run, and then fail moments later. And when it fails, you can be assured its likelihood of stowing/retracting is 10%. So as you practice on MSFS keep this in mind. Maybe even do a few engine extended outlandings. The electric is far more reliable but I know personally of some failures with electric systems.

Cool! I landed on Bayreuth a few weeks ago (PH-588, BU Mini Nimbus) when I could not find any new thermals, and saw all these trailers and found out there was the German nationals going on.. Reluctantly they offered me a tow so I could fly back to my home base at Saal Kreuzberg, but I had to leave ASAP because in 30 minutes the first competition gliders were expected to come back... But the guys were very helpful and I was in the air again in 20 minutes or so, found a thermal and managed to get back home. But what a cool plane that is the AS33 Me, if I ever win the lottery, maybe this will be my next plane.. For now I enjoy my Mini Nimbus, still going strong and flying competition in club class (coming weekend Amstelglide from Soesterberg)

@@elkcircle7245 It's retractable but not steerable at the moment. Not sure if there will be an option available in the future?

[@elkcircle7245]

@@SteFly So, like Jonker they are favoring the retractable feature for competition, and avoiding the performance hit from external steering horns and cables such as in the ASH31. And maybe also avoiding excess electric energy usage / heat accumulation in the batteries and controller from taxiing onto the runway and back to the trailer. That makes sense, but it's going to limit the usefulness of having a self-launcher that has to be towed to the launch point, particularly at airports shared with power traffic. It will be interesting to see how the electric market evolves. Thanks again for your overview.

Hey, Stefan. Danke für das informative Video. Der elektrische Selbststarter für Segelflugzeuge ist viel zuverlässiger und umweltfreundlicher als jeder Verbrennungsmotor. Aber das Segelflugzeug verwendet eine gefährliche Hochspannung von 400 Volt. Da sich die Batterien in den Tragflächen befinden, erfordert der Auf- und Abbau nun mehr elektrische Sicherheitsmaßnahmen. Auch das Öffnen der elektrischen Propellerklappe bei Regen wirft zusätzliche Fragen auf. Wie wäre es mit einem neuen Hochspannungs-Sicherheitsvideo.

[@louisvanrijn3964]

Professor Loek Boermans told me, that a condition with say 20% - or more lift over the distance allows to use the so called Dolfin technique. This increases the overland speed dramaticly. Sparcely turning in thermals, flying with different speeds using slight zig zag. The "kurbel anteil" (amount of time turning) in a ka 6 is mostly 50% an this part has no overland speed.

[@theenthusiasticamateurpian9033]

The glide ratio is a given value at a given speed and given wing loading in calm air. If you add water you keep the same glide ratio but at a higher speed. That's the reason we put water in our wings.

Forgive me as I know nothing about sailplanes, but what is the device, shown at 6:48, that slides outboard & inboard on the wing leading edge? Is it some sort of weight?

[@ca_pilot]

Bug wiper. The bumps from the smashed bugs disrupts the laminar flow over the wing so cleaning it up help performance.

[@msierra3827]

You get dead bugs on your wings when you are flying and especialy a sailplane needs for the highest performens wings with out any imperfections. Thats why they install a bug wiper system which is what you see. It has one or multiple strings attached as it glides over the wing and removes a lot of dead Bugs so can fly further.

[@ernest795]

Only thing we need now is solar panels on the aircraft to recharge the batteries and you could go for days!

[@MusikCassette]

What would you think about putting solar cells on the win and reducing the batterie by 2/3? That way you would still have enough capacity for the self launch but the energy you can use during flight would come at a way lower weight panalty.

[@kevinfinke6927]

Sadly, there isn’t a cost effective production ready solar cell technology that could maintain the laminar flow on the upper surface. You would be wiping out ~40% of your laminar flow benefit on the wing. That’s a huge loss in glide performance. In strong conditions the weight isn’t an adverse effect, but rather a benefit in inter-thermal speeds.

[@SteFly]

Most likely to complex for the production and at the end you wouldn't safe a lot of weight.

[@MusikCassette]

@@kevinfinke6927 "Sadly, there isn’t a cost effective production ready solar cell technology that could maintain the laminar flow on the upper surface." All in all that should not be that expansive to build. But I can see, that it not being a thing (yet) could make it quite expansive to make it a thing. about the weight: if you are below your desired optimal weight, that gives room to something useful with the freed up mass. So I think weight cuts are allways useful for something. Also you probably need some of the cut weight for the solar cells themself.

[@MusikCassette]

@@SteFly perhaps there is something I do not see. but integrating flexible solar cell while forming a wing does not strike me as that complex. Also my hintch is, that you would not only save weight, but you would have way more Energy over the span of a flight than your Batterie would have stored. not to mention, if you have an outlanding and are out of energy, you would not be stranded. That strikes me as a worthwhile advantage.

[@scratchfisch6425]

@@MusikCassette If a launch to ~450 m uses 26% of the battery, I wouldn't want to reduce the battery capacity much, even with solar. Solar would also require a completely different wing compared to the non-electric / non-engined version of the glider, and would still be heavier than a combustion engine and enough fuel to beat its range. Engines like this are meant to get you to the nearest thermal, the last few kilometers to home, or to the nearest airport, not for long cross-country flights. Using the engine to take off after an outlanding is unrealistic. Firstly, taking off from a Field is (I think) illegal, most out landing fields aren't big or smooth enough for a safe takeoff anyway, and waiting for your empty batteries to recharge would always be slower than having somebody pick you up. If you landed on an airport, why not use their power to recharge and/or get a tow?

Never had much to do with gliders. What’s the black thing sliding up and down the wing?

[@Nico9472_]

That's a bug wiper. Especially during the summer, a lot of bugs tend to crash onto the leading edge of the wing, ruining the aerodynamic profile and causing extra drag. What bugwipers do is scrape the bugs off midair recovering a little bit of performance. Bug wipers are manually activated and can be found in the form of manual bug wipers where you have a little winch in the cockpit with the string attached, and you rotate a little lever to deploy and retract them, it's downside is that you're fighting against over 100km/h of air coming directly at the bug wipers, therefore, it takes time and some effort (you can see them on Stefan's ASG29), or in the form of electric bug wipers where the winch is connected to a switch and with that switch you can deploy and retract them, this system is more expensive but extremely easy to use, requires much less time and no effort (you can see them on Stefan's LS3). Most gliders can be retrofitted with the system, but, not being built with bug wipers in mind, they will be sticking out causing extra drag and are therefore removed when there aren't a lot of bugs and aren't needed, while on the most modern gliders (such as the one Stefan is flying in this video) the manufacturers build the gliders with bug wipers in mind and they fit them as part of the fuselage itself, therefore they don't stick out when not deployed and don't cause extra drag, meaning there isn't any reason why to remove them.

[@YouriCarma]

Being a bit critical I don't understand why they didn't make the prop blades pitch adjustable, one could even use that as an adjustable air break so to speak. Now when the prop comes out it immediately produces a lot of drag. One could also use the prop as an active air break I guess, which turns the prop direction in the opposite way. Not sure if they've build that in? Don't find it a very subtle design to be honest. Probably very practical but lacks in smart design which could improve the whole concept in my opinion.

You would not fly a machine like this for the purpose of travelling under power. The power unit is used to make it easier to spend time gliding. In competition, if you start the engine after starting the competition task the flight is treated as ending at that point. It doesn't have the range or luggage capacity for any transport purpose.

All these gliders are a compromise, the same as combustion engine slef-launchers. AS33 Me is relatively heavy but has a good range and tested propulsion system. JS3 RES is more flexible with the two batteries and slightly less heavy, but has only about 2/3 of the range. MTOW is also limited with batteries.
