@@thinkflight i was under the impression you're doing all this just for fun. if a little bit of video like this puts food on the table in CA then i wonder what it could do for me living in some cheap place.

I once wrote an aspect ratio design analysis program for RC sailplanes The program was based on Martin Simmons book on model aircraft aerodynamics and ran in basic 7 on a commodore 128D, gives you an idea of the vintage. What I found was that for a 100 inch span and fairly light wing loadings achievable in a balsa & spruce construction, sink rate was generally minimised at an aspect ratio between 10 - 13. Just prior to that, this had in practice work out pretty well for a slow high lift floater flying calm & relatively inactive conditions. The model was a stretched and tapered wing version of a Soar Birdy 86" span with which I got 2nd place in my LSF national soaring comp Jerilderie Australia with just such a model. However, higher aspect ratios resulted in increasingly higher wing loadings and air speeds on an increasingly flatter glide slope. The improved glide slope did not out weight the adverse effect on sink rate due to higher airspeed. However, it did improve the models range and therefore ability to search for lift over a larger area & especially it's ability to do so in stronger wind conditions. So basically, it became a gambling game. I have put quite a lot of effort into optimising height from a bungee launch. I could pretty much get more launch height than than anyone else Because of the high camber wing & more rearward tow hook position, I had to hold a little down trim at the start of the tow to prevent the model doing a premature auto release while climbing vertically. It was astounding how much more height I was getting & there was winging to the committee, but everything was comp compliant. The only difference was that I had put the time and effort into trimming & preparing the equipment to get then best performance out of it that I could. Anyway, I had 2 models at the time. 100" span using a scaled down Bird Of Time wing section. This is a much less cambered and thinner higher aspect ratio wing than the other model. Bothe models had similar wing loadings but this higher aspect ratio model was notably much faster had had a much flatter glide. It could cover a lot more ground searching for lift. However, that particular competition had cool weather and calm conditions & the floated won out over it by quite a lot. My opinion though remains that it would have gone the other way if conditions had been windier with more active lift. For these 2 modes, it would normally be the case that the broader wing should have the less cambered section and the higher aspect wing should be the more cambered section, but this was early days for me, before I read Martins book. It's just that having studied the aerodynamics and then written the program removed the mystery & with it the interest, so I didn't continue to pursue sailplane design. I had also designed a few models with too short a moment arm which unfortunately led to overloaded (stalled) tailplane during F3B speed runs & diving into the deck. Normally the moment arm would be between AC wing and AC tailplane would be 4 times the mean wing chord for most model sail planes. In order to achieve balance with less nose weight, I went for 3 chords, which was fine for normal soaring flight, not fine at speed though. I think the 3.5 chords might have been adequate though. As it was, I would start a ballast loaded speed run and at some point the nose would continue to drop despite up elevator control. After that I bought a Sirus (2Ch) that someone else built, it clapped it's wings slope soaring over sand dunes. Repaired it, strengthened the wings with a new I beam main spar, redesigned the tips & rebuilt the rudder & tailplane with a geodetic structure. Installed a completely hidden in a closed loop rudder hidden cable system as the fin is suitable thick. The model died one day when another pilot switched on their TX on an adjacent channel. I had had many thermal flights well over an hour with that model, only landing to rest my neck. That model had a fairly high aspect ratio high camber wing. It could cover a lot of ground sniffing out lift, reasonably good upwind speed, not exceptional. It could would loose out against a floater if no lift was found, but most time I'd find lift. It had no provision for ballast though. I had it disappearing into clout a few times. The fully flying tailplane had differential control throw. I could half loop over to inverted to drop out of the cloud base lift & bring it back home. Rudder roll it to upright flight again for landing. All in all it was a rather nice model to fly. see below.

@@thinkflight Ta, Then you may also be interested: I did a statistical analyse aimed to best approximate the "ideal" elliptical span loading with a simple double taper wing. It turns out that the standard deviation on the span loading's departure from elliptical is minimised when the inner panel is a constant chord for 40% of the semi span & the outer panel tapers to 60% of the root chord at the tip. I never built it though. It would be slightly unusual in that the centre panel is shorter than that of most double taper wings & the tip chord somewhat less as well. Most tip chords go to about 70%, maybe even 66,6% (2/3) of the root. Many are scared of tip stall & cautious of making the tip chord too short for that reason, but combining a small increase in camber with a little washout, gives the tip the same AOA and higher Cl max before stall (safe from tip stall), without changing its zero lift reference relative to the rest of the wing. Anyway, it "should" make for a slightly more efficient wing, not that you'd notice really, maybe a few seconds extra duration in dead air. On the other hand, you'd get a lot more benefit from adopting Prandtl's bell shaped lift distribution at the same root bending moment as that extends the span very significantly reducing induced drag. The maths looks a bit tricky to me though. There is a fair bit on the net about this these days and in English translation no less!

Amazing video as always, also loved the YF-23 at the beginning. Just a correction on a tecnical note: multiple time you said that high AR (aspect ratio) is for grater efficiency at lower speed. This is not entirely correct, in fact the AR determines mainly the max aerodynamic efficiency (lift to drag ratio), while the speed where the peak efficiency is achieved is determined by the wing loading (aircraft weight over wing aera). Also sometimes is better to think about not the speed of max efficiency, but rather the dynamic pressure of max efficiency (q = 1/2* TAS^2 *rho); in this way you take out of the equation flight altitude (the higher you fly the lower the air density so the speed of max eff. increases). In my opinion the best way to undesteand intuitively those concept is by "playing" with the equation; I use Desmos for plotting the graps (you can set up sliders to visualize what happens when you change various parameter); than Matlab for more complex optimization.

Great breakdown, I think its worth mentioning that swept wings, and the delta wing of your foam model, are generally designed with trans and super sonic effects in mind. Swept wings can lower the effective mach number and delay the formation of transsonic effects. Delta wings keep the wings out of the shock formed by the nose at supersonic speeds and generate lift differently at lower speeds, hence the larger angle of attack

Great Collab video, well done fellas!

You can see the same effect in birds: the long slender wings of an albatross, vs the wings of a peregrine falcon. Another important part of the equation is maneuverability. Multiple factors are at play, but one important aspect is the spatial relation between the center of mass and the center of the lift.

Long thin wings produce less drag, but are much more unforgivable in terms of actually flying them, prone to ip stalls, prone to sudden loss of lift due to the narrow chord, harder to build... There is a lot of pros and cons to a high aspect ratio wing..

That plane with the skinny wing would make a good FPV cruiser glider if fitted with a bigger battery and long range antennas, also if fitting with a 360 degree gimbal for FPV camera with head track on the nose would basically give you the best flight experience but due to FAA regulation would make such flight impossible without the flight clearance waiver. Still would make a good slope or flat land e-glider, now would be nice if plans are available to build one.

Its interesting how this can change based on scale...from my understanding, once you start getting small enough, leading edge drag starts to become higher than skin drag, so shorter wings start to become more efficient again. ...at least, thats what I remember...yeah dont quote me on that lol

@thinkflight

Жыл бұрын

Its more of a reynolds number thing, when the reynolds numbers get really low things become inefficient again so at really small scales, keeping the chord as big as possible becomes your best bet to keep the reynolds numbers as high as possible rather than going for aspect ratio.

Please share the design for 3d printing or make a build video. Does it really fly for 3 hours with 2s battery? please elaborate it

@0:44 y'all protest to fiercely I think. Confident people don't need to spend any amount of time diminishing others and virtue signalling about their manly diet.

Long skinny wings (high aspect ratio) have lower drag than fat wings (low aspect ratio) also at low aspect wings have greater resistance to stalling, the high aspect can stall unexpectedly. See gliders and jet fighters.

Would you consider using this platform to test using mid wing mounted motors to counter act the mid wing vortex you noticed in your wing tip mounted motor? I've always wondered if that's the key to efficiency in flying wings. It looks like you either had the same or a similar idea with the vertical stabilizer placement. Just a thought, I'd be very interested in the result. Love your videos! Keep it up!!

I'm loving the content man! Neat to have the performance of both type of wings demonstrated. Can't wait to see more. Keep the great videos coming!

Great in-flight footage!

if the wing area is kept contant, there is a point after which an even higher ar will decrease performance due to the decrease in re number, meaning the airfoils stop working properly so the saying "higher ar is always better" is technically not correct i once did a number of simulations testing this, on a rectangular planform wing with a wing area of 0.1m² (10cm chord at 1m span) i varied the ar and aoa and compared performance with L/D can't remember the airfoil rn up until an Ar of 25.6 (span 1.6m, chord 6.25cm) L/D kept increasing to a maximum value of 18.5 at higher Ar's L/D dropped again

I'd love to see your process for designing when using a computer

You just described the most commonly described differences between low and high aspect ratio wings. But, you should also note the reasons why some people have suggested replacing the stubby wings of the F-16 with a delta wing, and why relatively high aspect swept wings might be preferred in some cases vs a delta wing that "fills in" all that space behind the leading edge of the narrow wing. In other words, there's a lot more to the wing form than just whether the wing is high or low aspect ratio.

Low and slow. Beautiful 😊

Here's a question: At what *actual* velocities does the crossover happen between induced and parasitic drag? Is this different for our small RC aircraft? How does airfoil shape (or other important factors) effect this? What other important factors contribute? Obviously, there are (I'm sure) decades of math to figure this out based on as many variables as there are stars in the milky way galaxy. I would *LOVE* if you could do an in-depth analysis of choosing a specific aspect ratio and/or airfoil shape. How did you choose the specific wing profile for your high efficiency wing in this video?

How does the slender wing thermal? I have always wanted to try that with this type of wing.

At the speeds reachable by our RC airplanes where compressability effects are not a concern a high aspect ratio wing of the same wing area will consistently outperform a low aspect ratio wing even at high speed. The low aspect ratio wing will not have a smaller forward profile area because the thickness of the wing is proportional to the chord length. There's a reason the speed records for RC planes are held by high aspect ratio sailplanes dynamic soaring. When a lower aspect ratio wing makes sense it's because of structural limits, span limits, stall characteristics, and manufacturability, not because you want to fly faster.

Long skinny wings are definitely good for efficiency, but I've noticed issues with very light planes. When the wing span is large in relation to the airplane weight, the reynolds number is fairly low. Below about 50,000 most airfoil designs have lots of issues, so the L/D is very low. In this case having the airplane fly faster at a lower AoA is better due to the increased reynolds number and therefore increased L/D.

It's all about flight envelope. Skinny wings have no air brakes, so they go fast on little power but fall out of the sky at low speed. Wider, thicker airfoils have a wider flight envelope, sacrificing a little top speed but needing more power. Thick and wide airfoils are much more fun to fly.
