@TheJustinJ Год назад

If it looks good motto dose not apply in aviation. That was how all of the aircraft of the 1920s-30s were built and they are all unanimously deathtraps that are slow and sluggish and overall terrible. If its designed well, and built well, and tested well, and modified rationally, it will fly good.

@nntflow7058 Год назад

Is it more beneficial compared to the standard T-tail?

@nntflow7058 7 месяцев назад

It looks good, but realistically speaking. T-tail would be more realistic.

@nntflow7058 2 месяца назад

I would say, while it looks good, it's probably not gonna be suitable for these type of aircraft. T-Tail seems to be the perfect solution for such wing design.

@ludovicbon5903 Год назад

There is an interesting motorized sailplane with braced wings made in France in 1967, the Chapeaux-Durand CXD-18 . The struts are profiled and mobile to also serve as ailerons, flaps and airbrakes . She's displayed at the air museum of Angers-Marcé in France .

Awesome achievements! Flight is so fascinating. I was marveling, just yesterday, while watching a foursome of Canada geese amble around our neighborhood. I was thinking how marvelous are their wings, which fold up to exactly the right dimensions, perfectly conforming to their bodies, and providing insulation. Then, if spooked, the wings extend instantly, and explosively launch the large-bodied birds into the air... a miracle of nature's design.

Put strips of 30 grit sand paper on the upper leading edge of those small drop ships. The small bumps act as turbulators and energize the boundary layer keeping flow attached and vastly improving flying characteristics.

@TheDorazio Год назад

Thinking you might want to try spring-loaded wing extensions on the micro drone with a pull-pin trigger when it drops out of the bay. The flight dynamics with the kind of profile and size you have now to fit in the bay are probably always going to suck.

@nonsequitor Год назад

Amazing video as always. Thank you. One thing tho: what's the difference between strut and truss braced? You kinda skimmed over that part - it looked like truss means strut plus extra support (which is what a truss is) but your design has no trusses 🤷‍♂️🙏

@bradycope2332 Год назад

Yes! I was worried I missed something. Would love to understand this concept.

@robertheinrich2994 Год назад

fun fact: you connected the truss brace to the engine nacelle to reduce drag at the joint. if somebody at boeing comes up with that idea now and tries to get a patent for it: thanks, due to this video, it's prior art. but I guess, there were already planes with such a configuration so that doesn't really matter.

@noeatnosleep Год назад

Thank you for the extra footage :)

@Hobz79 Год назад

Awesome plane! Really took it to the next level by also giving a small drone to drop, which I look forward to seeing more of. Not a new concept, but I wonder how well the truss being swept back so far could double as a replacement for the v-tail by putting control surfaces on it. Would be less stable being so close to the wing, but that's what computers are for and might be worth the loss in drag :)

@thinkflight Год назад

I think that is an awesome idea!

@roboman2444 Год назад

A bright LED turning on inside the bay a few seconds before opening the doors could help with the camera's white balance being blown-out by the sudden change in brightness.

Build same weight similer size airplane with regular configuration with 4 channel control Use FDR for both input and attitude recording (record both input and attitude simultaniously, may be tap signal from potentiometer of servos) Conduct data gathering on headon wind and zero throttle condition and min throttle condition Observe sink rate and glide slope,

So what's the difference between a strut and a truss? Is it a compression/tension thing, or???

No it is ambiguous, strut harkens back to timber. I'd argue it is neither as it is a lifting plane, so a support wing or something might make more sense.

My Dad has built small balsa gliders since he was a kid and one thing he is adamant on is that you can scale down the airplane, but you can't scale down the air.

Put your glass fabric on at 45deg (draped on the bias) it'll allow both warp and weft fibers to contribute to stiffness, and you'll be able to get the fabric to lay down over the airfoil a lot easier. piece of unidirectional tape in a shallow groove under cloth for spar cap on top and bottom. Love this aircraft!!!

@burbman60 Год назад

your video makes me want to give up all my hobbies and go back to aviation and composites.

@TrogdorBurnin8or Год назад

There are other side benefits to this sort of approach with model aviation. A significant issue for scaling up RC to larger sizes for most people, and sailplanes to higher aspects ratios in particular, is "How do I fit it in the car". Mostly they resolve this with short reinforced spars connected by insertable carbon fiber struts, heavy features which defeat some of the goals of the light sailplane approach. This design has built-in hardpoints for wing attachment and mass-efficiently minimizes wing flex.

@techstuff6829 Год назад

I'm curious why you chose to use a push/pull configuration for the props rather than single larger props. Is it to allow the use of smaller props, or is there some other benefit?

@masterpye69 Год назад

Hi, I was amazed by your model! In 2014 I designed an almost identical aircraft with 80+ students of Cranfield University, UK, in part of our Group Design Project of the MSc Aerospace Vehicle Design. We named it "AT-13 Albatross ", you can find a rendered video of the project if you type this: AT-13 Albatross - MSc Aerospace Vehicle Design (AVD - Cranfield University) I was responsible of the Flaps design and part of the Physical model team (but not flying RC model). I hope we will see such low-emission civil aircraft in a close future!

@chrisoakey9841 Год назад

I suggested this type about 2 years ago. But if you split the wing you can get rid of the tail. By putting the front wing sweeping backard from above to meet a forward swept wing from under near the rear. If they meet at a winglet you get lift advantages as well as strength and added flap low speed lift. As the lift is further back,and the wings sweep back, it should be possible to create supersonic planes that glide. I would love to see one like my idea trialed

@thinkflight Год назад

Somebody on discord was talking about the same thing, I least I think you guys are describing the same idea. I think its an amazing idea.

@chrisoakey9841 Год назад

@@thinkflight it derived for me from the delta wing drawback for climb and maneuvering, and the slow speed lift advantages of flaps with gaps, or cascading multiple wings. the other cool things are if you put a rudder on the outer winglet you get good bang for your buck, and you can have both wings pretensioned. this will stiffen them further. i would love to see a full size electric aircraft with glide characteristics of 20-1. and i saw a guy who made a maglev planetary blade so you get venturi effect through the center, and make most use of the outer edge of a fan for thrust. between the 2, subsonic travel should be extremely cheap.

@BasedF-15Pilot Год назад

Your bottom truss continuous spar will be stronger in a continuous and smooth U-shape so you can take advantage of the arch and keystone strength and load distribution. (Think bridge or old school archway) It looks like your current design uses multiple pieces with a 30 or so degree angle connecting a smaller fuselage piece with the longer wing connection pieces, and while it looks well made, the load will be concentrated on the angles.

@franzperez9145 Год назад

Great Presentation Questions 1. Did you get a longer range distance with the truss brace than you would without it? 2. The opposite propellers are better performance than a single propeller on each motor? Does it consume same current ? 3. What % of weight loss reduction did you get with the truss brace ? I would imagine that you conducted separate tests on the UAV. That is, one with the truss brace and one without it?

The lightweight PLA is very temperature dependent, including the temperature of the surroundings. It will foam almost none at 190C and a LOT at 240C, I have to turn flow down to 40% when turning the temp up to 240 as it will foam a lot more. Heat causes a chemical reaction releasing CO2 that gets trapped in the PLA, hence my reference to foam.

On the subject of the micro FPV plane. Dropping it out by the side isn’t the best for controlled flight. Dropping it with the fuselage horizontally parallel to the mothership is best. With this said, having it launch with 3 to 5 degrees nose down may provide better initial control. Testing that could be a wonderful project.
