This isn't "Morphing" as most would describe it

[bigskip2121]

uh I already built an F14 RC model that does that and I only went to High School?

[BR5499a]

@bigskip2121 Yes, we can tell from your grammar.

[dawsondrew69]

Nice! Is it just the skeleton of the machine, if so what material are you going to cover the wing in so it can form with the extending wing components?

[PearlofRocketland]

Interesting Design concept. That is a tough design challenge. What hardware did you use for linear actuation?

[UGotKilledByACamper]

Wow....A college designed that??? I mean come on, anyone can watch JayJay the Jetplane and come up with that design.......Pffffffftttttttt

[loocky44]

Nice project guys, some questions:

What is the maximum/minimum wing area ratio that you can get?

the advantajes in the airspeed ranges is greater than the weight penalty?

[hawker445]

thats boring, when i get in to aerospace engineering im going to assessable group and make a Reno airracer in the sport class

[fatqwert200]

wow thats the reason why i didnt go into that club im an aerospace engineer but i wouldnt waste my time id rather build something thats new. i could do that in the 8th grade, anybody could

[Meshkka]

@fatqwert200 You're right in 1 aspect, yes anyone with any decent brain cells could build that.

However, you're completely wrong if you think this is easy to do the right way. You have no idea how much code, cfd, fea analysis, electrical and mechanical work goes into building anything with 'variable' wing design (if done right). You'd think if an 8th grader could do it, defense companies wouldn't be spending millions of dollars on similar research projects.

[highseascaptain]

That's pretty lame and not morphing. That's called swing and extend in kindergarden.

[s2thec2t]

@danwes10 with this extending wing where is fuel going to be stored. most acft hold fuel in the wings. with this extending wing you would lose alot of the fuel storage area which means shortened flights

[s2thec2t]

b1 bomber and f14 do the same thing

[danwes10]

@s2thec2t  lots of planes have sweeping wings, however, none that I know of can change their wingspan and aspect ratio by simply having the wingtips extended. That is a huge advantage when it comes to induced drag and subsequently range etc.

[whtswrngwthupeople]

cools ideas but nothing new, ever heard of the F-14 Tomcat, does the same thing

[devilzmantis]

DECEPTICON!!! RUN FOR YOUR LIFE!!!!!!!!!!!!!!!

[mitscientist]

Needs some damping at the wing joints so they dont collide with the air frame

[xpanco]

will it take it off?

[JustGoFly]

Looks good on the bench. Sliding the wing back like that will make the plane very nose heavy. You'd need to slide the whole assembly forward as the wings close back, or put a slide in the system to adjust the weight back as the wing slides back. I imagine all the electronics to do this requires the plane to fly very fast to counter the weight. Huge fuselage must be packed with electronics. You are going to need a big power system or at least a huge propellor.

[Roseneck12]

with making the wings longer the centre of gravity will be put further back which should make it less nose heavy

[danwes10]

@JustGoFly how can weight shifting aft cause the plane to become nose heavy?

[JustGoFly]

@danwes10 Shifting weight aft certainly does not cause nose heaviness. But shifting the WING aft moves the balance point, which transfers weight to the nose.

Make sense ?

[LTF85199]

@danwes10 that answer is in you question..

[danwes10]

@LTF85199 Because the lift is shifted rearward?

[GjonetoTV]

great invention...i want to see it fly

[angrygunsmith]

intereseting concept, but i think its a waste of time, you cant have one plane that is great at everything, you just cant.

[supergooddeal]

That is a very interesting concept.. Same rule applies when I build a boomerang.

[datzfast]

genius

[alex681219]

very nice!!! /watch?v=CiFNqeDQeJ8, is a torque wing very impresive, and the sistem is more simple, you can mix all and make a new one...good look
