    pop up wing

    What kind of CAD is that? Im looking for a free 3D one. Hope youre not too unwell, Dave

    pop up wing

    Man that sounds bad. Some of the earliest folding wings were radial formats. Perhaps taken from bat wings in nature. The back to back umbrella might work except the protruding post/s and rigging is not conducive to streamlining as you say. The Arup planes of the thirties were v. succesful and I...

    pop up wing

    I'm not sure he was being facetious. Although I myself was thinking more of flying pancakes like the Arup S1-4 series of planes. Wing roots that extend and merge with the circular wings on Manticores drawing rather like strakes would be one possible solution to all of this

    pop up wing

    Manticore. That's one iteration worthy of consideration. The dilemma posed is indeed the way to combine the two qualities rigidity and flexibility for folding down. If we take Manticores format above then add an interplane strut to the centre of each wing panel then provide ram air pressure...

    pop up wing

    I was originally concerned with flexible rodded hoops guys. These are the structures that appear in pop up tents. This might form a circular planform wing if only it could be suitably braced. A circular planform biplane being one possibility presumably

    pop up wing

    A plain circle is pretty low aspect ratio. All the pop up tents attempt to use a structure that is as near to circular as possible although zips here and there allow reversion to a circular rod format where possible for their folding. So we can assume an oval shape with a zip down the centre...

    pop up wing

    Thanks guys. A bit of support in the way of a lifting body and suitable spanwise lift distribution comprising lifting body and Pop up wing 'extensions' as described above. I've not looked at how this was tackled if discussed previously Time to rig is one consideration. I have one idea that...

    pop up wing

    Thanks Manticore. It was actually while I was in the Pound £ store that I saw those Sunshades for car windows. Whilst they were broadly rectangular in outline and had rounded corners they did fold to about a 1/4 of their original area. I in fact lay 2 together and considered just...

    pop up wing

    Anyone ever considered using the technique applied to things like tents or washing baskets to make a folding wing that by twisting can be compacted and erected? The rodding would be around the periphery and parafoil 'cells' would give the wing some Thickness etc. I'm picturing something in...

    Bede BD5 was it a death trap?

    Thanks Added to that v.small aircraft have less energy presumably (MxV), bounce around in rough air, as is often the case close to the deck. No I dont know much about ?Edward Cullen Dave

    All moving Elevator integrated in flying wing?

    Yep I agree Addaon, the thing morphed mid-flight in terms of its mission statement from integrated elevator to car-topable wing. I dont have time right now to look at 'all' the suggestions re similar ideas, and I'm in fact a bit surprised on-one noticed the detail errors in my drawing which now...

    All moving Elevator integrated in flying wing?

    Basically it consists of 7 flying panels all the same outline shape that merge to form a compact bundle less than 10ft across Dave

    All moving Elevator integrated in flying wing?

    Thanks Aircar. I appreciate your kind interest. Given the original requirement to make a car topable wing in 'panels' (which is what I was trying to do) :ermm:I now have formed this (joined wing) format in my list of concepts?:

    All moving Elevator integrated in flying wing?

    Hi Aircar Im not able to access a 3D CAD prog, the one I use is free called CADStd, but it cant I dont think do Orthographic. I will check if this prog. can provide the 3D free as well for free. Im unable to address every point here because of time. But I agree that the structure has to be...

    All moving Elevator integrated in flying wing?

    With respect I dont think youre looking closely enough at my drawing to see either which way it is supposed to travel nor that it is a joined wing, both of which should be evident unless I am failing completely with an audience that is totally unable to read the most basic of technical drawings

    All moving Elevator integrated in flying wing?

    I understand your reservations re. rigging angles, but these depend to some extent on the bending or more precisely the stiffness of the spar. One plan was to tension the rigging wires enough to provide a LE or something to form the LE on. In an attempt to shift the Aerodynamic Center, I...

    All moving Elevator integrated in flying wing?

    Cheers HITC, Heres the latest incarnation, will get back asap re your observations, (time is short right now) Still retaining all moving stab, up front but wonder if prop/shroud should be on front of fus/pod in order to obtain correct CG on an IC version of it. Shroud also adds horizontal...

    All moving Elevator integrated in flying wing?

    I initially wanted a wing with panels that reduced to at minimum 1/4 span (to go on the roof of my car) I wanted to employ an untapered tube spar and flex-wing ability to fold as well, to tension the sail which (maybe) has battens etc, or may employ rigid tip panels Then to find various ways to...
