parachute wing stretched out by quadcopters

the quadcopters can pull the ends up or down then you pull the strings

Once the parachute's shape is set you use it just like any other Ram-air parachute's airfoil.

its folded and opens only by the pulling of the quads giving it the desired shape.

An actual trial with this idea http://tenrandomfac...r-Parachute-001.jpg
The quadcopters are too small to be seen in the image [pashute, Nov 04 2021]

Like this? https://www.festo.c...up/en/cms/10244.htm

       Say what? You link a picture claiming it's "An actual trial with this idea." Does that mean you're posting something you know already exists - and if so, did you actually create it or are you pointing to someone else's work?   

       Or by "actual trial" do you mean that's what you'd like it to look like?

       So instead of hands pulling the control ropes you use quad copters? Why not just use motors attached to the payload? Way more efficient.   

       If I'm understanding you correctly.

       Do you mean a rapid deployment system for the chute, so it can go from packed to working extremely quickly? Wouldn't need "quadcopters" per se, just 4 individual ducted props, well tethered for directional stability (& probably jettisioned after use to save weight & tangling...).

       // rapid deployment system for the chute //   

       That in itself - no matter how you do it - may be a bad idea. A lot of work goes into designing parachutes that open "fast enough" but not "too fast" - to avoid damage. To protect both the chute and the user.   

       In fact, the article that pashute swiped that picture from says exactly that: "The deployment of ram-air parachutes was originally so fast that is was dangerous, however, they have since been designed so that a slower deployment speed is achieved to avoid body injuries."

       [a1], I think [pashute] was pulling our legs with his description of the link; if you look at the page the picture comes from, it's just a list of facts about existing ram air parachutes. Obviously.

       Seems like the wrong category, too. Is this the vehicle? How do you determine the shape? Too many unanswered questions?

       Yes [pert] was right, but I was joking, hoping to bring smiles, because I thought the idea was clear, and definitely did not mean to piss any of you off.   

       Ok, clarification; The idea is for a hang glider type of parachute, which could be very large. You don't need to unfold it. You don't need to spread it out and you don't need wind.   

       An extra feature could be that pulling down on the parachute (perhaps even with a motor), it could add energy to the uplift motion, and then the quads could bring up the middle while the upwards thrust is not pulling the middle down, then to the sides creating some sort of large "ornithopter".   

       There are kinds of sea creatures that seemingly swim like that (but not with quadcopters of course).

       // There are kinds of sea creatures that seemingly swim like that (but not with quadcopters of course) //   

       Yes they DO have quadcopters. Just too small to be seen.
