Can a flat pattern be made of a helical screw flight?

Out of box - nope!
But I know a man that might know how . . . @konstantin_shiriazdanov, what do you think?Philip Thomas - Onshape0 -
We did an experiment with a 180deg helix, worked with paper, but we didn't have the tooling to bend a full scale 14ga sheet.
I'm not sure if it would work in the end, but you can have my resulting document.

Helix is also non developable but I would did what @john_mcclary showed, assuming helical bounds transform into concentric circles of the corresponding length and linear edges transform into radial lines on the flat. It should work well untill the width of the helix is significantly smaller then the length.

Thanks everyone, bit more complex than I was hoping.
