How to flatten (unwrap) a curved surface.

Happy xmas.
The pic shows the fuselage for a DH. vampire I am planning to build and fly, in 5mm foamboard.
I have divided the basic shape into sections, and I wish to cut them into closely approximate shapes, which I will hot glue together to replicate the model shown.

Is there a way to take each section in MOI, unroll the surface, and use the outline for a laser toolpath?
