Foam cores inside rotor blades
A lot of rotor blades have soft foam cores. Does anyone know how the soft foam inside a blade is fabricated? Are they hot wired to shape, then layed in before the two halves are brought together?

Before pressing the two half, the process put the soft foam liquid inyected... I presume base on similar processing on airplanes...

Generally the cores are cut to the blade profile by hot wire or extrusion. Squirting liquid foam into a hollow blade deforms the blade skins as the foam cures.
