The.reshaping.step.can.be.used.to.provide.offsets,.langes,.bosses,.and.the.
like..The.method.and.associated.apparatus.of.the.invention.provide.a.rela-
tively.simple.and.inexpensive.way.of.producing.iber-reinforced.thermoset.
plastics.having.a.variable.cross.section.(see.Figure 2.12).
Figure 2.13. illustrates. the. pultrusion. carbon. spar. for. wind. turbine.

For.the.design.and.manufacturing.of.the.prototype.YUH-60A.UTTAS.tail.
rotor,. the. pultrusion. process 16. was. selected.. A. fully. cured,. pultruded. spar.
design. layout. and. manufacturing. approach. was. developed.. This. is. impor-
tant.because.the.pultruded.spar.consists.of.the.two.blades.being.manufac-
tured.simultaneously.
Elastic.coupling,.which.has.a.signiicant.effect.on.the.dynamic.elastic.tor-
sion.response.of.the.rotor,.was.discussed.in.Smith.(1994). 17
Twist.coupling.effect.depends.on.wind.directions,.variables,.and.angle.of.
twist.change.from.±15 ° .to.±45 ° .(Figure 2.14).
Redesigned. pultrusion. spars. for. wind. turbine. blades. are. shown. in.
Figure 2.15.
We. simultaneously. design. new. spars. to. be. pultruded. for. blades.. These.
spars.are.used.on.root.sections.of.wind.turbine.blades.
