DESIGN OF AN EMERGENT NET SHAPE
FABRICATED THREE BLADE COMPOSITE
ONE PIECE ROTORS FOR CAPEX AND
OPEX REDUCTIONS
Marine Hydro Kinetic (MHK) turbines have shown promise as amethod for
harvesting energy from natural waterways. However, excessive fabrica-
tion and assembly and high life-cycle costs often preclude implementation
of these energy harvesting devices. As such, our design process is focused on
mitigation of implementation challenges by designing a novel low-cost, net
shape fabricated single piece composite three-blade MHK turbine rotor to
minimize both Capital Expenditures (CAPEX) and Operational Expenditures
(OPEX) to enable cost of energy improvements. We believe that we are able
achieve these cost reductions by leveraging our successfully demonstrated
rapid design protocol, underpinned by our team-based concurrent engineer-
ing design approach, whereby we incorporate all key technology disciplines
including selection of materials, implementation of robust design methods,
ply kitting strategies for ease of blade manufacture, recommended non-de-
structive inspection methods and design of test and evaluation methods
from rotor concept design through single piece composite rotor prototype
detailed design. Author’s presentation provides a summary of the three key
emergent processes associated with our prototype design evolution: Design
for turbine rotor manufacturability using computational fluid dynamics and
finite element analysis; single piece composite turbine rotor net shape fabri-
cation protocol and coupon and prototype threshold fatigue test methods
to ensure MHK rotor structural robustness. They envision that this innova-
tive team-based concurrent engineering approach will enable us to reduce
CAPEX by eliminating complex assemblies and rotor machining while mit-
igating OPEX by use of non-corrosive e-glass/epoxy composite materials
and implementing our state-of-the-art threshold fatigue design protocol to
prevent onset of material degradation over the life of the MHK turbine rotor.
