Wind Turbines Fail in Hurricane Conditions Brake Failure Resulting in Blade and Structure Destruction
Brake Failure Resulting in an Explosion Structural Failure Resulting in Collapse
Problem Statement Develop a conventional wind turbine capable of surviving hurricane-force wind conditions. Specifications • Capable of conventional turbine functionality • Capable of survival in hurricane force winds • Environmental-friendly • Economically feasible
Turbine Concepts 3. Darreus Vertical-Axis 2. Savonius Vertical-Axis 1. Horizontal-Axis
Current Technology • Manual Tilt and Cable Method
Structural Concepts 1. Quadruped Foundation with Hinged Tower 3. Hinged-Cable Assisted 2. Reinforced-Traditional
Final Design Horizontal-Axis Turbine Quadruped-Foundation Hinged Tower with Counterweight • Systems • Induction Generator System • Control System • Braking System • Hydraulic Drive System Wind Turbine
Design Advantages • During high winds, turbine not • active • exposed • Structure durable in high winds • Ease of Fabrication and Construction • Ease of Access for Maintenance and Repairs
Design Disadvantages • Debris present at lowered position • Transportation will take longer due to heavier components • Hinge fatigue • Dilemma Height Restriction
Hydraulics 1. Cylinder chosen 2. System designed around cylinder and lift.

Risk Assessment • At night Turbines display flashing red lights Wildlife • Birds • Scientists found that birds simply fly around the farm, or between the turbines; less than 1% are in danger of colliding with the giant structures. • Bats • Attracted to Turbines • Research on an Ultrasonic Deterrent underway
Challenges Encountered • Delays in component procurement • Minor design adjustments for machine shop production • Assistance needed in implementing electrical components • Output of anemometer difficult to work with • Discovery of permanent placement for prototype
Summary • Successful design of turbine system for hurricane-prone regions • Fabrication of a prototype • Structurally sound with little to no stresses that may cause failure or fatigue • Fail-safes implemented to account for any malfunctions
