11. Functional Requirements Lakota CAET Team Capstone Design Presentation
Compressor geometry must not interfere with furling or flow
characteristics
Compressed air transport must be incorporated into yaw
assembly
Compressed air will be stored in pressure vessel
Pressure vessel must exhaust excess air pressure
6 mph cut-in speed
Survive wind speeds up to 120 mph
Obtain maximum power between 8-9 mph
Lakota CAET Team Capstone Design Presentation

12. Nonfunctional Requirements
Must utilize as much existing material as possible
Design must meet AEROMAG’s aesthetic standards
Design must be economically viable
Ten year design life with one scheduled maintenance action
Manufacturing drawings must utilize metric dimensions
