Assumptions and Constraints

Test blades must be:

• Cost effective: fall within the budgetary restraints of the ORPC project

• Accurate: 0.1° angle of attack variation, .01” max error (desirable) in camber

• Easy to manufacture: can be obtained within a reasonable time period preferably from UMO campus, MMA campus or local contractor

• Strong: Adequate end fixity to eliminate blade rotation, limit midspan deflection to negligible amount, ate trailing edge fatigue failure

• Easy to change blade profile (especially camber) in subsequent generations but limited to straight not helical or curved blades
