  1. Team Richard Shepherd - Jose Rios - Bruk Sahilu

  2. Mission: • Team Airwolf is set to test the stresses applied to a Helicopter Rotor Blade as it rotates about an axis

  3. Measure the forces acting on a helicopter rotor blade by: • Making a free body diagram of the entire rotor blade machine. • Use analytical techniques to calculate external forces. • Apply the principles of Dynamics to a 3D rotor blade using Solidworks, and Nastran4D • Make design decisions based on simulations that apply Newtons’ Laws • Design Recommendations

  4. Design: • First, the airfoil shape was sketched using Solidworks. A simple extrusion provides a rotor blade.

  5. Design: • Then, two cones were drawn at the base to provide an anchor contact surface and a contact point for the pitch rod to attach.

  6. Design: • Then, the blades will all connect to this rotor hub/shaft.

  7. Design: • After making a few smaller connecting parts it is possible to generate an assembly of the complete rotorhead. The model is now ready to be imported into Nastran 4D.

  8. Design: • And finally, FEA analysis was performed on the blades.

  9. Results: The stresses are concentrated at the base of the rotor blades as to be expected. This is due to a combination of the weight of the blades hanging as a cantilever along with the centripetal accelerations accumulating into concentration points nearer to the hub.

  10. Future Missions: • Potential Lift • Variable Actuators • Blade Collision The End Jose J. Granda, Ph.D.
