  1. Remote Control Helicopter Group 9 Moiz Kapadia Adam Golembeski Eric Silk Paul DiFilipo

  2. Motivation • A majority of the members are pursuing the aerospace option. • Interested to learn and understand the dynamics of a helicopter. • The RC Dragonfly posed as an appropriate challenge for 4 group members.

  3. How the RC Dragonfly Works • Helicopters generate lift by creating a pressure differential across the blade • The motion of the swash plate regulates the forward, backward, left & right motion • Yaw is controlled by the speed of the tail rotor

  4. How the RC Dragonfly Works con’t.. • Flybars work in conjunction with the swash plate to guide the roll & pitch • Servo motors control the motion of the swash plate • This is a fixed pitch model, meaning the main rotors are rigid to the shaft.

  5. Major Components • Battery Tray • Tail Rotor • Main Chassis and Landing Gear • Main Rotor • Swash Plate • Body

  6. Battery Tray • Mirror, extrude, and cut. • Basic constraints such as axis align, datum plane offset and mate was used.

  7. Tail Rotor • Revolve, extrude, mirror, shell methods were implemented in modeling. • Pin connections. • Gear connections made in mechanism mode

  8. Chassis and Landing Gear • Mirror, extrude, cut, sweep protrusions. • Axis align, datum plane offset, and mate. • Intricate angles were measured to fully constrain the landing gear and support beams

  9. Main Rotor • Contains complex series of constraints including pin, bearing and ball joint. • Simple methods of modeling such extrude, cut and mirror were implemented.

  10. Swash Plate

  11. Helicopter Body • Outlined digital pictures of body with Style Tool, Mirror, Shell, and Extrudes to model the main body. • Cut out of windshield, color, and reassemble.

  12. Problems Encountered • Constraining servo motors • Replicating swash plate movement • Parts needing to be re-measured • Unit corrections

  13. Full Animation

  14. Final Assembly

  15. Thank you Ray for all your help & motivation this semester. Thank You
