Remote Control Helicopter

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 cont..

• 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.

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
