Title: 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.

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
