Welcome to this post This post will provide you with information regarding the Besiege – helicopter swashplate tuning and Troubleshooting, and we hope you will find this material helpful.

This is a troubleshooting guide to make an otherwise beautiful swashplate function better. It’s a troubleshooting/tuning guide, not a building guide.

Intro

This is a list of troubleshooting and tuning steps for advanced builders. I’m assuming the reader is familiar with Besiege and understands how to build a swashplate.

Example Design Description

This is an example of what I did. The guide is still useful even if your design is different.

• White — static:

  The braces that connect the mast to the base log (red scalling) are used to support the top unpowered wheel. Two hinges are used to provide additional support to the orange cog which powers to rotor.

• Red — mast:

  A tall scallingblock connects the bottom wheel. The wheel’s “ADD PT”, is prioritized, so that the scalling will only connect with the wheel.

• Orange — engine:

  Brace your hands on the powered cog.

• Blurple — swashplate:

  A scaling block. Joint flexibility is used to tilt. Stay in sync without complicated constant velocity mechanisms or an axle block with high inertia.

• Yellow — swashplate Control:

  The yellow wheel attaches the swashplate. Three steering hinges adjust the roll, pitch, or phase shift.

• Blue control rods:

  Translates tilt of swashplate into pitch of each blade.

• Dark Grey — rotor blades:

  The strong spinning block at 0 speed, acceleration. A log to be used for the replica visual. 3 id=’52’ propellers. Two scalling block for the tip. One should be tuned, and the other has a low mass (0.001) for visual.

 

Troubleshooting Guide

Format:

+ to increase | do this
--------------------------------------------------------------
- to decrease | do this

List:

1. Blade Flapping

   + | blade root block scale - |
   --------------------------------------------------------------
   - | blade root block scale + |
   

   (smaller blocks have more flexibility)

2. Dissymmetry of Lift

   + | tip mass + | flapping - | mast mass - |
    | swashplate & control rods rigidity (mass and scale) - |
   --------------------------------------------------------------
   - | tip mass - | flapping + | mast mass + |
    | swashplate & control rods rigidity (mass and scale) + |
   

   (when swashplates & control rods rigid, flapping a blade will naturally reduce dissymmetry of lift).

3. Rotor Speed

   + | power + | power source block support + |
   --------------------------------------------------------------
   - | power - | |
   

4. Swashplate Effectiveness

   + | swashplate end of control rod distance to center + |
    | blade end of control rod distance to blade axle - |
   --------------------------------------------------------------
   - | swashplate end of control rod distance to center - |
    | blade end of control rod distance to blade axle + |
   

   (basic lever)

5. Phase Shift

   + | tip mass + |
   --------------------------------------------------------------
   - | tip mass - |
   

   (gyroscopic precession)

   Correcting phase shift is possible in several ways.

   1. Rotate all the swashplate controls.

   2. Tilt the control rods in order to shift between swashplates and blades

6. Vibration

   + | tip mass - | mast mass - |
   --------------------------------------------------------------
   - | tip mass + | mast mass + |
