I am currently designing a Simscape Multibody model of my drone. My drone is a three-armed device, which somewhat resembles the rotors of a helicopter.

The drone is supposed to rotate around itself, using a motor on each arm. Furthermore, each arm will have a wing attached to produce the lift required.

The initial purpose will be to control the RPMs of the motors as well as the pitch of the wings.

Currently I have a model without the wings, so I am looking for a way to model wings that do have some aerodynamic properties, that would be able to create some force upwards (lift) from the spinning motion.

How can I integrate wings (or other forms of artificial lift) in to my model?

  • This reads as you are looking for us to do a massive work. SO will help with specific problems, not with entire projects – Ander Biguri Apr 02 '20 at 11:20
  • You're completely right! Sorry for the inconvenience. To be more specific I guess my question could be whether or not Simscape has blocks that can be customized in regards to its physical properties ie. have it create a force in one direction dependent on another objects velocity. – Jonas Brondum Apr 06 '20 at 09:59

You have several options:

A) Use Aerospace Blockset for ready-to-use aerodynamic forces

B) Compute your own simplified aerodynamic forces (with Simscape Physical-Signal blocks or Simulink blocks) based on relative orientation, cross-sectional area and speed of your solid wrt the air.

Both options would require sensing the relative orientation and speed of the drone, using the sensing option on the 6-DOF Joint.

Here's an example of using Simscape Multibody together with Aerospace Blockset, but for ground vehicles.

  • Thanks! I really appreciate the answer. I went with the second option and my model (however simplified) seems to work the way its intended! I did opt for the Revolute Joint for my wings rather thant the 6-DOF Joint, since the wing has to be constrained in its angular displacement. – Jonas Brondum May 12 '20 at 14:40
