propeller_map-based

Map-based propeller

This project provides functions and Simulink models to compute the forces and moments of a propeller based on a map. Data of multiple maps of APC propellers is also provided.

Motivation

The propeller thrust and torque are not easy to model. However, there are available maps that provide good results.

Installation

• You must install LADAC (you need the Curve Fitting Toolbox).

Example

Run the example script and read the comments.

How to use?

Simulink:
You should initialize a propeller struct that contains the propeller map and also the inertia and the direction of rotation.

prop = propMapLoadParams( 'propMap_params_default' );

Then you can use the struct to parametrize the available blocks in the library (e.g. Map-based propeller fixed to airframe).
