The concept is described here: https://www.tiira.ch/
Advantages:
- continues power production
- lower mass, costs and complexity of the wing than concepts with wing mounted generators
- automated launch and landing is straightforward
Components
- pair of wings
- generator
- two winches with two tethers
- tilting actuator
Simulation software overview
- Aeromechanical model: KiteModels.jl
Main issue - Aerodynamic model: VortexStepMethod.jl
Main issue - Winch model: WinchModels.jl
- Atmospheric model: AtmosphericModels.jl
- 3D viewer and GUI: KiteViewers.jl
- Plotting: ControlPlots.jl
- Settings, logging and coordinate system transformations: KiteUtils.jl
Tutorials
- For learning to create mechanical models with ModellingToolkit.jl, have a look at Tethers.jl
Control software
There is the old repository KiteControllers.jl, but this needs to be restructured. Suggestions:
- split off the winch controller and create a package
WinchControllers.jl - create a new repo
SimpleKiteControllers.jl
One of the first things to implement would be a path-following controller.
An alternative approach is being developed in the package KitePredictiveControl.jl .
Kite State Estimation The following project implements an estimator, which would be in particular useful to estimate the wind speed at the kites: https://github.com/ocayon/EKF-AWE/tree/main
It currently only supports LEI kites in pumping mode of operation. Furthermore, it is not yet integrated with KiteModels.jl.
