Data and code for investigating the feasibility of airborne wind energy on Mars in two contributed book chapters [1,2].
Scaling study [1]
The two files are an Excel sheet mcd_data.ods with the tabulated data of the Mars Climate Database v6.1 for the Viking 1 and Arsia North sites and the file scaling.py to compute the scaling factors from the simplified relations given in the chapter.
Performance analysis [2]
The file powercurve.py generates a continuous power curve for a pumping airborne wind energy system in three wind speed regimes. The control strategy was first proposed in [3] and was extended in the chapter to account for constant elevation angles during the reel-out and reel-in phases.
In contrast to [3], the reel-in phase is modeled for constant lift-to-drag ratio of the kite, resulting in a reel-in elevation angle varying with the wind speed. This setup is more appropriate for soft-kite systems with slow actuation and a required safe distance from a negative angle of attack.
The file powercurve_const_beta_in.py contains the alternative implementation, outlined in parts already in [3], with a constant reel-in elevation angle, resulting in a lift-to-drag ratio that varies with the wind speed. This implementation might prove helpful in fixed-wing kite systems with fast actuation that can fly at negative and positive angles of attack.
