Wing Load Comparison with the e-Genius I
Wing Load Comparison with the e-Genius I

In order to be able to start planning the wing production, the focus in the area of structure was most recently on the wing load comparison between the FVA-30 and the e-Genius.

A particular challenge in the development of our battery pack is the design of a fail-safe thermal management system that can mitigate temperature rise during start & climb and prevent undercooling during 4-5 h of range-extender-powered cruise flight at up to 3000 m, where batteries need to be recharged and remain operable, e.g. for a go-around.
