Floating aerospace models

 On the link https://erik-engheim.medium.com/calculating-lifting-capacity-of-airships-48df5cd7d147 there is a topic of Calculating Lifting Capacity of Airships - especially on hydrogen and helium 



There is also a ''wiki'' page https://sites.google.com/site/airshipwiki/the-team linked to the SmallBlimps Commuinty forum at http://smallblimps.lefora.com. Whereas the forum is a place for discussing small blimps and the goal of personal airship ownership, this wiki will serve as a repository for any knowledge that discussion produces or uncovers. 




I was not aware that in recent years there was a trend of floating aerospace vehicles. One of those is on the page: https://www.skylifter.eu/technology/ Skylifter is proud of its design: SkyLifters were conceived using proven lighter-than-air (LTA) principles and established aircraft operational practices. They are a new type of airship with a different shape, designed to be Omni-directional; effectively with no front, back or sides.


The one from 2012 is also https://en.wikipedia.org/wiki/Hybrid_Air_Vehicles_HAV_304/Airlander_10 
The Hybrid Air Vehicles HAV 304/Airlander 10 is a hybrid airship designed and built by British manufacturer Hybrid Air Vehicles (HAV). Comprising a helium airship with auxiliary wing and tail surfaces, it flies using both aerostatic and aerodynamic lift and is powered by four diesel engine-driven ducted propellers.
