Our project
The overall development trend of transport technology can be seen in a transition to hybrid and fully electric vehicles. While this has been made possible to a large extent for road transport, this task is a more difficult one in aeronautical technology. In the aeronautical transport segment there are some early prototype concepts providing fully electrical wing-type aircrafts with a short-range ability of approximately 1000 km. In this context, a related issue is the energy storage using a secondary, i.e. rechargeable battery having a weight in the amount of e.g. 60 % of the maximum take-off weight.

of the project
2003
The StratoWave team was practically among the first in the world to broadcast a sailing regatta live on-line. Half a year later, also in 2003, the first plane in Croatia was connected to the Internet and the first ever email from the air over Zagreb was sent from it, and it was accompanied by a livestream.
2010
In cooperation with the Faculty of Transport and Traffic Sciences, Department of Aeronautics, University of Zagreb, flight and communication tests were repeated up to 20 km in the wider area of Lučko and Zagreb airports, bordered by Zagreb, Samobor and Jastrebarsko.
2014
A stratospheric balloon test was performed, where a livestream was performed at an altitude of 32 km above Zagreb and a total distance of 50 km.
2018
The company StratoWave Connect was founded with the primary activity of wireless communications. In the same year, a Cessna 172 flight with live stream HD video transmission was made as a demonstration at a distance of 50 km between Lučko Airport near Zagreb and Duga Resa.

What does this all mean?
The object of the present invention is to provide a hybrid multirotor propulsion system having high efficiency at low manufacturing and maintenance costs.
The afore-mentioned object is achieved by a hybrid multirotor propulsion system for an aircraft we make.
