Unique design and study tools

While there are many effective tools for computer-aided design and simulation adapted to heavier than air aircraft, none can perfectly model the behavior of hybrid airships combining aerostatic  and aerodynamic lifts; especially when these airships present a wet surface of over 500m².


The first challenge faced by VOLIRIS’ research team was to develop adequate tools capable of modeling the most effective envelopes in terms of drag, lift and stability. They had then to demonstrate their behavior and performances during testing in a digital wind tunnel and a flight simulator.

Having been involved for 7 years in the development of innovative lightened airships, VOLIRIS has internally developed a full range of digital tools and their associated bibliography.


But as nothing can replace the feeling of a pilot and actual data, it is essential to create real prototypes to compare, validate and refine the mathematical models and to supply bibliographic resources.


To do so we developed five prototypes over 6 years. Three of these are used for flight tests campaigns. They can be man piloted or used in drone mode.

This unique know-how has allowed VOLIRIS to master the whole process of creating a lightened hybrid aircraft.

Thanks to our extensive knowledge of the geometry of envelopes, their volume change and their flight controls, plus our experience of operating lightened airships, VOLIRIS has become a major player in the field of airship research and development. This wide knowledge has put us in the position to offer a customized solution to meet the logistical needs of clients.
