Project take-off

The S-Vision project took off in the summer of 2010 as the successor to the cancelled Impuls project. A regular layout was chosen to simplify the design. Also, the CS-VLA certification basis was chosen, which allows aircraft with a maximum take-off weight of 750 kg and a two-seat configuration.

The conceptual design was completed, but then the project was put on hiatus in the beginning of 2016. The project was then abandoned.

Conceptual Design

The goal was to make the S-Vision one of the most efficient aircraft in its class in terms of speed and range. This high cruising speed was to be combined with the ability to carry scientific research equipment in a dedicated payload bay.

The layout of the aircraft changed quickly in the first steps of the conceptual design phase. This was done to meet all the requirements, and to refine the design. Once the overall shape of the aircraft was determined, and also its performance, it was time to dive deeper into the different systems of the aircraft. Bit by bit, all systems were put into place and designed in more detail. Design parameters such as Maximum Take-off Weight, tail surface, and wing planform were updated one last time. The end result of this preliminary design phase is presented below.
