The stress test performed have confirmed the technical/operating parameters already determined in relevant environment using the first mock-ups built.
5 engine prototypes were used for the tests: preliminary tests on a bench; 8 test sessions on a bench using first a Lycoming propeller and then a Rotax propeller; then the prototypes were dismantled to fix the technical issues emerged; a second set of duration tests proved that the technical issues previously emerged were completely removed.
Interviews to aircraft pilots and flight instructors have demonstrated there is an increased interest in LSA, together with the need of solutions at a lower purchasing and maintenance cost: all that demonstrates how our engine will perfectly fit into this rapidly evolving market.
A patent research and a freedom to operate analysis have been commissioned regarding 4 different topics related to our engine; just for one topic, not even patentable, there is an interference from another patent, but limited to Japan.
All potential risks which can harm the project have been identified, with the probability they could happen. Risk-mitigations have been listed and described, especially for the technical risks.
The business planning has shown positive outcomes (16% increase in turnover) and allowed us to define with precision the required investments and the financial needs.
All these results encourage us to continue the project.
