Three platform generations — not a paper company
The current programme inherits 27 years of engineering, two prior flown airframe generations, and continuous research collaboration with European institutions.
| F10 | 1999–2003 | Designed, built, and flight-tested in Sofia. First-generation airframe. |
| F11 | 2009–2017 | Full rebuild. Designed, built, and flight-tested in Sofia. Second-generation airframe. |
| AcroCruiser | 2017–present | Designed, built, and flight-tested in Sofia. Current-generation airframe — continuing programme. |
Trade-secret & copyright — by deliberate stance
The intellectual property associated with the AcroCruiser airframe and the broader AirCom technology stack is held as trade-secret and copyright rather than under registered patent. This is a deliberate technology-protection stance, not an absence of protectable invention. Patent filing requires public disclosure of mechanism; for an architecture engineered at the design level to resist reverse-engineering, publishing the mechanism would surrender the very protection the architecture was built to provide.
