Panthera deset otoček vývrtky

Why ten turns?
Panthera is to become a full Part-23 (FAR-23 and CS-23) certified airplane under the “Utility”, not “Normal” category. This calls for spin testing – a fully developed spin of at least 6 full rotations before recovery is initiated. Tested were all combinations of centers of gravity, cases of asymmety, flaps and landing gear positions, engine power variations etc.) All cases proved to be non-problematic, thus we decided to go the extra mile. Pipistrel doesn’t just recognize the standards and fulfill the minimum level of safety – we want to be a lot better than the minimum! The above video was recorded once the minimum test were passed and we were absolutely certain that all spin cases were safe – and then we went a step further. We expanded the testing for spins to 10 rotations, which happens to be the norm for aerobatic aircraft, although Panthera was never conceived to be one. It was however designed to be superbly safe, and the spin test campaign proved this aspect of safety very well. To demonstrate a 10-turn spin is not necessary for certification, but we chose to do it because of our commitment to extra safe products

Prepreg a jak se s tim dělá

Monday, September 24th, 2012

Co je to ten prepreg a jak se s tím vlastně dělá?
Zvídavá otázka hned od několika čtenářů – asi hlavně modelářů. Na otázku máme velice rychlou odpověď ve formě videa. Materiál se koupí hotový – něco jako kus lina do kuchyně s krycí folií. Na laserovém reklamním plotru se z něj vyřežou střihy, ty se vloží do formy a celé se to upeče v troubě. Výsledkem takového postupu je naprosto stejná gramáž a hmotnostní rozložení jednotlivých listů turbofanu. To, co je na videu, je 5 let stará technologie a je pouhým předvojem nové supermoderní technologie “vrtulí” o které budeme psát za pár týdnů. Enjoy!
