20 Vol.3 No.4 / April 2014 THE CC02 Do you remember your feelings watching military jets fl ying during an air show? We are talking of pre-sequester times in the United States, of course. I remember my emotions and my bumping heart after each low fl yby of an F-15, F-16, or some- thing of that caliber. I'm talking about that screaming, loud jet engine sound, about the airplane that fl ies like lightning down the runway. After such shows, I'd contemplate building some- thing like that in my garage. Claude Chudzik has succeeded in doing that. The maiden flight of the CC02 (CC02 stands for Claude Chudzik, second project; the first was the CC01) was made at Les Loges Airport (LFAI) near Nangis, France, just east of Paris on June 28, 2007. French certification of the aircraft was obtained on May 20, 2008. Getting to this first flight was a long journey. It began in 1987, when Claude won a prize given by the Paris Air Trophée for his CC01 canard airplane. That tiny single-seater, powered by a 25-hp, two-stroke en- gine, brought Claude several thousand francs (about $2,000 U.S.), which was enough for the purchase of foam, fiberglass cloth, and resin for another aircraft. Claude wanted some- thing special; he was dreaming about a sleek, fast, fighter- looking aircraft. Normal sport aircraft with their straight wings did not look fast enough. Military jets looked much faster and had sharp, swept wings, so Claude had "no other choice" than to build a tandem aircraft with swept wings. Because nothing similar was on the kit market, he had to design his own airplane. The only choice was for Claude to design and build his own airplane. As an aeronautical engineer who works for a big aero- space company, he had good contacts in the aviation world. The basic concept of the CC02 was developed in a period from 1987 to 1989. Claude's friend, Michel Barry, allowed Claude to prove the quality of his calculations in Michel's small wind tunnel. For that purpose, a 1:13 scale model was built and tested. Those tests allowed Claude to fi nd out the best location of the lifting surfaces and to check the engine location and the overall airfl ow around the hull. The initial specifi cations were to build an airplane ca- pable of fast cruise with two persons on board and with one The front cockpit of the CC02. On the left side are the throttle and the prop pitch lever; just to the right of it, the rather complex fl ap selector lever. It has an electrically variable pitch prop. The fi rst prop was a fi xed-pitch prop. E A A E X P _ A p r 1 4 . i n d d 2 0 EAAEXP_Apr14.indd 20 3 / 3 1 / 1 4 9 : 4 3 A M 3/31/14 9:43 AM
