Engineering:CEA-308
The CEA-308 is a Brazilian sports aircraft designed by Professor Dr. Paulo Iscold,[1][2] that beat four FAI World Records with pilot Gúnar Armin Halboth.[3]
Design and development
The CEA-308, is an aircraft composed of fiberglass and wood, covered by extruded polystyrene foam plates. The wing spar is made of freijó, manufactured in plywood. A 64 HP Rotax 532 engine was used for flight tests, and later on a 100 HP engine and a three-blade propeller, both built by Hirth, were installed, enabling the aircraft to reach speeds of up to 400 km/h. After some time it was decided to replace the system with a Jabiru engine and new propellers by Catto Propellers, which allowed the aircraft to break four FAI World Records and remain installed to this day.
