During the static certification tests the tailplane torsion box including ORPE Technologiya large-sized CFRP stringer panels was tested for bird strike resistance. Besides, the load bearing capacity of the structure under study with inflicted normalized damage up to its total fracture was determined.
“Within the framework of cooperative activities on the development of MS-21-300 airliner the Enterprise of the holding company has mastered the batch production of keel and tailplane torsion box parts from polymer composite materials: the Enterprise has manufactured over 4000 tail unit specimens and fragments. A wide introduction of computer-aided technologies for the manufacture of carbon filler-based polymer composite materials is a distinctive feature of the production process”, said K. Shubsky, Director General of RT-CHEMCOMPOSITE.
