摘要

A German startup and a Portuguese airline are to test a novel drag-reducing wingtip for the Airbus A330 in the first step of a strategy to increase the efficiency and sustainability of in-service aircraft through easily retrofittable aerodynamic improvements.The Aircraft Performance Co. (APC), based in Hamburg, has partnered with Portuguese wet-lease specialist Hi Fly to flight-test a prototype of the multi-finger Trinitair wing-tip on an A330-200. The project is supported by the Mirpuri Foundation, a Portuguese nonprofit focused on sustainability and founded by the Mirpuri family, which owns Hi Fly.Unlike the single surface of the A330's standard winglet, or the dual surfaces of the Boeing 737 MAX's advanced winglet, Trinitair has three aerodynamic elements, or fingers. The wingtip is designed to increase the reduction in drag provided by a winglet while avoiding introducing loads into the wing that would require modification of the primary structure.
