The Gradient Avax is a Czech single-place, paraglider designed and produced by Gradient sro of Prague. Introduced in the early 2000s, it remained in production in 2016 as the Avax XC5.[1]
Design and development
The Avax was designed as a competition glider.[1]
The design has progressed through five generations of models, the Avax, Avax 2, 3, 4 and 5, each improving on the last. The models are each named for their approximate wing area in square metres.[1]
The Avax XC5 employs a unit cell structure that uses a combination of two non-carrying ribs with double diagonal segmented ribs attached to the wing's top surface. The wing trailing edge employs mini-ribs to maintain a smooth profile.[2]
