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.
Design and development.
The Avax was designed as a competition glider.
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.
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.
