Nevada2 is a purely 3-row glider with only two main lines on each side due to our well proven Gradient DD system. It has only 62 line attachment points. Thanks to that, we achieved the lowest possible number of lines and total line consumption. By a progressive diameter gradation of the unsheathed upper gallery lines and by reduced binding of the brake lines the total area of lines and their aerodynamic drag are minimised.
For a great transfer of forces from the lines to the whole canopy Gradient used so called Gibus Archs reinforcement, small archs-shaped nylon strings located in the loaded supporting ribs of the B and C rows running chord wise down the rib. The nylon strings in the C diagonals help to smoothen the trailing edge. The leading edge is also smoothed out by nylon strings which are, in case of necessity, easy to replace.
To achieve a good pressurization of the canopy in the whole range of speeds Gradient has developed a new style of cell openings called the VO system.
This style of openings has a very high efficiency in the whole range of angles of attack. It ensures very fast filling of the canopy from the middle towards the ears, which makes the launch and potential collapse recovery quick and easy. It also limits the airflow from the inner space of the canopy towards the upper, suction surface and thanks to that Nevada2 does not lose the climb rate and the forward speed during the flight in thermic and turbulent conditions.
