FIELD: aeronautics.

SUBSTANCE: invention relates to parachute equipment. Parachute comprises an axially symmetric canopy 1 with slings 2 made of fabric with different air permeability. Central part 3, making 20–50 % of total cutting surface area, is made of fabric with high air permeability of 200–1,000 l/m²/s, and peripheral part 4, making 50–80 % of total cutting surface area, is made of fabric with low air permeability of 0–5 l/m²/s.

EFFECT: invention is aimed at increasing the coefficient of resistance, reducing swinging and reducing dynamic loads when opening the canopy.
