CRUCIFORM BLADED PARACHUTE Russian patent published in 2006 - IPC B64D17/02 

FIELD: equipment for flying vehicles.

SUBSTANCE: parachute is formed by fastening together adjacent edges of side blades 14, 16, 18 and 20 for forming three-dimensional canopy 10 at filling it with air; it is square at the top and round over lower edge. Adjacent edges of blades are fastened together for forming vertical holes and openings 36 for escape of air from under canopy and for forming angular nozzles for escape of air flows, thus making it possible to use material for manufacture of canopy possessing zero or close to zero porosity. Connection of adjacent edges of blades near their external ends makes it possible to obtain continuous edge over lower edge of canopy, thus facilitating the process of packing the parachute and enhancing reliability. Nozzles for escape of air flows are included additionally to angular nozzles formed by connecting the adjacent side edges of blades.

EFFECT: stability of descent of parachute within ±5° or even lesser.
