GLIDING-TYPE PARACHUTE Russian patent published in 1995 - IPC

FIELD: manufacture of parachutes. SUBSTANCE: gliding-type parachute 1 has cords 2 and canopy 3 which includes center-wing section 4 and wing panels 5. Each wing panel 5 has lifting surfaces 6 and 7 and form-shaping members 8. Each wing panel is tapering towards tips 12. Center-wing section is made in form of wing 13 formed by lifting surfaces 15 and 16 and form-shaping members 17 and slotted external-aerofoil flap 14. Profiles of form-shaping members 8 of wing panels 5 have lesser magnitude of maximum relative center-line concavity as compared with that produced by form-shaping members of center-wing section 4 which makes it possible to reduce induced drag of parachute in flight. EFFECT: improved aerodynamic characteristics, enhanced stability and reduced usage of materials. 3 dwg
