PARACHUTE SYSTEM Russian patent published in 1994 - IPC

FIELD: aeronautical engineering. SUBSTANCE: parachute system includes gliding canopy 1, parachute shroud line set 2, and two (left and right) double-arm levers 3. Lines 2 are joined in strands and attached by their upper ends to gliding canopy ribs and by lower ends - to control lever 4, with canopy left half strands attached to the left lever and canopy right half strands attached to the right lever. Axis of rotation 5 of levers 4 is perpendicular to the plane of symmetry of the parachute system and is connected to suspension system 6 of load 7. Owing to this fact, axis 4 intersects with line of gliding canopy aerodynamic forces resultant action which lays in the system plane of symmetry and runs through the suspended load center of gravity. Two control levers provide for symmetric and asymmetric control of angle of attack of left and right canopy half sections. EFFECT: reduced energy consumption for parachute control. 1 dwg
