Drone parachute INDELA SP-35

performanceemergency

- parachute system «INDELA SP-35» is designed for emergency UAV landing with th landing mass of 35 kg; After separation of a parachute container cap from UAV, auxiliary parachute enters the flow, which, after being filled, sequentially stretches the cover with the main parachute from the container, shrouds – from the cell chamber, then – cupola from the cover. Structure and operation of parachute system elements. Main parachute structurally represents “duplex cross” with a vent. Eight paddle parachute cupola is made of F-111 fosta nylon fabric produced in RSA with low level of air permeability ad is strengthened by the frame from LTKP-10-70 belt (with the strength of 70 kgf). Shrouds (16 items) are produced from hi-modulus polyethylene (Dyneema) with the strength not less than 120 kgf. Cover designed for main parachute packing represents a conic container with the length of about 2m. In the upper part, the cover has a loop for connection with VP and in the lower part – two eyelets for coupling of the cover. Honeycomb for placement of main parachute’s shrouds are abut at the side face of the cover. Honeycombs are covered by the skirt. Connecting link designed for joining the main parachute to the loop of UAV link represents a soft link from Dyneema cord with loops at the end. Metal ring is inserted in one of the loops. Structure of INDELA SP-35 system at UAV landing mass of 35kg ensures the following performance characteristics Maximum speed of parachute activation - m/s - 60 Minimum speed of parachute activation - m/s - 15 Minimum height of parachute activation above landing field level - m - 100 Maximum (barometric) height of parachute system activation - m - 3500
