• Harness - The pack is fastened to the person's back or front with a harness. The harness is<br />

specially constructed so that the parachutist is not injured as the forces <strong>of</strong> deceleration<br />

(slowing down), gravity and wind are transmitted to the wearer's body as the chute opens.<br />

• Rip-cord - A rip-cord is used to open the duck pack and allow the chute to deploy (pop out).<br />

The rip-cord can be used in three different ways (pulling the rip manually, a static line<br />

connected to the aircraft deploys the chute as the person jumps or automatically as the pilot is<br />

ejected from the aircraft).<br />

• Suspension lines - Suspension lines, or shrouds, connect the canopy (parachute cloth) to a<br />

ring on the harness. The line is continuous from the ring, through a seam in the shroud over<br />

the top <strong>of</strong> the chute and back down to the ring again.<br />

Parachute canopies are primarily made <strong>of</strong> high tensile nylon multi-filament fibres, generally ripstop<br />

woven, from 32 to 200 deniers. Ripstop fabrics are woven fabrics whilst using a special reinforcing<br />

technique that makes them very resistant to tearing and ripping. Older lightweight ripstop fabrics<br />

display the thicker interlocking thread patterns in the material quite prominently, but modern weaving<br />

techniques make the ripstop threads less obvious.<br />

Ripstop fabrics have high strength to weight ratio. The smaller tears and rips cannot easily spread<br />

further in the fabric. Air-permeability is one <strong>of</strong> the most important characteristics because it<br />

determines the behaviour <strong>of</strong> the parachute itself, the rate <strong>of</strong> descent depends dramatically on this<br />

characteristic. The fabric should be <strong>of</strong> minimal thickness to enable folding <strong>of</strong> the parachute into a bag.<br />

Harness, webbing, tapes etc are made-up <strong>of</strong> high tensile nylon yarn (denier range 210 to 840 denier)<br />

as nylon has the highest strength to weight ratio.<br />

Market dynamics and key growth drivers<br />

Parachutes can be broadly classified into three categories based on usage: Defence, aero-sports and<br />

space vehicles.<br />

• The parachutes applications in defence are - Emergency Escape Parachute Assemblies for<br />

aircrafts with fixed seats or assisted, escape seats, Personnel Restraint Harness for seated or<br />

moving crew members, Airborne Forces’ Parachute Assemblies including Reserve<br />

parachutes, Aerial Delivery (Supply Dropping) Parachute Assemblies, Aircraft Landing<br />

Brake and Anti-Spin Parachute Assemblies, Parachute devices for flares, markers, bombs and<br />

other munitions.
