The SK-94 is a backpack rescue parachute designed for emergency evacuation from various aircraft, including gliders, airplanes, powered paragliders, balloons, and helicopters. It can be optionally equipped with a dedicated static line and pocket system (part no. 02.70.00.00 for the pocket and 02.80.00.00 for the static line), which allows the parachute to open automatically upon separation from the aircraft.

Technical Specifications:

Spread canopy area: 51 m²

Maximum deployment speed: 270 km/h / 145 kts
Maximum deployment speed (with min. 3 sec. delay): 350 km/h / 189 kts
Minimum jump height during level flight (Vmin=130 km/h 70 kts): 70 m / 230 ft
Minimum jump altitude from a hovering helicopter: 150 m / 490 ft
Descent speed (70 kg load): 3.6 m/s / 12 ft/s
Descent speed (100 kg load): 4.4 m/s / 14.5 ft/s
Forward speed: 2 m/s
Maximum 360° turn rate: 12 s
Dimensions when packed (length x breadth x height): 550 x 400 x 85 mm
Weight: 7.5 kg / 16.5 lbs
Repacking interval: 1 year (365 days)
Service life: 20 years from the date of manufacturing, including storage, transport, repairs, and general technical condition. After this period, the parachute must be decommissioned.

Usage Features:

The SK-94 parachute opens when the release handle is pulled. A spring-ejected pilot chute inflates in the airstream, creating drag that pulls the main canopy and suspension lines from the container. Once fully inflated, the pilot chute deflates and remains connected to the canopy. The parachute offers excellent in-flight stability and easy steerage via steering grips attached to the risers. Airflow through a net-covered slot at the canopy rim provides forward speed, aiding in choosing a suitable landing spot.

Procedure during a jump:

Disconnect from headsets, oxygen installations, etc.
Open/eject canopy or emergency exit doors.
Unfasten seat straps.
Jump clear of aircraft parts.
After successfully separating from the aircraft at a safe distance, pull the ripcord release handle.
Once the canopy opens, check steerability:
- Unlock steering handles, grip them, and pull down.
- Pulling the left steering line turns the parachute left.
- Pulling the right steering line turns the parachute right.
Check wind direction (e.g., via smoke).
Use forward speed and steerage to choose a glide direction (downwind if possible) and landing spot.
Immediately before touchdown, pull legs together and bend knees.
After landing, deflate the canopy and release harness locks.

Procedure after a jump:

Deflate the canopy, clean it of debris (twigs, etc.), stretch it if possible, tuck it into the container, and tie it with lines.
For transport, wrap the parachute in a cloth, foil, or large garment.
After deployment, the parachute must be carefully inspected by a qualified SK-94 parachute packer to determine its fitness for further service. The parachute can be used many times without limitations, provided it is maintained according to these guidelines.

Parachute Components:

Ripcord release handle (Cat. No. NA-05.00-1): Consists of a metal handle, a steel ripcord with two pins, and a stopper.
Pilot chute (Cat. No. 02.30.00.00A): Pulls the main canopy and suspension lines from the container. It effectively closes the container during packing. Made of low-permeable fabric (approx. 0.5 m²) with an integrated spring, net suspension lines, and an apex cap. The apex cap has upper and lower parts, with the lower part containing a conical spring, Velcro webbing for rubber bands, and a webbing loop for securing the canopy and net.
Bridle (Cat. No. 02.40.00.00): Connects the pilot chute to the main canopy. A bridle sleeve covers the bridle and, when pulled over the canopy apex, closes the vent opening to accelerate inflation. During inflation, the sleeve moves down, opening the venting hole to stabilize airflow.
Canopy with suspension and steering lines (Cat. No. 02.10.00.00): Comprises 24 gores of fabric with webbing. The canopy rim and lower parts of three rear gores (propelling slots) are netted. A vent opening (0.5 m diameter) is on top. 24 suspension lines attach to the canopy rim webbing, connecting to two risers (12 lines per riser) via detachable connectors. Two additional line pairs serve as steering lines, connected to suspension lines 4 and 5 (right side) and 20 and 21 (left side), terminating in steering grips.
Steering grips (Cat. No. NA-25): Attached to the risers and connected to steering lines, allowing easy control. Made of contrasting webbing.
Rubber bands (2″ x 3/8″): Secure folded suspension lines inside the container.
Container and harness (Cat. No. 02.20.00.00): An integrated unit. The container is made of permeable fabric with a back plate and four flaps forming an envelope. The back plate has two rows of rubber rings for wrapping suspension lines. After packing, the container flaps are closed and secured with spring-loaded chute closing loops passing through grommets and secured by ripcord pins. Parts in contact with the user's body are padded with permeable fabric for comfort. The harness consists of main webbing connected to the lower part with adjustable rings for hip connectors, to which side and leg straps are attached. Adjustable buckles (visible after cover removal) allow harness length adjustment for user posture and hip comfort. A breast strap is in the breast part. Breast and leg straps can be adjusted via hook buckles (B-12), quick ejector buckles, AB locks, or thread-thru buckles. Two risers on the harness connect to suspension and steering lines. A container positioning system (tightening straps and buckles) is integrated with the back part of the container on the calf and hip straps.
Transport bag (Cat. No. 02.60.00.00): Made of impermeable, waterproof material for storage and transport. Equipped with backpack webbing straps and a document pocket.
Static line pocket (Cat. No. 02.70.00.00): Designed to be mounted with the SK-94 backpack rescue parachute to hold the static line.
Static line (Cat. No. 02.80.00.00): Used to pull the ripcord after separation from the aircraft. Length: 4.2 m [13 ¾ ft].

- Canopy: Knot connecting bridle with canopy must be per manual (sec. 3.1). Fabric, nets, apex lines, and seams must not be damaged.
- Suspension and steering lines: Lines must not be damaged.
- Harness, container: Fabric, webbing, metal parts, and seams must not be damaged. Hooks attaching suspension lines to harness must be screwed tight. Steering lines must be free of twists and entanglements, running through grommets on risers to steering grips (sec. 3.6). Rubber rings must be elastic and of the same type. All harness buckles must connect securely and prevent inadvertent disconnection.
- Ripcord handle: Ripcord must not be damaged, corroded, or deformed. Pins and stopper must be securely tight. Grip must not be damaged, corroded, or deformed (especially at contact points with ripcord).
Packing accessories: Pilot chute packing strap (NA-03), two 'T' pegs with holes (NA-18-2), 5 clamps/weights, wooden ruler, 2 cords (70 cm each), and NSN 8310-10-493-6030 sealing thread or cotton thread (strength ≤ 2.15 daN).
