[R&D] Parachuting Developments in Ukraine
Author Summary
rubbishbailey is in Ukraine
Post Body

Following Ukrainian failures but great successes in Hungary, our largest issue is the paratroopers personal safety from a few major injuries.

  1. Parachute Malfunction (Design Flaws) ~

  2. Rigging Protection (Packaging Flaws)

  3. Oscillations (Design Flaws) ~

  4. Landing Failures (Individual Environmental Error)

  5. Static Line Issues (Failure to Disconnect - Mixture of Design, Packaging and Pilot Error)

  6. Deployment Failures (Mixture of All)

We have developed methods of training to fix and prepare all of these including the design of the parachute itself. One such asset that we will be introducing is the expanded role of the Parachute Riggers. This rigger is required to understand fabrics, hardware, webbing, regulations, sewing, packing, and other aspects related to the building, packing, repair, and maintenance of parachutes and such an assignment is sure to assist and lessen the work-load off of the paratrooper.

No matter.

Parachute Design Flaws (1, 3, 5 6)

It is clear our current units are inadequate and by such we will be adopting a varied design, one of the largest design features we will have is one such button that will disconnect the trooper from their chute entirely, hit on the center of their chest, effectively disabling all the weight holds of the trooper, to be expanded upon below.

Rigging Protection (2, 5)

This has been handled by the implementation of a Rigger.

The New Parachute: ŠŸŠ°-2 (PŠ° ā„–2)


Our new parachute design will have two parachutes. A main chute as well as a reserve chute. The main chute will be the Pa-2 under a steerable, round, 28 gore polyconic dome parachute parachute. It enables and allows troopers softer openings at higher elevations without the issue of damage on deployment conditions. Harnesses will, again, have a new single point release that will prevent drownings from simply the weight attached to the trooper.

Pa-2 Kit

  • Pa-2 Backpack
  • Pull-out panel with static line and hook
  • Parachute harness (adjustable)
  • Reserve pack with pull handle
  • 6 elastic cords with hooks
  • Piece of thin rope to close the backpack

The expected weight of each trooper's parachute and full kit will be several hundred kilograms but with the abandonment of parachutes on landing, they will retain their standard kit.

Our new canopy in the parachute will be domed with a hole in the center (preventing oscillations) but will allow for several new things,

  • the ability to turn quickly with minimal pendular motion thanks to the canopy's 32 foot diameter and a newer drive system
  • the ability to correct landing point overshoots with the unique ability to back up in deep air-brakes
  • the ability to control forward speed and turn rate in flight
  • safely infiltrate all terrains and types of drop-zones from high elevation (due to its low rate of descent, as stated before)

The Pa-2R Reserve Parachute will offer increased structural strength and the following as well,

  • A guarantee of rapid opening with minimal post-inflation collapse at the expense of altitude loss
  • Inflation no matter the malfunction
  • Cooperates with the full main canopy (should it be deployed inadvertently)

Pa-2 Harness

  • Offers an improved and far more comfortable fit, adjustable to the user (as stated under Pa-2 backpack)
  • A design akin to a saddle with adjustment that fits a wide range of jumpers, male and female
  • Comfort pads that assist in the 'jerk' effect of the parachute, preventing muscle strain and adding additional utility to the leg and pelvis braces

All further deployment of paratroopers will be done from inside of the An-4T with static line and hook deployment. On exit of the plane, the line will pull and activate the parachute.


Paratrooper Training Regime

(taken from wikipedia)

A parachute landing fall (PLF) is a safety technique that allows a parachutist to land safely and without injury. The technique is performed by paratroopers and recreational parachutists alike. The technique is used to displace the energy of the body contacting the earth at high speeds. The parachutist ideally lands facing the direction of travel with feet and knees together. At the moment first contact is made with the ground, the person goes from an upright position to absorbing the impact by allowing the body to buckle and go toward a horizontal position while rotating toward the side (generally the direction with the dominant directional speed). When executed properly, this technique is capable of allowing a parachutist to survive uninjured during landing speeds that would otherwise cause severe injury or even death.

While landing under a parachute canopy, the jumper's feet strike the ground first and, immediately, he throws himself sideways to distribute the landing shock sequentially along five points of body contact with the ground:

  1. the balls of the feet
  2. the side of the calf
  3. the side of the thigh
  4. the side of the hip, or buttocks
  5. the side of the back (latissimus dorsi muscle)

(taken from wikipedia)

The few common malfunctions of a parachute malfunction is as follows but are things that with this new system we have accommodated for.

  • Blown Periphery

a type of round parachute malfunction that contorts the shape of the canopy into the outward appearance of a large brassiere. The column of nylon fabric, buffeted by the wind, rapidly heats from friction and opposite sides of the canopy can fuse together in a narrow region, removing any chance of it opening fully.

  • Streamer

a type of malfunction when the main chute which becomes entangled in its lines and fails to deploy, taking the shape of a paper streamer. The parachutist cuts it away to provide space and clean air for deploying the reserve.

  • Inversion

An inversion occurs when one skirt of the canopy blows between the suspension lines on the opposite side of the parachute and then catches air. That portion then forms a secondary lobe with the canopy inverted. The secondary lobe grows until the canopy turns completely inside out.

  • Barber's Pole

A "barber's pole" describes having a tangle of lines behind the jumper's head, who cuts away the main and opens his reserve.

  • Horseshoe

The "horseshoe" is an out-of-sequence deployment, when the parachute lines and bag are released before the bag drogue and bridle. This can cause the lines to become tangled or a situation where the parachute drogue is not released from the container.

  • Jumper in Tow

"Jumper-In-Tow" involves a static line that does not disconnect, resulting in a jumper being towed behind the aircraft.
