Standarized Cargo / Personal parachute

[Silver_Dragon]

In the latest images of the ASC C-130, I've seen that the parachutes appear to be poorly modeled when they release their payloads. They appear to be either too large or not deployed properly.

Since it's unknown whether the parachutes are made by ASC or ED, it would be helpful to know if a generic parachute model is being used for payload deployment or if a specific one is being attempted.

I've been checking, and the payloads use Mills parachutes, in the following versions:

• G-11 Parachute:

  • Models:
    • G-11A: Rigged with no centerline and uses two M-21 reefing line cutters with a 2-second delay.
    • G-11B reefing: Rigged using 100-ft (30.5m) centerline to pull down canopy vent and four 16.5ft (5m) M-21 line cutters with 2-second delay.
    • G-11C: Rigged using 100-ft (30.5m)centerline to pull down canopy vent and two 10ft (3m) M- 21reefing line cutters with 2-second delay.

A video of a C-130 deploying cargo, in which you can see several pallets with fuel canisters launched from the cargo hold. You can see that the parachutes (I believe they are G-12 parachutes) are attached to a guide line, and when they reach the end of the ramp and drop from it, this guide line breaks the upper canopy, releasing a small parachute that is responsible for deploying the main parachute. We also see that the parachute's opening is not automatic, but the initial parachute pulls the main parachute bag and deploys it. You can also see how the main parachute inflates and stops during the fall. The good thing about this video is that there is an external shot of each release, showing the shape the parachute takes on its descent.

Other video, show procedures and deploy cargo by parachute extraction methods.
