The Cold Stowage group retrieves payloads that have returned from the International Space Station via the SpaceX Dragon Capsule. They utilize NASAs C9 Aircraft for this operation and were in need of cargo straps to hold down the hardware used for transportation of the payloads. The HUNCH program fabricated Short, Medium and Long Cargo Retention Straps for this operation.
1 st : The HUNCH program was asked to provide samples of the stitching in both horizontal and vertical directions to determine which, if either was better. Results: The horizontal stitching had a better load capability.
Horizontal Stitching Test to Failure
Horizontal Stitching (1) vs Vertical Stitching () Test to Failure
2 nd : The HUNCH program was asked to provide lot samples, as they fabricated the straps, to be tested for both nominal load and failure loads Results: All lots passed with no issues.
Full Strap w/hooks test
8 Full strap w/hooks, 2000lb load tests 2 Full Strap w/hooks, 3500lbs failure tests
Cargo Straps are used during SpaceX Payload Retrieval Operations
Long Straps restraining a stack of 4 Cargo Transfer Boxes
Short and Medium Straps restraining Powered Payload Transfer Box
