This was a successful test that used 0.2 grams of black powder in the piston and 3x 6-32 shear pins. Webbing was used to connect the sections and the rocket contained a drogue and main parachute. Webbing lengths were not representative but were merely a mock-up of the planned webbing lengths (excluding a load path for the tender descender, which was not included in this test). This test did not implement any form of flight avionics. Following the test, we also performed a tug-test on the parachute (which was packed in a loose z-fold inside the deployment bag; Unknown User (janssonm@mit.edu) check terminology on this), the results of which are summarized below.
Test Case | Approximate Maximum Force (lbs) |
---|---|
Fish scale attached to drogue shroud-line quicklink; pulled main parachute out of cup. | 4.52 |
Held the top of the deployment bag in place; attached the fish-scale to the main parachute's shroud-line quicklink; pulled main chute out of deployment bag. | 9.02 |
