As everyone probably has noted the delivery is really closing in so yesterday we decided on trying to do three different tests, all of them with ejection system as a common dominator. First of was the top plate ejection system test. This system has been the focus for a server amount of testing. The system is important since it covers the parachute, when activated the parachute is exposed to the surrounding air. This time the focus was how the dynema rope moved. The test was successful and ca be seen in the following video.
Next up was the spring ejection test. This test have been performed earlier but the big difference this time was the use of the distance ring which enables another cm of tensioning. It also secures that the spring gets pressed down in the gully fully. The video covering the ejection can be seen below.
Last of during the night was the long term ejection spring test. The idea is to ensure that the system does not lose tension during a longer period of time. This also means that we won’t have access to the system until next monday when we also will perform a new ejection test to ensure that we get the same ejection force after that the spring have been compressed during a longer period of time.
