Hi TRF colleagues,
I am running experiments in OR in which I simulate the use of a JLCR. I am conducting my simulations on a LOC/Precision Warlock, and I am using a streamer to model the JLCR. I am setting the JLCR to deploy at an altitute of either 100 or 200 metres.
Here is the issue. I am having great success with a number of J-impulse motors when I don't use the JLCR, but I am not succeeding when I do deploy the JLCR. In my opinion, however, I don't think that the results make good sense. The warnings all state that the recovery device deploys at high speed. Right, the main parachute deploys as the rocket rapidly descends — and we know that is going to happen, because that is the point of using the JLCR. I think that the more telling statistic is the ground-hit velocity — and all of those are quite low.
So, I think that the bottom-line message provided by OpenRocket gives a false warning — and I say this as a big fan of OR.
What do other people think?
Thank you.
Stanley
