Velocity on Chute

[Woody's Workshop]

What is the recommended velocity of a rocket under parachute recovery.
On my sims, I'm getting about 18' per second on a 12" chute.
Is this too fast or slow, or about right?
I use to know the rule of thumb, but I have forgotten after 5 years off from using RocSim.

15 to 20 on average, depends on landing surface and rocket material.

You know, the one I had all the problems with... syyyy

In ROCKSIM you can convert to MPH I usually stay between 8-10 mph, but then again I launch at the lake bed which is like asphalt. You can always go up on your chute.

I have hay fields to land in. Drifting is a problem because of trees.
And the JLCR won't fit in a BT-55.

Maybe a streamer

18 FPS sounds good for many ranges. I have a few I like to bring in slower because of fins and pointy bits hanging off the back (or, in the case of Bucky Jones, bring it in horizontally at a crawl).


Later!
