Design Possibility

[Bruiser]

So if a person was interesting in designing a rocket similar to the old Estes Manta Bomber is it possible in OpenRocket or Rocksim?



I am thinking about the pods on the wingtips. The design in my head actually has "winglets" that have a pod on each.

I want to try simming it so I can see how having the motor forward of the most aft part of the rocket affect the CP and CG...

Current version of OR can’t do it, so Rocksim is your better bet.

I know rocksim can do fins off of pods, not sure about tube fins. For that matter they say they can do pods off of pods. To my knowledge neither will do a nose cone like that. You would have to approximate it with a transition and larger nose cone.

RockSim can do everything in that design except the nose cone.

To do the aft section, make the 2 fins coming off the rocket, add a pod to each, then add a body tube to the pod and then add a ringtail to that body tube. Might take a little trial and error to get the sweep on the tube fins right, but it should all work and simulate correctly.

The one thing it won't be able to account for - how will those fins hold up to a lit motor just a few inches in front of them? Probably fine if it has been done before, but you may want to consider different materials incase.
