    Altitude to expect on a Estes F engine?

    Hi all, back again with another(probably dumb) question. I've been designing my next rocket in OpenRocket, which flies on an Estes F15-8. The apoapsis in the simulation is 454 meters, and I was wondering if this was an average apoapsis for this kind of motor, or if I just did something wrong(I...

    4" Mercury Redstone File?

    Hi all, Been away from the forums for a long time (more on that later), and I'm back with a question... I'm finishing up a Boyce Aerospace Mercury Redstone builder's kit (4" diameter) and need a Rocksim or Open Rocket file. Does anybody have one? Thanks!

    Open rocket stability number?

    Hi all, I just got Open Rocket to simulate an F powered rocket that I'm building, and for some reason, I can't get the stability number past 0.6! I've tried everything. Any ideas on what to fix?

    Help With Fins In OpenRocket

    When I view my rocket design in unfinished mode the fin look like they are not flush with the air frame. Can anyone suggest a fix.

    TARC Questions

    Hi everyone, I'm leading a TARC team for the first time this year and I had a few questions. 1. We are using OpenRocket to model the rocket and everything looks fine but the flight time looks a little unrealistic. We are using two body tubes and the weight of the rocket is around 300g right...

    OpenRocket tips?

    I'm fairly new to rocketry, and my professor wanted us to first simulate the model rocket apogee on OpenRocket, then use an altimeter to check the actual apogee and compare the two. This was so we could use OpenRocket to design a higher power rocket in the future. But on some occasions, the...

    Pitch rate integration in OpenRocket

    I was writing some code, which would take data from OR to test a few algorithms. In particular, I needed pitch, yaw and roll rate data. However, when I checked OR, I found something very strange. Pitch rate (and probably roll/yaw rate) are not continuous. In fact, if you invert the data...

    Estimation of moment of inertia and CG of model rockets

    Is there any open rocket software which can give moment of inertia and Center of Gravity of rocket system. OpenRocket is able to give CG output but i am not finding moment of inertia data.

    Fin Size Issues in Open Rocket

    Hi all, I am currently designing my own level 2 rocket and I am having issues finding a proper fin size that works. I have read that generally you want your fins to have a root length of 2 calibers, a tip length of 1 caliber, and a height of 2 calibers When I add fins of this size to my...

    Center of Pressure in Open Rocket

    I have been trying to calculate the Center of Pressure of a model rocket with and without fins using open rocket. However, whenever I take away the fins the center of pressure seems way too low. I calculated the CP to be 9.22 inches by hand (by using the areas and distances of a 2D cross...
