open rocket

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...

Hi, I'm gonna ask you a few questions about Openrocket 1-How is the shock cord passed under the useful load? 2-How does Payload fall apart from the rocket? 3-Can you link to a detailed video or forum about open rocket?

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...

Hello. I'm trying to design my own rocket. I recently downloaded Open Rocket, but am unable to figure out how to launch the application. I've looked on the Open Rocket web site , but was unable to find any clear instructions. Can anyone please point me in the right direction? ( I am using...

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.

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...

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...
