speed

Hello. I want to use Open Rocket to design a fast, light, and skinny rocket that uses a D motor (I could change my mind and use a different motor depending on the design). What I need help on is understanding what characteristics of a rocket allow it to be fast. Are there any 'secret' things I...

Hi Folks, I'm simming a collection of mid power rockets of interest, and while OR hasn't given me any warnings yet, how slow is too slow when looking at velocity off the rod? 5 m/s? 6 m/s? etc. Thanks!

Due to quite a few mess ups, my rocketry design team is struggling to meet rail exit velocity requirements for a competition. What are some ideas you guys have to help improve rail exit velocity? We are currently adding fillets to the fins to help reduce drag.

Hi friends. I have a problem. I need speed of 25 m/s for lounchrod but my design speed is 32 m/s. If I increase mass, altitude is falling. How can reduce the lounchrod speed? Thanks friends:(
