Hello,
I'm designing a rocket that's a 98mm minimum diameter rocket. The rocket is for the Spaceport America Cup which has us get 8.8lbs to a specific altitude. Our altitude is 30,000 feet. Due to the size, we end up going supersonic for a portion of our flight and this causes the Cp to shift. I'm looking to see if this is going to be a problem for our design and if so how to go about accounting for this. We end up reaching a max speed of about Mach 1.5-1.9. We are also going supersonic for about 10-15 seconds. Our rocket is also only about 10 feet long and weight about 50lbs with the motor. Our fins are going to be made out of Aluminum from Max Q aerospace. We are also using a 6GXL motor that we are designing and building. I've attached our current rocksim design. If anyone can help me, I would appreciate it.View attachment SAC 2017 current design.rkt
