First post, if I've made any forum Cardinal sins, please let me know.
My rocket is flying higher than it's intended apogee, and because of a maximum weight requirement, I was thinking of simply adding something to the outside of the body tube to increase the drag and hopefully bring the apogee down. Simulations have shown that this could work, but we're worried about the performance of the fins (flow separation?) and the stability implications this might have.
Has anybody implemented something like this? Alternatively, what ways have been found effective to increase profile drag without adding significant weight?
