I'm working on a project in a computational science class that I am in. I am using 3 different nose cone shapes and simulating each of them with different lengths to find optimum nose cone lengths. However, I'm running into weird numbers when I'm simming them.
A conical nose cone 3.1 inches wide and 1 inch tall sims to a bit over 7K.
An ogive nose cone with the same weight and length and all sims to almost 13K.
The rocket is staying subsonic throughout the whole flight.
Does anyone have any ideas how I can get more realistic results? I would just live with it except it's saying that an optimum Ogive nose cone is about a quarter of an inch tall for a 3" diameter nose cone. And just off of a back of the hand sim I KNOW that's wrong.
Any advice?
Thanks all!
