Hello, I'm a member of the rocketry project team at my university. Part of our project is the deployment of a payload and I have been asked to work on calculating the trajectory of the payload units upon their deployment from the rocket. The team lead wasn't able to give me much guidance on how to begin to approach this, and I'm not entirely sure myself how to start. What would be the best way to begin working on this? Is there an aerodynamics text someone can recommend? If it's relevant, the payload is basically a cylinder with three triangular wings. I will be grateful for any help.
