System that creates a complex fluid mechanism over a blunt body with and without a decelerator and with regard to a total aerodynamic drag

A method for creating a blunt body with optimized performance, the method comprising:

• creating a first blunt body model without a deceleration device;
• creating a second blunt body model with a deceleration device integrated into the second blunt body model;
• implementing analysis on the first blunt body model and the second blunt body model through use of a computational fluid dynamics module, wherein the analysis is based on fluid flow;
• developing a first contoured plot associated with fluid flow around the first blunt body model;
• developing a second contoured plot associated with fluid flow around the second blunt body model;
• and
• analyzing the first contoured plot and the second contoured plot to determine effects associated with an inclusion of the deceleration device into the second blunt body.
