Ablation Modeling for Dynamic Simulation of Reentry Vehicles (Preprint)
Abstract
A method for estimating the effects of nose cone ablation on the aerodynamic forces and moments of a reentry vehicle is presented. The method provides a means of generating a rough, but representative model that makes use of interpolated test or prediction data using instantaneous nose cone mass as an interpolation variable. An interpolation function is proposed that can be used to approximate the location of points on the outer-moldline as well as the aerodynamic characteristics between node points. While the changes in overall vehicle mass properties due to ablation are typically small, one can make use of the interpolated outer-mold-line information to estimate mass properties, such as moments of inertia or center of gravity. The interpolated aerodynamic and mass properties provide a means for generating data for dynamic simulations for use in vehicle proof-of-concept studies.
