TLDR
In this paper, a study was made to determine the accuracy of dynamic stability derivatives as predicted for the North American Navion by several different sources using the results of flight tests as the norm, estimates from wind tunnel tests and several texts were compared.Citations

Parameter Estimation from Flight Data of a missile using Maximum Likelihood and Neural Network Method
S. Singh,Ajoy Kanti Ghosh +1 more
TL;DR: It is observed that the Modified Delta method can advantageously be applied on the flight data of a tactical missile to estimate aerodynamic parameters, and the robustness of the both ML and Delta as the Modified delta methods is checked.
Aerodynamic Characterization of HANSA-3 aircraft using Equation Error, Maximum Likelihood and Filter Error Methods
TL;DR: In this article, the authors present issues related to the application of FEM with Gauss Newton (GN) and Levenberg-Marquardt (LM) optimization in estimating aerodynamic parameters from in-house generated flight data.

Estimation of Drag Coefficient from Radar-tracked Flight Data of a Cargo Shell
TL;DR: In this article, two schemes to extract drag coefficient (C) by processing the radar-tracked trajectories of artillery shell in motion, have been proposed, which are applied on the radartracked trajectory data of an artillery shell to estimate the C, which is strong function of Mach number.
