(including wash out analysis)

Controls and Loading Design ProcessMain goal is developing the process for analyzing weight

loading and stability capabilities.Using weights, coefficients of lift, distances, and equations

from individual groups to arrange the aircraft design for project requirements.

Develop Matlab coding and use ‘ball and stick’ moment and force approximations to conduct analysis.
