Radian One Sled / Vehicle ​ Aerodynamic & Structural Loads Analysis and Design Improvement​

The goal of this project involved figuring out a way to support the fully fueled 2.9 million pound Radian One vehicle during its ground sled run, when its wings carry very cold liquid oxygen and experience high rolling loads that could otherwise drive wing structural weight beyond mission limits. The project focused on a wing support system intended to reduce overall flight vehicle weight by carrying wing loads on the sled while still allowing enough airflow beneath the wings for normal takeoff. The concept evaluation considered alternative support approaches and their potential effect on dry weight, operability, wing aerodynamic performance, drag, and the risk of choked flow during separation conditions. A subscale model of the support system was built to enable wind tunnel testing and structural analysis.
