Behavior and Optimization of Hypersonic Inflatable Atmospheric Decelerator Devices for Spacecraft Re-Entry University of Maine/NASA Langley Research Center, Human Exploration & Operations Mission Directorate, Space Technology Mission Directorate

Hypersonic Inflatable Aerodynamic Decelerators or HIADs are one of the key technologies supported by the NASA Game Changing Development Program to mature innovative, high-impact new approaches to meet future space mission objectives and provide solutions to national needs. The purpose of this research project is to advance the basic understanding of the load-deformation behavior of HIADs. HIADs show great promise for use in space mission applications. They permit the landing of larger payloads due to their large frontal area relative to their stowed volume and total weight, and are also ideal for thin atmospheres. A Hypersonic Inflatable Aerodynamic Decelerator is a nose-cone-mounted inflatable structure consisting of multiple, concentric, nitrogenfilled tori that is designed to decelerate and protect spacecraft during atmospheric re-entry. A tension-torsion machine was purchased for this project. The goal of the tensiontorsion testing is to quantify the mechanical properties of the HIAD shell consisting of Technora braided fabric and a urethane bladder. These properties can then be used to generate input for FE models of inflatable structures.
