Tunable, Resettable, Printable, Impact Energy Absorbing Matrix

Active Technology Project

Project Introduction

Tunable, Resettable, Printable, Impact Energy Absorbing Matrix
Landing on a largely unknown planetary surface imposes risks to the structure of the lander. This effort seeks to reduce the risk of energy absorption in two ways. Primarily it provides a method of fully characterizing an energy absorbing material through analysis verified by testing. Secondly, since energy absorbing elements will likely need to be constrained geometrically (such as within a cartridge enclosure), this effort would provide the basis for a CAD model that could easily be changed late in the design process without having to change the supporting structure. The ability to custom 3D print energy absorbing materials/substructure would greatly support flexibility in future lander designs. This effort will begin with 2D and 3D printed plastic prototypes, followed by development of a 3D printed titanium prototype. Test results for the titanium prototypes are due by the end of the FY.
