Latest Patents

Ellerby holds a patent for a Woven Thermal Protection System. This thermal protection system (TPS) is designed for space vehicles that may experience partial or full ablation when subjected to extreme heating during entry into a planetary atmosphere. The first layer of the TPS includes materials such as carbon, phenolic, silica, alumina, and other oxides, combined with low thermal conductivity fibers and yarns. This layer is designed to be recession-resistant and has reduced porosity. The second layer serves as a thermal insulator, featuring a smaller fiber fraction, reduced thermal conductivity, and reduced density. The system evaluates various environmental parameters to ensure the ablator can withstand the conditions encountered during a mission.
