A shape-stable structure that is configured to provide ablative cooling. The structure is used to form a component that includes shape-stable bulk structure and an ablative material. The bulk structure is infiltrated with the ablative material so that the ablative material is disposed in pathways defined by the bulk structure.

Shape-stable structures with ablative cooling

The present disclosure relates to an engineered, additively manufactured, microfluidic cellular structure formed from a plurality of cells, wherein the cells are each formed from a plurality of interconnected elements. The cells have voids and each cell is open at upper ends thereof. The cells each communicate at a point below its upper end with a common channel. The cells are each configured to accept a fluid and operate to channel the fluid into the common channel and to hold the fluid received therein for later selective withdrawal from the structure.

Systems and methods for reaction and transport engineering via cellular fluidics

A semi-passive cooling system for a component exposed to a fluid flow utilizes a hierarchical vasculature and a sacrificial transpirant to cool the component. The component includes a body that defines a transpirant reservoir and the hierarchical vasculature. The transpirant is configured to transition between a solid phase and a vapor phase over an operating temperature range of the component.

Semi-passive cooling using hierarchical vasculature

An ink, and products formed from the ink, formulated at least in part from ceramic particles. The ink is formulated so that it can be used in additive manufacturing processes to form three-dimensional printed bodies. The three-dimensional printed bodies can have graded density and can be infiltrated by an infiltration material.
