VESSEL INSULATION ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an insulation assembly for use with cryogenic propellant vessels, and particularly, an insulation assembly that includes a micro-truss reinforced cryofoam.SOLUTION: A vessel 102 includes a vessel wall 104 and an insulation assembly coupled to the vessel wall. The insulation assembly includes a stochastic foam material and a microtruss structure encased within the foam material. The microtruss structure includes a plurality of truss members connected at a plurality of nodes. Each truss member is in contact with the foam material such that the microtruss structure provides a structural core for the foam material.SELECTED DRAWING: Figure 4
