Venus Lander Experiment Vessel, Phase II

Completed Technology Project

Project Introduction

Venus Lander Experiment Vessel, Phase II
Ceramic Composites Inc. (CCI) of Millersville, MD in association with Swales Aerospace of Beltsville, MD have evaluated an innovative approach for the design of a Venus probe to maximize the payload volume and mass, while increasing probe lifetime. CCI and Swales have evaluated state-of-the-art materials and concepts to create a combination of thermal management approaches which maximizes value to NASA such as: 1) augmentation of the passive insulation with phase change materials (PCM) and two-phase evaporation cooling to maximize thermal protection at minimal volume and mass, 2) providing system corrosion protection through reverse flow gas balance to prolong vessel, sensor and window life, and 3) replacement of the titanium pressure vessel with a polymer matrix composite to reduce vessel mass and increase payload mass. The analyses conducted in Phase I indicate that the baseline concept will provide a lifetime of approximately 35 earth hours (while also managing a continuous 150W load from the scientific equipment) with a 100kg mass savings compared to a system employing the same thermal management system with a titanium pressure vessel. The Phase II effort will focus on refining the concept; designing, manufacturing, and evaluating a subscale prototype. More »
