Task 3.6.1: A New Titan Chamber for Advancing Technology
Project Summary
The objective of this project is to develop a cryogenic chamber capable of simulating Titan’s lake conditions (1.5 bar N2 atmosphere, liquid mixtures of methane-ethane-propane in variable concentrations), and provide an experimental volume of 10 L. The purpose of this facility is to provide an environment for testing components and small instruments. Such a facility currently does not exist but is needed for achieving Technology Readiness Levels of 5/6. It will also be available to the community for scientific investigations such as measuring the equilibrium composition of lakes under realistic conditions, and exchanges between lakes and atmosphere.
Project Progress
This year, we continued the development of the Titan Chamber and conducted initial tests. The development tasks involved: – Finalizing machining of parts and tubing, and setting up connections to the vent line and the gas handling systems (both newly built). – Installing the inner pressure vessel and all inlets/outlets for electrical and gas/liquid connections. – Installing an automated gate valve to protect the turbopump in case of failure of the inner vessel (safety requirement) – Installing temperature sensors and heaters on the system. – Developed a LabView code to operate and monitor the chamber.
The initial tests conducted encompassed basic high-vacuum testing and cooling/temperature control performance assessment. These tests revealed two issues with the system, namely the lack of performance of the pressure relief system and of the closed-cycle cryostat. Further design work and replacement parts have been purchased and will be implemented in the coming months.
