NASA funded: The project has identified two PCM Hx concepts that have paths for possible infusion to future vehicles such as Orion. The project includes development and an eventual technology demonstration on the International Space Station (ISS). The first heat exchanger is wax-based and has reached a TRL of 4. The project will build a wax-based PCM Hx in partnership with UTC Aerospace for flight demonstration on ISS. Testing a wax-based PCM Hx in a relevant environment will allow an \"off the shelf\" option for future vehicles, such as Orion, that require long duration supplemental heat rejection.
","description":"The primary focus of the project is to provide future space vehicles a reliable form of long duration supplemental heat rejection (SHREDs). SHREDs allow a vehicle to reject waste energy when nominal means do not allow so. The project is investigating, through partnerships with UTC Aerospace and Mezzo Technologies, the use of wax and water based PCM Hx. The project will culminate with a technology demonstration on ISS.

However, the wax PCM did not meet its threshold value for the mass fraction Key Performance Parameter. The water PCM achieved TRL4 after completing testing in the lab. The PCM project extended the performance capability of heat sink thermal management technology for in-space applications. The project focused on establishing the capability of using a paraffin system which has system design and thermal transport benefits over existing systems being used on the International Space Station (ISS), A PCM was developed and successfully demonstrated on board the ISS in an experiment to prove out predicted microgravity operation and operational capability. The ISS flight experiment was designed to be a subscale demonstration of an anticipated Orion PCM heat sink system and was successfully tested from August 2016 through May 2017.","infoText":"Closed out","infoTextExtra":"","dateText":"June 2017"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"GCD","active":true,"description":"Solicit innovative ideas enabling new capabilities or radically altering current approaches to launch, build, and operate space systems.
