EHD

ElectroHydroDynamics (EHD)

The EHD’s Quad Chart provides an overview of the study’s technical scope.

In space, it’s hard to keep your cool—especially if you’re a high-powered electronic device. Much of the electronic hardware found in modern satellites and space vehicles generates considerable heat. If not adequately removed, that heat can impair the performance of these devices or even cause them to fail.

For many years, NASA has been in search of a new way to deal with that heat to improve the performance and reliability of electronics in its satellites, planetary robots, and manned platforms, including the International Space Station. As with all space hardware, the solution should use little electric power, be lightweight, and have few moving parts, which could create noise and vibrations.

*Update: EHD project completes Preliminary Design Review

The EHD team presented the EHD Test Chamber breadboard and EHD System breadboard test results along with the required documents and drawings to a PDR Review Board and successfully completed the project Preliminary Design Review (PDR) milestone on May 27, 2020. The EHD Test Chamber PDR breadboard is being developed by Goddard Space Flight Center (GSFC) and was integrated into the EHD System PDR breadboard being developed by ZIN Technologies, Inc. The EHD integrated system level breadboard testing was conducted from January 2020 through March 2020 to gather data to prepare for the Preliminary Design Review.

The ElectroHydroDynamic (EHD) fluids experiment participated in flight week in Orlando Florida on the Zero-g reduced gravity aircraft. The Zero-g flight week operations were conducted on November 18-22, 2019. The EHD experiment reduced gravity rig operated and gathered data on 120 flight parabolas during the week. The EHD science team will analyze the data starting this week. The EHD project will use the reduced gravity flight data to further refine the breadboard design in preparation for the Preliminary Design Review (PDR).
