Quiet Fan Technology for Deep Space - Year 2

Completed Technology Project

Project Introduction

In the first year of this IR&D funded project, NASA working with RotoSub, has adapted a crew quarters (CQ) type fan into a noise canceling quiet fan that uses magnets imbedded in a fan’s blades as noise canceling speakers. This fan provides reduced noise emissions of the first two major fan tones by 15-20 dB, providing an overall reduction of 6-7 dB, with minimal airflow loss. ISS has plans in the near term to replace the existing fans in each of the 4 CQs. Investing a second year of funding into this project will go toward the flight certification of this hardware, allowing for an in-space demonstration of this technology, which would help open the door for the integration of this technology into the Deep Space Gateway and Transport (DSG&T) and future exploration missions. This technology has the potential to reduce noise of other types of axial fans, making this technology feasible for use in payloads and other flight hardware applications. More »
