Abstract
As outlined in the original SBIR topic solicitation, the Marine Corps Expeditionary Fighting Vehicle (EFV) experiences excessive air handling unit noise and the cooling fan does not meet the established operational. A noise reduction of 35dB was demonstrated during Phase I. This Phase II project proposes to complete the Phase I design and deliver a tested prototype fan retrofit kit. The retrofit kit provides a low-risk and timely approach to overcoming fan noise issues during EFV EMD. Major fan system components, such as the driver, shaft/bearing system, fan casing, and fan system-to-vehicle interfaces, are not modified or replaced. Key retrofit kit components include a new low-noise fan rotor and a modified exit element. The Phase II effort includes optimizing the fan flow path design, performing aero-acoustics and mechanical prototype testing, optimizing the design based on the experimental results, and testing a redesigned prototype per Air Movement and Controls Association (AMCA) standards. The Phase II option includes final kit assembly, demonstrating EFV installation, and preparing an assembly and operations manual. MSI is well-positioned to manufacture and support EFV fan retrofit kit commercialization as part of its existing machinery products business unit or is available to collaborate with the current fan manufacturer.
