MSI was contracted by a major aerospace equipment supplier/manufacturer to design and prototype an FAA-approved vacuum generator for use on commercial aircraft.  The design would be subject to strict FAA requirements and RTCA environmental conditions/test procedures for airborne equipment.  At the customer's request, MSI studied the failure modes of the competitors' products.  In collaboration with the customer, a low pressure ratio single-stage centrifugal blower design was selected with a high-speed electric motor drive.  The design requirements included strict size and weight restrictions as well as aggressive duty cycle and life requirements.

As part of the development process, MSI used many of the analysis tools in its toolbox, icluding:
