Intake/Exhaust Max 1/3 Spectra

Design project partner Shane Severn welding an elbow on exhaust
resonator.
The same snowmobile was used for back-to-back
testing to determine the effectiveness of the "overkill'
air intake and muffler. The tests revealed that they
did decrease generated sound pressure levels of the
snowmobile.
Given the noise-reduction possible from implementing
an "overkill" air intake and muffler, the design team
determined that ¼ wave resonators would be a
feasible solution to limited design space. The team
has prototyped an air intake resonator, and is working
on completion of the exhaust resonator. Although
competition was rapidly approaching when this article
was written, the team is diligently working to ensure

project deadlines are met.
The team would like to thank Dr. Jason Blough and Dr. Scott Miers,
both of the MTU Mechanical Engineering Department, for their technical
support and advice.
This article was written for MOMENTUM by Mark Brouwer, who is in his
third year (captain last year) on the Michigan Tech Clean Snowmobile
team. This year, his senior design project for the team is noise attenuation,
and his partner in the project is Shane Severn. Brouwer expects to graduate
this spring with a bachelor's degree in mechanical engineering and begin
working for Milwaukee Tool Corp. in May.

A 2018 COLLEGIATE DESIGN COMPETITION
(CDS) PLAN FOR SUCCESS!!!
Advice and reminders for a successful 2018 CDS season:
1) Read the rules! Read the rules and re-read the rules
(this is part of the planning process).
2) Arrive prepared and ready to compete.
3) Have all your paperwork completed: registration fast
track form, technical inspection sheets, etc.
4) Ask questions beforehand; there are avenues for this
all year long.

5) Follow all the social media sites to keep abreast of
changes/updates:
facebook.com/SAEAeroDesign
facebook.com/FormulaSAE
facebook.com/BajaSAE
6) Attend all team meetings during the event. Teams
must/should/are required to attend "mandatory team

8 March 2018

meetings." These meetings are for the teams' benefit.
They give all the vital information needed for the next
day's activities. Teams not attending are severely
handicapped and will not be aware of changes and/or
adjustments to the schedule.
If you want to be successful, in any part of your life...
PLAN.
