Objectives Design, Build, And Test A
Vibration Suppression System To Counteract Launch Vehicle Vibrations
Measure The Vibration Environment Inside The Terrier-Orion RocketWill Use Two Identical Vibration
Measurement Systems○ A Custom Built Passive Damping
System○ Rigidly Attached System
Compare The Designed Passive System Vs. The Rigidly Mounted Undamped System
