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
