2. Objectives
Design, Build, And Test A Vibration Suppression System To Counteract Launch Vehicle Vibrations
Measure The Vibration Environment Inside The Terrier-Orion Rocket
Will 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

3. Review Of Last Year’s Launch Data

4. Review Of Last Year’s Launch Data
1st phase boost
2nd phase boost
Chute deploy
Z High range acceleration
Anomoly?
Design problem is to reduce these spikes on both graphs
