3. Project Background
Use of Electro-Mechanical Actuators (EMA) in place of hydraulic actuators in aircraft applications has received significant attention in recent years due to their lack of supporting hardware, thereby reducing mass, volume, and maintenance.
Benefit is not without risk.
Failure modes associated with current EMAs can often occur without sufficient notice.
To be widely-utilized fault detection and failure prediction methodologies must be an integral part of the Health & Usage Monitoring System (HUMS).
State-of-health prediction in engineering systems is a rapidly evolving field that has a strong application to flight actuation.
Moog controller and LVDT that has been offered for donation to be installed and commissioned at RIT for future flight actuator HUMS research projects.

6. Group Behavioral Norms
All Group Members are expected to be respectful, honest, productive, responsible, accountable, helpful, and on time.
To ensure a balanced distribution of work, a weekly discussion will be held to inform group members of other responsibilities outside of MSD.
Individual's strengths are to be evaluated and discussed among the group.
Interaction with Dr. Kolodziej will be mainly through our weekly meeting and updates.
Inter-group communication will consist of group meetings, updates, and phone conversations.
Decisions will be made only after receiving consensus of the group.
It is expected that all group members will complete tasks on time and to the best of their ability.
Each group member has agreed to manage conflict within the group by being open to the opinions and ideas of their fellow group-mates.
