Background of Company:

For more than 60 years, Fleet Readiness Center East, at Marine Corps Air Station, Cherry Point, N.C., has played an integral role in our national defense. The facility's In-Service Support Center provides multi-disciplinary, engineering services in both design and maintenance. Our workforce has earned a reputation of excellence, providing worldwide support for Navy and Marine Corps aviation.

Fleet Readiness Center East has provided maintenance, repair, and overhaul support to virtually every weapons platform the Marine Corps has flown – from the inverted gull-winged F4U Corsair of World War II fame, to the Corps newest aircraft, the F-35B Lightning II. It is one of eight fleet readiness centers operated by the United States Navy. It is also the Department of Defense Vertical Lift Center of Excellence. FRC East has a workforce of about 3,800 civilian, military, and contractor personnel. It is North Carolina's largest industrial employer east of Interstate 95.

NAVAIR is an active participant in capstone projects for a variety of school and uses said projects as a means for recruiting high achieving engineers.

Project Background and Need:

The first semester is the design phase and the second semester is the implementation/build phase. The teams will meet weekly with their faculty mentor to discuss progress. Technical contacts are invited, at their option, to attend by phone, virtual meeting or in-person. Each semester, there are two design reviews and an end of semester exposition – attendance of these 3 events is mandatory to ensure awareness and agreement for project direction.

Problem Description/requirements (List of high-level functionality you expect to see in the end product):

The scope of this project is for the student team to study the design, functionally and performance of a Permanent Magnet Synchronous Motor (PMSM), develop a load model for that PMSM, and design a physical prototype of that load. This prototype load will be used as a test load to test a PMSM controller without the need of having a motor and a mechanical load attached to it; the test load will take their place when testing the controller.

Project Requirements:

• The sponsoring technical contacts will provide a three-phase motor controller that generates three-phase current at varying frequencies to the project team, as well as a compatible PMSM with a mechanical load. This should assist the project team in understanding the performance of the overall system and use the motor controller to demonstrate their test load prototype performance.

• The prototype test load’s electrical performance shall be equivalent to that of the provided PMSM under both of the following scenarios: with mechanical load attached and with no load attached.

• Additional specific project requirements or details may be communicated to the project team directly by FST sponsors.

Expected Deliverables/Results:

The team must deliver the following products:

• The developed model and/or simulation of the test load.

• Physical implementation and demonstration of the prototype test load.

• Full written report on the load model design, analysis and performance data.

Required Skills / Desired Competencies (in order of importance):

• Analog circuit analysis

• Power electronics

• Electromagnetism

• Electromechanical systems

• Matlab/simulink simulations

• Software modeling and simulation

Students working on this project must be US citizens
