Non-Thesis & Thesis Options
• Most (but certainly not all) GE ACE students
choose the non-thesis option:
– Requires 2-credit “Final Project”
– Project supervised and approved by either
• AsE/EM faculty member(s) :
– Signed “final” project completion form (by 2 UC faculty members)
required to graduate, no defense
• or GE review board
Majors and Minors
Each major area has required classes for MS:
Dynamics & Control:
• Required: Modern Control and Analytical Dynamics
• Plus 2 3-credit graduate courses in Dynamics and Control area (some can be from other
Dept’s)
Fluids & Propulsion:
• Required (3 out of 4): Combustion, Advanced Propulsion, Compressible Flow and
Thermodynamics, and Viscous Flow and Heat Transfer
• Plus 1 3-credit graduate course in Fluids & Propulsion
Solids & Structures:
• Required: Elasticity
• Plus 3 3-credit graduate courses in Solids and Structures
Minor area:
 Usually another technical area in the Dept., but sometimes outside Dept. (permission
required), F&P MS majors can use F&P as minor
 Number of credits outside Dept. is limited (6 for MS, often waived by petition to 9)
PhD Program
• Automatic acceptance of our own MS students
• Requires 92 credits beyond BS degree:
– MS degree counts as 30 credits (30 course, 15 thesis)
– Dissertation is 30 credits, Dept. Seminar is 2
– Coursework beyond MS degree: 30 credits - C course
• Requires passing PhD Qualifying Exam:
– Written exam (8 hrs open book on major area & math)
plus oral presentation (summary of review of selected
papers plus questioning by area faculty)
– Maximum of two chances
– Time limit on passing – Two years from entrance to
PhD program
Current GEAE R&D at UC Aerospace Engineering Department

Jet Noise Research Facility
• Developed by Prof. Ephraim Gutmark and his students in
Aerospace Engineering with support from the GE
University Strategic Alliance (USA) program.
• Models the flow characteristics of modern turbofan engines.
• Used to validate and develop innovative concepts for reducing
noise from jet engines.
Features:
•Supersonic core flow, sonic fan flow
•Core flow temperature range: Ambient to 350°F
•Mass flow rate: Up to 8.5 lbs/sec
•Run times: Up to 20 minutes
•Rapid changes of nozzle geometry possible
•Unduplicated among university-based facilities
Nondestructive Evaluation (NDE)
Profs. Peter , Francesco Simonetti, & G. R. Liu, UC Aerospace Engr.
http://www.ase.uc.edu/~pnagy/NDE/
NDE technologies are required to safely exploit the full
service live of fracture critical components!
Inspection Problems:
• flaw detection and characterization
• residual stress assessment
• thermal and mechanical relaxation
• high- and low-cycle fatigue
• creep damage, plasticity
• corrosion, erosion
• hardening, inclusions, segregations
• adhesive and cohesive strength
• thermal barrier coatings, etc.
Inspection Methods:
Graduate Courses:
• AEEM-727 Nondestructive Testing
• AEEM-728 Introduction to Ultrasonics
• AEEM-729 Ultrasonic NDE
• AEEM-974 Electromagnetic NDE
• ultrasonic
• acoustic emission
• eddy current
• magnetic
• thermography
• thermo-electric
• radiography (X-ray)
