2. Admission Requirements • No prerequisite requirements for students with BS or higher in most engineering areas: • Aerospace or Aero/Astro • Mechanical • Engineering Mechanics or Engineering Science • Chemical • Civil (might require review of Dynamics) • Electrical (might require background courses depending on area)

3. Technical Specialization Areas • Three areas of specialization within Dept.: • Fluids & Propulsion: Combustion, propulsion systems, propulsion components, CFD, experimental fluids • Solids & Structures: Nondestructive evaluation (NDE), material behavior, finite element analysis • Dynamics & Control: Analytical dynamics, simulation of dynamics, control algorithm analysis and development, planning, diagnostics

4. School of Aerospace Systems • Aerospace Engineering and Engineering Mechanics • Project (Non-Thesis) Option • 10 semester hours transferred from GE for A & B GE-ACE courses. • 21 semester credits completed at UC consisting of • one full-time semester on-campus (15 semester credits) • one part-time semester • Course requirements will be: • 12 Major Credits 3 Minor Credits • 3 Tech Electives 2 Research (final project) • 1 Seminar • All Courses must be 6000+ or higher • All courses taken at UC must be program approved courses (see handbook for requirements) • Graduate Program Director • Dr. San-Mou Jeng – 556-3361, san-mou.jeng@uc.edu • Graduate Program Coordinator • Julie Muenchen – 556-0635, julie.muenchen@uc.edu • http://www.ceas.uc.edu/schools.html

5. 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

6. 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)

7. 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

8. Current GEAE R&D at UC Aerospace Engineering Department • GEAE/UC Aerospace Centers (Ohio Third Frontier) • (GEAE) to establish a GEAE research and development center and • (UC AsE) to establish UC Center for Intelligent Propulsion in Advanced Combustion, CMC, Component life and Thermal Management • Establishment of University of Cincinnati Research Center (UCRI) • GE University Strategic Alliance (USA) Program in: • Jet Noise Prediction & Reduction • Turbomachinery CFD Methods • Direct funding from GE to UC Aerospace Engineering Department (around $2M in 2010-2011 academic year)
