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)

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

School of Aerospace Systems

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 MinorsEach 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 & PropulsionSolids & 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

• 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)

Jet Noise Research Facility

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

• 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.

• 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 Problems:

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!

• ultrasonic • acoustic emission• eddy current• magnetic• thermography• thermo-electric• radiography (X-ray)• liquid penetrant, etc.
