Mechanical, Materials, and Aerospace Engineering
Students are introduced to the scope of the engineering profession in the first-semester course “Introduction to the Profession”, and to the ethical, economical, safety, environmental, and other responsibilities of being a professional engineer. Strong emphasis is placed on development of oral and written communication skills. Accompanying courses in mathematics and the basic sciences provide the foundation for later studies of engineering sciences relevant to the students’ major fields of study. These areas include: energy, structures, and motion for the ME major; materials, structure-property relations, materials processing, service behavior, and design for the MSE major; and structures and materials, propulsion, and aerodynamics for the AE major. Regardless of the students’ intended major, all MMAE students have a common curriculum for the first two semesters.
The second year emphasizes building a foundation for the eventual study of engineering design. The engineering sciences offer a rational approach to solving detailed problems encountered in major-specific courses, including the IPROs and capstone design courses of the third and fourth years.
In the third year, students begin the transition to professional practice and learn to develop sound engineering judgment by studying open-ended problems and realistic constraints. Students build further on the engineering sciences, and approximately one-third of major-specific coursework is devoted to the introduction of tangible engineering design. The student’s professional experience is developed by participation in a minimum of two Interprofessional Projects (IPROs) in the third and fourth years.
The process continues into the fourth year where the three programs culminate in senior-year projects. Mechanical engineering projects involve design of thermal and mechanical systems; materials science and engineering students develop new or optimized materials, processing routes, or selection schemes; and aerospace engineering students produce conceptual designs of aircraft and spacecraft missions.
The MMAE department considers the advising of students an important obligation. Each student must meet with a faculty adviser during the advising period each semester. Students must closely adhere to course prerequisites to maximize academic performance and satisfy requirements for ABET accreditation. Students’ academic advisers can be found on their MyIIT portal account.
Program requirements may not be waived, nor will substitutions be permitted, without the approval of the departmental undergraduate studies committee.
- Bachelor of Science in Aerospace Engineering
- Bachelor of Science in Materials Science and Engineering
- Bachelor of Science in Mechanical Engineering
The Department of Mechanical, Materials, and Aerospace Engineering also offers the following co-terminal degrees, which enables a student to simultaneously complete both an undergraduate and graduate degree in as few as five years:
- Bachelor of Science in Aerospace Engineering/Master of Engineering in Materials Science and Engineering
- Bachelor of Science in Aerospace Engineering/Master of Engineering in Mechanical and Aerospace Engineering
- Bachelor of Science in Mechanical Engineering/Master of Engineering in Materials Science and Engineering
- Bachelor of Science in Mechanical Engineering/Master of Engineering in Mechanical and Aerospace Engineering
These co-terminal degrees allow students to gain greater knowledge in specialized areas while, in most cases, completing a smaller number of credit hours with increased scheduling flexibility. For more information, please visit the Department of Mechanical, Materials, and Aerospace Engineering website (engineering.iit.edu/mmae).
Minors available to students who wish to broaden their knowledge can be found in the Minors section. In all programs, two of the required minor courses substitute for two free or technical electives. Minors other than those listed below may be undertaken with the approval of the student’s faculty adviser and the MMAE undergraduate studies committee. In the event that a required course for a minor is also required for the major, an approved substitution must be made. Application to take a minor is typically made in the student’s third or fourth semester. Minors require completion of additional courses.
Among the minors that are available to ME, MSE, and AE students are:
- Aerospace Engineering (for ME students only)
