Programs of Study

The Aerospace Engineering offers three graduate programs of study with the following degree options:

The combined Bachelor of Science (B.S.)/Master of Science Program leading to the B.S. and M.S. degrees (Thesis or Non-thesis option).
The Master of Science (M.S.) program leading to the M.S. degree (Thesis or Non-thesis option).
The Doctor of Philosophy (Ph.D.) program leading to the Ph.D. degree.

Admission Requirements

For the M.S. program, applicants should have a B.S. in aerospace engineering or in a related field (i.e., other engineering disciplines, physics, mathematics, etc.). The requirements are the same for admission into the thesis and non-thesis options of the M.S. program. At the time of application to the master’s program, the student must specify his/her thesis option (thesis or non-thesis).

For the combined B.S./M.S. program, students must be currently enrolled as WPI undergraduates, or have graduated within the last five years from WPI, in aerospace engineering or in a related engineering field. When applying to the B.S./M.S. program, students must specify their intention to pursue either the thesis or non-thesis M.S. option.

For the Ph.D. program, a B.S. or M.S. degree in aerospace engineering or in a related field (i.e., other engineering disciplines, physics, mathematics, etc.) is required. The Aerospace Engineering Department reserves its financial aid for graduate students in the Ph.D. program or in the thesis option of the M.S. program.

Degree Requirements

The AE degrees are based on coursework and research. Courses are distributed in five curricular areas of study: Fluid Dynamics; Propulsion and Energy; Flight Dynamics and Controls; Materials and Structures; General Aerospace Engineering Topics.
