Overview

The Kevin T. Crofton Department of Aerospace and Ocean Engineering offers a Bachelor of Science degree in aerospace and ocean engineering. Students may major in either aerospace engineering or ocean engineering. These majors share many course requirements, because the two curricula cover a broad range of common interests and offer a wide range of technical electives. Students may double major—aerospace with ocean engineering or ocean with aerospace engineering. The Department also offers a minor in naval engineering, which is open to non-AOE students.

The undergraduate programs' educational objectives are that graduates will combine their undergraduate education and post-graduation experience to:

• Be successful in entry-level professional positions or in graduate study in aerospace and ocean engineering.
• Apply the theoretical, experimental and computational fundamentals of science and engineering to professional practice, advanced study and continuing professional development.
• Apply their broad understanding of fluid dynamics, vehicle dynamics and control, propulsion and structures to design and synthesis of aerospace or ocean systems in a team environment.
• Communicate their work effectively to both experts in their field and non-technical individuals.

The department's curricula are vehicle oriented, with an emphasis on propulsion, aero/hydrodynamics, stability and control, vehicle performance, vehicle structures, and energy and the environment. A year-long capstone design experience in the senior year uses the group design process to both better simulate the way design is done in the real world and promote the benefits of collaborative learning.

AOE graduates have been highly successful in the aerospace and ocean fields. About 15% of our graduates continue their studies in graduate school, while most of the rest find excellent employment opportunities in the aerospace and related industries and in the shipbuilding, naval engineering, and ship design fields. Some also choose to go into related fields such as automotive engineering, structural engineering, environmental engineering, as well as into professions such as law or medicine.

AOE is home to a number of unique facilities, including Stability, Open-Jet, Boundary-Layer, Low Speed, Transonic, Supersonic, and Hypersonic Wind Tunnels; the Advanced Propulsion and Power Laboratory (APPL), Space@VT building, the Kentland Experimental Aerial Systems Laboratory (KEAS), the Hydro-Elasticity Laboratory, Hydrodynamics Laboratory, Marine Robotics Laboratory, and Newport News Shipbuilding (NNS) / Aerospace and Ocean Engineering (AOE) Teaching and Research Laboratory.

The department encourages students to seek internships and to participate in the Cooperative Education Program, which gives qualified students valuable industrial experience while working toward their engineering degrees. The department's required design courses often include multidisciplinary projects.

The Aerospace Engineering and Ocean Engineering programs are accredited by the Engineering Accreditation Commission of ABET, www.abet.org. The department also offers programs of study leading to M. Engr., M.S., and Ph.D. degrees.

AOE students must meet all Pathways requirements and only certain "free" electives and courses designated as "P/F Only" may be taken on a Pass/Fail basis. Lists of approved electives including technical, math, Liberal Education, and other electives are available on the department's web page: www.aoe.vt.edu/undergrad/undergrad-advising/index-undergrad-advising.html.

Degree Requirements

The graduation requirements in effect during the academic year of admission to Virginia Tech apply.
