Principles of Community

The Virginia Tech Principles of Community will guide all our interactions together this semester; above all, this class should represent an environment in which everyone is treated with respect and encouraged to learn and grow. The VT Principles of Community are intended to increase access and inclusions and to create a community that nurtures learning and growth for all of its members; as such, they will guide our interactions this semester:

  • We affirm the inherent dignity and value of every person and strive to maintain a climate for work and learning based on mutual respect and understanding.
  • We affirm the right of each person to express thoughts and opinions freely. We encourage open expression within a climate of civility, sensitivity, and mutual respect.
  • We affirm the value of human diversity because it enriches our lives and the University. We acknowledge and respect our differences while affirming our common humanity.
  • We reject all forms of prejudice and discrimination, including those based on age, color, disability, gender, national origin, political affiliation, race, religion, sexual orientation, and veteran status. We take individual and collective responsibility for helping to eliminate bias and discrimination and for increasing our own understanding of these issues through education, training, and interaction with others.
  • We pledge our collective commitment to these principles in the spirit of the Virginia Tech motto of Ut Prosim (That I May Serve).

ABET 2000 Criteria

We will focus on presenting the course as well as structuring the homework problems, projects, and exams consistent with ABET 2000 criteria, which state that graduates in AOE must demonstrate:

(h) the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and social context.

(i) recognition of need and ability to engage in life-long learning.

(j) knowledge of contemporary issues.

(k) an ability to use techniques, skills, and tools in engineering practice.

 

Course Description

This course is an overview of aerospace engineering from a design perspective.   We will cover topics such as:  

    • introductory aerodynamics, lift, drag, and the standard atmosphere
    • aircraft performance, stability, and control
    • propulsion
    • structures
    • rocket and spacecraft trajectories and orbits

Prerequisite courses: ENGE 1114, Physics 2305.

Course Structure

A hybrid approach will be used for this course.  

Tuesday will be a traditional lecture.   Dr. Artis will use a Surface Book with partially-completed powerpoint slides.  During lecture, he will use these slides as a digital blackboard.   PDFs of the powerpoint files will be available prior to class so that you can make your own notes.   Homework assignments will also be announced on Tuesdays.   It is expected that you do the assigned reading, and begin working the homework assignment so that you can make the most of the recitations on Thursday.

Thursday will complete the lecture and include workout problems to demonstrate the lecture concepts.   It is important to come prepared and be ready to ask questions.   If there are no questions, quizzes may be used to asses level of understanding.

Learning Management System

All class materials (syllabus, calendar, homework assignments, lecture notes, and supplements), announcements, and grades will be distributed using the new Virginia Tech Learning Management System, http://www.canvas.vt.edu/.   Some resources to help you with Canvas:

Grading

Homework  30%
Exam 1 20%
Exam 2 20%
Book review 5%
Rocket project          5%

Attendance Policy

Attendance will not be taken, however, it is expected that you attend all lectures and recitations.    If you have planned absence, please let Dr. Artis know.

Laptop Policy

The use of laptops will not be permitted in class.   Laptop screens can be a major distraction to other students, especially if you are surfing the internet instead of paying attention.   Therefore technology is limited to tablets which lay flat on the table.   If your internet activities are a distraction to other students or the instructor, you will be asked to leave the classroom.

Homework Policy

Homework will be assigned on Tuesdays, and will be due at 11:59pm on the following Monday.   Your homework submission should be submitted in digital form (PDF preferred) to the course page on Canvas.   Your submission should include a title, your name, and email address.   All work should be shown, and it must be clearly written.   Where appropriate, all dimensional units should be included.   Illegible submissions will not be graded.   Late homework will not be accepted, except for extreme circumstances or documented illness.
