111214 - The exam tomorrow will be open notes, no computers or cell phones, bring a calculator. The exam will be comprehensive - anything covered in lecture is "fair game", so you should check out the lecture notes, solutions to problems and exams such as those posted below, and especially samples worked in class. I strongly advise you to write up a brief reference of all of the most popular equations and so forth so you don't spend the whole exam leafing through the thousand or so slides I showed this term. As part of your studying, you should also take a look at a couple of illustrative problems [problem - solution; problem - solution; problem - solution; ] and this example of a previous final exam.
111201 - All of the lecture slides are now posted here, along with the communications link budget spreadsheet (see the splash page for lecture #22). Major Breaking News: By request (as of this afternoon) of our DARPA sponsor for Exo-SPHERES, we are flipping the schedule for undergraduate Systems Definition Reviews: Exo-SPHERES will go on Tuesday, 12/6, and Space Servicing will go on Thursday, 12/8. (being responsive to the desires of your sponsors is another important lesson about aerospace engineering, as is being maximally flexible to schedule changes.) The Exo-SPHERES team should plan on one hour for your SDR, as the DARPA visitor wants to brief you on how this program fits into the DARPA research agenda.
Also, to help with your preparation for SDR next week, I have created groups for Exo-SPHERES and Space Servicing on the Blackboard site. This will give you a good place to exchange information via discussion boards, an area for sharing files, and the ability to easily send e-mail to team members, or to the entire team at once. I strongly suggest you use these group areas - it really will make your preparation time more efficient.
111129 - I'll get caught up in posting all the lectures shortly, but until then, here's the midterm exam with solutions [PDF: 217 kB; 8 pgs.]
111012 - Because of family obligations, I've had to reschedule my make-up lecture on Wednesday to 1:15-2:30 pm - sorry about the late notice.
111010 - Homework errata: on the homework for Lecture 06, problem (5) should refer to how the answer to (4) changes rather than (3). On the Lecture 08 homework, the payload for the Falcon 1e is 800 kg, which will change the answers to everything except #4. Sorry about that...
Because of these typos and multiple requests from 483 students with a lot of assignments due this week, I've changed the due date for this set of problems to Thursday, 10/13. Please be advised that I will NOT be changing the due date for the next problems (Thursday 10/20) as that's already the last date for those assignments without moving the exam again, which I DON'T want to do. You already have the assignment for Lecture 05, and I'll start posting the rest of them tonight so you have as much time as possible.
111003 - My apologies, I encountered the "perfect storm" of two reports, three proposals, four meetings, and three papers all falling due in the last two weeks of September, and ENAE 483/788D has suffered for it. With some (hopefully) minor rescheduling, we should be able to get caught up in the next couple of weeks. Obviously, there won't be any homework due tomorrow; it will be due a week from tomorrow. To make sure we have time to cover the necessary material, I'm moving the midterm exam back by a week. As always, the schedule is subject to change, but this is what it currently looks like.
110914 - Problem Set 03 correction: For Question 10, solve for the initial velocities assuming you're going to reach (0,0,0) a QUARTER of an orbital period later, not a full orbital period. (This should not take you long to do, but due to the short time remaining before tomorrow's due date, I won't take off if you don't have a valid solution to Question 10.)
110913 - There was an error in the problem set for Lecture 02. Please re-download for the correction.
