grad applications are due in the range of dec1 to jan15. i think i took my GRE the september before that december.

and the (general) GRE is obscenely easy for undergrad engineers that speak native english. don't stress it. unless you do terrible, it won't hurt you. it can't even help you since engineers are expected to be at almost 800 on math.

>>2184464
go to college? but seriously, do this: sign on for some hard science or engineering major that you think you might be interested in. don't go in undeclared, just pick something. don't stress over the choice, it doesn't really matter, cause your first year will be the same in practically any major.

then, this is the important part: watch for emails/posters about upcoming research presentations, both by seniors in that department and by visiting researchers giving lectures. go to every single one that you can. your mind will be blown, and you'll say "wow, i want to be that smart", and you'll know what field you want to go into.

(caveat: as a guy with an MS and midway through my phd, i'm very biased here.) If you really really really exceed in your BS program, you can get some pretty nice jobs. I know people that ended up at every major aerospace company. You're never going to start very far above the bottom, but some at least ended up with remotely interesting work. the majority of people i did bs with (a bit above mid-tier state school) ended up with jobs i'd consider boring. working with cad models, boring structural analysis.

but if you're black or female, you can get a job at mission control at nasa.

and no, i never had any pure chemistry courses beyond my freshman chem class. you will learn heat transfer and fluid mechanics (things that stump chem undergrads), and propulsion at a ugrad level has a tiny bit of chemistry, but no. like many things, the basics will get you through BS.

and shit yeah it's fun and satisfying. good aerospace engineers need to know physics as well as physicists, math as well as mathematicians, computer science as well as computer scientists, and still have raw intuition and creativity in problem solving. it's a beautiful field.

Yeah, I'm an Amerifag, and I don't know how funding works elsewhere. But basically, every place I was in for grad school, offered full tuition support, health insurance, and a living stipend in the neighborhood of $1600-$2500/month depending on where in the country it was. so not making a lot of money, but definitely not spending anything on tuition.

very similar. many universities have combined aero/mech engineering departments.

from what i've seen, they tend to take slightly different approaches in teaching the material, but the fundamentals are the same. i'd say maybe in aero programs you tend to get some cursory orbital mechanics courses you don't have in mechanical, and in mechanical you might have a bit more on the thermodynamics side.

I'm not the OP, but your question seems curious. Regardless of the problem, most CFD (and FEM for that matter) solve the governing equations in essentially the same way. The computations, regardless of the problem at hand, are essentially the same. ANSYS CFX Solver descretizes the unsteady compressible Navier-Stokes equations in their conservative form, and solves them through an iterative Incomplete Lower Upper Factorization technique until some residuals or iterations criterion is reached. As such, I'm not sure what you mean by "most computationally intensive".

I'd recommend looking at solver theory documentation; they should explain the approach for each different solver, and are readily available online.

In case you're interested, the reason why they plan to study high-angle of attack on wind turbine blades is that they're looking at the small scale; 1 kW or so units. Very large, megawatt turbines obviously have variable pitch, but it's not just a good return on investment on small blades, and so you've got to generate a decent initial torque off of essentially a blunt face or whatever.

The goal of these guys, and their private friends (including the province's largest electricity distributer and its largest electricity producer) is to build a distributed grid off of these things.

Thanks for your response.

Looks like I'll be reading my vector calculus book over the break.

It's my understanding that most simulations are written in C++ but I have a decent amount of experience in MATLAB. From a non-research standpoint is MATLAB adequate for simulations where a very high degree of accuracy is unnecessary? I ask because I don't know how much original code development is required for a typical aerospace engineer. I am a much better programmer in MATLAB than C++ and would prefer to use MATLAB for programming if possible.

Also, I recently finished a quantum mechanics class for my physics minor. Does QM come into play in your simulations? (I would think in gas dynamics). Thanks very much for your time.

matlab does not affect your accuracy. it affects the time it'll take to achieve desired accuracy.

can you explain how to calculate the Delta V required for the Space Shuttle to decrease its altitude to 60 miles if it’s orbiting with an apogee of 236 miles and a perigee of 215 miles above the surface of Earth?

What is the difference between a physicist, an engineer, and a mathematician?

If a physicist walks into a room and sees a fire in the middle and a bucket of water in the corner, he takes the bucket of water and pours it eloquently around the fire and lets the fire put itself out.

If a mathematician walks into a room and sees a fire in the middle and a bucket of water in the corner, he convinces himself there is a solution and leaves.

If an engineer walks into a room and sees a fire in the middle and a bucket of water in the corner, he proclaims the fire is "fabulous". He proceeds to call other engineers and they pour the water all over themselves while fucking eachother in the ass while they dance around the fire.

sorry, just woke up to find this clusterfuck of pathetic kids with no degree in anything that think it's funny to spam engineer threads.

to answer the question, it's really just psychological. so many people i graduated BS with said "oh i'll go work for a few years and then go back and get a masters" and they almost never do. maybe 1 in 20 have, and it's because their company paid them to do it.

it's so hard for people to go back to school, both intellectually and socially. imagine going off to work for a few years, getting paid a good wage, and then signing on for 2+ years of getting paid practically minimum wage. even more, consider if you got married, had kids... real life gets in the way. i know so many people that said they'll go back for an MS/MEng, and they just never do.

>I don't really have any specific questions - mind telling me a little about it?
Well, pretty standard engineering first year. After that, (besides the obvious "chemistry") you're looking at coursework in fluid mechanics, heat transfer, general transport-type problems... I think there's a general trend for cheme's of late to start crossing over with bio-engineering type stuff. if you're interested in both biology/genetics and engineering, there's a lot of opportunities.

>The thing that sounds awful about it is the supposed business side of it. I hate business/economics. Is business/economics much of a part in aerospace?
I don't know of any business courses in chemE programs. certainly weren't any in aerospace. i mean, obviously you're going to have to deal with a business world at some point.

>Finally, why is aerospace engineering the king of all academic disciplines?
i think i already said. take computational fluid dynamics for example. (aside, chemE's are also interested in this field, especially in the combustion area.) in this field, we deal with the navier stokes equations. these partial differential equations are such a monumental challenge that their existence/uniqueness constitutes a millenium prize. pure mathematicians make no headway in this area. but to do CFD, we need a core fundamental understanding of all the mathematics buried in NS. then we need to understand numerical methods well enough to discretize these equations and then solve the arising systems. we need to know software engineering to write and maintain very large and fast programs that run on the most expensive supercomputers in the world in order to solve the problem at hand. but most importantly, we have to be engineers, and we have to know if what we're solving is actually what we want to solve, and how to apply it to complex physical systems.

I've never been at a school with an "engineering physics" degree, but looking at their website, that looks like a very neat program.

It looks like it must be a very broad (maybe a bit too broad) curriculum. but really, aerospace is extremely multidisciplinary. so my only concern would be wondering if such a broad-sounding degree would hurt in getting jobs at graduation, but it looks like they address that with the "aerospace systems design option."

looks like a pretty ideal undergrad program for someone going into grad school.

i say go for it. spend a lot of time in your first year learning more about what the specific disciplines are actually like. you're going to be taking basically the same classes anyway, and changing major won't set you back at all.
