Incredible advice, thank you very much NobodySpecial and AlephZero, I will pursue the research project. Hopefully I encounters employers that share likewise ideas :)

I do believe my GPA is pretty competitive, but even though a minor sticks on your diploma for good, in your opinion it's still better to have actual research experience getting out of undergrad? What about if the research project doesn't have much to do with one's projected career path? For...

Hello! I will soon be starting my final semester in my undergrad career, studying Aerospace Engineering with a focus on air-breathing propulsion. I would highly like to pursue a career in the propulsion field (as well as find a place that will pay for masters), so I'm looking to make myself as...

Homework Statement http://img27.imageshack.us/img27/1695/asdfgv.th.png Homework Equations Your guess is as good as mine The Attempt at a Solution I have no idea how to even begin this problem. What equations are relevant?

Like you said, a turbine needs gas to be heated in order to provide power to the compressor. I am trying to find out an alternative that DOES NOT require gas, hence does not require a turbine. From my research, I have only found ducted fans that use fans. Would adding a compressor still...

Can you explain what the purpose of counteracting the compressor thrust is? Or is that just another way to saying that the turbine "uses" the thrust generated by the compressor?

But if the compression is powered by an outside source, then there is no need for a turbine. So only the compressor is in the nacelle, well a compressor and a fan (to draw more air in), both powered externally. Does the compressed air then turn into thrust?

Does an inlet really come into play at subsonic speeds, besides just providing air into the rest of the engine?

To minger, Enough thrust to lift a human vertically into the air.

Does an equation exist to determine how much thrust is produced from pressure? And does one exist to determine how much pressure is produced through each stage of a compression chamber? Also, is there a recommended book that perhaps goes into the details of propulsion via compression and not...

Wohoho! I totally see what you are talking about! They are indeed massive regardless

Well a ducted fan is precisely what I am trying to avoid, mostly because the amount of thrust needed would require a massive fan. What I am talking about, however, is a series of a compression rings. That is, can I achieve thrust simply by compressing and compressing air and then releasing it...

What if someone took a jet engine and took out the combustion and turbine mechanism. Then that person found an outside source to power the compression mechanism. Can the compression mechanism alone produce significant thrust? That is, with an outside power that does not add heat into the system...

So my answer will be in the form of "M" and "d"?

Homework Statement A cord is used to vertically lower an initially stationary block of mass M at a constant downward acceleration of g/4. When the block has fallen a distance d, find (a)the work done by the cord’s force on the block, (b) the work done by the gravitational force on the block...
