thanks for the help guys, ill look into those. i figured as well that the shape would play a significant part. unfortunately it is cheaper to buy more cement than to pay people to dig a bigger hole. (without looking at the numbers, of course)

First off, I'm an aerospace engineer so please excuse the general incompetence in all civil and concrete matters I would like to make a steel reinforced concrete anchor point to tie down an airplane. The force applied to the eye bolt tie down is 10,000 lbs at approximately a 30 degree angle...

a turbulent boundary layer is more robust (less likely to separate) than a laminar one. as such, F1 cars, airplanes, etc... use it to trip the BL to turbulent just before an area where the flow may otherwise separate. as mentioned above, the separation point is difficult to control, it is...

First might want to check the laws in your country. This becomes a guided missile, and the ATF take a special interest in things like that slowly rolling during flight might be an unachievable dream. you have to be extremely careful when attaching your fins, and slight misalignment will give...

and so is neglecting friction and aero drag in dynamics problems, but when you're a student you have to start somewhere. basically, I am assuming the OP is a student, since the question has that school-ness ring to it

because they are so stubborn and unreliable, no person would ever step into an airplane with a 2-stroke powerplant...lol

the above post is quite accurate, with the exception of the quantity. satellites almost always have 4 (the fourth being at a 45 to all the other planes for redundancy) basically if 1 wheel wore out (they spin quite fast continuously) the 4th wheel could tak up the slack using its momentum...

intro to flight by anderson is a great resource, used it through senior year in aerospace engineering. has basic aerodynamics, propulsion, structures, rockets, etc. helicopters, on the other hand, are slightly more complicated. the basic principles, structure, propulsion etc... are...

i'm not overly offended, for the majority i agree with you completely its just i don't think its correct to say that knowing a lot of different things is entirely bad. admittedly fresh out of school, i couldn't do all the aero design on the next fighter, or the structure of the whole...

to answer the OP, i work with a lot of ME's making UAV's for the military. I would say that you should have no problem getting a job at an aerospace company with a ME degree. when you have your technical electives, select ones that you think may pertain to aerospace, or better yet talk with...

in my car (lancer evo 8) the blow-by goes into the intake after the MAF. through the turbo, intercooler, throttle body, and the blow by is burnt in the engine. admittedly this coats the intercooler in oil - decreasing its efficiency, which can be solved with a catch can.

Broad? Yea, i could see how having a very broad education and being able to do a little of everything would be bad, and companies DEFINITELY would not want that. [sarcasm] but what would i know? i just have a bunch of knowledge in aerospace BS. where i graduated, California State...

yup. just for simple wedges and cones. however, lots of problems can be simplified to simple wedges and cones. depending on the OP's exact problem, a rocket maybe, you can find pressure, density, temp, speed behind the shock. its just missing the pretty CFD pictures...

the NACA 1135 report covers supersonic gas dynamics. there's a table on conical shock formation. essentially all you need to know is 2 of the three to find the third: cone half angle, shock angle, and mach number. the report also has it for oblique shocks. could probably do 90% if not all...

first off, the fan was a good idea. but total rubbish if you want any sort of useful results if you have access to a car, you have access to a wind tunnel with relatively uniform cross sectional flow properties. basically you're going to do the thing with your hand out the window, where the...
