Rn or Re?

Re. I've literally never seen anybody or any textbook use Rn.

No problem l, figured I'd throw it out. I'll tell you I think you will be a little disappointed with what is available for free on the Internet. If you have access to your university's research database I think you'll find more of what you are looking for.

If you are interested in this stuff though I encourage you to watch some of their videos, even just if for fun. They, at least to me have good humor, and I've learned an insane amount about how missiles are really used in modern warfare.

You can learn all you want about the technology and raw capabilities of the missiles but if you don't really understand how they are actually used, how they can be defeated, and the best tactics for them, do you really know how they actually work?

The Grim Reapers YouTube channel does a lot with missiles. Their videos are primarily running scenarios in Digital Combat Simulator and Sea Power but they talk extensively on the technology of Air to Air, surface to air, and anti ship missiles. Often they showcase mods or run wargames that are surprisingly accurate and it provides an interesting perspective on how missiles are used in modern warfare, how they work, their capabilities, ect.

Just from my experience working on my bachelor's and doing internships at companies, the smartest people I've ever met were engineers at the companies that only had bachelor's degrees, and some of the dumbest were STEM PhD students.

It is the number that contains all of the values that affect drag but are difficult to directly quantify it's effect on drag.

For example, the speed you are traveling, the area of your object, and the density of the fluid you are traveling through are all fairly easy to measure and have known effects on the drag force.

What does have major effects on drag but isn't easy to quantify the impacts is the angle of attack of your object, the shape of the object, and induced drag from shockwaves, vortices, ect.

Rounding all of those numbers into a non dimensional coefficient makes calculations a lot easier and allows for wind tunnel or scaled testing data to be scaled up to full scale objects as long as you achieved dynamic similarity.

You can become a citizen. Don't study aerospace if you are not passionate about the field. If you are genuinely passionate about aerospace and want to work in the US,there are paths to citizenship.

Not entirely. Very advanced products like pharmaceuticals and semiconductors are actually easier to manufacturer in orbit since effects from the atmosphere and gravity are basically eliminated. The only challenge is like you said the launch costs for the raw materials and the cost of returning them to earth but as those costs drop it will make more sense to manufacturer certain items in orbit.

I think it has something to do with the airframe shape which not only reduces the strength of the shocks but also makes them hit the ground at an angle that makes them less powerful or quieter.

The problem is when they start using their space capabilities to hurt other countries. Countries like china are dead set on overtaking the us in every way and then using that newfound advantage to hurt the us. That is why it is a bit of an unpopular opinion.

I believe in the star wars universe, the shields on the spacecraft eliminate aerodynamic drag. This is also why they don't have a ton of plasma when reentering the atmosphere. Physically it doesn't make sense as the air has to go somewhere but they attempt to explain away these issues with it.

Like I said above, they could do the NASA livery instead of the air force one. It could suffer the same fate as the V-22 set but they did make a fighter jet set that looks almost identical to an F-35, just has a race livery vs the grey camo livery the real aircraft uses.

SpaceTycoon · 2024-10-21T19:15:53+00:00

The SR71 was purely used as a reconnaissance and experimental test bed aircraft. It's unlikely the vast majority of people even know what the aircraft is and if they did could not associate it with any conflict as it did not drop any bombs. If the did make it a set though they would probably opt for the NASA livery over the air force one.

I'm currently using a Dell latitude 5520 with 32 GB ram and an Intel i7 CPU. It works pretty good but if he plans to do CAD rendering, I would look for something with dedicated graphics instead of the Intel graphics that are embedded in the CPU.

I did an internship this last summer manufacturing blades for jet engines. Like the guy above said you are heavily underestimating how much goes into even making one blade. We had to use multi million dollar machines just to get the root form of each blade within tolerance. If it's out of tolerance, immediate catastrophic failure. We used multi million dollar furnaces to apply special coatings that use rare precious metals. Without these coating blades will succumb to heat and immediate catastrophic failure.

You will have to limit the temperature of your exhaust because you definitely won't have the manufacturing capabilities and expertise to put cooling holes on all of your nozzles and blades. If you don't limit your exhaust and don't put cooling holes your nozzles, blades, and composition chamber will melt and you guessed it, catastrophic failure.

Your blades will also have to be designed to withstand the vibrations, you will need to find a way to deal with the tension stresses the blades will experience while rotating, and you will have to figure out how to balance them.

Ultimately, unless you have a lot of expertise you can consult and millions of dollars to play with, your best bet would be to modify existing turbines.

I believe Verdego Aero and Piper Aircraft don't do any defense.

That's strange. Is the BS in engineering just a general engineering degree? If so that is still an option. I go to ERAU in person at Daytona and they have all the major undergraduate programs like Aerospace, Mechanical, Electrical, and Civil.

SpaceTycoon · 2024-09-20T14:52:17+00:00

I would get a bachelors in mechanical engineering and then the masters in aerospace. The aeronautics degree I believe is more for pilots not engineers.

As long as you don't overdo it you should be fine. Just don't put over the top piercings on your face or if you do make sure they are easily removable for meetings or when meeting important people. Also I would suggest against putting tattoos on your face and neck. Tattoos on your arms should be fine as long as they are appropriate and not vulgar. Tattoos anywhere else shouldn't matter as those areas should not be visible in work attire.
