Get all the CAD knowledge you can. The biggest issue that I found after the people that had a classic Technical Drawing background started retiring, was the drop in the quality of CAD images. Too many engineers were thrown in to the duty of maintaining drawings without a lot of training in CAD and it shows. The cub engineers that are coming up the pipe seem to have been given a better foundation, but the work of the few experienced draftsman left in the business still stands out. Also,- and this is a slice of personal advise that you are free to ignore- don't rush into the design end right away; spend the first part of your career in an airworthiness/flightworthiness position. One it will give you a better nuts-and-bolts view of aviation, and second will give you something to fall back on when you burn out in design.

The days of blueprints in aerospace are long gone. CAD files are the rule now. I started in the industry in the days of drawing offices full of ernst young men in short-sleeve shirts and pocket protectors. To get a modification through was a two-week process. Now as soon as it's approved, a few minutes with a terminal and the changes are instantly all over the system. Money or not most current CAD files are propriorty. I doubt if you will get your hands on them.

The stuff will stick to ANYTHING. Anyway if you encapsulate it it won't matter. The cured material can be super hard (it's used for dental work too) IF you pick the right variety.

Look into some of the clear UV curable lacquers. I use them extensively at work and they cure in about five seconds flat under short UV. With a total seal you wouldn't need the oil.

Whatever helps you sleep at night. I suspect though that you are probably exposed to more gamma during the course of the day from incidental sources that you would be from your element collection.

Can you reference some of these reproducible, 'on demand' results?

I wouldn't worry too much about gamma from a small sample. Anyway even that attinuates very rapidly with distance.

A one-time pad is a random key used only once for only one message generally based on the Vigenere cipher. Do I need more text? No, I'm not really interested in trying to break it.

Lead? A sheet of paper will stop anything coming off a chunk of DU. If it's under oil and in a glass container you have nothing to worry about.

Depends on conditions like temp, humidity and the crystal structure of the metal what what trace contaminants are in your sample.

The stuff will oxidize on contact with air so mineral oil is probably the best choice. I wouldn't try to clean it as the oxidation layer can go quite deep. In fact the oxide will flake off by itself and the process will continue untill the sample is gone.

Generally there is a whack of caffeine in the patent meds. If you are sensitive to that it might be what's causing the problems.

If it's based on some sort of one time pad it's not breakable. If it's based on an algorithm you might not have given us enough ciphertext to derive a solution.

No, it would not be wrong to say that.

Let's try again Aqueous nuclear fuels offer a unique set of characteristics for homogeneous reactor nuclear applications. Their advantages include high nuclear stability and inherent safety, high power density, high burn-up, simple preparation and reprocessing, easy fuel handling, high neutron economy, and simple control system leading to simple mechanical designs. The major disadvantages are corrosion, limited uranium concentration, and radiation decomposition of water.

About the best site on the net is: http://www.se-technology.com/wig/index.php A lot of info on WIGs.

Trouble is that applications like that look good on paper but the market for them doesn't materialise. The Russians have been at the WIG game for decades and even under a command economy couldn't find much use for them. The big issue with heavy carriage is that there are few commodities that ship in bulk that are time sensitive enough to warrant the added expense of shipping them on a WIG craft over a regular boat.

Woops! Fixed

Aqueous Homogenous Reactors are what their name suggests; water in which soluble nuclear salts (usually uranium sulfate or uranium nitrate) have been dissolved in water. Thus the fuel is also the coolant and the moderator, thus the name "Homogenous" ('mixed together') The water can be either "Heavy Water" (water enriched in naturally occuring deuterium [the first isotope of hydrogen, with 1 proton & 1 neutron]; a deuteron occurs in 1 out of 6400 atoms of hydrogen.) or ordinary water, both which are very pure. A heavy water aquous homogenous reactor can achieve criticality (turn on) with ordinary, un-enriched uranium dissolved as uranium sulfate! Thus, no enrichment is needed for this reactor. They where sometimes also called "Water Boilers", as they seemed to be boiling their water, but the bubbles coming out are hydrogen and oxygen as the radiation, and especially the fission particles, rip apart (dissociate) the water into its constituent gases, were widely used as research reactors as they have very high neutron fluxes and their safety and ease of control (they were self-controlling!) were added pluses. Their most interesting feature to me is the Heavy Water versions have the lowest specific fuel requirements (least amount of nuclear fuel is required to start them). Even in ordinary water versions less than 1 pound (454 grams) of Plutonium-239 or Uranium-233 is needed for operation! Neutron economy in the heavy water versions is the highest of all reactors. Their self-controlling features and ability to handle very large increases in reactivity make them unique among reactors, and possibly the safest. Anyone for a science fair project? Via: Bruce N.

Here's the gen on building a tuned exhaust L = (850 (180 + N)/RPM)-P where L = length of pipe in inches N = degree before BDC exhaust valve opens P = distance from exhaust valve to manifold and RPM = desired RPM The diameter of the pipe needs to be calculated so that the volume of the exhaust pipe attached to each cylinder is twice the volume of each cylinder. The exact diameter of the pipe, incidentally, is not critical and should only be used as a guide in determining which standard sized pipe diameter should be used.

We can only hope....(but probably it's a crock)

WIG (Wing-In-Ground) effect planes are the best example around of a solution looking for a problem.

By nuking them! You can put a sample in a high neutron flux inside a nuclear reactor to produce any number of isotopes commercialy, or the beam from a particle accelerator to make in in small experimental amounts.

Well they all have to be moving in the same direction, for a start. Also in some way everything does have a magnetic component, it just needs to be teased out with something like NMR.

My father-in-law made a exhaust muffler once for a fixed powerplant, so I just asked him what exactly he had done. He made the thing out of cast iron, as weight wasn't an issue and the added mass of the material, he felt helped. The geometry was rather simple: A center 1.75in pipe perforated with 0.5in holes terminated at one end with a plug, inside a 4in sewer pipe with end caps. the small pipe passed through the end cap at one end, and an exit pipe was attached at the other end cap. The total length was 22in, because "that was what I had on hand."
