Once, a student had to attend lectures in materials science and TMM – doctor of technical Sciences, Professor Nikolay Vasilevicha Chepelskogo. The pair were hard. Techie who knows what is TMM (theory of machines and mechanisms), the student – There is My Grave.
From time to time, he had brought any piece of iron and told them about interesting stories. It is also worth noting that back in the early 90’s, we all for the most part, were impressed by “all foreign”, and his lectures, as far as I understand now were a vain attempt to cover our eyes to their imaginary superiority.
Now.
One day he brings some crap – like thing out of the gear case. Forces us to carefully consider this thing, and to Express its views on its design, quality and potential properties. We (as happened almost always) itch in its own way, something about the primitive type of construction, manufacturing techniques, inaccurate casting etc., etc. – engineering considerations.
Then Nikolai blue eye begins to describe this contraption in your own words. It turns out that this is, indeed, part of the aviation corps of the planetary gear unit. Also it is clear (and not to trust the Professor we have no reason to be) that a node with these parameters does not produce today no one in the world. Internal parts, it appears, is perfect from a technological point of view, inscribed in the body, and the weight of the unit, in the case of more high-quality treatment of the external body can be lowered by a few tenths of a percent, the processing parameters of the internal – sufficient and their improvement to changes in technical specifications. After that, Shepelsky with a triumphant appearance pulls similar foreign thing. Mirror gloss, anodized orange metal logo – charmed everyone. It was clear that the company A. then, with his characteristic aplomb, the Professor reports that this is similar to the case of the American unit. While not casting, and cutting, while the parameters of the gear placed inside in the order below, and the mass is several times larger than ours, with a kind of ugly. It was then that he taught all of us not to pay attention to what he called “a redundancy in the elaboration of unnecessary detail in the absence of engineering”. Simply Americans always compensate for the shortcomings of his own engineering education metal. Where they feel insecure – more metal and is already reliable. The modern CAD system is not changed, but only adjusted to this property.
He clearly allies about the story told:
… It was already near the end of the war. It so happened that the British gave the USSR the German manufacturing technology of the “jumping” of torpedoes. I passed, but my specialist sent after production has been established and is likely from what Stalin said to Churchill a number of products. It turned out that the Russians were able to make torpedoes almost ten times faster than the Britons. And here’s why. Based on German technology with all castings and forgings burrs were cleaned manually with a chisel and almost needle files. Man – hours for this operation required an awful lot. That saw a British engineer in the USSR could reduce them to any of mind: casting the excess metal was broken off with a chisel or a jackhammer, after which, if not prevented the Assembly is not processed even a rasp. The body is just welded on fin. It had no effect and did not worsen the characteristics of the product, and if it was, then a few tenths of a percent, and, given the fact that the torpedo is a one – time thing – the color lacquer Russian products was not provided. Especially British. And again this short story of Chepelskogo demonstrated properties of Russian/Soviet engineering.
Under the tables of the audience we had to be after Nikolai gave us to squeeze two PCBs, as we then called them chips. One was a palm, greenish, dotted with many unreal tracks. It sported a “Made in USA” and “General Electric”, and the second is gray with Golden, equine species, the tokovodov. Turned out to be eventually as is always chepelskogo, Vice versa.
The first NATO military trash, burnt in case of the slightest overload. The second piece of our Soviet Commissar to withstand AMY’s and, unlike American women – double layer. It is more than all Chepelskogo virological the fact that “these assholes” is secure “nah***Chile logos all over the product”, and our – do not bother the product even mark, for that was no place, so gorgeous markings replaced the blue print on the surface, near the same print quality.
What is this? Today is the 21st century. The exam, when you first look at what is happening – kill basis – fundamental education for every citizen. But, is not so clear, I tell you. Engineering thinking to us organically, as well as the ingenuity with resourcefulness.
Not convinced that Russia is able to produce decent basketball shoes, but the fact that from any garage in the middle lane instead of a used six may travel, for example, the product number 6420 with Technical and Tactical Characteristics superior to those of the “hammer” is almost certain. Savvy orders, but to be ground – fire, no patience.
UPD From comments, but it’s interesting… it Turns out that the school has.
Syria. Our bombing. The guiding device is the equipment of the aircraft. Optical sensor plus GLONASS. The accuracy of the dumping of 1.5 – 3 meters, the reaction time is 0.3 seconds. The issue price per set – in the area of 125 thousand dead raccoons. After the equipment of the aircraft system, whatever that dump with the required accuracy. Although stocks from the warehouses, which will last for five years, though the sacks of potatoes, though the weights.
Whether the case of the United States. Exactly, I’ll tell you another thing. Each unguided bomb fitted with a set of rudder feedback. The issue price apiece – around $ 20 thousand.
