Present to the readers a model rocket class S1B (altitude) with a total impulse of engines to 5 N·s allowed A. Mityureva for a number of years show high sports results (1990— second place at the world Cup, 754 m; 1991— first place in the match USSR—USA, 860 m; 1992—second place at the world Cup, 787 m; 1993— first place on European championship, 1178 m). It should be noted that such good results have been achieved thanks to, among other things, and specially designed engines designed by A. Sparia.
WINNING “SKYSCRAPER”
Unbeatable the development of composite and “duralumin” technology in the championship class expense of building a traditional Р2С, n unfortunately has a negative side. First of all it concerns the mass popularity of time. The fact that the technology which provides the elite group unikalnye results, not tan available in regular krukowski conditions. In Patni to apply the techniques of the masters also do not necessarily guarantee expected performance and technical data in connection with many subtleties at all stages of model generation. Moreover, starting from the selection of raw materials, adhesives, technologies, tooling and ending with the balancing and debugging machines, originally designed under a single superdigital. Important is the problem of the scarcity of the same materials and adhesives.
To get out of the closet was an abandoned jig saw for cutting wood you will make, we are sure depicted in these figures are delicate fixtures. Like lace, they delight the eye with their patterns and fit well into a modern interior. This lamp will decorate the hall, but dining room, kitchen, office, nursery, bedroom — any room where it will blend perfectly with furniture. A similar shade attracts with its originality and practicality: it will never be broken, and the material for its production is readily available is any seasoned plywood.
Now, when the time for establishment of school of a subclass of car “E”, in most circles, the problem of designing and building simple micromachines no longer exists. Thanks to the experience gained with it without struggling and novices. However, all this is legitimate when it comes to simplified likes, not tied to specific vehicles, and even the choice of the optimum scheme of the chassis models of any type and class. When the boys, having studied the basics of avtomobilestroenie, go to E-polyopia in front of them immediately raises a number of questions. And no wonder — the level design here on the head above.
“M-K” can rightfully be considered one of the founders of velomobiles in the country: in its pages appeared in 1976, the description of the first, still largely imperfect muskurahat Vita. Remember! And folding ludikar “Hummingbird”! For 15 pet journal also regularly acquaints its readers with the most interesting diys.
In the practice of homebrew somehow less common device is a bending machine. I don’t think this is due to the rarity can be accomplished with it operations, rather — the lack of information about how to do it. For example, I haven’t seen in magazines or technical literature his descriptions. But this simple tool is very useful: it allows even unskilled wizard efficiently curving blanks from sheet material. This ensures the absence of deformation at the bent portion of the sheet, making it impossible to achieve using the traditional mallet and mandrel. Experienced in the production of our NII bending machine proved to be indispensable in the manufacture of chassis of radio equipment, various housings, casings and connection sheets in the fold.
Unusual “Junior; model class г2А. the description and drawings which were published in “M-K” № 10, 1993, said a surprising impact on the foundations of our reasoning krukowski theorists. Disputes regarding this model were many, and in the end the boys to vychisleniya truth even built exaggerated flying “test layout”, which was legalized in their brain is given in the publication of the First display after “wow guys seems to have decided to take up the manufacture of good oblagorozhenny machine kapatiran engine. But then, it seems, even to his own surprise, he bowed to the idea to develop another idea, which ended the above-mentioned article, In the end we managed to implement an interesting high-speed model-a duck with it and also with the design and g are susceptible of experimental techniques we want to introduce followers aeromodelling class F2А. Perhaps it will help to create not only a “Junior” but also the current championship, very promising “duck”.
