Specially for shelling rudonosnykh clouds, bringing icy “buckshot” for planting crops, created rocket the Cloud. The task is simple — to convey and spray and mid clouds of so-called reagent, iodide of tin, and a parachute to return to earth. And with “protographium” menacing cloud becomes a different person. The introduction of iodide tin completely changes the conditions of the formation of precipitation, and instead hail from the clouds will pour down life-giving rain. In some particularly difficult cases conducted emergency surgery — the cloud is fired on the approach to agricultural land. And then hail, which can not handle even a chemical reagent, the precipitation in the place where he will not bring harm to useful crops.
Enjoy well-deserved popularity at start-avtomodelistov kordovye racing snowmobiles and cars. Probably every athlete, behind which there is victory, not the competitions of the highest rank and world records, began their journey to the heights of excellence with such uncomplicated “Vertol”. The advantages of the aeromobile is their “all season”. Boy, replacing wheel model horses, can train in winter. But how hard would it be to force yourself to stand up for plumbing bench almost every day if the nearest exit to the Assembly lasted for long autumn, winter and spring…
Troublesome activity, building profiles of the wing flying model aircraft. We have to count tens and hundreds of the coordinates of the ribs in accordance with the selected size of the chord. Using the usual linear, it is difficult to determine with sufficient accuracy the true value of a cross-section of the eye does not “catch” and a few tenths of a millimeter… And it is from these shares often depends on the manufacturing quality of the wing model and eventually its basic flight characteristics.
Good appearance good passport data, quality performance — these are produced in our country in large series compression motors CSTOM-2.5 D. But unfortunately, not every of them work confirms promised in the user performance data and the resource. Instead 0,34 HP at 16 thousand rpm with the standard propeller 200×100 mm we had great difficulty in achieve a 70-80% capacity, resources are often limited to running, bad engine run, requires careful adjustment.
High speed car with remote control and internal combustion engine for twelve year old boys? I will say, this is not serious? The creation of such machines is the “aerobatics” automodelisme available Only to qualified athletes? And then teenagers…
“Unsportsmanlike! It is helpful to build models, not to bring equipment adult athletes! Not to allow for competition!” These indignant exclamations addressed to our children when they first presented their new microglossary in on a meeting of young modelers. We were convinced opponents and judges that the lightest devices built by the hands of boys, and not only built, but also well-designed by our sportsmen-beginners. Talked about how it was created, the new design scheme, how to construct the model. Gradually distrust, squishie in the eyes of the “enemy”, beginning to be replaced by sincere interest. But honestly, we left with the impression that to fully dispel doubts rivals failed. Especially after it started, when our gliders come with speed only slightly inferior to the results experienced athletes. And this is without the resonance of the exhaust pipes!
Many questions arise in the manufacture of superstructures of ships models. One of them was how exactly to bend the plastic sheet to the specified angle. Gluing the individual sheets requires Stripping of the obtained joints, and the result is worse than when bending. So we invented a device, which considerably facilitates the bending process. It is used in our group is not the first year and fully justified in the case. It is easy to make from scrap materials, using a pattern; maybe you differently decide the fixation of the movable part at the corner. Recommend about tilting part of the table to place transporters a more precise adjustment of the fixture.
Two world records set at international competitions in ship modeling Soviet athlete, master of sports of international class G. shahazizyan. It happened at the starts in the Bulgarian city of Tolbukhin, one of the records was blocked in the B1 class the previous results from 24 km/h! The event is really unique — even a fraction of a percent increase of speed required for approval of the record, are designers and athletes at the cost of tremendous exertion.
Microgravity class F3A are becoming more popular. However, their production is possible only to experienced modelers. Teenagers need a compact, simple to assemble and easy to use flight model of a simplified scheme under the compression motor small cubic capacity. Initially, we expected it under domestic MK-17 “Junior”, however, due to the low location of the tank the motor was bad possivel fuel, and had to be replaced compression “Meteor”.
