BOAT-PRAMOD

BOAT-PRAMODThe problem of choice of the first model arises not only to beginners but to the heads of circles: what computers have to offer first came to class? After all, you need to choose one that is not so difficult to build and which will not test the patience of the young shipbuilder of his “mnogozadachnosti”. But the model should have good performance, not to stay in last place in the competition, and appearance as close as possible to this ship. All the required qualities have proposed a model-“Pramod” class EX-500 (polyopia length up to 500 mm). Its able to build even a novice athlete, working independently, without the help of the instructor.

UNUSUAL GIFT

UNUSUAL GIFTIt’s a letter to the editor. In it two leaves of sketches on the reverse side of which a short description and a few photos of the model. No return address, no signature of the author. What is it? The mystery still remains unresolved. But one thing is clear — sent material about Cordovan Aero glider will be important for athletes, both young and experienced. Proof the experts say to any of the claims from an engineering point of view is not the “fault” — all the calculations are justified! The editors decided to publish the anonymous letter. Because navarana if not the overall scheme, at least part of the individual decisions will the creators of sports technine tomorrow. We can only thank the stranger who made such an unusual gift to readers-modelers. So, we give this letter.

AND TRUNK, THE AERODYNAMICS!

AND THE TRUNK - AERODYNAMICS!For a start I suggest the readers-to motorists to conduct a little experiment. Once outside the town, stop by high-speed stretch of highway and watch whizzing past you cars. However, here you need not to watch but rather to listen. A quarter of an hour you will learn to distinguish aurally, the main types of cars: a sound portrait of the major role played by a characteristic noise of the flow over the body. But here comes a car with a roof rack and audio, the picture changes dramatically. The impression is that the car literally pushes through the dense unyielding environment. By the way, the impression is confirmed by experiments in wind tunnels. Purge models and full-size cars with roof racks have shown that increases dramatically the so-called Cx is the drag coefficient. But it depends on the speed and fuel consumption.

CONTRARY TO TRADITION

CONTRARY TO TRADITION“Made without balsa? Then bad!” — is unexceptional opinion about aerobatic traditionally there is a perception among most athletes. Especially categorical estimate the model from the point of view of its material beginners — experienced only pilots first, to clarify, do not use fiberglass.Maybe you shouldn’t be so categorical in his judgments
only “dress for success”? Ultimately, all flight properties of the model do not depend on the used materials, the main thing — successful, from a design point of view, a well-designed power and aerodynamic configuration.
An example of this is the proposed flight, which can be collected even on the kitchen table from readily available materials.

NEW LOOK – “JAVA”

NEW LOOK - It is well known that the wind fairing is not a tribute to the motorcycle fashion, and not only protect the rider from the cold and dirt. A well designed shield can increase the speed with two-wheeled machines due to the reduction of aerodynamic drag. But the appearance of the motorcycle fairing attaches to consistency and completeness: the motor vehicle acquires its own entity, releasing the car in several thousand likes.

OUR ORDOVIKE THE BEST IN THE WORLD

OUR ORDOVIKE THE BEST IN THE WORLDRegularly model airplanes-conovici come to the world Championships, to hundreds of athletes to identify the most strong, the most experienced craftsmen. Last year the venue was the Hungarian city of PECs. It was there that he developed air battles in the four most popular classes cord models — aerobatic, speed, racing and fighting. All four classes and in team and individual competition — confidently leading modelers of the USSR team. In the end, the gold medal of the FAI and the title of world Champions respectively, got A. Kolesnikov (Frunze), Kalmykov (Moscow), the crew Barkov — Suraev (Kharkov) and N. Necheukhin (Sverdlovsk).

THE SEARCH FOR A COMPROMISE

COMPROMISEIn the “M-K” (No. 11, 1990) was described by the model of the strongest tracks. However, the production of such equipment is not available to everyone and is quite expensive. And what do the athletes do not have much experience, and beginners in the club? For them it is proposed to develop a model of THE class-2 modern design, but runs out of available materials and without using complicated technologies.
