Throughout the military conflict in the Persian Gulf (operation “desert Storm”) in most of the media’s constant attention was paid to the action of the American missile defense system “Patriot”. Its successful use against Iraqi “Scud” (see “M-K” № 8’92) launched on the civilian facilities of Israel and Saudi Arabia, was rightly described as a triumph of modern military equipment.
In the competition of young avtomodelistov as the winter sports season and summer now dominates the aviation scheme snowmobiles and cars. Their scheme is already thoroughly known and, seemingly, has already passed all stages of perfection. Studied and worked out every knot simple models, clear design principles from the point of view of simplicity and reliability, stability of motion and speed of the turn.
For those who have passed the first stage of learning the art of radiopilot on the simplest gliders and pondered the project of the first motor cars will probably be interesting and useful the following information. Season 1992 among beginners-“radio operators” in Moscow conditionally passed under the sign “Terry” (so-called set-make a learning engine model by “Graupner”) — so a large popularity of the scheme is a good small model.
No short supply differential or planetary rotation mechanism, able to somedelicious nor difficult to manufacture the overrunning clutches is not required for the mini tractor (MT). The torque here is transmitted to each of the drive wheels regardless of their… of the motor. Moreover, the design of the machine is that allows you to change the ground clearance and track.
Judging by the letters received from our readers, many are passionate about creating copies of ships relished compilation copyright materials that reveal various secrets of working on microcode. Today we introduce modelers with experience A. Krainov. THE COPYING SCALE. In the XVII—XVIII centuries, when the craftsmen of that time were created many surviving to the present day models of sailing ships, there was developed a scale based on calculating dimensions in feet and inches. The tradition of the choice of scale has passed through the centuries, and today the most successful I must admit 1:32 and 1:4B. The thing is that in accordance with the laws of copying all the elements of the model should be made of the same materials as those used on the ship prototype. And details such as the shape of the ornament, sculptural elements and other details of sailing ships, when smaller scales cut out of wood or bone is extremely difficult.
To join automodelismo the summer holidays will help is quite simple and yet quite successful design of a sports car. Created in Leningrad by modelers, it has proven to be promising for wide use in the self-similar circles pioneer camps, clubs of technical creativity in the community and at home.
Student design Bureau of Moscow Institute of civil aviation engineers have long occupied a leading position in the design, construction and research of trikes in porridge country. In the “M-K” has repeatedly published materials activities of SKB MIIGA; the last of them (“del’talet becomes a profession”, “M-K” No. 4, 1990| caused a surge of reader interest to the student KB.
Where to start! This is the question asked by many novice rocketmodeler. What model to choose and what technology to build it! In our opinion, a good help in this will have material prepared at the request of the editors by S. Karasinym, supervisor of the club Houses of children’s creativity on Vasilevsky island of St. Petersburg.
Doing for a long time, the construction and operation of velomobiles (was a prize winner of all-Union velofestivalya in šiauliai), I was convinced of their lack of practicality. The large size of the velomobile exclude the possibility of its storage in the apartment. Known foldable construction is complicated to manufacture and quite cumbersome. Used them on wheels, usually a Bicycle, not designed for the lateral loads experienced by the velomobiles on the bends.
