Modelers in different disciplines often have to deal with the problem of determining the speed of rotation of the parts, screws, shafts, and even cassette recorders. That’s what the device advises to use well-known Polish engineer, Janusz Wojciechowski.
PROPOSED RC MODEL GLIDER WITH an ENGINE displacement of 2.5 CM3 model airplanes BUILT by the CZECH VLADIMIR BILY, IT MADE ABOUT 370 FLIGHTS (80 HOURS). THE MODEL IS EQUIPPED WITH DVUHKOMNATNAYA EQUIPMENT.
(The end. Beginning at No. 10, 1973) In the tenth issue of the magazine, readers got acquainted with the General layout of the three-wheeled micro-car, only “Friendship” design Bykovskiy, G. Malinowski and B. Horev. Today we talk about refinement and alterations to the factory components and parts that have been applied in the construction of this interesting machine. Remember that to make their own does not make sense. Even with the appropriate machining equipment it will greatly increase the cost and complicate the work, not to mention the fact that the quality of parts made in primitive conditions, much lower than factory.
DESIGN PRINCIPLES. As you know, every self-propelled model, be it a model airplane, ship or car, has a car, and, therefore, exist for them, the laws of calculation and design can be transferred on the model, taking into account the scale only. This is the first. Secondly, any self-propelled model (like any machine) includes three elements that can be considered mandatory. What kind of elements?
After publication in No. 5 of our magazine for 1972 article “Three wheels instead of four,” we received hundreds of readers ‘ letters with a request to send or publish drawings of three-wheeled micro-car, only “Friendship”, built in auto-design circle school No. 200 Timiryazevsky district of Moscow on the project of teachers Bykovskiy, G. Malinowski and B. Horev. No less — if not more — it’s letters directly to the school, where he created the first micro-car, only “Friendship”. The interest of young technicians of our country to this machine was so great that many specially came to Moscow to the Exhibition of achievements of national economy of the USSR, where it was exhibited.
No one ever sought to do so, he was chasing passers-by and deliberately crushed them. But also special requirements, stipulating it is the safety of the car, there was very little. Most of them belonged to the lighting devices Projecting the remaining components and assemblies of the vehicle, the designers were free to think about anything: power, speed, carrying capacity and so on. Safety in calculation were not accepted: the problem, as it did not exist. And of course, speech could not be about the complex constructive activities, designed to perform only one function: to provide security.
The need for such airplane appeared when our young conovici already know the basics of management “phanerogam”, and for them it is time to explore the simplest aerobatics. “Tit” (so was called the original model) designed and built in the time of winter school holidays. The club had already had the experience of starting and adjustment of the motor MK-17, so the plane was designed exactly for this engine.
The world’s oceans! Nearly four-fifths of our planet’s surface is covered by water. Always changeable and movable, water as a mysterious living being for thousands of years attracted people. Ancient water roads people overcame space in the water to search for food, striving to penetrate into the underwater world and to know him.
Amphibious vehicle design N. M. Purtova. Doesn’t that sound nice, getting up early in the morning, roll the boat out of the garage, lay a tackle, get in, press the starter and… to take the highway directly to the river. And there go into the water and swim myself to favorite places to fish.
At school, for more than 40 years, engaged in the construction of various mechanisms to facilitate workplace and at home. (In the journal “Inventor and rationalizer” was placed in my article “power saw and pump”, which caused a lot of queries.)
