This two-cylinder engine, which received the name DD-700/40, designed and built the head of the public design Bureau “Aerocam” George Dorfman. The motor turned very good: reliable, relatively simple, easy enough.
…Lined up at the edge of the pond, the boys tensely listened to the pre-launch countdown seconds. In the right hand each refined model of aeropittura, left index finger slightly trembling, touching ready to spin the propeller. Finally, the command: “Start!” Engines do not fail young athletes; almost all microSD rush to the opposite shore. And what is happening in the ranks of the fans!
In “M-K” was published, the drawings and description of electric spinning-wheel; material found a ready response among our readers. However, some believe that an electric spinning wheel to use is not everywhere and not always convenient, and therefore asked to talk about simple, non -—, “grandmother”. For Example, N. Konovalov from Transbaikalia wrote us; “In the village of Russian Samobranka a necessary thing, and the city will come in handy too. But the thing is that artists who could make this old tool with foot drive, virtually no.” We offer you to become the master, the drawings and description of a spinning wheel is given below.
Simplicity in manufacture and maintenance, reliability, versatility— these are the qualities that I wanted to achieve by producing tillers. Now, after two years of operation at the farm, I can say that the goal is achieved: the machine has become an indispensable helper with a set of attachments walk-behind tractor is used For plowing, cultivating, hilling, harrowing, and in winter — to clear Paths of Snow. In the coupler with a single axle cart with a wooden body and driver’s seat, turns the self-propelled chassis carrying up to 200 kg.
For many Amateur designers is one of the most challenging elements is the frame. On it are mounted the main aggregates, it determines the strength and dimensions of the future car. And to make the most simple and reliable — welded — not always possible. That’s why published in one of issues of “Panoramas “M-K” design of motor-plow assembled on the base frame from the bike, interested many of our readers. About your veloplugs created by podcast magazine, says our reader of the Kharkiv region, V. A. Zayets.
Continuous improvement of engines and circuits cord boat allows them to develop increasingly high speed. Along with the design changes and the appearance of the apparatus Particularly dramatic changes have undergone recent high-speed model with aerodigestive. But in the class A1 scheme over many years remains, essentially, unchanged. Most athletes prefer to speak with a reliable traditional pattern: vertical location of the engine at the main building, equipped with two additional floats. The most careful attention is paid to Moto installations.
In the “M-K” No. 4 in 1983 was about a cord of car-class copies of “rally”, developed under the direction of E. Voronin. The design proved so simple and reliable that are built on published drawings of a micro-Skoda is not the first time, always steadily showing high results. I especially want to mention the original and again is extremely simple in scheme and execution of the automatic control (hold set) speed.
We are all accustomed to the fact that it is a machine fit only to acquire initial skills of piloting. In most cases, training is built almost without any requirements for in-flight properties. The main thing — to provide the maximum ease of manufacture. Eventually, when the athlete will be accepted for the design of the following models with which it will compete, will be subject to calculations and aerodynamics, and strength of materials, and materials science. But at first — what to suffer, whether… And see the light polulotosa “snags”.
The proposed design is the winner of one of the contests of velomobiles in the Lithuanian city of šiauliai.
