Very often the students see on television or in a magazine, the launch of the spacecraft, have a vital interest in how this happens. If I could build such a rocket! And-models are very close to real rockets: same shape, only the size is much smaller.
-Models of missiles play a big role in aerospace education of youth. In the process of working on them, “the rocketeer” learn to read, match and draw up the technical documentation, get acquainted with history of creation and development of space-rocket techniques, study design missiles. At the same time, the process of learning the fundamentals of designing and manufacturing of individual components and the whole model. In this creative process, develop skills of solving technical problems, chief of which is the creation of a flying copy of the rocket.
Mini makiki always use the boys great success. And for good reason! Small size, cost-effective, modern appearance, excellent performance — what more can you ask for? Maybe that’s why many of them roll up his sleeve so take tools. After all, if you try, you can do mokik, able to compete with serial two-wheeled machines. However, it is not very easy, but it’s worth it.
Design truck for paraglider was preceded by just the fascination of paragliding, which did not come at once. First flew airplanes (and flight certificate), gliders. But one day, fly a paraglider, got into it seriously. I think it is comparable to swimming to sailing. Only even better.
Frame double machine, dubbed “mouse”, welded from thin steel tubes. Front axle (Fig. 3) assembled from beams, two eyes and swing units of the front wheels. Axle are the axle adapted to pivot the sleeve at an angle of 98 ° and welded to it. Pivot arm has a bend of sheet steel with thickness 1.5 mm; pivot bushing it is attached by welding at an angle of 110°. Ring tail joints at the ends of the swivel levers are cut from steel pipe ø 12 mm.
A few years ago for her sons made a small recumbent (and judging by the size or design — it would be more accurate to call it melakarta). Children machine like, and they, along with the neighborhood kids for hours chased her down the quiet streets.
Last summer, the head asiacruise Vnukovo house of culture (Moscow) Amateur pilot, Andrey Chernikov demonstrated are designed and built with his own hands a single biplane rather complicated maneuvers over the airfield Expanse in the Vladimir region.
The court, using for movement the muscular strength of a man, never belonged to the category of speed. The only exception is racing boats for rowing, which is the most fleet of vessels musculoides. Due to their known good configuration and the most complete use of the muscle energy of athletes, boats-“eight” is capable of two-kilometer distance to reach the speed of 12 knots. But this does not mean that this speed is the limit of possibilities of human movement on the water surface. If you deviate from canonical constructions of rowing boats, designed for official competition, then there is a possibility of creating a spacecraft-muskurahaton reach speeds up to 20 knots!
Before you start talking about the car “Adrenaline” – built student engineering group of Moscow automobile and road Institute (MADI) to participate in the international competition “Formula Student”, it is necessary to say a few words about the history of this event.
Despite the fact that the industry produces many different small vessels (including yachts), the number of homemade, Amateur-built, grows from year to year. They boldly experiment with various materials used in their projects are interesting technical solutions.
