When developing this design car trunk, the task was to create a device which, in addition to the normal daily functions would satisfy and lover of outdoor activities — would allow us to transport two sets of boards sailing in the summer and (with minor changes) 5-6 pairs of skis in the winter.
They say everything old is new again. And energy here, it seems, is no exception. Burned on Chernobyl, faced in some places with the threat of an energy crisis, mankind increasingly turns its gaze on technical solutions, unfairly written off in the past in the archive. The use of the gratuitous forces of the wind among such solutions. Come to them in their creative pursuits and like to make things with their hands (see, for example, “M-K” № 4/84, 5/86, 6/90, 7/92|.
Before copiers that manufacture aircraft models in the Mel scale, often raises the problem of simulating a power plant with a radial engine. Offers an unusual method based on the use of… conventional steel screws or bolts. First, you need to pick up screws with fine or medium threads, the outside diameter corresponding to the cylinder size of the engine. The screws are trimmed to length and with one edge sharpened needle files tapered tetrahedron (the angle and depends only on the number of cylinders). Then, treating the sharpened surface etched with acid, they oblizyvaet using a soldering iron.
Practice starts in the competition boat-“bramahadev” convincing evidence that until today the question of establishing a simple and reliable device for shutdown of main engines after completing the scoring of the race remains open. That is the problem and is dedicated to offer modelers the material.
Even perfectly executed a valid copy of a military ship or self-propelled artillery loses much if its design does not allow to simulate the use of the main weapon of the prototype. But most known simulators does not provide the sound similarities with a shot or hampered their placement.
Hand tools for mechanical cutting of bushes etc. green spaces developed a lot. Including Amateurs samodelki (e.g., see the publication “M-K” № 6, 1985 on universal electrocasnice ESC-1). But in all designs I’ve ever seen, their engines, fitted, which, of course. can impact the cost of the manual tool.
For millennia sail faithfully serve the people, helping them overcome the seas and oceans. But under the onslaught of steam and electricity, he had to concede the monopoly of the single marine propulsion. There was a period when the sails almost disappeared from the water expanses. And still thirst for romance, the desire to test their strength in single combat with the wind and waves in the soul of man died.
