Category S4. The rocket plane is an aircraft that is lifted into the air using the thrust of the rocket engine, and returns to earth planning with the engine off — using the aerodynamic lifting force. This requirement applies to all three categories of rocket gliders for the duration of the flight — S4, S8, S10. And each has its differences. S4 — model glider with an accelerator, which can be separated during the flight. S8 — model RC rocket glider S10 — a model rocket with a soft wing (wing “Rogallo”).
MODEL ROCKET GLIDERS
As you know, in a two-stroke motorcycle engines bearing-connecting rod is one of the most loaded nodes. At the same time, its technical condition depend on time and the quality of the engine. To determine the wear and furthermore make the necessary repairs without dismantling the crankshaft is almost impossible.
It would seem, what could be better than a propeller! Decades he is the right person, moving a variety of the court, ranging from simple walking equiped to giant supertankers. Well-developed theory and calculation methods allow a precise adjustment of the screw to any of the designed ship.
“Dear editors! I recently bought in shop “Children’s world” microelectronical, but when I put it on the model of the torpedo boats, it is a day out of order. Please advise, can it be repaired and how?
Often you can see guys, sorry standing at the wreckage of his first cord model aircraft. Many fail the rocking of the control — or done poorly, or the material is picked up correctly. And so I want to see in flight almost a real plane that you yourself invented and built!
Experienced modelers-conovici much focus on connecting cords and the rocking the control cables. Especially careful they draw their conclusion from the wing — this often depends on the successful flight model as in training and competitions. Accidental kinking of the cable pull — and stuck in the system control leads to the fact that the miniature aircraft crashes.
The model we offer you to make, made by rare scheme — two bearing rotor during rotation intersect. To build it is not very difficult — especially as the engine are well-known modelers rubber tubing. Energy stored in them when you twist, enough to fly a small model of this type. The diameter of the rotor is 600 mm, and each of them has its own shaft, both rotating in opposite directions, which provides a synchronizing mechanism. Four gears cut from metal gears with a suitable external diameter, which you can pick up from parts of an old alarm clock or a broken clockwork toy. After processing, the thickness of each gear should be about 2 mm, the diameter of inner hole is 2 mm.
“They are not afraid of obstacles!” this is the motto of our magazine a few years ago began to publish descriptions of the designs of a homemade all-terrain of micro-technology, immediately attracted the attention and then the affection of readers. During this time in our regular sections “Public CB “M-K”, “Create, invent, try!”, “Competition of ideas” we talked about many unusual and original machines: all kinds of snowmobiles and amphibians, multiwheel and tracked micro cars, motonartah, sports-dirt cars buggy, snowmobile. In this opening year we introduce another interesting development — snowmobile “Triumph”, created by the designers-lovers from Saratov O. YAKOVLEV and V. SIDE.
On the opposite slope of the ravine, where a tower stretching up gold under the bright winter sun the trunks of the pine trees, down the skier. He rolls down the fresh, the night fell and now fluffy clean snow. Here he turned sharply across the slope, holding up a snowy trail, I stopped for a second. And down again again towards. Steep sharp turns, dive and stop. Skiing will not do so, even on the mountain, even on a solid Naste. Yes and it is something special — that a back, face to the slope. Everything he gets is free and easy, only one little tilt of the body, it seems almost effortless…
Motorsport fans have long been familiar with the term “rally”. He is known and automodellista-skorostyam is one of the competitions cord racing models, in which miniature cars shall adhere to the set speed. And in the near future the word “rally” will appear in the lexicon of car designers-copies.
