We present radiomodulators development created by Czech athletes. Although the model presented by the authors as “glider”, its capabilities are much greater. Suffice it to say that a powerful engine with a working volume of 3,5 cm3 this machine can even be used as Aeromexico to slip the glider with a wingspan of up to 2.8 m! Very good “Stratos” — is the name of this interesting aircraft — and behaves as a purely motor technology, and as a glider.The basis of the fuselage are two symmetrical side cut from balsa wood with a thickness of 4 mm. In the front they are strengthened by adding plywood with thickness of 1 mm. from inside the Engine compartment on the sides further inlaid balsa thickness of 10 mm, which allows you to securely attach engine mount out of plywood with a thickness of 9 mm. the Tail part of the fuselage assembled using balsa stringers and racks section 3×6 mm.
THE GLIDER, BUT NOT ONLY
Limitless Russian expanses, but in winter their snowy immensity had become impassable for virtually all vehicles. That is why with the advent of powerful internal combustion engines, the designers started thinking about creating machines that are able to easily overcome this “snow-covered vastness”. The choice of propulsion device for a snowmobile vehicle, it was a small caterpillar, wheel Yes auger. In combination with the supporting pillars, mostly with skis – at the beginning of XX century was built a lot of all kinds of snowmobiles. However, such machines did not have either the terrain or speed.
The proposed development is suitable for plowing the infield with a small plow, loosening the soil using the excavation tool. In addition, this cultivator can perform the planting and ridging of potatoes.”The heart of the” mechanical assistant (power plant) the engine of the scooter Elektron with forced air cooling and handles the throttle and clutch (with cables taken from the same scooter). The drive sprocket of the engine is also “a regular”. Gear changes can be left motorolleri, rope. But it is more convenient to bring it directly to the spar tillers. The programs will switch with levers and rods.
Modelers – people are scrupulous, and appreciate when a replica model of the aircraft, ship or tank is not only the most similar prototype, but repeats it in great detail. Imagine that you will be able to demonstrate a model of passenger airliner or fighter jet, including the main design elements of its engines! Today we talk about how modern aircraft gas turbine engine (GTE) and why building it requires a higher skill level. This publication will also be useful for followers of simulation, shipbuilding and armored vehicles. Because it is often under the deck of a modern ship or under armor tank is still the same GTD.
The boats, which we would like to introduce to the readers, it can be attributed to the category of small vessels. And how else to call a couple of universal self-propelled floats, which are easy to use and as gidroliz, and double pleasure catamaran. As can be seen from the drawings, each of the floats is a miniature boat with a power unit including battery, motor and propeller. Displacement of one float is about 140 kg, which allows not only to equip its power plant, but also allows for “skier” when you need to rely only on a single float, not fearing that he will go under water.
Many are addicted to fishing for them this activity is a fascinating vacation. The very same UDA, rod, adise is one of the oldest fishing gear; by definition of V. I. dal’s dictionary, it is “spun horsehair forests, with one (or more) hook, which is sometimes linked to special powada; hook is attached above the sinker, above, depending on the depth, the float, the upper end attached to the rod, the shaky stick”. However, progress is inexorable. To replace the forest horsehair came nylon fishing line, floats of nylon and become electrified. Improving manual fishing gears and devoted this article.
