Dear fans of aviation! This article may be useful for the development and construction of a light helicopter. Offer – to rotary-wing aircraft (AV-1) is the fruit of a long fascination with aviation, the result of persistent and laborious work for five years, of which two years was spent on construction and the rest for testing, debugging, development piloting, repair, upgrades.
The message of the Soviet information Bureau was, as usual, short: “” N ” the submarine of the Northern fleet under the command of Lieutenant Stolbov entered in the fascist of the harbour and attacked the transport with a displacement of 6 tonnes. Torpedoman Melnikov two torpedoes blew up the enemy ship. The submarine returned safely to their base”. This is the first military success of the Northern fleet in the great Patriotic war fell to the lot of crew of the submarine U-402, which is 14 July 1941, entered Porsangerfjord and destroyed the transport ship of the enemy. The first step was made. But the “four second” had many difficult hikes, and each demanded that the crew maximum impact spiritual and physical strength, bravery, courage and resourcefulness.
Undoubtedly of interest to many tourists are the publication of the journal “modelist-Konstruktor”. But they mainly describe the various vehicle designs and less emphasis on other essential Hiking things: tents, backpacks and the like. In recent time there appeared a large number of tents’ in industrial production, a variety of designs. However, tourists still have a desire to make your “camp house” on their own. The more that today to purchase the necessary materials has become much easier, and sewn at home, it is much (two to three times) cheaper than purchased.
It is known that in soft wood or particle Board with no nails or screws do not provide a reliable fastening, break out with “meat” even at low loads. Help out the push-pins of hard wood: they are injected with glue in predrilled holes in areas where planned hardware. Here is the connection already ensures Read more…
Moscow musician D. T. KUDRYAKOV among Amateur designers known as the author of a unique car is amphibious “Triton” — one of a kind vehicle that is registered simultaneously in two state inspections: car (GAI) and for small vessels (GIMS). Our regular readers may recall the publication of “Planing… car” (“modelist-Konstruktor” No. 5 of 1996), containing quite a full description of the construction of the “Triton”. In it the author shared his approach to solving complex technical problems, which allowed him to create a vehicle equal in their performance on land and on water.
Modern models of bikes full of new materials and technologies. But in most cases it touches the chassis, steering, powertrain. Virtually unchanged in design remains only a spoked wheel: the Central steel sleeve on the axle, steel spokes, metal rim and rubber tire on it. Of course, the inventors here do not remain on the sidelines, offering, for example, various embodiments of bushings, oval and even a variable section spokes, different profiles and material (steel, aluminum, carbon fiber) rims etc, but that does not change: spoked wheel is still the lightest, and therefore irreplaceable.
This small trailer was designed and manufactured when our family received a plot of land for gardening in the suburbs of Cheboksary. Immediately there is a need to transport various goods. At that time I had only the Minsk motorcycle and some old nodes from scooter “Tourist”. Little motorcycle and need a small light trailer. So its frame is welded from steel tubes of rectangular cross section, and reinforced body made of duralumin thin-walled tubes and sheets, securing the wings with the help of argon-arc welding. Then these two main nodes are interconnected by screws M5.
Input class EX many other differ a good combination of simplicity of their manufacture and striking appearance. Impressive dimensions and the technical equipment of these models generally provide a decent level of sports and enhanced entertainment, attracting many fans.
When soldering tin-lead solder emits vapours, which are very harmful, especially lead. The smell of rosin is not all pleasant. Some hams even have to leave your favorite passion – grumble’s household. However, there is a way to make exhaust ventilation. For example, I use this for over 20 years. When making use of almost everything is ready. The hoses and the top cover is taken from a vacuum cleaner. The snail and the impeller from the heater of the car “KAMAZ”.
Read in the “Modeller-designer” interesting article on the new generation car with aerobrigada, the boys from the circle, which I direct, has decided to develop the proposed innovation. Its essence was the transfer stabilizatory plate from the zone of slipstream in close proximity to the track surface of the track, where the model moves at a high speed must manifest the aerodynamic ground effect. Although models that are built in our group, has repeatedly won prizes in on competitions and seemed to be brought to constructive and technological excellence, yet wanted to try something new.
