Cord model gyroplane with the engine MK-17. Readers of the magazine “modelist-Konstruktor” no need to explain, what is a gyro. However, the current model airplanes, most likely, have forgotten that such rotary-wing aircraft exists. But in the 60-ies of the last century among the approved classes, there was quite popular at korovikov class of models of the gyros, of the competition which was played at all levels up to the national championship. Today these rotary-wing aircraft create a few modelers. In this publication an attempt is made to awaken interest in this fascinating aircraft.
IN THE SKY ON THE ROTOR
Can I wash my car three or four bottles of water? Yes, if you use basic detergent device consisting of conventional brushes, cut hose and plastic bottle with capacity of 1,5—2 liters. The hose with one hand and plugged the end with wire twist attached to the brush; on its surface, which is hiding under the stubble, the hot wire is burned a series of holes with a diameter of about 1 mm.
For residents of the Urals, Siberia, North, Far East (that is, the most part of the country) the need for such a car, as the Rover is simply a vital necessity. The reasons are many: good roads are few, the terrain is rugged in the winter almost six months of deep snow, and in the off-season and even during summer thaw. To get a car, not afraid of off-road, always wanted me. Of course, corporate SUV, for example, “field” on the tires (this machine is already twice as expensive as usual) — I can’t afford. However, (probably from the perfectionism of my character) and a homemade all-terrain vehicle (one of those that often collect enthusiasts with their hands), and that the car is difficult to call, I, too, was not satisfied: I wanted to have something more.
Everyone who did the ship models with the electric drive, are familiar issues associated with power supplies. Often have to upgrade the batteries, but they are not cheap. Hence the continued interest manifested by the modelers to the idea of replacing the actuator. For example… steam, which no power supply is required.
It is only at first glance, the little things don’t mean anything. In fact, a lot in our lives (if not all) decide they. Though in different ways, depending on what it is about the little things. Some, for example, can influence except on the person’s mood, while others can even change the fate of humanity! Refer, however, to those really small things that, say, make things around us easier, safer and more efficient.
A reader, after reading the title, will exclaim: “What can still come up, because the shovel, and wheel has upgraded to the limit!” It turns out that you can. Absolutely unexpected application of the digging tool was published in the newspaper “Belarusian hour”. The author of the “open” wished to remain anonymous, but there are innovators, dorabotali design a one-wheeled carts, resembling a wheelbarrow.
In cars plastic wheel arches, as, indeed, many other non-metal parts attached to the body with screws as”screws”. After a few vyvorachivayu-svorachivanie fasteners (or vibration in the process of operation) the hole is developed and the connection weakens. When tightening the “screw” is rotated.
A lever mounted on the rake (figure 1), will greatly facilitate the work of the gardeners when released from the teeth of grass or foliage. Make it from steel wire diameter 6 … 8 mm. When upgraded rake clogged with grass, it is enough to click on the handle and continue working.
The vehicle is made according to the scheme proven by the tractor “Kirovets”. He has the same “breaking” the frame and drive on both bridges. What gives? First, the good permeability. Frame, continuously curving, as if tracking the terrain. All four wheels are constantly in contact with the surface. This eliminates the overload of individual wheels and slip them on the uneven ground. Second, increased maneuverability. The hinged frame is sensitive to even the slight deflection of the steering wheel and allows you to turn almost on the spot. Thirdly, constructive simplicity. In this scheme, you can use exactly the same front and rear axles. Simple turns and the engine mount.
For cultivating soil in garden plots most appropriate mechanism to consider a walk-behind tractor. It has a small footprint and consumes few fuel, has the necessary agility and sufficient performance. The possibility of a quick change to some tillers tillers for others (e.g., plow cultivator, cultivator or Hiller), makes this mechanism almost universal. If necessary it can adapt even under the vehicle to transport goods for short distances on farm roads.
