Historians say that the sail appeared on land about four thousand years ago! Fiction? No, the reality is — there is documentary evidence.
This is a hovercraft I built for several years. Engine – from VAZ-2108 with a capacity of 74 HP, Case – fiberglass, fiberglass epoxy resin, is made of the type “sandwich” with the Styrofoam plates. The structure weight was about 370 kg. propeller – propelling three-bladed, with a diameter of sweeping the surface 1700 mm and variable in place of step. There are still two the blower for pressurization of the airbag. Skirt the cushions are made from French awning waterproof material with a density of 600 g/m2.
I want to introduce readers “To the” constructed me an amphibian. Constructed I, in practice, to solve a number encountered in the design of problems and contradictions. There were quite a lot, but the main makes sense to call.
My buddy with a passenger all-terrain vehicle UAZ Hunter and a cargo car of the raised passableness, the GAZ-66, popularly known as “shishiga”, has designed and manufactured a single-axle trailer suitable for both machines. Specifications and dimensions of their cars, oddly enough, close, in addition to speed, however, when riding with the trailer speed is still limited. Of course, buddy could buy a ready-made trailer (it probably would have been even cheaper), but it took him not quite normal, what is not for sale.
Perhaps, in the memories of every adult baby winter fun be sure to contact the sled. And it’s safe to say that in a rare home today will not meet them: they still serve the kids and adults — the baby in daycare to take a little weight out of the house or building to deliver in the snow.
If you manage to build such menopausic, then you immediately become the owner of a “flotilla”! In fact: craft the proposed design for its small size called the author of “Hummingbird”, very simple conversion could be a Dinghy, a windsurfer, and a row boat. And it will be useful not only for recreation, but also serve as a great trainer for beginners.
AIRPLANE FOR TWO. Use of a low powered engine in a two-seater suggests several options of its aerodynamic layout. If not enough power, you can increase the load-bearing properties of the wing, increasing its area (and in the first place – scope). As an example, this approach can cause a plane to the ATL (the company “Robin”) and a series of French double units of the company, “Fournier”. These machines are made entirely of plastic and is fitted with lightweight motors air cooling capacity from 60 to 70 HP wing Area from 10 m2 and a span of about 10 m.
increasingly, in an editorial post meet the voluminous packages of drawings and descriptions of improvised microvesicles. Their fundamental difference from development of previous years – a successful combination in the construction standard and improvised units. The second important detail – the sharp improvement in appearance, a bold design decision. On these pages we present to the readers micromatics, which fully apply the characteristics set forth above.
The future of our country, its science and industry will soon begin to identify those who are now sitting at their desks in schools, in the classrooms of technical schools and vocational schools. What knowledge and skills they will get today, tomorrow will depend on the quality of scientific and technical developments, the level of our industry and the competitiveness of products, the development of the national economy.
Before you engage in the construction of microvesicle, I’ve been drawing various versions of its layout, trying on paper for all possible errors and miscalculations, which can only occur in the process. Looking ahead, it should be noted that designing on paper is one thing, fabrication is another. Many of the “roughness” out in the operation of the machine.
