Long-awaited summer, and with it the time of descent of your windsurfer on the water. But how to start it moving on the water surface? How to rotate? And it is at first, and perhaps most importantly, to get back to shore?
On the coast of California, Hawaii, Australia, that is where the huge surf rolls over the waves on a sandy shore, has long cultivated an unusual sport — surfing (from the English. SURF — surf). Places to practice them, not so much on the globe. This geographical injustice brought two Canadians, James Drake, and Freda Payne, the idea to arm the surfboard that athletes use to slide from the crest of a wave, swinging mast with a sail. “Hybrid” was extremely successful projectile so peculiar a nature that to speak about Windsurfing (so the designers named their offspring) should have already how about a brand new sport.
Thanks for the favorite magazine, which can be prescribed and stored since 1976. Many articles and tips from it helped in the construction of improvised equipment or improve production. My last design — a tractor, “CHILD”, named in honor of his grandson, who never miss an opportunity to ride with grandpa on his knees.
In every town and village there is a quiet side street with a slope, where you can organize exciting competitions manicurists. But for this first you need to build the minicar. Here, everyone takes the opportunity to demonstrate the ability of the designer and designer. I hope that the published projections minicar and its appearance will help you in the design and manufacture of this most affordable car for Teens.
to Build a simple, unpretentious and reliable car I can say, came from humble circumstances. In the late times of General scarcity, I bought a well-worn “Zaporozhets”, which stood more to repair than went, expecting when I will find the right spare parts.
The letter came from the Bashkir village of chishma from the subscriber of our magazine Damir Danova. Damir talks about his neighbor — the avtokonstruktor-enthusiast Alexei Maskaev, which, while still in school I started to build different machines.
I created the all-terrain vehicle (developed design and manufactured a working model) is designed for movement in cross-country. The Rover has a two-piece articulated frame and wheels in the form of hemispheres. The turns are produced by the simultaneous “turning point” of the frame and tilting of the two axial pairs of wheels, and therefore the maneuverability of the Rover is almost the same as that of tracked vehicles.
When my son was little, I made him a car so he rode and mastered driving skills — in fact all the controls on it, like in a real car. The body of the car — carrying. The frame is made of wooden bars and covered with plywood bakelizirovannoj bottom, and sides — hardboard (MDF) Read more…
Unfortunately, experience manufacturing propellers for the Amateur designs with rare exceptions not worth repeating. And perhaps the main cause of failures in the inconsistency of the parameters of the propeller with the engine performance. Often Amateur designers create too “heavy” in the wind against the propellers, causing the engine not developing full power and thrust is insufficient.
The proposed design is a four-section, three-man boat with load capacity of 320 kg In tourist trips she, being dragged to the Bank, turns in a fairly spacious “tent”, especially if you throw on top of a piece of plastic film. The boat is so simple that it can make even a person unfamiliar with shipbuilding and have only basic skills working with wood. To manufacture do not need special equipment and space, the whole boat is going in the room of a city apartment. It is made from widely available materials that can be Purchased in stores construction And household goods. The cost is Approximately 20-30 rubles (in passing it should be noted that for the registration of boats is necessary to keep all checks and receipts).
