THE WIND IN THE CONTEXT OF

 

The sail of the windsurfer is not the only element that produces thrust, but “the wheel” for manoeuvring. The air flow at the surface and water has a lower speed than the wind at a height of, say, three meters. Therefore, the load on the sail (corresponding speed) are proportional to the height from the water level and each overlying section of the sail will receive a certain twist in relation to the underlying (Fig. 1A).

MANUFACTURER GUCHKOV

 

Gucci rider is two arcs, glued wooden slats and the United front a metal band, framed with a soft rubber bumper. Shkotovo (rear) ends Guchkov have holes through which the sheet (rear) corner of the sail go to the ends of the nylon stoppers — sheets. The stopper is placed on each gig in a convenient pull-up or weakening of the Scots place — it allows on-the-go to increase or decrease “belly” of the sail.

That move through the water can be sitting for the PA log, and water starting from the first available under the hand with a stick, has been known for many thousands of years. For such a considerable historical period inventive humanity thought of a hollow log in the recess and that the horses of the stick to shape in the form of a paddle. In our time as a technique and the means of rowing remain approximately the same as in the days of the pharaohs.

In many CUT and suit (clubs and centres for young technicians) a section of the kart. Little machine not only helps children to learn the overall concept of the car and learn the basics of his driving, but many of them, it’s blazing a trail in the big Motorsport and reveals their ability in technical work.

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.

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.
