Weather did not spoil the young glider pilots. The sky is high and blue, as it often happens in Lithuania at this time of year, gray and low down over the green field airport. Strong gusty wind ruffled over the hangar zastiranny rain striped “stocking” of the determinant of the direction of the wind. Chief judge of the competition Mr. Canario and then looked at the clouds, thinking, not whether to cancel flights. And even newsreel cameramen from Perm, arrived to make a documentary about his countrymen, the young athletes from the city of Lysva, are unable to resist the complaints about bad weather, because color film, as is well known, loves the sun…
GLIDER OR GLIDER? Unpowered gliding flight has long attracted man. It would seem that what is easier is attached to the back wings, jumped down the mountain and … flew. Alas, many attempts to rise into the air, described in historical Chronicles, has led to success only in the late nineteenth century. The first glider was a German engineer, Otto Lilienthal, glider balance created is very dangerous to fly the aircraft. In the end, the glider of Lilienthal killed its Creator and brought a lot of trouble enthusiasts gliding flight.
While the British Admiralty systematically extinguished the enthusiasm of its inventors-“submariners” in former British overseas colonies, and now the most economically powerful nation in the world, energetic engineers to continue their experiments. And, in the end, the United States has become the birthplace of real submarines, suitable not only for experimentation and advertising “horror stories” in the spirit of sir Basil Zaharov, but also for combat use.
In two decades of Windsurfing technical equipment of the sport has undergone many changes. Through the efforts of enthusiasts Board sailing from clumsy boats, is a conventional surf surfer with a sail attached, turned into a projectile, embodying the latest achievements of Aero – and hydrodynamics and constructed of materials that previously were used only in aerospace engineering, for example, carbon fiber and Kevlar.
UK-4: NEW POSSIBILITIES. I already told on the pages of “M-K” about his upgrades convenient desktop stanochek UK-4 “Skillful hands”. Today I want to share another device to it, allowing for sanding and polishing flat parts and, if necessary, to obtain from them a thin plate and even veneer. I use it for more than three years and are very happy. Recently I have improved a little, and now it is possible to grind the plate thickness of from 0.3 to 10 mm with a precision up to 0.05 mm.
In the production of parts in various circles of technical creativity there is often a need for end and face milling. In this case, will not always be able to help out and table horizontal milling machines.
Passenger aircraft DC-2 and DC-3, developed by the designers of the American company “Douglas” in the middle 1930s was extremely successful, was built in large numbers and spread throughout the world. But made on the basis of their bombers is not known by the time of the US entry into the Second world war has practically disappeared from combat units. But first they had high hopes…
Only four minutes, the athletes rakatomalala to prepare for the start. How much do you need to keep up with the time flying at the competition as if one moment: to install the model on the guide pin. To connect Elektrostal, to determine the atmospheric conditions at this point and calculate the direction of flight, accurately to execute the command “start!”.
Continuously growing speed racing car, top athletes, designers are finding new technical solutions that increase the speed of avtopoligon, new methods of forcing-engines, better ways of suspension. And as a natural result — new records. So, last year, the master of sports of the USSR, Leningrad A. Medvedev at the all-Union competition “Match the fittest” broke the record of the Soviet Union — his polutorametrovy was racing the distance at a speed of 223,880 km/h!
