The development of military transport aircraft (MTC) An-70 intended to replace the An-12, began in 1986 After seven years of tactical and technical requirements specified, wherein, based on the need to transport a medium tank, the maximum capacity of the machine increased up to 47 T. the Peculiarity of the aircraft were four gas-turbine engine with coaxial propeller-fans and fly-by-wire control system In aircraft design is widely used composite materials. The first flight of the An-70 took place on 16 December 1994 10 February 1995 and the plane crashed. To continue testing built a second model, testing and refinement which is ongoing.

Conceiving a new microplane, any Modeler primarily decides which engine to put on it. One of the motors power is not enough, others too large, others strongly vibrate during operation. Many disadvantages of single-cylinder engine delivered a two-cylinder of the same displacement. They can be built on a variety of schemes: boxer, Y-shaped, inline. In some cases, if the Modeler is not very important weight, two normal “odnotrahniki” mounted on a common metal frame, connecting the shafts through the gear transmission. This allows to raise efficiency of the propeller by increasing its diameter at low speed.
In the first rank of the best projects presented by young technicians country in the Central exhibition NTTM-82, is “Rublis” — self-propelled plow-cultivator, or, as it is called, a plane. Built this machine students the eight-year school in the village of Ruda district of Liepaja Latvian SSR, the members of the circle of mechanization of agriculture.
Cars, army UAZ-29661-vehicle with engine ZMZ-5143 98 HP and an elongated UAZ-2966 motor 9МЗ-4219.1 84 HP, which in the early 2000s were equipped with the Russian army, created on the basis of the famous UAZ-469. By this time they have, to put it mildly, could not meet the increased needs of military units. Therefore military experts had welcomed the new car – GAZ-2975, created by the Gorky automobile plant. It was an army jeep – Russian multipurpose armored terrain under the loud name “Tiger”. Its serial production in 2005 has mastered the Arzamas machine-building plant, where they were received in the Ministry of defence and the Ministry of internal Affairs.
In recent years, numerous sailing sports have added one: winter Windsurfing. At first, he spun off from the classic surfing as a way of year-round training: created a kind of simulator, which, according to enthusiasts, was to stay in shape during the “closed” waters, and also serve to teach beginners the basics of the art control boards. However, the training was so fascinating that soon had the idea to conduct a trial competition “sailing skiers”.
We have already talked about the fact that the Mediterranean powers, France and Italy after the First world war were almost no modern cruisers scouts that were at the end of battles is absolutely essential class of battle ships. This situation is every year becoming more and more unacceptable. When solving this problem, each country chose its own path. The French began a mass construction of very large superessence that was supposed to be used in the composition of teams and individual attacks, and to repel enemy assaults and for reconnaissance.
Did not have time to be approved and become a massive new and exciting sport of hang gliding enthusiasts as it took to lay another area in the technical work associated with designing balancing aircraft, — the construction of trikes.
