I want to tell readers about the catamaran, the movement is carried out with the help of Magnus effect. The Magnus effect is that when an airflow of the rotating body formed a force perpendicular to the direction of flow. As the cylinder rotates, for example, close to its walls the layers of air begin to move in a circle, making one side of the rotating body increases the speed around a cylinder flow, and on the other side a decrease. As a result, the surface of the cylinder are formed by areas of increased and reduced pressure, which leads to the formation of forces, which can be used for ships. It is this force that changes the direction of flight of the “cut” balls in tennis and football.
We used to go fishing. On the distant lake, where pervalence always well caught pike and large perch. Our experienced “Muscovites” cheerfully rolled down the snowy highway. Quietly rustled the heater fan, the radio was flowing pleasant melody, and there were no signs of trouble. And then… Oh, it’s “suddenly”! — threw the thick snow. White muslin closed the horizon, and “wipers” hoarsely humming, barely parted namipasumu on the windshield slush.
Vertical takeoff aircraft Yak-36. In 1960, Yakovlev made a proposal to the government to develop the aircraft vertical takeoff and landing (VTOL) Yak-104. The project involved the use of two lifting and propulsion uprated Р19-300 with a thrust of 1600 kgf with a rotary nozzle and one lifting Р19-300 traction 900 kg. It was expected that at flight weight of 2800 kg and the fuel capacity 600 kg VTOL aircraft can reach the speed of 550 km/h, climb to an altitude of 10 000 m and fly to a distance of 500 km.
In the first years after the Civil war, the Soviet civil aviation monopoly reigned all-metal aircraft of the German production. “Ukrvozduhput” preferred products of the company “Dornier” and “Dobrolet” and “Zakavia” purchased the aircraft from company “Junkers”. Single-F13 for a long time was the main “workhorse” on the Soviet civil lines, and military transport. Following this, albeit in significantly smaller quantities, began to acquire W33.
On March 28 in Moscow at the Central arena of the sports complex “Olympic” will host the annual sports-entertainment show “Monster Mania” with participation of giant SUVs Monster Truck (Monster Truck).
“It is easier to pull than push” — the ancients said. Indeed, what if leading and control functions to combine in one wheel and make it no pushing and pulling! In the classical scheme of two-wheeled vehicles (motorcycles, mopeds, scooters, etc.) the rear wheel is usually the leading, front of the same control.
When Gennady Kulish arrived in Kirovohrad Institute of agricultural engineering, engineering, it, recent rocketmodeler, and in a head could not come that an important part of modern aviation and rocketry — radio location — will find application in agriculture. And that the range of agricultural machinery, he will experience no less exciting moments than with their launching of rockets.
