For the past three years an enviable stability in the class 84В shows Moscow racemode-sheet O. the ravens. It was not the case, so he did not became the winner. So the next championship of Russia, held in Orel, Oleg took the second place. To a large extent the key to this is the reliability of sports “projectile” rocket plane. N addition to the model, there is absolutely oryginalny automatic forced landing. I hope that this design will interest our readers.The proposed model is a bright representative of the so-called “Moscow” scheme raketoplana. Fuzuli — tapered beam of plastic. Its manufacturing technology Tenova. On the mandrel of variable cross section with a diameter of from 4 to 8 mm is wound first single steklotarny layer with a thickness of 0.06 mm, then the first layer of carbon fabric with a thickness of 0.12 — 0.14 mm and the second, just a length of 160 mm. then applied another two layers of glass, all carefully vyshkurivaetsya. The weight of finished beam is obtained in the range of 1.5 g.
Helicopter S-55 Sikorsky Aircraft company, part of United Aircraft Corporation, was designed and built in the late 1940-ies, during the period of rapid progress in the global helicopter industry, becoming a significant success of its designer, Igor Sikorsky. By this time, the aircraft designers and military ceased to consider helicopters as merely exotic aircraft. Before them were staged combat missions of a wide range of: supplying troops in remote areas, landing, fight enemy submarines, aerial photography, rescue of crews of downed aircraft, setting smoke screens, laying communication lines, and aerial surveillance.
The development of aircraft, initially under the designation C-80 OKB. Sukhoi started at the initiative of M. P. Simonov in the early 1990s in the framework of the conversion of the defense industry. Two years later, finally formed the shape of the aircraft as a high-performance vehicle intended for passenger and cargo transportation on domestic routes and is able to replace the outdated machines of similar purpose. The prototype C-80 with the turbo-propeller engine TVD-1500 was calculated to transport 24 passengers or 2500 kg of cargo. However, the domestic TVD the time is not ripe and had to rely on ST7-9V of the company “General electric” (USA). With them the plane could carry up to 26 passengers or 3,500 kg of cargo.
The peak of development of hydroaviation was in the middle of the 1930-ies. The main advantage of amphibians compared to ground vehicles, flying over extensive areas, it was considered a possibility to land on water surface in case of an emergency, even with waves up to five points. But as time went on. The reliability and service life of the aircraft led to the rapid displacement of the seaplane first with the airlines and then military aircraft. Operation of land planes was easier, and their weight returns payload, as well as a high aerodynamic efficiency has reduced the cost of commercial transportation. The development of the airfield network and other transport arteries, and the appearance of helicopters resulted in an almost complete elimination of the flying boat in commercial aviation. There was only a small segment of the lungs of amphibians, serving tourists and residents of remote, “forgotten God” corners of the Earth.
In the mid-fifties of the last century the theme of vertical take-off aircraft excited the minds of the designers and the military in many countries. Was no exception and West Germany. After graduating in 1955, G. ban on the development and production of military aircraft of the German defense Ministry proposed to create a modern fighter-interceptor. Research conducted a year later, the firm “Heinkel” and “Messerschmitt”, showed that for a fighter with a high supersonic speed will require a new, extra-long runway.
This project began with specification E6/41, dated November 1941 In her Ministry of aviation industry of great Britain has offered the firm “de Havilland air craft company” to explore the issues of creating a jet fighter and engine for it. By that time, the company proactively developed an experimental twin-boom DH’s car.99. It was a single-engine monoplane of all-metal construction with a tricycle landing gear with nose wheel. The development of the engine in April 1941 did the firm “Halford”, headed by Frank Halford, simplifying the design of the turbojet engine with centrifugal compressor and through the location of the combustion chamber between the compressor and the turbine.
The weakness of the Navy of the USSR in the prewar years, tried to compensate by creating flying cruisers – multi-engined and heavily armed seaplane, able to deal with both surface and underwater ships, ground targets, and engage in mine production. As a result, in July 1931, the air force issued TSAGI reference for the development of seaplane MK-1 (ANT-22) with a lifting capacity of six tons. The plane had to fly at a speed of 300 km/h and have a radius of 1000 km. the Defensive armament was raised from four to five machine guns and two or three guns.
April 23, 1968 carrier rocket 11А511 was launched into orbit a new spacecraft 7K-OK, called the “Union”. The ship was piloted by pilot-cosmonaut, hero of the Soviet Union Vladimir Komarov. During the flight revealed a lot of failures due to the imperfections of design, what was the reason for the reduction program. On April 24th, during the descent from orbit, the crash occurred — refused recovery system of the lander. He was broken from hitting the ground, and an astronaut, unfortunately, died. It was the first victim of manned spaceflight.
During the Second world war, 15 oil refineries of Romania gave Germany more than 7% of petroleum products supplied dependent countries and satellites. The aircraft long-range and frontline aviation periodically attacked the oil-bearing regions of Romania. However, the transportation artery connecting them with the port of Constanta, continued to operate. The most vulnerable were considered section of the pipeline laid on the bottom tier of Chernovetskogo bridge over the Danube river.
