Few, probably, ever see a modern sailing ship. It is widely believed that in our age of powerful engines and high speeds boat the best place in sports or for training cadets of sea schools.
Under the terms of the competition model rockets must stay in the air for Some time, and it makes rocketmodeler to look for different Methods of forced landing. Very interesting designed and a mug of rocket and space modeling the pioneers of the town of Krasnozavodsk. It allows you to limit the time of flight depending on the conditions of the competition.
A distinctive feature of this model of rocket plane is turning the wing. It is set along the fuselage, which eliminates any possibility of the appearance of the spiral during takeoff.
A kind of triumphant decade, one of his model rockets notes flying club syut town of Elektrostal, in the Moscow region. Created rakotomalala and model-copy geophysical rocket-5V continuously improved, they successfully participated and won at the most prestigious competitions and Championships in the S7 category.
The simultaneous launching of multiple model rocket engines presents a great challenge for modelers. Existing methods of ignition have several disadvantages; Perekrest does not allow you to launch multiple missiles for a short time (as the products of combustion clogging the tubes, burn the ends, etc.), as currently practiced method of ignition with the banks is a danger of explosion engines because of the filling of channel MRD pyrotechnic compositions.
With the end of the Civil war in Russia and the formation of the Soviet Union began intensive development of commercial aviation. July 15, 1923, opened the first regular air line Moscow – Nizhny Novgorod. For three and a half months by air it was transported by 270 people. In the following year there was a line Odessa – Kharkov, Moscow – Kharkov, and others. The development of Civil aviation is objectively required the creation of a passenger aircraft. One of the developers of passenger “air carriers” was the aircraft factory No. 1, former “Dux”, where in 1925, the engineering team headed by H. H. Polikarpov, and A. A. Semenov established a five-plane PM-1.
With the proposal of developing a new Intercontinental ballistic missile operating on liquid oxygen and kerosene, and in 1958 was made by the Council of Chief designers. While its weight was not to exceed 100 tons, which is almost three times less than the starting mass of the rocket R-7 – the famous “seven”.
We offer parachute system for more than three years is used by Leningrad on models-copies of carrier rockets of space vehicles. Simplicity and reliability has contributed to our athletic victories. At the last all-Union competitions in Smolensk in 1971, this parachute system was equipped with our model-copies of spacecraft “Soyuz” in grades “K-3” and “K-4”.
Good motor sudomodel, as they say, will not spoil. Just where in the Russian province it? Because most of the available domestic microelectrophoresis focused on the use in children’s toys, unfit for use (without major modifications) in RC models. The structural simplicity of these engines is often at odds with the requirements of duration, resource and, most importantly, threatens the high level of noise that reduce the reliability of the instrument radio. Imported good-quality motors (alas!) prohibitively expensive.
The emblem of the Leningrad order of Lenin shipbuilding Institute — sailboat on the open book — a notice to all shipbuilders. Bold design solutions, the movement of the search inherent to the graduates of the oldest institutions of higher education have resulted in many ships and vessels of the national fleet, from the familiar to every commuter boats to giant nuclear-powered submarines.
