25 Nov 1933 soared gird-X — the first Soviet experimental rocket with LRE (liquid rocket engine). It was created in the Gird under the direction of S. P. Korolev on the project and calculations of Friedrich Arturovich Tsander.
Catamaran-vetrohod with hybrid propulsion. Despite the almost complete power supply equipment heat engines, shipbuilders are still hoping to create a workable ship, driven by wind. Only the last decades appeared sailboats with automated staging, management and cleaning of sails, Verkade with rotary motors, sailboats with a rigid sail-wing and kite sail…
Each model airplane is a painstaking work of the designer, as well as hours of training on Assembly. Creating and gluing a model airplane, as a rule, requires a lot of time and attention, but this hobby allows you to experience unprecedented passion, pride and joy for hand-made model.
Offer simple design of gliders developed in the circle of experimental design. syut Kostroma. They are all made mostly of foam, but differ from each other in size, proportions, mass, manufacturing technology wing flight characteristics. Models are recommended for the manufacture of young modelers in the home, in group classes and the technology classes.
The idea of composite, or multi-stage rocket put forward by K. Tsiolkovsky in 1929. And on may 19, 1938 near Moscow for the first time in the world was launched two-stage rocket designed by I. A. Merkulov, one of the veterans of Gird.
— Key to start!
Rapidly running time. In everyday Affairs and concerns we often don’t notice this. Fade and erased in the memory a vivid and memorable dates of the event. But some of them become part of history.
The proposed model torpedo boat was built by students in the 5-6-grade in ship modeling circle of the Moscow city club of young sailors, rivermen and explorers. In both variants rezinomotornaya and two microelectrophoresis — miniature torpedo boat had good speed and stability on the course. The model is simple in manufacture, does not require scarce materials. Young modelers, speaking at the Moscow urban competitions, repeatedly won prizes.
The desire to build a model of a biplane under the existing engine MDS-6,5 KU initially led to the search for analogues. View magazines and catalogs helped to decide what I would like to see a future model. Original design prototype was a biplane DUO 40 of the company Graupner. The outline of this plane was simple and cute. Now it remained only to consider the design of the airplane.
