Competitions of different rank showed that as prototypes for the manufacture of contour models are used only a dozen types of aircraft. And to participate our aeromodelling circle in the next competition, it was decided to make a model rare prototype. Our choice fell on PIPER CAB, one of the most successful light aircraft, produced in mass quantities since the pre-war (1935).
For many years Hobbies of technical creativity as the main source of materials and machinery for me was a different sort of scrap yard. Out in my shed “migrated” all that seemed valuable to me, and was waiting for their application to varying design. Unclaimed gradually accumulated, and eventually the question arose: what to do with it? Would not go. Here and decided to maximize all these different glands in your new tractor. Design “Angara” started with a sketch drawing of the design. Then, after the detailed execution of working drawings, started construction. The result was, in my opinion, quite aesthetically pleasing, technologically advanced and reliable machine, with a reserve for possible future upgrades.
The subject of today’s article – geophysical rocket R-2A. In previous publications we described in detail the technology of making copies of R-1 and R-2. The same technology used to create the model of R-2A. Will not be superfluous once more to tell for those who have not read those numbers.
Model-a copy of the ballistic missile R-2
In 1951, took arms ballistic missile R-2 (product 8Ж38), created under the leadership of S. P. Korolev. Its performance characteristics were: missile launch weight of 20 to 300 kg, the maximum flight range is 576 km, mass of warhead – more than 1000 kg. R-2 to improve accuracy in lateral direction had a system of the frequency control with two antennas on the body, weight an untucked missiles – 4430 kg.
Simple, easily repaired, volatile, inexpensive… That’s only part of the requirements for training RC model aircraft. These requirements are fully satisfied “Trainer-RC” — RC plane engine with a working volume of 6.5 cm3 type of MDS or 0.S.MAX-40LA.
A few old boards, a little effort and prepared the composting bin. But not simple, and universal. The bottom of his elevated and tilted to the side flap with latch — matured compost itself will be unloaded in a filled bucket. And while he is maturing, on top of the zucchini grow, hanging down (I Read more…
On a conventional two-wheeled Bicycle much gear not to take, even if it is equipped with a trunk. Meanwhile, the need from owners of these machines frequently. It is therefore advisable to make to the bike trailer.On the construction of such a two-wheeled trailer said Zbigniew Hyun-nel and Andrew Fedoruk in the Polish magazine “Mlody TECHNIK”, article from which prepared this publication.
The Russo-Baltic wagon factory (RBVZ) became the leader of Russian automobile industry in the early XX century. Founded in 1874 in Riga, is a large engineering company produced steam and horse threshing machines, seeders, plows, stationary oil and kerosene combustion engines, passenger and freight cars, trams, artillery limbers, and, later, cars and airplanes designed by I. I. Sikorsky. By 1912 the territory of the company, has a capital of 9.6 million rubles, was already 20 acres, and fifty shops of the plant worked 553 of the machine, which worked 4,000 people.
