The easiest way to cast him “into the ground” — in sand-clay the form obtained by pressing it to the plane of symmetry of the model Bulba, carved out of wood. Bulbs obtained from pairs of such castings, tied in a single whole with three or four screws-tapping screws.
The next stage of construction of the body — bonding of the frame members and the keel well, which under the wooden slats, plywood box and pitching well in the foam cut grooves, and all these details are fixed in the housing with epoxy glue.
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).
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
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.
It is no accident XII-IX century BC historians call the “dark ages”. During this period, the tribes inhabiting the Northern and Eastern coast of the Mediterranean sea, meeting face-to-face, marked the beginning of numerous clashes peoples. Ancient States were dissolved in the mass of the conquerors, and the free lands of the new colony. Art, and knowledge fell into decay, was perfected as a weapon. In the center of these events was Phoenicia, a city which has turned into a different camp. But not only the fear carried with them the conquerors, has never had the Phoenicians faced with a variety of designs and decoration of ships that washed up on their shores. This was the impetus for the development of shipbuilding. In the main shipyard in the Middle East actively adopt foreign experience, adapted it to new conditions.
Throwing model-polyopia su-24. The model is designed and manufactured in the laboratory aeromodelling Center for children and youth technical creativity of the city of Rybinsk for novice modelers. The prototype has become a modern supersonic bomber with variable geometry (sweep) of the wing su-24, standing in service with the Russian air force. The launch of such models always generate interest among club members, and spectators. And thanks to the simplicity of manufacturing the model of this jet was a great success at the country children’s centres.
Apparently, in the technical work appeared in the phenomenon that can be called bottle-modeling. The fact that modelers in different fields are increasingly used… plastic bottles. From these light and sturdy vessels, they made a great hull models of yachts and catamarans, compressed-air cylinders to drive the action of the compressed air motors air and car. Thin clear plastic was the ideal material for the manufacture of lamps for aircraft models.
History of rocketry in our country today is widely reported in the local media. In my opinion, it is interesting it is stated in the book “Rockets and people” – B. E. Chertok (Publishing house “RTSoft”, 2006) – a direct participant in the whole period of the birth of rocket and space technology. These books “pushed” our children-rocketmodeler to implement the idea: to recreate the models in the basic steps of creating missiles and combat shield of the Fatherland and the achievements in space technology. This project was a contribution of students in the Year of Russian cosmonautics and the 50th anniversary of space flight by Yuri Gagarin.
