In the laboratory, missile and space modeling of the Moscow city Palace of children’s (youthful) creativity of the work on the creation of models-copies of the booster (PH) “Soyuz” was launched in 1984 with the arrival of the Chelyabinsk rakatomalala Alexander Left, while a student at the Moscow aviation Institute. In developing the model tried to take into account not only all the achievements in the construction of models-copies PH “Union”, created in different years domestic rakotomalala — S. Parnevik, V. Rozhkov, A. Klochkov, A. Korchagin, V. hohlovym and A. Bachey, but not to repeat the shortcomings of their designs.
To create the model took 1:50 scale to prototype as the most simple, allowing to fit in the layout of the nozzles of the Central unit are four serial model rocket engine MRD 5-3 with a diameter of 13 mm or 11 and get off mass, not beyond the limit set by the rules. The main material of the buildings chose the fiberglass, and frames for supporting the docking and undocking of certain parts of the model are aluminum and magnesium alloys.
After nine years of hard work on fine-tuning of the model A. Left in 1993 he won the European championship. Model-a copy of the first attempt has done a beautiful flight in a three-stage configuration, it is highly appreciated by the judges.
This was accompanied by work on a new version. The basis for it was a set of high-quality photos PH “Soyuz-2” with the spacecraft (SC) “Soyuz TM-12”. They were made by a photojournalist for TASS, the Soviet Pushkareva by order of the newly created Federation of flying sports of Russia with the assistance of the National flying club. Photography made it possible to develop drawings and make almost a perfect set of technical documentation on a specific prototype, as required by the rules the FAI Sporting code for space models and to start building a new model of a copy that was ready for the world Cup in 1994, the Revision was allowed, if necessary, to perform four-stage flight, with the division into twelve parts, according to the following cyclogram: start — 0 C; the side blocks — 1,5—1,8; reset the layout of the propulsion system of emergency rescue system (PS SAS) and fairing (TH) — 2,3—2,5; the launch of a model rocket engine (MRD) 3rd stage and the separation of the Central unit is 2.8—3, the ejection recovery system Central unit — 4,8—5; launch of MRD layout KK — 4,5—4,6 s; ejection of the recovery system 3-tier — 6,6—7; the separation of layout KK — 8,5—9.
The European championship of 1997, which took place at the First World air games and world Cup 1998 was again victorious. The successful flights made by the model A. allowed Left turn from three-time European champion and first to win the title of world champion. Seven-year statistics of the flight-models at the international competitions has confirmed the correctness of underlying design decisions, which allowed even in case of accident to avoid serious damages and to vary the composition and number of flight demonstrations depending on the results of the bench evaluation and the prevailing conditions of wrestling. The scheme of fastening and separation of the side units can be used on all models-copies of a prototype batch of the scheme.
Model-a copy of PH “Union” with the spacecraft “Soyuz TM-12” consists of a Central unit (CB) 2, four identical side blocks (BB) 1, adapter 3, 3 stage 4, 5 KK layout, the two halves of the fairing 6 and do mock CAC — 7. The entire model consists of twelve parts, each of which has its own system of salvation. Power source (battery) on-Board power supply located in the front compartment of KK layout. Side grid is carried out on gargrota and connects through the electrical compartments of the KK layout, 3rd stage, adapter and the Central Bank. To reset, start the engines of the 3rd stage layout and KK used electrosupply installed in the adapter and layout of KK, respectively. To stabilize the flight of the 3rd stage is provided by the unit drop-down stabilizer, and the flight 2nd stage regulator, console, which is installed on the housing of the Central Bank. During the powered flight phase of the 1st stage they are in the slots recessed into the hull BB.
The distribution of MRD by steps as follows: in four of the Central Bank of MRD (one 3 and three Wed 10-3); each BB one by one mrad A-3 or b-3, reduced to 3 N-s total impulse; one of MRD In-3-3 3-tier and one mrad A-3-3 in the layout of KK. The simultaneous launch of eight MRD side blocks and Central blocks is provided with Perekrestok. The engines of the Central Bank give commands to the flight demonstrations, In-3-0 gives fire a beam for triggering the pyrotechnic device, the shooting of the BB. The first and second Wed 10-3-0, by closing electrical contacts movable sleeves when triggered, batches of gunpowder, form the team to reset and start the engine of the 3rd stage. Third Wed 10-3-2, its linkage expelling charge ejects the recovery system of the Central Bank. To generate a desired sequence of the MRD flight In a 3-0 first Wed 1 0-3-0 modified to reduce the length of their work (by reducing the length of the solid propellant charge). The engines of the 3rd stage layout and QC to improve the reliability of their ignition deployme equipped with nozzles.
The Central block (CB) 2 consists of a body and a removable tail section. Three frame (upper 2.22, the average power of the lower 2.5 and 2.14) connect and centered between an upper cone 2.3, a housing with conical and cylindrical parts 2.6 and 2.2 of the inner tube, which serves as a parachute compartment. It is a labyrinth reusable wad 2.9 and 3.6 parachutes adapter and Central unit 2.7. To protect the cylindrical part of the thermal impact during the ejection recovery system, the gap between the inner tube and the cylinder filled with balsa 2.30. At the bottom of the cylinder are mounted four focus 2.33, which fix the engine compartment, and has four holes for the passage of the piston BB. In the holes of the upper frame fixed 2.22 snap ring that is bound through the attenuator chute 2.7.

On the cylindrical shell of the Central Bank, in mutually perpendicular planes at BB, four console mounted stabilizer 2.10, which is placed directly behind the console retainer bracket 2.12, tilted forward the supporting planes. The retaining bracket is formed by two cross-shaped articulated plates, passing through holes in the housing of the Central Bank.
Tail section (HO) is composed of three frames, top (pyrotechnic) 2.30, 2.33 and lower average 2.14, which unite and centered housing 2.15 and 2.16 four tube engines, located at the axes of the dummy nozzles. 2.33 average frame consists of a metal ring and the balsa wall 2.34. MRD installed in the tubes HO and the fixed pins 2.31. In the upper parts of the two tubes is located an electric contact with terminals of electrical connectors which are connected to the onboard grid. Docking and centering HO with the body of the Central Bank secured the landing shoulder of the upper 2.30 and 2.33 of the middle frames. At the top (pyrotechnic) the frame is made of four slots and four cylinders, arranged perpendicular to the axis of the frame. The grooves serve for the passage of thrust 2.32 Central Bank, which fix the position of the engine compartment when it is rotated relative to the housing. In this combined openings in the housing of the Central Bank with the cylinders of pyrotechnic frame. Also in the fireworks frame is made of a Central cavity with a sealed screw plug 2.28 and connected by openings in the cylinders and the blank pipe of the first engine. Upon completion of MRD In-3-0 serves fire a beam into the Central cavity. He ignites an additional charge of gunpowder, which sends the beam into the cylinders. From beam to ignite the pyrotechnic sample in 1.11 BB pistons inserted in the cylinders. The hot gas pushes the pistons of the cylinders, firing the BB. Reliability is achieved by selection of the diameter of the holes in the bulkhead pyrotechnic precluding rapid gas flow from one cylinder to another.
Design BB 1 is formed by housing 1.2 and the tail section. In the front of the case mounted to the cap 1.1, with a focus of 1.8, and the location of the pistons strengthened from the inside to medium frames 1.9. In the lower part of the housing is a connecting frame is 1.25, the design of which ensures quick Assembly of the tail section. The latter is formed by the housing 1.7, and two frames, upper and lower 1.23 1.26, and consists of two parts — a metal ring and the balsa wall 1.12. Both frames also serve for mounting two tubes 1.15, 1.17 (parallel to the axis of the block), also santaromana with a pair of dummy nozzles 1.24 unit located closer to the center. One of them is 1.17 mrad compartment, the other 1.15 a guide for a retractable parachute compartment 1.18 (VPO). He plugged the top with a tube 1.16, in which a pin 1.14, sliding along the guide grooves 1.3, cut parallel along the axis of both tubes. 1.13 spring fixed at one end over pin 1.14, and the other for the end of the tubing actuates the VPO, forcing him to move beyond the end of the block.
