In June 1990, Kiev stadium DOSAAF “the Seagull” for five days has become a kind of Baikonur. Here were the start of the eighth world championship on rocket and space models. Athletes from 11 countries played awards of the world championship in seven classes flying of model rockets.
First to the launch pad came athletes with raketoplana (class S4B). Of the 32 participants maximum time (180 s) in the first round showed only seven “missile”. And when in the second round, none of them managed to fly on “high” (240), it became clear that the competition in this class will be completed in the allotted three rounds. As a result, gaining 688 (180+216+292) points, the world champion in the class raketoplana became a Bulgarian athlete T. Drago. He is winner of the gold medal of the FAI. Silver award in A. rose (USA). The result — 642 (180+162+300) points. “Bronze” went to C Kalaru (CSFR), he has 609 (180+179+250) points. Speech by Soviet athletes in the list of successful can not be attributed: S. Ilyin (526 points) — 6th place, I. Shmatov (505 points) — 8th place and Kovalev (396 points) — the 13-th place.
Since the equipment of our “missile” is known, will focus on foreign. Everyone’s attention was attracted by raketoplana American team. In fact, their developer is a B. Belos — famous designer-rocketmodeler. The presented model — airplane diagrams prednisalone engines enclosed in the discharge container. The last pendant is “floating” type that allows to get rid of the errors in the selection of the thrust vector during the flight to the active site. Length of about 600 mm. Span elliptical wing 420 mm of Central chord of 76 mm, the area of 2,5 DM2. The surface of the stabilizer is 0.6 DM2, the keel — 0.15 DM2. The mass of the airframe 14 Main material of the model: balsa, carbon fiber, fiberglass, resin. To start apply perchlorate engines of Czechoslovakian manufacture with a weight of 6-7 g, and a time of about 5 s.
Bulgarian model “rocket” was built by “hard” schema “rocket plane.” But they have a wing stacked design, covered in Mylar film. There is a mechanism for rebalancing the airplane mode. Bulgarian raketoplana equipped with ailerons, giving a small rotation around the helix to the active site. A lot of models slightly more than 20 g.
Raketoplana Czechoslovak athletes made mostly of balsa and have the weight of the glider 17-19 g with a wingspan of about 370 mm and the length of 400-410 mm. For them is characterized by mechanization of the wing, and automatic rebalancing, supplemented by the device of forced landing. Models start on the engines momentum 5 N*s, an outer diameter of 10 mm.
