In the autumn of last year in Tashkent was held the second personal championship of the USSR on flying sport, which was attended by 53 athletes from almost all the Union republics of our country. According to the established tradition, the championship was played in three model grades — SE, S4D and Ѕ6А. The editorial Board appealed to the chief judge of competitions the master of sports V. S. ROZHKOV to comment on the results of the competition, to talk about the changes that are made to already existing design of rocket modeling championship winners — leading athletes of our country.
First of all about the winners of the championship. First prize winners in this steel V. Tarasov from Chelyabinsk (class Ѕ3А), A. Dalmatians from Tajikistan (class S4D) and Moskvich V. Kovalev (class B). It should be noted that the victory was given to the Champions in a hard and bitter struggle — in one of the competitions for each of the classes of rocket modeling not without additional rounds. And if the starts of classes and Ѕ3А Ѕ6А took only one additional round, in competition raketoplana (S4D) they had to carry three!
It should be noted that the championship allowed us to compare the engines of three types: serial and experienced domestic and manufactured in Bulgaria. Their characteristics were very similar, and failures of MRD at the start was much less than at the first championship. Of course, here said the experience has already been acquired by rakotomalala in the treatment of MRD.
Now the models with a parachute of the class Ѕ3А. First, a few words about the technical requirements. Start their weight should not exceed 100 g, the momentum of the engine — 2.5 n·s. the Maximum allowed flight time in the main stage — a 4 min. Flight depends on its duration.
The most attractive was the model of champion of the USSR Vladimir Tarasov. He’s one of the few used the case the minimum diameter is only slightly greater than the diameter of MRD (12.3 mm.) In such a cylinder section V. Tarasov managed also to put a parachute with a very large dome (800 mm)! Hence, the height of flight more than other models, and longer descent. The second advantage is particularly useful in the run when the weather tried to prevent athletes: colder, the wind picked up, and, of course, no “terms”. Interesting structure was the model of the athletes, mityureva and A. S. Ilyin: the hull of their rockets minimum diameter had a longitudinal connector. These characteristics could not affect the performance of performances, Mityurev A. won the silver medal, and S. Ilyin took the sixth place.
Speaking of raketoplana S4D, we note first of all that in them is, unfortunately, hard to find items technical search, its own design finds. Almost all participants spoke with a miniature hang gliders of the type “flying wing” and “duck”. And almost all models to varying degrees, copied raketoplana recognized leaders — members of the USSR team. But at first, this seems necessary, therefore, improving the techniques and tactics of participation in the competition. And yet, if the athlete focuses not only on today, we should look for new schemes to use their own technical solutions.
