It is hard to imagine the competition without rocketmodeler launches RC models. It is, along with the competitions models-copies, quite an interesting spectacle, including from a sporting point of view. Of course, impressive for the beauty of the start of the model rocket—glider with a rocket motor and control its flight using radio signals.
Competition for the duration of the flight rocket gliders include the single-stage runs any of the beetles of the RC of model rockets that return to earth in stable gliding flight supported by aerodynamic bearing surfaces. Model rocket plane needs to take off vertically or nearly vertically (within a cone with an angle of 60 degrees) without the use of aerodynamic lift. Not allowed in the engine compartment or container.
Currently, the category of radio controlled model raketoplana (S8) are divided into six classes, depending on the total impulse of the engine, the starting mass and wingspan. Young men compete and fly in three rounds class S8D the Requirements for models in this class are: impulse MRD—10,01 — 20,00 H.with; starting weight—not more than 300 g; the maximum flight time in a round is 6 minutes.
In class S8E/P are adults competing on the flight duration and precision landing on a platform the size of 10×50 meters. Technical requirements for models raketoplana in this class are: impulse MRD—20,01—40,0 N.c; starting weight—300 g; wingspan is more than 1100.
Interesting history of the development of radio controlled model raketoplana. In the first, the provisional Regulations of the competition in rocket-space models (1966), the word “radio” is, of course, is not mentioned. All models brought into one category.
The first time I saw in RC flying model rocket plane in 1978 at the 3rd world Championships in Bulgaria. The winner in the category of raketoplana (class S4D) was an American Harald Angren, the model of a rigid structure (plane of the diagram), equipped with a radio. It should be noted that in those days most of the athletes “fly” with the models is made according to the scheme proposed at the time, Francis, Rogallo. It was the aircraft with soft wing.
