COAXIAL ROTOR CHAMPION

COAXIAL General interest participants and experts of the past championship of Russia for sport flying showed to the model of the winner in the class of rotochutes (S9A) Mr. Voronenko. I must admit that in my many years of practice in the rocket modeling coaxial rotocut is an extraordinary event. I believe that this information will be of interest to readers of the journal “modelist-Konstruktor”.

BOARD AND SAILBOARD AND SAILTHE WIND IN THE CONTEXT OF
 
The sail of the windsurfer is not the only element that produces thrust, but “the wheel” for manoeuvring. The air flow at the surface and water has a lower speed than the wind at a height of, say, three meters. Therefore, the load on the sail (corresponding speed) are proportional to the height from the water level and each overlying section of the sail will receive a certain twist in relation to the underlying (Fig. 1A).

SUGGEST MODELERS ERFURT

SUGGEST MODELERS ERFURTIt seems that it does not intersect the path of the guys involved in designing the different kinds of models. And competitions are organized separately, and laboratories of its own, Avia – and ship-, auto – and aerospace modelers. But it is necessary to have someone appear more interesting novelty to emerge of a technical idea and it becomes the property of all. It happened with the advent of glass, of which the first avtomodelisty, and then the young shipbuilders began to mold the body and the body is Now this methodology successfully applied by the designers of aircraft models. Here’s how to do it modelers from the city of Erfurt.
