SKIING — IN THE AIR

In the third issue of our journal in 1968 published a description of the design of snake-gibralta for water skiers, created by the pioneer of this sport in the USSR — Alexander Casein. Over the years the enthusiasts of technical creativity — IV first skiers — produced a large number of these aircraft. Flying snake-gibralta for the boat or car for many has become a favorite form of recreation. There had also been a successful winter flying in the mountains. Muscovite M. Gokhberg, master of sports of water skiing, winter 1973/74 year was flying on a kite, accelerating on the ski slopes in the area Terskol in the Caucasus.

 

Today we introduce our readers with gibtelecom advanced type, which can be used, starting not only with water but with snow on a winter skiing, or even just running, if conditions permit areas (such flights are usually practiced in the area of sand dunes).

 

Foreign athletes will gibelet called “dragon”. He has been very widespread among skiers, which rise on it in air independently, speeding on the way down a smooth slope with a steepness of about 15-20° (Fig. 1) and with a winch or helicopter. Takeoff should be made strictly against the wind, otherwise the control gibtelecom difficult and there is a risk of tipping it in the air, the Second condition for flying off the slope — the presence of an open and quite spacious grounds at its base, necessary for planting.

 

Recently in the cinemas of our country was shown wide-screen color film titled “Happening in white”. It shows the flight of skiers towed to the snakes over the snow-covered peaks of the Alps — the spectacle is unforgettable and quite extraordinary. Unfortunately, the authors of the review did not explain how to perform such flights, and in the film, start the “Seleccion” is not shown.

 

 

Fig. 1. Flight of the “dragon” with the crackdown on skis:

 

1 — acceleration, angle of attack is minimal; 2 — takeoff the angle of attack increases the deviation of the forward trapezoid; 3 — free flight, the angle of attack is reduced and an optimal deviation trapezoid back; 4 — landing, the angle of attack increases vigorously deviation of a trapezoid forward to cushion the feet.

 

 

Fig. 2. Takeoff by mechanical traction:

 

1 — acceleration, angle of attack is minimal; 2 — takeoff the angle of attack increases the deviation of the trapezoid forward with a constant thrust, in flight on the tow angle is constant; 3 — flight in tow of the helicopter.

 

The uninitiated viewer the impression that they are flying on their own. In fact, the rise and the whole flight is made with the help of a helicopter at the speed of 55-60 km/h (Fig. 2). The possibility of uncoupling of the “dragon” from the tug of the tether, after which the skier can make free planning flight and landing at any convenient place. Some virtuosos manage to perform planning flights with spirals and reversals, and then sit exactly in the intended item at the sites of very limited size.
