Acrobatics in the pipe: aerodynamic sports future

The seventh kilometer Toksovo highway - still the wilderness, but the eye suddenly clinging to the unusual three-storey building rises above the gas station. The inscription on the building reads: "Aerodynamic FlyStation pipe". But this is not purged in a stream of model airplanes, missiles or high-speed vehicles. Here, people learn to fly like birds. And how to fly!

Wind tunnels from the end of the XIX century helped scientists and engineers to carry out various studies in the field of aerodynamics. However, as technology advances, it became clear that the horizontal pipe in some situations fail: test helicopters, parachutes and study the behavior of aircraft at disrupting the flow (in a spin) required vertical wind tunnels. The first such test tube became complex Vertical Spin Tunnel Laboratory at Memorial Aeronautics NACA them. Langley (now the Research Center of NASA them. Langley) in Hampton, Virginia, built in 1940. In 1941, a vertical wind tunnel T-105 appeared in Zhukovsky near Moscow, and in 1945 - based on the Wright-Patterson in Dayton, Ohio.

Last pipe became famous due to the fact that it is in it, the first flight of a man, was taken up by the air flow. In 1964 he passed the test parachute systems for "Apollo" program, the work was almost around the clock, and one day near two o'clock in the morning when everyone was relaxed and carefree, one of the testers, Jack Tiffany, suddenly said: "Run-ka this thing, I try to fly. " As he later recalled Tiffany, "gizmo launched, and I flew."

Air ballet

Olga Bakulin, Flystation instructor, at this year's Wind Games 2016 competition in Spain won in the category of "freestyle" in fourth place on set and second place in the music round. Her performance reminiscent of classical ballet, but in three dimensions. "The lack of warm clothing and parachute opens much greater freedom of movement. Freefall during a real parachute jump lasts only 40 seconds, and in the pipe can fly for hours. Lack of strict time limits allows you to turn the same into a complete freestyle highly artistic performance as a ballet or figure skating. "

The Canadian invention

For the general public the joy of flying without wings and other accessories (not including the pipe itself) has been available since 1978, when the Canadian inventor Jean St. Germain patented design of the vertical wind tunnel and built in Canada Aerodium complex (legend has it that he did this in order to explain to their children what a free flight). The flow in the pipe created propeller, which rotates the engine from the aircraft DC-3 and passed through the center of the tube, and the edges was a "dead zone". Later, there were two important improvements. Firstly, SkyVenture company has patented the design of the pipe in which the flow passed through the entire cross section of "wall to wall" (wall to wall). From a kerosene engine with a propeller moved to several propellers electrically, the flow from which is then boiled and "compacted" by reducing the cross section, forming a nearly laminar flow. Second, in 2004, it was patented and began to spread a new type of pipe - air circulation in a closed circuit. This led to even greater laminar flow even in large diameter pipes (which in current models can be up to 5 m) and the possibility to place the pipe is completely inside the premises, which is especially important in cold climates. Since the pipe with air recirculation is widely spread around the world.

Their job - pipe

FlyStation pipe (www.flystation.net) built by the German company Indoor Skydiving Germany (it is second only to SkyVenture largest company of this kind). The air stream circulates in a closed circuit, flight zone having a diameter of 4, 3 and a height of 17 m. The air from the four propellers driven by four motors 1 total capacity of 25 MW, is reduced into a single stream and "sealed" by narrowing the passage area of ​​the flight. "The air flow cools the engine itself is heated to a comfortable temperature above 20 ° C even in the most severe cold, - says technical director FlyStation Roman Merkulov. - Some of the heat is necessary to reset, for this design in a special leaflet provided through which warm air escapes and cold exterior gets inside. "

To flow in the tube was laminar as possible (although the walls and in the opening of turbulence can not be avoided), after installing the tube is adapted, individually adjusting each step of the propeller. According to Roman Merkulov, German experts assessed the laminar flow on their own feelings, just flying in the tunnel. Flow characteristics are dependent on temperature and humidity: warmer air is less dense and less "hold", it is necessary to increase the flow rate, which increases the turbulence - all these athletes have to take into account. Other tubes have different constructions and performance when athletes in competition requires pre-flight 30-40 minutes to get used to the features of "the guest field" - set the desired flow rate and turbulence explore space.

The main postures

Basis bodyflight - the ability to hold the static air in the basic postures: lying on his stomach, lying on his back, his head up and his head down. This sport does not require excessive development of any muscle groups (a general physical training), important balance, coordination of movements and stretching. Therefore, the age limit this sport is not - they can do with four years.

With a parachute and without

The main clients of the first vertical pipes were paratroopers rehearsed flight skills in a free fall. "It's pretty close to parachuting, - says Olga Bakulina FlyStation instructor, master of sports in freestyle skydiving (and several other disciplines). - Same freestyle and freeflying, and group acrobatics, if the pipe size allows. But in real warm clothes jumping and parachute shackle freedom of movement. Time in the tube is not particularly limited, moreover, there are guidelines and, unlike real jumps, you can even see a small horizontal displacement. This allows you to work a very high coordination of movements - literally down to the centimeter. So now training in the pipe are almost obligatory part of the preparation of any high-class athlete-parachutist. But not limited to flights to the pipe became an independent sports discipline - bodyflight. And this discipline is very beautiful, unique synthesis of figure skating, rhythmic gymnastics, yoga, and dance - and all this in the air ".

on the skin

The outer airlock door closed slowly behind me. When it comes to an end, the inner door also opened slowly. At this point, I understand why you need to give me earplugs: falls on me busy hum. I fall into an open aperture in the inner glass "glass", but do not have time to touch the mesh floor - the wind blowing from the bottom picks me. The striker's face air felt not like a strong wind, and as a solid table, and I was with some difficulty balancing on it, caved in and stretching out his arms and legs as I was taught at the briefing. Leonid Volkov holds my grips, specially made for such cases on the back of firm overalls, but by making sure that I'm in control, let go in free flight. Chatted a bit in the stream and bumping a couple of times on the glass wall of the pipe, I awkwardly slip out into the doorway and leave the flight zone. Our photographer shows me a thumbs - they say, cool summer! - and I was filled with pride. But she quickly disappears, when my instructor, motioned to the operator of the pipe to the increased flow rate, starts his speech. I have the full impression that he just manages gravity, turning it in the right direction. When I tell him about it after the speech, Leonid replied: "Since my childhood I wanted to be a pilot, but it did not work out. And I still fly. Albeit without wings! ". I ask the question about the use of flight skills in a pipe in normal life, and he laughs: "Of course! Apart from the general physical training and development, and now I can run against the wind! ".

Games in the pipe

As part of the Wind Games, there are several categories that can be divided into two types: technical and artistic. Formation Skydiving (Four - 4-way) refers to technical, full analogue skydiving discipline, and to the artistic - the dynamics and freestyle. Dynamics - is a mandatory command (speed passage of the three-dimensional track at a time) and an arbitrary artistic program. Freestyle - is an individual arbitrary program.

Duration

As part of the Wind Games, each participant in the category of "freestyle" is due to speak in three rounds with any program (two for one minute and one two-minute music). output allowed in the first two rounds of the time frame of not more than 2 seconds, otherwise subject to penalty points. Some speakers use timers or music on headphones (allowed), while others rely on their internal clocks, and rehearsed the program.

The evaluation criteria

During Wind Games athletes performances are evaluated based on different criteria - technicality, artistic presentation. The jury is composed of representatives of various artistic sports such as figure skating and dancing, as well as skydiving freestyle.

Profile

Name: Leonid Volkov Occupation: Instructor Flystation Achievements: won first place in the category "freestyle" on Wind Games 2016 competition in Spain

"I got into the flight in the wind tunnel in the summer of 2012 just for fun. After that, I jump a few times with a parachute, but realized it was not mine - too much time spent on routine and expectations, and I'm a man impatient. For the year to master the basic skills, then I got bored, and I started fooling around and come up with new elements. When the first time decided to take part in the competition, brilliantly failed - finished last. Then another spoke many times in the past year was cut to timing 1-minute rounds, earning a penalty points. But this year everything went flawlessly. My girlfriend helped me with the choreography and choice of music - and here's the result. "
