British scientists have discovered that a well-washed screw allows you to save up to 33,3% of fuel. This is not like neftekorporatsiyam, so airlines practicing washing screws, according to camouflage, they say - so have to run. However, it is clear that the engine is started is _do_ washing screws, therefore, the theory according to which the propeller wash is required to run the engine, does not hold water.

Do not worry, mate. For here's a +1 in compensation;)

Rating not put, as in itself an interesting video. But, dear author, why did you mislead people by saying that this washer screws, eh? It's just starting. Either hot or the atmospheric pressure is low, or both, and more.

And more detail? I, as a man far from the launch of the AI-24, did not understand why water poured over them:)

If the launch takes place in the heat or on a mountain airfield, in conditions of high temperature and low density air mass flow of air through the engine during the startup process does not provide the excess of the available capacity of the turbine over the needs of power (compressor + screw). Lack of air mass flow engine tries to compensate for fuel, leading to an unsustainable rise in temperature gases. Unfortunately I do not remember, whether the ART-35 (simplified - limiting gas temperature) in the startup process. If yes, then by limiting the temperature of the turbine it does not develop sufficient power for the promotion of the rotor. If not, then there is the risk of exceeding the permissible temperature in excess of that Nizzam do. Whatever it was, running in such conditions can not. Hanging the stream of water to the engine, we enable the compressor to suck not just air, but heavy, so to speak, air, zatyazhelenny water. As result - mass flow of air in the process of launching enough to run without exceeding the temperature. And then at idle the water is no longer so necessary, because the engine went out on the equilibrium regime, when the power turbine is equal to the required capacity of the compressor and the propeller. Here's how something like that)) is too abstruse, huh? I can try to explain more in detail and simple. But this lichku

No, normal. A hundred times better than a "we have always run;)

Sorry, wrong turns. ART-35 on Tu-134 costs. On "Anton" also exists, but is called in some other way

It seems there it is called ART-24

That's interesting. Fulcrum83 - thanks for the explanation.

mad that ... weighted air .... it is just corrosion, if it is normal obsnyat then decreases only the amount of energy required to rotate the screw ... its like pokruchivayut.

It is weighted, as you say. And do not believe it, but when watering required power screw even higher. But only slightly. More importantly, the increase in available power turbines exceed the needs of the compressor and screw. And of corrosion. Have you ever turbine blades or nozzle pretty day's work saw the engine? Or, worse still, the combustion chamber inside? No? So, everything that affects them - a gas corrosion. And she let them in any case is striking.

Funny. After washing, once in flight?
