Progress and regress of world aviation.


Not so long ago had a chance to ask about the progress or, on the contrary, degrades, the modern world of aviation, and, faced with this problem was quite by accident, and therefore had to start the argument on the facts available.



No matter how modern, reliable and effective the flight characteristics of aircraft and helicopters produced in the last decade were, it is most likely to be erroneous to state that the world aviation is on the path of progress. Yes, of course, modern aircraft, helicopters and other aircraft have a number of qualities that one could only dream about hundreds of years ago, but in fact, even the appearance of aircraft, their shape and design principles did not change at all, although to a certain extent it is possible Consider progress that modern airliners are able to move not only at high speeds, but also at great distances, overcoming thousands of kilometers in just hours, not weeks, taking into account dozens of intermediate landings. In addition, the safety of air travel has significantly increased, and if earlier the plane crash could not have surprised anyone, since the first technique was clearly far from perfect, it is much safer today to fly by plane than to drive a car, although the risk is definitely there And partially manifested, sacrificing hundreds of passengers.



Without going into details, is it possible to note any innovations that have appeared in aviation over the past 10-15 years, there certainly are, however, in essence, these are nothing more than improvements to already existing units, parts, mechanisms and equipment, in a fundamental way not different from the original ones? In addition, it should be noted that aviation itself, if you try to look at it from the outside, practically does not develop - new aircraft appear extremely rarely, and only a few companies are engaged in the design of new ones, while in the 40s - 70s, for Dozens of planes appeared every year, and even taking into account more or less large ones, their number increased from year to year. What do we have today? Bunk passenger seats? Virtual reality helmets for comfortable air travel? Aircraft models differing only in passenger capacity?

Of course, in military aviation, this picture is much more colorful and promising that in other observed always, however, the civil aviation is very much sums up in this regard.



It follows from all this that world aviation is not going through the best of times, and, moreover, some experts are sure that the regression is only increasing every year and it is quite possible, with the departure of the last generation of great aircraft designers, this area can completely sink into oblivion, , we are not talking about hundreds of years, but only about a couple of tens.


Kostyuchenko Yuriy specifically for

Dear Moderator! I beg you not to send my comment in the cost center and ask to print according rules. my idea of ​​a cost center miraculously appeared at Eurocopter. It lacked to this idea in the hands of our enemies - the United States.

Kostyuchenko Yuriy raised an interesting question about the progress and regress of world aviation, including helicopters.

Old-timers of aviation remember the flights of the ML Mil helicopter of the transverse B-12 scheme. “The son of an outstanding aircraft designer, a representative of his firm in Europe, Sergei Sikorsky, wrote:“ Before an engineering achievement such as the B-12 helicopter, you can only take off your hat ... This helicopter is one of a kind and will be used to perform unique operations. I mean expeditions to the Arctic or the search for oil fields. The helicopter will replace the railroad in places where no man's foot has yet set foot. " "Science and Life", No. 8, 1998

And started the exploration of the Arctic ... helicopters Mi-26: «crews Mi-26 restore Arctic military town
March 24 2014
Three hours flight from Tiksi to Boiler, most took place over the Arctic Ocean, - said the commander of the Mi-26 Alexei Pavlov. "
Stored kopiyaPokazat More from site
A "engine consumes up to 3100 kg of fuel per hour, and flight hour cost is about 600 thousand April 7th, 2013»

It should be understood that prior to summer season there was no refueling and drove it (MI-26) is not advertising 20t payload that the output is a solid ruin the State.
In our media only and read about Mi-26: «reliability, efficiency, versatility and unique." The Indians did not agree: "They (the Mi-26) obsolete, consume too much fuel, road maintenance, and obtain spare parts for them is not so easy."
"For the second time in recent years American helicopters are superior both technically and economically, Russian Machines", - writes the Indian press. "

In this case the opponent was American helicopter longitudinal scheme "larvae", who lost and Mi-26. "Larvae" in the last modernization of transporting cargo by weight of an equal. For comparison: the Mi-26 weighs 28t, but the maximum load = 20t. Difference!
Designers cost center for a long time it is time to move on to designing helicopters transverse schemes which have experience in In-12, but do not repeat in-12 with its big drag, and perform a modern aircraft with minimal drag and flight speed of more than 300k / h. I believe that the most beneficial in this regard will be the next version of the transverse circuit helicopter:
wings on propulsion engines of the same one D-136 + wing on each rotor gearbox +, i.e. conventional helicopter lateral scheme, but the chassis must be designed fixed gear, but with minimal drag, because at strong frosts work any mechanism is given with difficulty. In Ni-26 compared with B-12 chassis with less resistance, but this requirement is also not suitable for high-speed helicopter.
The tail assembly is necessary to perform a vysokoraspolozhennymi stabilizers, which set the tractor propeller (propeller). On the keel installed capacity of the engine, for example, in 3000l.s., Buyout through shafts and transmits rotation to the pulling stabilizing screws. Those. the output will rotorcraft with a cruising speed of more than 300k / h. Again you need to payload he took in relation to the Mi-26 not only in advertising prior to 20t, but could actually carry a load in the "Three-hour flight from Tiksi to Boiler", then he will be profitable!
And what is necessary for this? And it is necessary stabilizers with pulling propellers perform turning on 90grad., So when hovering and taking off in a helicopter tail rotor screws help in creating traction rotorcraft. As speed is increased after takeoff stabilizers occupy a horizontal position. And their responsibility for more traction rotorcraft go to stabilizers.
So AB-17 screw weighs 145kg and provides a starting traction = 2270kg the engine power = 1500l.s.
For the two screws it will be more traction rotor 2270kg x 2 = 4540kg. and minus the weight of the motor screws in 1t. and that 3500kg - as additional fuel with the help of the tail rotor rotorcraft can take to increase the flight range without sacrificing payload, but at the same time have a much greater cruising speed!

With regard to helicopters, the US is building a high-speed coaxial helicopter Sikorsky "S-97 Raider". They do not have experience in this scheme, so they "stamped" on the spot. Our company "Kamov" since 2007 year has real projects of modern high-speed helicopters coaxial Ka-92 and longitudinal scheme Ka-102, but under different pretexts they are hindered by "Helicopters of Russia". And in the 2001 year the Kamovians offered the Ka-32-10 helicopter project on the basis of Ka-32, so it was not an expensive project, but there were no "customers" for it. Its modern aerodynamic fuselage has internal dimensions similar to the Mi-8 helicopter and "The new machine will be offered to customers at a price of 3,8-4,5 million dollars:
But the Mi-38 thirty years at public expense under construction, under construction and will not be built, "Mi-38 1,1 get another billion rubles from the state budget Fri, 25 / 09 / 2015 - 11: 43 | », and the customer had" Helicopters of Russia ".
Compare official data on projects helicopters of a class:
coaxial Ka-32-10AG and Mi -171A2 with tail rotor, in which the same engines VC-2500.
- Ka-10AG: "Increasing duty to 5500 kg inside the cabin and to 7000 kg on external sling"
- Mi -171A2: "Inside the cargo compartment 4000 kg on external sling 5000 kg."

This shows that on-duty helicopter Mi-171A2 inferior helicopter Ka-32-10 / 11 almost 40%, which should be a priority in the design of search helicopters, but not in our country.
Also and speed characteristics, but Mi-171A2 out in a series, and Ka-32-10 not in sight!
