The upgraded Ka-52M helicopter received new blades designed for the naval version of the Ka-52 Katran

The modernized attack helicopter Ka-52M, whose state tests have reached the finish line, in addition to new armor and protection, received new composite blades with heating elements that prevent them from icing. This was reported by a source in the Russian defense industry.

New composite blades with heating elements were developed for the naval version of the Ka-52K Katran helicopter, but after testing, it was decided to introduce them into the upgraded Ka-52M as well. The blades are fully composite, which excludes their destruction in case of minor damage. On aluminum and metal blades, damage leads to their further destruction.

A small change has been made to the blades for the Ka-52M helicopter. Inside them is a heating element, that is, an anti-icing system

- leads TASS source words.

Earlier it was reported that the Ka-52M received new armor and a new airborne defense system, a radar with AFAR, a VK-2500 engine, new aviation tires of increased wear resistance and new propeller blades. A new sighting and navigation system has been installed. The armament was unified with another rotorcraft - the Mi-28NM. The Ka-52M's arsenal includes the Hermes-A long-range missiles, the Whirlwind-M guided anti-tank missiles, and the LMUR light multi-purpose guided missile, also known as the 305 product.

The helicopter has already been tested in the NVO zone in Ukraine, and state tests are currently being completed. The manufacturer of Ka-52 helicopters announced the readiness of the lines for serial production of the upgraded machine.

The upgraded Ka-52M helicopter received new blades designed for the naval version of the Ka-52 Katran

What's the news?

New composite blades with heating elements were developed for the naval version of the Ka-52K Katran helicopter, but after testing, it was decided to introduce them into the upgraded Ka-52M as well.

Did you put other blades on the same bolts?

This is understandable, but why the hell did they put the blades in the headline?
Maybe they replaced the pedals too?

[Arkady007]

It is strange that such questions are asked in such a rank.
Written "... new composite blades with heating elements."
They took it to the heading, because they are composite.
How many countries can make load-bearing elements from composite materials? And how many of them can put heating elements on the composite?

You probably didn't realize that these are blades from the SAME helicopter!
They came up with and produced the NEWEST for the Ka-52M - this is stylistically clear and correct, but REMOVED from a neighboring car, then this is already different.

blades with heating elements

That is, before that, the blades of the anti-icing system did not have? Weird. On old helicopters (Mi-8, Mi-24) there are heating elements (corrugated nichrome tape, pressed into the front of the blade).

These titles are given here not for a great mind and not for victories over the enemy, but for the number of comments written, even if they are stupid.

And how many of them can put heating elements on the composite?

Only the leading edge is heated. In metal, it was rubber with conductive elements, glued to the "forehead" of the spar with a metal lining on top. It is not necessary to heat the blade, but only to melt the ice on the surface of the "forehead". It is divided into sections and the contacts are brought out to the current collector on the sleeve. The wires went through the hollow shaft of the gearbox. The spar itself is a metal hollow "pipe" with a flat back wall. To it were glued "sections" of about half a meter of aluminum "honeycombs" with sheathing on glue. Adjacent sections were separated by sealant-textolite inserts. This is so that the skin does not tear and does not warp when the blade is bent. Air was pumped inside the spar under slight pressure to control imperceptible cracks.
There were cases when sections were pulled out, there were holes in the spars from 7,62. This is a very reliable design. Only labor intensive. Plastic, I don't know. Probably cheaper to make. Anyway, if one blade is damaged, the whole set is changed - 5 pieces.

[vovochkarzhevsky]

The heating element is in the form of thin metal strips.
And since the nineties, no one has changed a set of blades, one at a time.

Well, in our time the country was richer. Or maybe they learned to do it more precisely. I do not know . Our kit was fitted, the blades were numbered, the balancing weights were installed. It remained to beat off the "coconusness".

[vovochkarzhevsky]

So I have been in aviation since the eighties.
But from experience I will say that the weight of the blades does not really matter. When the tip of one of the blades came off in flight on our Mi-24, only the noise of the propeller changed. Vibrations have not changed.

For illustration. On these screws, the NE is very clearly visible.

they are composite for the Ka-50 and Ka-52

For the first time in our helicopter industry, composite, multi-spar blades were used on the Ka-50. In case of combat damage, such a blade continues to work and can withstand up to three hits of 12 mm caliber.

I remembered the slogan of the Komsomol: "Give"!

[Skipper]

With such a triumph of Iranian loitering kamikaze drones, helicopters are not needed at all (well, this is exaggerating .... sarcasm). Expensive ... ineffective and dangerous for pilots and difficult. The drone launched - cheaply - effectively ... imperceptibly ... safely. Range and accuracy are on top.

[Siberian 66]

It’s probably not very correct about helicopters, but it’s true about attack jet and turboprop aviation. The whole world has come to this. The natives are still to be driven, yes, even propeller-driven attack aircraft are just right. And where there is air defense, Neither Rooks nor Thunderbolts have anything to do. Only BLPA.

[vovochkarzhevsky]

Well, well, on the same Mi-28 it takes in one of the variants of the BC 16 ATGMs and 40 NAR S-8.
Tell us how many UAVs, guidance stations and operators you need to have a similar effect as the Mi-28 with the indicated BC in the same time.
At the same time, keep in mind that a UAV is much easier to hit than a helicopter.

Damage on aluminum and metal blades

Strongly said, aluminum is no longer a metal ?????

[Bad_gr]

During the modernization of the Ka-52, they planned to change its locator (from Arbalet to AFAR CUTTER). But there is not a word about this in the current articles.
"Crossbow"

"CUTTER"

...... Serial Ka-52 helicopters, currently in service with Russia, use the Arbalet dual-band coherent-pulse radar station to detect targets. It provides reliable detection of ground objects such as "bridge" at a distance of up to 32 kilometers, and various air targets - at a distance of up to 15 kilometers.
_The new radar "Rezets" received a fixed active phased antenna array with 640 transceiver modules. The mass of the radar is 130 kilograms, 10 kilograms less than the "Crossbow". The radar station can detect bridge-type targets at a range of up to 100 kilometers, a destroyer-class ship at a distance of up to 150 kilometers, and air targets at a distance of up to 50 kilometers.
_In addition, the Rezets radar has the ability to detect helicopters in hover mode at a distance of up to 20 kilometers. Fixed targets are among the most difficult to detect with modern pulse radars, as several important parameters cannot be calculated for them, including speed and movement.

By the way, it is not clear why they do not use such a long-known method of reducing the thermal visibility of helicopters as spraying liquefied carbon dioxide or nitrogen into the output devices of engines.
Moreover, this system will not be used constantly, but where there is a threat of defeat by MANPADS.

[nikto-nikak]

Do you know the heat dissipation of engines? It is not difficult to estimate the mass of nitrogen carried.

[vovochkarzhevsky]

Not as much as you think. Especially if this is done through the EVA.

[TIR]

Why not create a single complex missile carrier helicopter + UAV reconnaissance and missile guidance. And for this UAV to be controlled by a helicopter armament operator. It would be possible for helicopters not even to enter the detection zone or hang below, hiding behind the folds of the terrain. Let's say, a group of helicopters took off from the rear airfield to the area of ​​the enemy's offensive, took a safe position, released the UAV from the external sling and waited for it to reconnoiter the targets and aim missiles at them from the group of helicopters. You can also aim at the laser beam. You can send 2-3 UAVs at once. But we need rockets, and what kind we have now and those that can fly 20-30 km. And an UAV is needed with a range of 500 km so that it can return to the airfield under its own power

Yeah, especially if you land with NARs from a roll-up. In the white light, like a pretty penny. And the drone is right on target. Half of the outskirts have already been dug up with such shooting. As for the ease of defeating a drone ... this is a statement on your conscience.
