Interesting analysis of design principles and comparison with S-97
I wonder if this is not a two-step program. The new rotor tested on the modified Mi-24 could be applied "as of now" on new and even existing helicopters, increasing their speed 10-15%. And Mil could not be left out of the promising high-speed business. But Kamov's proposals look like they have much more potential for medium and long term IMHO...dino00 wrote:THE SOURCE TOLD ABOUT THE RUSSIAN PROJECT OF HIGH-SPEED HELICOPTER

Mil won!

Mil project is more conventional and easier to bring to serial production.
Also, test platform was able to achieve 400kph with standard rotor setup (no pusher propeller) which is same as S-97 Raider which uses coaxial rotor and pusher propeller. Production and maintenance advantages are huge.
It's also physically larger which means more payload and better transport version down the road.
This is no brainer.
In the fall of 2018, another image of the PSV project appeared along the coaxial scheme typical of Kamov’s helicopters. A distinctive feature of the car were the "aircraft wings". In the description of this helicopter, it was noted that having both blades and wings at the same time would allow it to reach speeds of up to 700 km / h, RIA Novosti reports.

In your quote the 700km/h is attributed to the Ka concept.They're also saying that the final design from Mil will allow the helicopter to fly up to 700km/h

If Mil have won then it explains why the unsuccessful Ka concept would be shown.
Ugh I really hope they're not saying this concept won

Because as discussed further up the thread its easy to make a CGI showing the pusher prop mainly pushing, in practice because its single-rotor the thrust is mostly diverted sideways distinctly inelegantlyWhy not?
Looks alright. Simple and doable.
I'm down with that, relatively minor upgrade for pretty significant performance improvement of a big existing fleetIt seems they are going to improve the existing fleet of Mil helicopters upgrading the rotors first

A small boost in speed, multiplied by a huge number of units, is a very good way of making a big impact on your global capability, hats off to that. But a helo based on the new Kamov principle, flying 700 km/h, would be a fundamentally different type or aircraft with greatly improved capacities... it should be developed too
I would rather think Eurocopter would like to have Kamov's coaxial rotor technology and unrivalled experience!magnumcromagnon wrote:Definately, also couldn't Kamov go the same way as the Eurocopter X3?
...With exception that it should have dual counter-props like the Tu-95, maybe explore placing couple small jet engines rated at 10,000 kgf each near the tail wing, even maybe adding thrust vectoring nozzles in a simplified capacity to them.

I'm curious, what do you find better in Eurocopter's proposal? Or conversely, what is wrong with Kamov's one? It may be a bluff after all, but I don't see the big problem with it except for maybe the reduction of hovering capabilities due to the wing. But other than that it is amazing. And it fits with previous statements (in 2017) from Kamov's chief designer about future helicopters being sleek, with internal weapons and flying 500-600 km/h. So I tend to believe this could be real
In turn, KB Kamov will continue to develop the sea helicopter "Lampa"
KAZAN, November 23. / Tass /. The Ministry of Defense of the Russian Federation chose the project of the Mile Design Bureau (KB) to create a promising high-speed combat helicopter, while the Kamov Design Bureau will continue to work on the development of the Minoga helicopter. The general director of the holding company "Helicopters of Russia" (part of the state corporation "Rostec") Andrei Boginsky told reporters on Friday.
"The customer, having considered all the proposed technical options from the point of view of readiness, scientific and technical groundwork, opportunities for cooperation, chose a solution that presupposes achieving speed in terms of the objectives of the [technical assignment] based on the Milev machine," he said
“We should not forget that Kamov is already doing the draft design of the“ Lamprey ”helicopter. The same project is already underway ... applications in certain conditions and primarily in the fleet, "added Boginsky.
As previously reported, during the Army 2017 forum, the Russian Ministry of Defense and the Moscow-based M.L. Mil Helicopter Plant signed a contract to carry out the Speed research project to develop a high-speed combat helicopter.
According to Andrei Boginsky, despite the fact that the contract for the development of BPV was signed with the Mil MVZ in the competition for the development of its appearance took two KB - Mil and Kamov. “In order to give our customer the opportunity to demonstrate the possibilities, both Mil and KB and Kamov’s KB inside the holding made a decision, agreed with the customer to have two KB participate in this work. Accordingly, about a dozen concepts were proposed for the customer to choose. scientific and technical councils, where the materials that were made by two design bureaus were considered, internal protection was first carried out and several projects were presented to the customer’s commission, including the Mil projects and the Kamo projects and "- he said.
The general director of the holding noted that the competition had demonstrated the readiness of the design bureaus to prove their competencies. "If there is a discussion, then there is competition. It’s bad that it comes out on such a public plane, and it’s not even a discussion, but someone’s monologue. So there is competition, there are competencies to substantiate or prove the point of view of “And the customer already chooses a more appropriate option,” added Boginsky, noting that he considers this a positive thing.
About development
Earlier it was reported about the development of a promising high-speed helicopter for the Ministry of Industry and Trade and the Ministry of Defense of Russia. Viktor Bondarev, who at that time held the position of commander-in-chief of the All-Union Military Space Forces of the Russian Federation, noted that the helicopter being developed in the interests of the Ministry of Defense would go into series from 2022 and be able to reach speeds of up to 500 km / h.

Mil Design Bureau to develop fast-speed combat helicopter for Russian Army
The helicopter may develop a speed of up to 500 km/h
KAZAN, November 23. /TASS/.
...
As was reported earlier, Russia’s Defense Ministry and the Moscow-based Mil Rotorcraft Factory signed a contract at the Army-2017 forum on the R&D work to develop a fast-speed combat helicopter.
Although the contract for developing a rotary-wing drone was signed with the Mil Rotorcraft Factory, both the Mil and the Kamov design bureaus took part in the tender for working out its design, Boginsky said.
"In order to give our customer a possibility to demonstrate the potential of both the Mil and Kamov Design Bureaus, we have made a decision within the Group and have agreed it with the customer that the two design bureaus should take part in this work. Correspondingly, about a dozen of concepts were offered to the customer to choose. Scientific and technical councils were held to examine the materials prepared by both design bureaus," Boginsky said.
The tender has demonstrated the readiness of both design bureaus to prove their competences, the chief executive said.
