Work on Future Engine Techology was presented by CIAM at Helirussia 2018 , Posting in full for the work and technologies involved

CIAM PRESENTED PROSPECTS FOR THE DEVELOPMENT OF HELICOPTER ENGINES

https://www.aviaport.ru/news/2018/06/26/545147.html

At the 11th International Helicopter Industry Exhibition HeliRussia 2018, held in late May, the Round Table "The Present and Future of Engine Building for Helicopters" was held, at which Yuri Fokin, Head of the Small-Scale Gas Turbine Engine (MGTD) Department of the Central Institute of Aviation Motors (CIAM), was the keynote speaker. Below is a systematic presentation of his report.
Introduction

In the 1990-2000s, a dramatic situation developed in the domestic helicopter engine building, due to the fact that after the collapse of the USSR, Russia remained without serial production of helicopter engines, in particular, the main aircraft engine of the TV3-117 family, which was manufactured by Zaporizhzhya Motor Sich enterprise. In addition, for a long time, new domestic helicopter engines were not developed or commissioned. Some projects have been started, but have not been completed, for example, the RD-600 helicopter aircraft engine.

The lack of domestic aircraft engines led to the fact that almost all domestic developed and modified helicopters were used aircraft engines of foreign production. Helicopters Ka-226, Ka-226T, Ansat, Ansat-U, Ka-62, Mi-26 use foreign-made engines. Now we are considering the option of using a foreign engine on a promising medium-sized transport helicopter. Moreover, even on the Mi-38 medium-capacity helicopter, the installation of a foreign engine was originally planned, and only the supplier's refusal to supply engines to Russia forced domestic developers to create a Russian engine (TV7-117V). Today, after many years of discussion, the issue of developing the serial production of VK-2500 engines in Russia has been resolved.

What is done by the "United Engine-Building Corporation"


Since the beginning of this decade, the program of import substitution in helicopter engine construction was launched, within which a very significant amount of work was carried out. The main results can be considered the development of the serial production of the VK-2500 family engines in Russia. In addition to assembling the engines of the basic version entirely from domestic components, work was carried out to create deeply upgraded VK-2500P / PS engines, in particular, VK-2500PС-03 certified for the newest Mi-171A2 helicopter. The VK-2500PS engine is a modification of the VK-2500 engine with a new fully digital control system of the FADEC type. Now the state joint testing of another modification of the VK-2500 VK-2500P engine for the modernized Mi-28NM helicopter, which is in the stage of flight tests, is on the agenda now.

In addition, the helicopter engine TV7-117V for Mi-38 has been certified. The basic version was developed in the 1980s, but the engine was certified quite recently, the Certificate was obtained with certain limitations of the operational range. During 2018, the whole range of measures to expand the operational range within the framework of the Terms of Reference should be completed, Fokin added.

We consider the possibility of developing a PD-12V engine for perspective heavy helicopters and VK-800V for light helicopters. So on the basis of the gas generator of the dual-path engine PD-14, intended for the passenger-oriented MS-21 airplane, the PD-12V engine for heavy Mi-26 helicopters is being developed. As for VK-800, work is now under way on an aircraft engine version intended for use in the power unit of the L-410 aircraft. At the same time, the CIAM supports the resumption of work on the creation of a helicopter version of VK-800V.

Finally, work was started to shape the perspective helicopter engine. At present, the company "ODK-Klimov" forms proposals for a prospective engine under the "Prospective engine for helicopters" program, this project has not yet been examined by CIAM. But so far it is known that an aircraft engine will be offered in a larger class of power than TV7-117V, which exceeds the existing analogues in terms of manufacturability and specific mass.

Creation of advanced scientific and technical reserve


Creation of future aircraft engines is impossible without creation of advanced scientific and technical reserve (NTZ). The goals and programs of NTZ development are already defined. In accordance with the adopted program, prospective aircraft engines should have significantly better characteristics in comparison, for example,

The main directions of the development of helicopter aircraft engines


The specialists of CIAM developed seven main directions for the development of aircraft engines for prospective domestic helicopters

Also the task is to improve the methods of 3D-design.

To ensure these directions of work, the CIAM is developing a whole range of breakthrough technologies. Together with the enterprises of the branch, the institute implements a program called "Development of Technologies for Advanced MGTS and AAP", the aim of this program is the creation of eleven demonstrators of advanced technologies.

Demonstration "electric" MGTD;

1 High-speed reducer MGTD;
2 Nozzle apparatus turbine from KM;
3 Heat exchanger for MGTD "complex" cycle;
4 Combustion chamber MGTD with elements from CM;
5 Experimental single-stage pulp and paper mill
6 Experimental two-stage PPM;
7 High-speed stage of helicopter gearbox.
8 Demonstration turbo-compound aviation piston engine;
9 Demonstration MGTD on gas supports;
10 Demonstration rotary-piston engine.


In accordance with the program, in 2017, the planned design studies with conditional leveling for 2025 and 2035 technologies were performed, and in 2018-2019 it is planned to manufacture and test demonstrators.

To achieve the stated progress of the characteristics of helicopter engines, the CIAM defines a set of technologies that allow obtaining products of a given level of perfection. So to "Technologies 2025" are:


1 Two-stage pulp and paper mill;
2 Compact low-emission CS;
3 RK turbine type "Bliss";
4 Impeller of pulp and paper mill from KM;
5 Compressor casing from CM Cabinet of CS from CM;
6 KS Flare pipe from KM;
7 CA turbine from CM;
8 Hybrid bearings;
9 Electric drive of units;
10 Wireless sensors ACS;
11 HIPCs with remote access;
12 MGTD "complex" cycle with maintenance.


"Technology 2035" includes:


1 Uncooled RK turbines from KM;
2 Case details in MS from KM;
3 Uncooled oil supports;
4 Shafts from CM.

Austin, Nice technology road-map by a developer.

HAL should have their own version of such a road-map tailored to Indian needs.

How does pulp and paper mill tie in with helicopter engines unless they want to use the rotor ideas for the turbine design.

Really ?

what is it doing hovering above an active volcano ?

this might be a typo for the last zeroes....
the symbol for degree has been translated into a Zero... surely.

Requesting all BRFites for info, if any available on Zhi-10 Attack Helicopter for the following:
- any reliable info on the tech specs of the installed powerplant-
- Is the so called 'Wozhou (WZ)-9' only capable of a measly 1000 kW? Or is that just mis-information?
- Another source indicated that they are using a version of the Russian TV3-117 MT turboshafts (used on the early Mi-17).
- Option -3 : Is it MOST probably the following? - marketing statement from Safran dated 2014:
"Developed in 50/50 partnership with Avic Engine, Ardiden 3C was ground tested for the first time in Bordes (France) in November 2013. Named WZ16 in China, the 1,700 shaft horsepower class Ardiden 3C belongs to the Ardiden 3 engine family, dedicated to the 6 to 8 ton helicopter segment. Ardiden 3C/WZ16 has been selected to power Avicopter AC352, jointly developed with Airbus Helicopters.
The Ardiden 3C/WZ16 program is the result of a strong and long lasting cooperation between Turbomeca and Avic. Through this partnership, operators and aircraft manufacturers will benefit from the know-how and experience of two key players in the field of aircraft propulsion."

Good to see you here sir.

This is what I know, after the PT6 embargo, they used Motor Sich’s engines. Motor Sich helped them with the WZ-9. WZ-9 was obviously underpowered for a helicopter which was supposed to carry 16 ATGMs. They used to carry 8. But even that was face-saving. They did not fly with full fuel. They are supposedly using the WZ-16 (illegally, the reason they are so hush hush about it) now and developing a completely indegeneous engine in the background.

https://www.safran-helicopter-engines.c ... /wz16/wz16


WZ16 is the Chinese designation of the Ardiden 3C engine, jointly developed (50/50) by Safran Helicopter Engines with AVIC Engine. The WZ16 is fitted in the Chinese AC352, jointly developed by Avic Helicopter with Airbus Helicopters.

It was ground tested in France in November 2013. The engine will be certified by EASA under the designation Ardiden 3C, and by the Civil Aviation Administration of China (CAAC) under the designation WZ16.

The WZ16 is characterized by excellent reliability, low-cost maintenance (TBO 3,000 hours on entry-into-service and 5,000 hours once mature) and extremely low fuel consumption (at least ten per cent less than other engines in the same power range).

The Z-10 is a weak bird that was beaten by the Turkish T129. There was a thread on PDF of a PA pilot who flew the Z-10 for four years, including operations against their “terrorists.” So the Pakis vacillated for four years with a bird that came without political baggage and finally decided on one that did. The PRC would not be able to export the Z-10 with the Ardiden.

We’ll see if the Pakis can actually get the T129 now that Trump is embargoing Turkey.

From AW&ST

India To Buy 200 Ka-226T Helicopters

NEW DELHI—India is expected to formally sign a 210 billion rupee ($3 billion) agreement in October to buy 200 Ka-226T helicopters being developed by Indo Russian Helicopter Pvt Ltd (IRHL).

The technical configuration of the light utility helicopter has been finalized and OK’d by Indian authorities. The project is being implemented under an intergovernmental agreement signed in 2016, a defense ministry official said.

IRHL will soon submit a detailed a proposal to the Indian defense ministry for the purchase.

Russian Helicopter CEO Andrey Boginsky said the Indian defense ministry has extended the deadline for submitting the request for proposals (RFP) for the helicopters, which had earlier been set for Aug. 1.

India’s defense ministry issued an RFP in May to procure and co-produce the helicopters for the country’s army and air force.

The RFP said 135 helicopters would be purchased for the army and 65 for the Indian air force (IAF). The Kamov helicopters will replace aging Cheetah helos.

Russian Helicopter and HAL are crafting a detailed business plan that will identify the order of localization activities, size of investments from both parties, and preparation of the manufacturing site in India.

Boginsky says Russian Helicopter and its Russian suppliers have identified the time required for localization in India.

“Right now the four parties—which includes our company and our suppliers, HAL and potential suppliers in India—are having a dialogue regarding localization for various components, how ready those companies are (to take up localization works) in terms of site, workforce and technologies. So we are actively preparing to start the project even though the contract is not yet signed,” he said.

IRHL is considering involving Indian private companies in the localization program, as many of them have the necessary capabilities. The intergovernmental agreement has a clause for up to 50% localization of manufacturing.

The capital of the joint venture is estimated to be 300 million rupees, with HAL holding shares up to 50.5%. Russian Helicopter will hold 42.5% of the shares and the rest by Rosoboronexport.

The new facility at Tumakuru will be self-contained for production and maintenance of Light Utility Helicopters. The cost to cover initial establishment of the facility is expected to be around 20 billion rupees.

The Indian defense ministry official said the contract is expected to be signed in October during Russian President Vladimir Putin’s visit to New Delhi.

IRHL is expected to fulfill a requirement for more than 200 utility helicopters for the Indian armed forces. Under the agreement, the helicopters manufactured in India would also be exported to third countries.

The Ka-226T has a coaxial rotor system and a maximum takeoff weight of 3.4 tons. It is capable of carrying up to 1.5 tons of cargo or up to seven passengers for 600 km.

This should be a very easy task- localisation as Tatas are making shells for US helo manufacturers and the bird ix relativelu unsophisticated.We slso havr a history of making French helo engines under licence, so the Frenchies on the 226 would be another breeze.

The naval variant proposed/ offered by Kamov would be interesting to examine, it may be low priced but it has stiff competition from global majors.
