Un défaut du système de contrôle a provoqué la destruction par incendie d'une turbine à gaz de la nouvelle frégate russe "Admiral Gorshkov"

Un défaut du système de contrôle a provoqué la destruction par incendie d'une turbine à gaz de la nouvelle frégate russe "Admiral Gorshkov" | Newsletter navale | Scoop.it

The Central Naval Portal (CNP) has learned that an accident involving an engine on the new frigate "Admiral Flota Gorshkov", built at Northern Shipyard for the Russian Navy, was caused by the failure of a control system.
A CNP journalist learned from the Saturn Scientific Production Association, which is performing a survey and subsequent repairs of the engine, that the primary theory behind the failure was abnormal performance of the control system which led to the engine being flooded with fuel, after which it caught fire.
The fact that the engine on the Russian Project 22350 frigate "Admiral Gorshkov" required repairs was reported on December 29, 2014. On December 17, Northern Shipyard announced it was accepting bids for a 24-million-ruble contract for disassembling and surveying the ship's gas turbine engine.
According to a Saturn official, an assessment of the loss and inspection of the damaged engine pieces will last until March 2015 as company workers are not familiar with the engine's design. It is too early to announce when repairs will be completed and when fully operational engine pieces will be available.
The accident theory has been confirmed by another CNP source within the shipbuilding industry who has information about the accident. "The fuel pump did not shut off in time. There was a surge, and blades in the engine were damaged by the fire. The turbine has been removed and shipped to Rybinsk (location of Saturn Scientific Production Association - ed.) for repairs," the source said, noting that this occurred in September 2014.
Additionally, similar information has been reported by yet another knowledgeable shipbuilding industry source. He said that the control system failure could have been the result of a design error. "The turbine needs to undergo capital repairs; the blades were damaged by the fire. The problem was with the control system's performance. It was, most likely, a design error," he explained.
This opinion is shared by a Northern Shipyard employee. "The control system malfunctioned even though it functioned normally prior to this," the company specialist noted.
The design of the frigate engine's control system is Avrora Scientific Production Association Concern. Avrora informed CNP that the customer has not contacted the company regarding any complaints resulting from the mishap and pointed out that talking about the causes of the mishap can only be done after an official conclusion is made by experts.
Northern Shipyard's press office claims that there have been and currently are no problems with the ship or its equipment. "Our position is very simple. 'Gorshkov' completed the first phase of testing. And that's our position," stated the press office, adding that during the sea trials, the ship demonstrated specified numbers in accordance with technical specifications.
The fire-damaged M90FR gas turbine engine was developed and built at Saturn Scientific Production Association in cooperation with the Ukrainian company Zorya-MashProyekt. The Ukrainian company's press office told CNP that it had not heard about any problem with the Russian ship's engine and that no one had consulted the company regarding repairs.
Afterwards, CNP learned that the frigate's damaged engine was replaced with a duplicate engine from another ship of the same class - "Admiral Flota Kasatonov", which is also being built at Northern Shipyard. This was done in order to not delay factory sea trials of "Gorshkov".

Today, November 18, the newest frigate of project 22350 "Admiral Gorshkov", built on the St. Petersburg shipyard of "Severnaya Verf" for the Northern Fleet, the first left Kronstadt in the Gulf of Finland, where a marine landfill Leningrad naval base of the Baltic Fleet will be factory sea trials.Told the head of the department of information support of the press service of the Western Military Region for the Baltic Fleet Captain 2nd Rank V. Matveev

During the first phase will be checked ZHI driving performance of the ship, the work of the main power plant, ship systems and devices. In particular, the operation of the power plant, the steering system, auxiliary machinery, means of communication, detection and navigation, anchor gear. There will also be fast, maneuverable and vibration tests of the ship. In addition to the crew on board the frigates are more than 200 specialists from different departments of the manufacturer, experts from the industry, as well as contractors.

Factory performance trials are one of the essential stages of completing the construction process of any ship and conducted in order to verify the conditions of navigation in its systems and mechanisms for compliance with the approved specifications, diagrams, technical descriptions and instructions ekspluatatsii.Zakladka lead ship of the project 22350 - "Fleet Admiral Gorshkov "was held February 1, 2006 at the St. Petersburg shipyard" Severnaya Verf ".

Project 22350 frigates are typical ships construction with continuous superstructure made using composite materials based on polyvinyl chloride and carbon fibers (composite materials provide a reduction in the secondary radar field of the ship by absorption and scattering of radio waves). Physical fields frigate minimized. Thanks to the original architecture of the superstructure and the use of composite materials ("stealth") reduced the effective dissipation surface ship, which reduces its radar and optical visibility.

Bientôt des canons allégés pour la marine russe

Bientôt des canons allégés pour la marine russe | Newsletter navale | Scoop.it

Un canon quatre fois plus léger que les versions existantes ? C’est le défi que doit relever le bureau d'étude Ametist, qui s'est attaqué à l'élaboration du nouveau système d'artillerie naval allégé Kartaun-Puma. Ces nouveaux canons seront installés sur les navires légers, ce qui permettra à ces derniers d'afficher les performances des bâtiments lourds, écrit mardi le quotidien Izvestia.

Iouri Gladkikh, directeur général adjoint d'Ametist, a déclaré que le poids du dispositif a pu être réduit grâce aux matériaux composites.

"Nous sommes en train de concevoir un complexe réunissant le canon et le système de contrôle des munitions. Le canon précédent était double et pesait 97 tonnes. Le nouveau est simple et ne pèse que 24 tonnes grâce à l'utilisation de nouvelles solutions techniques et de nouveaux éléments, notamment des matériaux composites", précise Iouri Gladkikh.

Ce futur complexe se distingue des canons actuels de 130 mm par un système unifié de contrôle de tir, compatible non seulement avec tous les canons d'artillerie navals mais aussi avec le système côtier Bereg.

"Contrairement aux anciens systèmes, le nouveau dispositif est universel, c’est-à-dire qu’il peut s’adapter à tous les calibres et toutes les armes d'artillerie de la marine. Auparavant, chaque calibre nécessitait son propre système de contrôle. Demain nous pourrons donc réduire le nombre de systèmes et de mécanismes, permettant de réduire le coût de l’ensemble de contrôler des armes de 30 et de 130 mm à la fois", détaille Iouri Gladkikh.

Tout navire prévu pour artilleur pourra être doté de ce nouveau système mais il sera installé en priorité sur les frégates du projet 22350 comme Amiral Kassatonov et Amiral Golovko.

"Toute notre activité s’est concentrée sur la réduction du poids afin que ce système puisse être installé sur des navires ayant un tirant d'eau plus faible. Jusqu’ici le système ne pouvait être installé que sur les navires de 6 000-7 000 tonnes de tirant, alors qu'aujourd'hui les bâtiments de 2 000 tonnes de tirant pourront être équipés. Cela améliorera nos capacités offensives contre des cibles côtières et maritimes - dont des navires avec un tirant d'eau plus élevé", remarque Iouri Gladkikh.

Kartaun-Puma s’appuie sur les résultats d’anciennes recherches : le complexe inclura un système de contrôle de tir Puma, le canon fera environ 12 m de haut et 7 à 8 m de long. De même que le canon précédent Armat, l'artillerie sera capable d'éliminer grâce à lui une cible aérienne, terrestre ou maritime.

"La portée du tir pourrait bientôt être multipliée par 1,5 ou 2 par rapport aux performances actuelles. L'efficacité doublera également : la fréquence de tir du canon dépassera 30 tirs à la minute. On s'attend à une hausse de fiabilité de 50% et à l'augmentation de la vitesse de réaction jusqu'à 2 secondes. Seulement trois hommes au lieu de six seront nécessaires pour contrôler le nouveau canon", souligne Iouri Gladkikh.

Le système sera capable de tirer jusqu'à épuisement des munitions – les munitions du

Kartaun-Puma seront équivalentes à la capacité de chargement de la soute à munitions d'un navire, ce qui est impossible pour tout autre analogue étranger. Kartaun-Puma pourra tirer des munitions à fragmentation, sol-air et tout autre obus de calibre 130 mm, y compris des missiles guidés.

"Auparavant, le rechargement des munitions se faisait de la même manière que sur un fusil AK. Aujourd'hui nous disposons d'un système sophistiqué d'automatisation des mécanismes du canon, notamment pour le chargement des munitions SAP 192-M. Il sera possible de tirer sans interruption jusqu'à l'épuisement de toutes les munitions avec un choix automatique du type de munitions – par exemple nous pourrons changer un obus à fragmentation par un missile sol-air en un clin d'œil.

De plus, nous possédons une munition unitaire de ce calibre, ce qui est également un avantage par rapport à d'autres pays", explique Iouri Gladkikh.

Le système en question sera prêt début 2015. En 2013-2014, le bureau d'étude Ametist recevra près de 19 millions d'euros pour sa conception Et c'est la compagnie MZ Arsenal qui sera chargée de la production du complexe d'artillerie Kartaun-Puma de 130 mm.

Key Points
  • The first four of six Admiral Gorshkov-class frigates under contract with Severnaya Verf are slated for the Russian Navy's Northern Fleet
  • The timetable for completing the third and fourth ships may stretch thanks to loss of access to Ukrainian-produced gas turbine engines

The build status of the Russian Navy's third- and fourth-in-class Project 22350 Admiral Gorshkov-class frigates may be delayed as Russia contends with sourcing an indigenous propulsion plant supplier following Ukraine's ban on military exports to Russia.

The lead vessel Admiral Gorshkov and second-in-class Admiral Kasatonov are powered by two M90FR gas turbines designed and built by Zorya-Mashproekt in Ukraine.
