AVIÓN DE ENTRENAMIENTO HINDÚ VOLARÁ CON MOTORES RUSOS




Hindustan Aeronautics Limited
comenzará en Mayo los ensayos de su nuevo entrenador dotaddo de motores Al-55I
rusos.



El avión es denominado Intermediate Jet Trainer ( IJT ). Ha sido diseñado como
sustituto del Kiran como entrenador medio. La IAF ha realizado un pedido inicial de doce
aviones.



El IJT dispone de un avanzado cockpit digital, asientos cero cero, una célula
diseñada para 10000 horas de vuelo y un mantenimiento fácil. Puede transportar
una tonelada de armas en soportes externos.



El motor IJT ha sido diseñado específicamente para la IAF por la empresa rusa
Saturn. Hal producirá este motor bajo licencia.



La IAF podría
llegar a encargar hasta 200 IJT para sustituir a los actuales 250 Kiran.

Ajap, si el L-15 no cuadra y el Yak-130 no esta disponible o es muy caro, este seria una opcion interesante

Indian Army Gets its First Armoured Regiment of MBT Arjun

After 35 years of troubled development, India’s indigenously-designed Arjun tank has finally entered regimental service with the Indian Army.


Indian Army Gets its First Armoured Regiment of MBT Arjun

History of sorts was made today as the Indian Army proudly equipped itself with the first Armoured Regiment of indigenously built Main Battle Tank, Arjun. The development marks the fruition of 35 years of research in self-reliance by dedicated Indian scientists against all odds.

16 tanks (cumulative 45 Arjun tanks) were handed over to Lt. Gen. D. Bhardwaj, DGMF, towards formation of the 1st Arjun regiment by Shri S. Chandrasekar, Addl. DGOF (AV) and flagged-off by Dr. A. Sivathanu Pillai, Chief Controller, Research & Development & Distinguished Scientist, DRDO, at a function in Avadi today.

MBT Arjun is the state-of-art main battle tank designed and developed by Combat Vehicles Research and Development Establishment (CVRDE), Avadi along with other DRDO and industrial partners.

MBT Arjun is provided with excellent mobility, superior fire power and protection and the features are quite comparable to contemporary world tanks. The Kanchan armour, hydro-pneumatic suspension, armament system, Integrated Fire Detection & Suppression System, system engineering and system integration of complex weapon platforms are some of the significant indigenous technologies of Arjun, developed by DRDO labs.

Initially, 12 prototypes were developed during 1983 to 1990 and they were subjected to field trials of more than 20,000 kms and 1100 rounds. Based on user feedback 15 pre-production vehicles were developed during 1990 to 1995 and they were subjected to field trials of more than 70,000 kms and 8,000 rounds.

After the satisfactory trials, Army placed an indent initially for 15 limited series production in Nov 1997 and cumulatively 124 in Mar 2000. The development of Arjun was carried out in a number of stages and evaluation through extensive field trials. After satisfactory performance, Army placed an indent for the full complement of 124 MBT Arjun in Mar 2000.

As there was a long gap from the R&D phase to production phase from 1993 to 2000, problems related to re-establishing production lines and vendor sources and resolving overseas issues like technology denial in view of Pokhran testing, change over and mergers of OEMS for the critical items, delayed initial commencement of production.

In order to meet the production requirement, additional infrastructure facilities and machine tools were established at HVF, Avadi and Ordnance Factory, Medak. However, the first pilot batch of production tanks was handed over to Army on 7th August 2004 in the presence of the then Defence Minister Shri. Pranab Mukherjee.

During subsequent production, Army insisted upon the demonstration of medium fording capabilities of MBT Arjun. Both CVRDE and HVF continuously worked on war footing, to meet the stringent requirement of medium fording to a height of 2.1m in water with preparation time of 30 minutes as retro-fitment solution and demonstrated successfully to Defence Minister Shri A. K. Antony and other dignitaries on 2nd July 2007.

Subsequently, the production tanks were incorporated with all medium fording modifications and the next batch of nine tanks were handed over by Sep 2007.

Meanwhile, Army carried out the Accelerated Usage Cum Reliability Trials (AUCRT) in 5 phases on two tanks from Nov 2007 to Aug 2008 covering more than 8000 km and 800 rounds of firing in each tank. AUCRT is required for assessing the spares requirement for the entire life of the tank besides evaluation of reliability of tank.

Each phase consists of 1000kms run and 100EFC (Approx. 160 rounds of APFSDS and HESH – primary and secondary rounds) over a temperature range of -5° to 50° C. One of the main issues during AUCRT trials was the failure of the bearings of transmission of M/s RENK, Germany, due to rise in lube oil temperature. However, this was immediately solved by modifying the software during AUCRT itself and the efficacy of the software was proved for more than 4000kms.

However a comprehensive solution of modifying the bearing assembly by providing a special coating was carried out to take care of the temperature problem and the retrofit of bearing assembly being carried out in all the tanks.

The outcome of AUCRT trials raised the confidence levels of the users over the reliability and endurance of MBT Arjun and they confirmed that the overall performance of the MBT Arjun during the stringent AUCRT trials was satisfactory and cleared the production tanks with minor modifications suggested during AUCRT, for induction. Both CVRDE and HVF along with DGQA agencies worked out methodologies to introduce all AUCRT modifications within shortest time frame and the next batch of 17 tanks were handed over to Army by 3rd March 2009.

As suggested by Army after AUCRT trials, Arjun tanks were subjected to rigorous trials and assessment by a third party audit (an internationally reputed tank manufacturer). After the extensive evaluation, the reputed tank manufacturer confirmed that the MBT Arjun is an excellent tank with very good mobility and fire power characteristics suitable for Indian desert. They also added inputs such as quality auditing, production procedures and refined calibration procedures for further enhancing the performance of MBT Arjun.

DRDO will be incorporating all these inputs in the next regiment of 62 tanks for handing over to Army before March 2010 as desired by the Army.

The regiment of 45 tanks will be subjected to a conversion training and field practice for a period of 3 months. Thereafter, the Army is planning to conduct a comparative trial with T-90 tanks in Oct/Nov 2009 to assess the operational deployment role of the tanks.

The present batch of 124 tanks will be delivered by Mar 2010.

PRIMER TANQUE T-90 SALDRA DE LA FABRICA INDIA A FINALES DE MES
Categoria: Ejercito - 10-08-2009 07:52

Después de un retraso de un año, el primer tanque T-90 fabricado en la India bajo licencia realizará su roll out fuera el próximo 24 de agosto, dijo un funcionario del ministerio de defensa. La producción bajo licencia de los tanques se ha recomenzado solamente después que el estancamiento de la transferencia de tecnología de Rusia fue resuelto. Después de que la preocupación expresada por el establecimiento indio sobre los retrasos en la ejecución de los varios contratos de defensa, incluyendo los tanques T-90, Rusia haya tranquilizado a la India que la entrega ahora estará según el cronograma previsto. Los primeros 50 tanques T-90 saldrán de producción muy pronto, dijo el funcionario. El retraso en la fabricación del tanque principal de batalla Arjun y de la decisión de Pakistán para comprar el T-80 a Ucrania, incitó a la India a solicitar 310 tanques T-90 en el 2001. De éstos, 186 kits fueron montados en la fábrica pesada de vehículos en Avadi, cerca de Chennai. Un acuerdo también fue firmado para la producción bajo licencia de otros 1.000 tanques T-90. Esto, sin embargo, debió ser retrasado por la renuencia de Rusia a transferir la tecnología, incitando a la India comprar otros 300 tanques de Rusia el año pasado. Sin embargo, la producción localizada de los tanques no había comenzado hasta 2008.
