Yo lo que celebro es que finalmente admitas que los problemas del Dhruv son reales y no producto de la estupidez de quien los señala.

Nunca he negado que hubieron problemas con los Dhruvs, como desarrollo, concuerdo contigo "problemas siempre hay", lo que dudo es que no los hayan resuelto, ni que el Dhruv sea un producto malo perse.
6.3.2 Avoidable expenditure in transporting defective helicopters for an air show
The Company transported five Dhruv helicopters for the exhibition when they were under investigation after the accident and bringing them back without participating in the air show resulted in an avoidable expenditure of Rs.4.94 crore.
Advance Light Helicopter (Dhruv) on its flight from Bangalore to Ranchi via Hyderabad on 12 November 2005, made a precautionary landing in an open field due to heavy tail rotor vibration. The pilot brought back the helicopter to Bangalore and delamination of the flex beam was suspected. In view of the early delamination, a rework scheme was evolved to enhance the flex beam capability by ‘capping’ using two layers of pre-preg glass cloths with hot cured. After rework the same Dhruv helicopter on its flight from Bangalore to Ranchi on 25 November 2005 force landed near Hyderabad. On the same day the Hindustan Aeronautics Limited (Company) grounded all the Dhruv helicopters pending investigation.
Audit scrutiny revealed that two days after grounding all Dhruv helicopters, the Company decided (27 November 2005) to transport five Dhruv helicopters to Malaysia and Thailand to participate in the LIMA♣ Exhibition 2005. Helicopters were transported (1 December 2005), to Malaysia on the assumption that the exact cause of the accident would be established by 3 December 2005. However, it was decided (5 December 2005) to recall the display team since the reason for the defective TRB could not be established. All the five helicopters were brought back after incurring an expenditure of Rs.4.42 crore. Thus, transporting defective helicopters to Malaysia for the air show pending investigation and back resulted in avoidable expenditure of Rs.4.94 crore (including Rs.52 lakh on exhibition).
The Management stated (August 2008) that in order to offset the negative publicity due to force landing incident and to build confidence it was decided to participate in the aerospace exhibition in Malaysia and Thailand. However, in the interest of safety, this was dispensed with. The reply of the Management was not convincing as the decision of the Company in transporting defective helicopters for an international air show exhibition when they were under investigation was imprudent, unsafe and might have eroded the confidence in the buyer instead of enhancing the image.
The matter was reported to the Ministry in June 2008; reply was awaited (November 2008).
CHAPTER II: MINISTRY OF DEFENCE
2.1 Procurement of Advanced Light Helicopter
40 Advanced Light Helicopters (ALHs) valuing Rs 1747 crore contracted with M/s HAL are being inducted with technological gaps which may impact operational preparedness of Army. Induction of another 105 ALHs valuing Rs 9490 crore with Shakti engine is unduly delayed. Alternative measures to improve performance of ALHs are yet to be put in place even after a decade of its development at a cost of Rs 2488 crore. Thus deinduction of old fleet of Cheetah and Chetak helicopters has been considerably delayed impacting the operational preparedness of Indian Army in forward high altitude areas.
Helicopters are used by the Army for reconnaissance, observation, aerial attack and transportation of troops and materials. The Army Aviation Corps presently uses Cheetah and Chetak helicopters, which have become overdue for replacement. The deinduction of these helicopters planned to be carried out by the 10 th Plan, was postponed to 12 th Plan for want of replacement. As early as in 1980, Army planned to acquire Advanced Light Helicopters (ALHs) to provide quick logistics and troop movement in the battle zone, besides enhanced surveillance capability. Weapon systems were also to be integrated into ALHs to configure them for the attack role.
In June 1984, Government approved a project for design and development of ALH by M/S Hindustan Aeronautics Limited, Bangalore (HAL) in collaboration with M/s Turbomeca, France, based on the Qualitative Requirements (QRs) of the Air Force. The project was completed in June 2001 at a cost of Rs 2487.99 crore, of which Army had borne a share of Rs 808.89 crore. In September 1995, Army projected a requirement of 99 helicopters to be inducted by 2007, which was subsequently reduced to 40 helicopters. The ALH initially produced under the Limited Series Production in 2001 had technical shortcomings and failed to meet the QRs. The ALH was not able to fly above 5000 metres though the Army’s requirement stipulated an ability to fly up to 6500 metres. This deficiency was because of the limitation of the B2 engine used in the ALHs. Also the vibration level of ALH was not within the acceptable limits. Despite the shortcomings, four ALHs were accepted by the Army and further order for eight placed in order to sustain the production lines of HAL. Waiver for ALH not meeting the QRs was granted by the RM in November 2001 as a one-time exception based on the following assurances given by HAL:
1. HAL would identify a more powerful engine to replace the B2 engine in order to meet the qualitative requirement.
2. HAL would try to improve the performance of B2 engine to meet the qualitative requirements.
3. Basic empty weight (BEW) of the helicopter would be reduced from 2550 kg to 2450 kg.
HAL undertook development of a more powerful engine “Shakti” in collaboration with M/s Turbomeca in order to replace the B2 engine. HAL however failed to overcome the shortcomings in the ALH even after five years as of December 2008. Army meanwhile ordered supply of another 28 ALHs in 2006. The inability of the ALHs to fly above 5000 metres was due to the inability of HAL to reduce the basic empty weight of the helicopter as had been assured to the Government.
Thus Army had to procure 40 ALHs valuing Rs 1746.88 crore despite these helicopters having technical shortcomings of not being able to fly above 5000 metres altitude. Contracts were signed with HAL in March 2006 for the above supply of 40 ALHs for the Army, at a total cost of Rs. 1746.88 crore. The delivery of all the 40 ALHs was to be completed by March 2007. Prior to signing of the contract, 16 ALHs were already supplied from December 2001 to March 2006. Up to March 2008, HAL could supply only 24 ALHs to Army, as against the 40 ALHs ordered for delivery by March 2007. Thus due to delay and inability of HAL to develop the ALH according to Army’s requirement, Army is saddled with 40 ALHs valuing Rs 1746.88 crore with technical shortcomings. Also Army is compelled to rely on the old fleet of single engine Cheetah and Chetak helicopters which are of more than 30 years old technology.
In December 2007, Ministry finalized another three contracts with M/s HAL for procurement of 105 ALHs, at a cost of Rs 9490.79 crore. These ALH were to be fitted with the newly developed Shakti engine. The delivery schedule for these three contracts was to commence from 200809 onwards provided the Shakti engine was evaluated by August 2008. Army Aviation (Maintenance Advisory Group) at HAL Bangalore stated in September 2008 that Shakti engine under development had deficiency in power and necessary improvements were underway. Therefore, it is not yet certain whether another 105 ALH ordered in December 2007 at the cost of Rs 9490.79 crore would be devoid of the shortcomings and meet the Army’s requirement.
Thus failure of the Army to acquire suitable ALHs timely has led to considerable delay in deinduction of old fleet of Cheetah and Chetak helicopters, which may impact operational preparedness of the Army adversely, especially in high altitude areas in forward locations. Ministry may ensure that the induction/deinduction plan of critical systems and aircraft is not allowed to suffer on account of serious slippages in adhering to the time schedule or quality requirements.
The case was referred to the Ministry in September 2008; their reply was awaited as of February 2009.

.- Claramente indica que dependerá de la recarga del aire.

Pero, aunque no es probable, es posible que Brasil gaste miles de millones de euros en un programa de 4 SSK sin estar equipados con AIP, y tienes razón no hay nada oficial al respecto.

Ecuatoriano, está muy claro en la publicidad que has puesto:

Propulsión: Diesel-eléctrica. (Luego de AIP, ni se nombra).

Brazil and France has signed an agreement that involves the construction of 4 diesel-electric submarines (SSK), plus assistance in developing and fielding the non-nuclear parts of 1 nuclear fast attack submarine (SSN). Key specifics, such as the presence or absence of Air Independent Propulsion technologies, have yet to be made public, but the terms of the agreement leave the possibility open. Reports regarding the submarine deal’s value have varied, but the budget is now set at almost EUR 7 billion.

Creo que Scorpene es solo question para que necessitamos dar un nombre al Submarino.
Saludos!
Mira que dices tonterías, cada vez que posteas en el FMG, ya no te basta con hacer el ridículo en el hilo del A-12, si no que también lo haces en éste:
Scorpene , es un nombre "registrado" (Trade Mark), por lo que no se le puede poner a ningún otro submarino, que no sea el que construye el consorcio formado por DCNS-NAVANTIA (al 50%),¿ te das cuenta de las tonterías que dices?.
Bueno como siempre , claro.
.- Saludos.
