    The actual issue is bigger established companies getting itchy over HALs success with helicopters.

    Pilot error was the reason behind the crash of two of the four India-made Dhruv helicopters supplied to Ecuador, while the cause of the other two cannot be attributed to manufacturing defects, the government said Friday.

    The reason of crashes of other two Dhruv helicopters was indicated to be “human error” and “non-maintenance” by the Ecuadorean authorities. In a written reply to Lok Sabha, Minister of State for Defence Subhash Bhamre said the ‘Dhruvs’ exported to Ecuador have sustained a series of crashes.

    Out of seven Dhruv helicopters supplied to Ecuador, four have crashed during the period October 2009 to January 2015. Dhruv helicopters were operating normally until January 2015, he said, adding post crashes in January 2015, Ecuador has suspended operation of these choppers.

    Hindustan Aeronautics Limited (HAL), on its own, deputed its experts to Ecuador in each case of accident. The Ecuador government constituted Court of Inquiry (CoI) in each case and being the Original Equipment Manufacturer (OEM), HAL also participated in the CoI. “The Court of Inquiry reports which have been released by Ecuador government have concluded the cause of first two accidents as ‘Pilot Error’,” he said.

    Reports of two other Courts of Inquiry have not been released by the Ecuador government, citing confidentiality. However, from the Flight Data Recorder (FDR) records analysed by HAL as part of Court of Inquiry proceedings, the following causes of accidents have emerged — probable cause is PAO-–Pilot Associated Oscillation (human error) and in fourth case “failure of tail drive shaft attributed to maintenance lapse by Ecuadorian team”.

    Ecuador government has not formally communicated to HAL or its local representative in this regard. The Minister said in order to increase the export potential in global market, HAL has approached European Aviation Safety Agency (EASA) for certification of ALH Dhruv helicopter. Long Term Onsite Maintenance Support for 3-5 years will be proposed in future contracts, he said.

    That is a pike hit right on the head!:biggthumpup:

    The two engines are for taking the bird up to 25000 ft in Siachen, so not agreed to here. That was a poor shot:nono:

    Two engines would be extra weight, if it was altitude they could just build a more powerful engine.

    BENGALURU, India --- HAL has achieved the highest-ever turnover of Rs.17,406 crores ($2.58 billion—Ed.) for the financial year ending March 31, 2017. “It is business as usual for us, with the Company doing well on expected lines. We also contributed around Rs.800 crores to the Government exchequer by way of interim dividend. This is in addition to Rs. 162 crores paid to Government as dividend tax. The PBT stood at Rs.3,294 crores,” said Mr. T. Suvarna Raju, CMD, HAL.

    The company expects ‘Excellent’ MoU rating for the FY 2016-17 from the Government as it has met all the relevant parameters related to its performance. HAL’s total sales for the year 2015-16 stood at Rs.16,736 crores and the PBT was at Rs.3 288 crores.

    Some of the highlights of the FY 2016-17 included production of 12 Su-30 MKI aircraft in Phase-IV, 24 ALH, overhauling of 197 aircraft / helicopters, 473 engines and production of 178 new aero-structures.

    The Company received orders worth Rs. 21,000 crores ($3.1 billion) that included 12 Do-228 aircraft for the Indian Navy, 32 ALH for the Indian Navy and the Coast Guard and AL-31 FP engines for Su 30 MKI.

    The year also witnessed maiden flight of HTT-40 and LUH in addition to carriage trials of LCA with fixed air to air refueling probe.

    HAL will be ready to launch IPO by end of August: MD
    Published April 11, 2017
    SOURCE: MONEY CONTROL

    [​IMG]

    The long-awaited initial public offering (IPO) of Hindustan Aeronautics Limited (HAL) could finally see the light of day by the end of August, said Chairman and Managing Director T Suvarna Raju.

    Speaking to CNBC-TV18, Raju said the IPO of the state-owned aerospace and defence company has been delayed as it required some concessions as far as putting data in the public domain was concerned.

    “We will have to wait till the results of the past financial year are audited,” said Raju. “We should be ready (for the IPO) by July or August.”

    At the Aero India 2017 a couple of months ago, he had said progress that was made on identification of Book Running Lead Managers and preparation of draft red herring prospectus and that necessary documents were in place.

    Reports have long suggested that the company plans to divest 10% of its shareholding and go public, but it has been delayed for various reasons.

    EOI has gone out for outsourcing the manufacture and assembly of the reduction gear module assembly

    @Gessler @PARIKRAMA @Sancho @Hellfire @Agent_47 @MilSpec @Ankit Kumar 001 can you make sense of this for me:

    Proposed requirement schedule by HAL
    [​IMG]


    These are pretty vast numbers, so it's important to understand what a reduction gear module is (I have no idea), is 1 required per engine or 1 per helo? I assume the figures above include provision for spares also.


    Anyway it gives a good indication of the LCH's production cycle- from 2018-19 it will start to be churned out in a serious manner and will very quickly come up to full speed (only 2 years later). Impressive stuff.




    + anyway, here is highlighted what utility there is in having high degrees of commonality across different systems not to mention having domestically designed systems.


    ++ as of now there are no proposed ALH orders for beyond 2022, I do expect this to change (ALH will be in production until 2030 I am sure of it).

    The major thrust in ALH is for Rudra variants. With units getting operationalised in the Strike Corps, we are increasingly getting an integrated air component at the Corps level now.

    Expect further availability of Aviation assets at Corps level in next couple of years.

    AFAIK, choppers have only one gearbox and if there are two engines, they both connect to the one gearbox only.

    [​IMG]

    However, I too am confused as to what exactly they mean by "Reduction gear module". I believe it could mean either a set of or a single gear wheel...

    [​IMG]

    ...the numbers seem to make the most sense when we calculate them as 2 per helo (64+114 LCH = 356 gear modules as 2 per helo. 55 spares).

    Either way this is a great catch and shows how LCH production is planned to ramp up in the years to come!
