    Singaporean Defence Minister hails the Tejas as 'excellent'

    Singaporean Defence Minister hails Tejas fighter jet as excellent

    KALAIKUNDA (WB): Singapore Defence Minister Ng Eng Hen today hailed India's indigenously-built multi-role light combat aircraft Tejas as "very very capable".

    As the first civilian foreigner to fly on Tejas, Ng took a half-an-hour flight in the two-seater plane piloted by Air Vice Marshal A P Singh at the Kalaikunda airbase here.

    "It is a very very capable plane," Ng told reporters here after flying on Tejas.

    Hailing Tejas as "very impressive", Ng said, Ng said, "This is the reason why our air force trains with your air force. Pilots are superb, planes are pretty good."

    Praising Air Vice Marshal Singh as a "superbly confident and supremely professional" pilot, Ng said he felt as if he was riding a car and not flying in a fighter aircraft.

    "In fact the plane ride was so smooth that despite the G-turns and manoeuvres, I managed to even take some selfies," Ng said.

    Singh, who flew Tejas, is the project director of the National Flight Test Centre -- Aeronautical Development Agency.

    Asked whether Singapore is interested in buying the Tejas fighter aircraft, the minister said he was not a pilot and it was up to the technical people to take a call on it.

    Indian defence sources, however, said Singapore has evinced interest in Tejas.

    During the Bahrain air show where Tejas aircraft was showcased, some Middle Eastern countries had also shown interest, the defence sources said.

    Two Tejas aircraft were flown in here from Bangalore so that the Singapore defence minister can have a look at the aircraft.
    ..

    The Singapore defence minister is scheduled to meet his Indian counterpart Nirmala Sitharaman in Delhi tomorrow.

      ADA responds to the reports on the IAF being unhappy with the Tejas

      IAF not unhappy with Tejas- ADA scientists

      KOLKATA: Senior scientists of Aeronautical Development Agency (ADA) on Tuesday said IAF isn't unhappy with the performance of Tejas but wants more variety. There were reports a few days ago of IAF brass pushing for imports rather than settling for advanced versions of Tejas.

      "The Tejas is a light aircraft that has limitations of carrying capacity and endurance. But it has achieved its role as the best aircraft in its class. It has also successfully fired the latest beyond visual range (BVR) missiles. The IAF wants more variety. All the aircraft in its inventory can't be light. The IAF requires all kinds and that doesn't mean it isn't satisfied with the performance of Tejas," said ADA director Girish S Deodhare.


      "The Tejas is a state-of-the-art platform while F-16s are of 1970 vintage. Several countries in West Asia have also expressed interest in in Tejas," another senior official said.

        "Senior scientists of Aeronautical Development Agency (ADA) on Tuesday said IAF isn't unhappy with the performance of Tejas but wants more variety."

        More variety? What does that mean - we want a squadron of Gripen, another of F-16, another of FA-50 and a few more other types? Nonsense to me. If Tejas does the business (which IAF should know by now), it does the business. If not, it doesn't. Can any informed person explain to me why ADA says that IAF wants "variety"?

          Pay attention to what's written. It is clearly explained: variety is for a range of capabilities (heavier airframe).

            Very interesting video made by a BRF member. It shows a superimposed flight display comparison of a Tejas Mk1 with a Gripen C.

                          Some updates on the Naval LCA and future naval carrier aviation plans.

                          We continue to LCA Navy project. Our share of the budget for LCA was 40%, over INR 600 crores. Paying 40% for LCA Mk2, over INR 300 crores. I need a Dec based fighter by 2020. LCA Navy is nowhere on the horizon. It is underpowered. - Admiral Lanba
                          https://twitter.com/statuses/936488138532425728


                          "I need a deck based combat capable fighter by 2020 for IAC I, in present state, LCA Navy cannot be operated from deck" - Admiral Lanba
                          https://twitter.com/statuses/936489229911179264


                          As and when DRDO and ADA develop a deck based fighter we are happy to induct it. - Admiral Lanba
                          https://twitter.com/statuses/936488638820552705


                          Don't foresee budget problems with 57 carrier borne fighters. We have fixed form and fit of IAC2, conventionally powered, CATOBAR, through deck carrier. - Admiral Lanba
                          https://twitter.com/statuses/936486373812469760
                          The 57 CBMRF isn't just for IAC-2, INS Vishal as previously thought. Some of these acs are also meant for INS Vikrant. Admiral Lanba said he needs acs for IAC-1 before 2020.

                          According to IR of BRF, SP-5 is going to fly in a few days. And HAL may deliver SP-8 before the end of this year. I am eager to see whether SP-7 has the indigenous NAL supplied radar dome or the Cobham supplied one.

                            I doubt they would get the 57 aircraft any time before 2025 , Even the Rafale outright purchase comes with first aircraft coming after 3 years of signing the agreement.

                            Irrespective of what the Chief says on financial issue , I doubt financially the IN can afford 57 aircraft of twin engine class , more like 15 would be a good figure. They cannot even get approval for ASW chopper for past 5 years or a MCVC these things are more urgently needed for operational POV

                            Admirals should stop wasting their time by crystal ball gazing for 57 aircraft and instead induct Naval Tejas as is today and improve gradually its capability post its operationally debut and Look at Servicibility of Mig-29K by opting for PBL type arrangement with guaranteed uptimes like we do for French Rafales at a cost. It is better to be practical then crystal ball gaze for a service that has the lowest budget of the 3 service.

                            Some one in MOD should tell those Pipe Smoking Admirals that A bird in the hand is worth two in the bush

                              SP-5 had some issues that caused a delay in its first flight. It was the first production Tejas Mk1 from the new line that earlier was used as the Kiran hangar. But yes, it has been mentioned a few times that it's first flight is imminent.

                              I wasn't aware of SP-8 flying before the end of the year. What's your source? That would then mean 1 SP per month, which means HAL would have met its target to supply the IAF with 11 Tejas Mk1s before the end of financial year 2017.

                                Some updates.

                                - SP-8,9,10 are in the equipping stage in the final assembly hangar. Very soon they will be joined by SP-11 and SP-12.

                                - SP-5 which is from the second production line is expected to have its first flight before the end of this month.

                                - V Sridharan, the previous executive director of Tejas division expects the annual production rate to reach 16 by mid 2018. He expects the build rate to reach 20 there after since HAL has begun outsourcing all the structural assemblies, fuselage blocks and wings, sheet metal parts, pipings to the private industry.

                                -The standard of preparation hasn't been finalized yet despite the production of seven series produced aircraft. There has been 270 modifications in the aircraft since the attainment of IOC 2 status in Dec 13 as a result of concurrent engineering. This has adversely affected time scales.

                                - Interchangeability standards have been developed for the tools of all the 147 panels and 830 out of 942 pipelines within the production of first seven SP series aircraft itself which is a first for HAL.


                                http://english.mathrubhumi.com/mobil...1.2464308#menu


                                Bengaluru: Amidst the ongoing ‘controversy and confusion’ over whether the Indian Air Force (IAF) is keen to go ahead with the home-grown Light Combat Aircraft (LCA) Tejas programme beyond the first and second blocks of 20 each, the sixth series production variant from the hangars of Hindustan Aeronautics Limited (HAL) took to the skies for the first time sans any fanfare, recently.

                                The maiden flight of SP-7, the sixth out of the total 20 to be delivered in the Initial Operational Clearance (ICO) standards, took place on December 12 at the HAL airport here, with zero snags being reported by the pilot after completing the Profile-1 of the flight envelope.



                                Tejas SP-7 was piloted by Gp Capt K K Venugopal (Retd). With this, the IAF No 45 Squadron (Flying Daggers) would soon have half-a-dozon of Tejas platforms to operate with. Currently being raised in Bengaluru, the No 45 Squadron will eventually move to Air Force Station Sulur, near Coimbatore.


                                IAF is ramping up its infrastructure at AFS Sulur with modern hangars being reading to accommodate Tejas 16 fighters and four trainers, part of the first block of delivery from HAL.


                                SP-5 from Kiran hangar will join the party soon

                                The fifth Tejas series production platform SP-5, being built at the second production line established at the Aircraft Division by HAL, too will have its maiden flight soon. HAL converted the erstwhile Kiran hangar to set up this additional production line, which boasts of producing three aircraft per year, when fully operational.

                                V Sridharan, who retired as the Executive Director of LCA Division recently, says that Tejas platforms up to SP-10 are currently under equipping in Final Assembly Hangar.

                                “Very soon they will be followed by SP-11 and SP-12. Kudos to the entire Team of Tejas involved in the manufacturing activities for their untiring efforts in making this possible despite adverse criticism in the last three years, both in terms of quality and quantity,” says Sridharan.


                                Frequent modifications a concern

                                Interestingly, he says that the even after delivering six series production platforms by HAL, the Standard of Preparation (Build to Print Documents) have not been frozen, despite the IOC nod in December 2013.

                                “The introduction of more than 270 modifications after accordance of IOC, in the name of concurrent engineering is a potential source of introducing uncertainties during the production phase. This can affect time-lines on a regular basis. These changes even warrant design and manufacturing of new parts which results in delays. All these changes are introduced towards envisaged performance and system improvements as per the requirements of IAF,” says Sridharan, who has been credited with establishing the new LCA Division.

                                He says the LCA Division developed ICY (interchangeability) tools for all 147 panels and for 830 pipelines out of 934 pipelines within the build of first seven SP Tejas aircraft itself.

                                “This is a huge shift compared to any other projects in HAL, that too at such short span of time after the release of RSD (Release of Service Documents). Even now, only concept of replaceable pipes is existing in other projects. LCA has gone far ahead in the area of ICY compliance through the dedicated efforts of its tooling department,” claims Sridharan.

                                He says HAL, in an effort to further augment the production capacity, has outsourced all the major structural modules to private partners, including sub-assemblies, role equipment, pipelines, sheet metal part electrical looms and panels.

                                “This would enhance the production rate to 16 per year from the year 2019 onwards apart from developing an eco-system for manufacturing of a 4.5 generation fighter aircraft in India. This is likely to materialize by mid-2018 and thereafter, HAL would further be able to ramp up the production rate to 20 aircraft-plus every year,” adds Sridharan.

                                On the Final Operational Clearance (FOC) front, sources at Aeronautical Development Agency (ADA) say that the programme will complete all tasks mandated within 2018.

                                “There are only few more crucial test points to be achieved. Then there could be additional requirements. Hopefully, the FOC should be in place in the third quarter of 2018,” says a top scientist.

                                Currently, Tejas LSP-8 is optimising flight profiles with the in-flight refueling probe (IFR). The air-to-air refueling trials will begin early 2018. Four Tejas variants recently undertook night attack missions for the first time, as per the FOC schedule.
                                If HAL can produce 20 Tejas per annum, then it will be awesome not only for the IAF but also for HAL and MoD. Then we can say goodbye to the SE tender. It seems that the MII SE deal is currently in ICU and is inching slowly towards heaven. There hasn't been any news on this deal for the last two months. RFI hasn't been released yet.
                                Finally saner heads have prevailed in the MoD. With the scrapping of this deal, a lot of funds will be freed which can then be spent on the Tejas program and the Fgfa. It will reduce the logistical burden for the IAF since a new type wouldn't be introduced into service. The MoD it seems is going ahead with the acquisition of an additional batch of 36 Rafales. The nos can be even touch 80. The acquisition of additional Rafales for the airforce will give more impetus to the selection of Rafale for the 57 CBMRF for the Navy.

                                  Good to hear that HAL might meet its Tejas delivery target for 2016/2017 financial year.

                                  The acquisition of additional Rafales for the airforce will give more impetus to the selection of Rafale for the 57 CBMRF for the Navy.
                                  Isn't there a mismatch between lift width and Rafale wingspan? I have read of a proposal to detach Rafale wingtips in order to lift to/drop from the deck. I have also read comments to the effect that this would be impractical. Are detachable wingtips still on the cards and if so, how much would they likely add to the bill for 57 frames?

                                    They are still on the table and in fact are already detachable. (about 15 mins, testing included). However, not maintenance friendly to do that, i agree.

                                      In the recent interview of ACM Arup Raha by TOI on the Rafale deal, he revealed that the Indian Rafales will be different from the Ada ones in that they will have a more powerful radar with greater range, advanced ew suite and will be optimised for taking off from high altitude airfields.

                                      Now we are spending 1.7 billion € on customisation. Integration of Thales Topsight I HMDS, Spice 2000,1000 and 250 series, Astra Bvraam and other weapons won't cost much. Not more than a hundred million for weapons and HMDS integration. This leads to the question what is the rest of the sum for?

                                      Are we having that 14 kW RBE2AA that UAE once asked for but later this option was dropped.The peak power of RBE2AA is supposed to be 9.6 kW. This can be possible by increasing the peak power rating of each TRM, having a more efficient cooling system, new generation GaAs TRM which are smaller and thinner and by improving the module packaging.

                                      I assume we are having GaN TRM modules in our RBE2AA. GaN solid state emitters are already a part of Spectra jammers in F3R tranche. Ours spectra variant will include additional low jamming modes.

                                      As for the engine, the Fadec will be optimized for high altitude take off and landing and the Gas turbine starter as well APU will also be modded.

                                      We may have even gone for the uprated 9 ton thrust M88-4E although that would be stretching things a bit too far. But Snecma has already done some serious work on an uprated M88 which is termed the M88-9.

                                      First, the radar : the current RBE-2 AESA provides 10 more azimut coverage compared to the PESA version (70 vs 60) and an increased range of more than 40%
                                      In order to meet the UAE requirement, the power output will be increased from 9.6 kW to 14 kW by changing the cooling pomp. This should provide an additional 10% range bonus.

                                      UAE derivative of the M88-4E, called M88-9, will reach 9 tonnes of thrust by increasing the entering airflow from 65 kg/s to 72 kg/s as well as the compression rate from 24.5 to 27. As already said, this engine requires the air intake to be enlarged which is (was ?) a major blocking point in the negotiations with the UAE : Such a structural modification is not cheap and the costs will most probably have to be shared between the two countries.

                                          Lots of classified answers. However, the numbers you cite are from an old interview in DSI. These values aren't anymore actual as they concerned a prototype made with US modules EU made UMS modules presented better capabilities. As you say, new GAAs modules are available, easier to cool etc. I do not know for certain, but i do not think one will see RBE2AESA (apart from the prototype) before F4 standard.
