    LCA TEJAS MK1 & MK1A: News and Discussion

    I don't know who is feeding you wrong information about con-trail !! Contrail is not associated with supersonic flight alone & the use of after burner in particular. You may see it even for M==0.85-0.9 at cruising altitude for civilian aircraft; Check this picture; Airbus 340 at cruising...

    Have you done the math for quoting"100 kms" figure? Assuming the plane got supersonic just vertical over the goatfcker... Speed of sound (in air at standard conditions): 1235 km/hr Observer distance: 10 kms (>30000 ft) Time taken by sonic boom to reach the ground observer: 0.5 minutes (30...

    IMO, this is not deemed as advantage of Supercruise w.r.t response at ground level.; 1. Considering ground troops equipped with MANPADs, aircraft cruising at 30K is out of range for any contemporary MANPADs (For e.g. Stinger up to 20k feet). 2. Considering sunny & clear sky, as the height...

    I would call a scam if GOI doesn't order another tranche of 36 Rafale OTS. It would be criminal mixure of short-sightedness and wishful thinking. Moreover, over $1.5 billion would go down the drain for acquiring ISE for just 2 squadrons worth of aircraft. In a way, you are funding Dassault for...

    12 Kits of More MKIs are going to be ordered. So, Nashik line will be occupied for a couple of years or more. If Govt. is serious about AMCA, it should collaborate with Pvt Sector like Dassault to modernize it to western standards and enhance level of automation. Dassault's expertise in PD-PLM...

    This story is first broken by Anatha Krishnan on Tarmak007 If I heard & interpreted it correctly; 1. First Flight of Tejas Mk1A LSP: Last Quarter of 2022-23 i.e. In the Year 2023 (Jan-Feb-March are the last months of fiscal followed in India). 2. Two LSPs will be build for testing and...

    It's all about Money. At the end of fiscal year, particularly when financial conditions are contained, Govt. tend to roll over expenditures in next fin year to keep its book good enough on Fiscal Deficit point of view. Quite a standard practice in almost all the govt departments. I am sure the...

    Strange to see that first flight of Mk1A will take place in 2023 despite the fact this version is having similar air frame as Tejas Mk1 FOC. Assuming its first roll out in early 2024; the order will be completed in 6 years time frame i.e. in 2030 (@ 14 aircraft per year). And we are expecting...

    Cool !! In the meantime, SAAB engineers has already stopped doing anything meaningful till MWF gets far ahead. Wishful thinking at best. May be we need to hold our horses till the roll-out of MWF; Because, God forbid, if didn't work as per the expectation or gets delayed, the egg will be all...

    You are completely wrong on composite part ! Composites are not solely used for RCS reduction. Composites are used in aircraft primarily due to better strength as compared to conventional structural material like Aluminum alloys & Steel (Tensile strength: 1000 MPa & above for typical...

    For that you need to tag, @livefist & @shivaroor. Things will go auto-pilot then. :rofl: Other reason is that, the spat involved low key people or "Anons" unlike in previous case where HAL itself did Op "Swift Retort" on formal Admiral for his adverse comments on Naval Dhruv. :cool3:

    Order book numbers & its correlation with production rate is a strange logic ! May be it's true from economy of scale perspective but when you sign a contract with the vendor, the period of delivery is explicitly mentioned along with penal clauses in case there is a delay (The dreaded LD clause...

    Yeah, that's why I was wondering what these people are up to ? I am sure none had flown even a Cessna in their life yet they are preaching/insulting the retired air marshal for his ignorance about Tejas or greed for kickbacks while ignoring his role in Tejas development. As a chief of IAF...

    Much of his complain is against HAL not Tejas. HAL played its hand too far by attacking armed forces for their interest in imported aircraft (NUH fiasco). Now it's been returned in kind by the top veterans by highlighting delays on their part. Unfair to attack AVM Nambiar who has contributed...

    May be off-topic a bit, but you know what, those theories of threat from Mig 15 during Korean wars (the dreaded "Mig Alley") and NAM Mig-21s giving tough time to USAF/USN during Vietnam war were most of the time exaggerations of US's own arms lobby which wanted continuous funding for their up...

    Quite possible; in fact the demonstration that I referred was happened in 2009-2010. In a decade, they must have done "something" which lead to this improvement. It's an achievement for Gripen E to reach sustained supercruise without making any conspicuous changes in air intakes and air frame...

    It can happen if they also improve the intake design apart from reducing drag of the aero-structure. The ADA must incorporate supercruise feature to make the design relevant for at least 2 decades w.r.t its peers like Gripen. They have demonstrated supercruise with some A2A missiles but no...

    Could you explain how does the Gripen capability of Mach 1.1+ without using after burner is a joke? Gripen E/F "Power Plant The engine, a General Electric F414G turbofan, is a modular, fuel-efficient low-bypass ratio, afterburning turbofan with the latest technology. With a thrust rating of...
