    Yahoo, thanks for that AWST article. Pretty informative from a technical point of view. Found out the significance of why the LCA’s wing root extends so far forward of the intake…

    Most of the dates mentioned in the article can pretty much be trashed but a good read nontheless.

    Regarding the South African development of avionics… During apartheid, no country was willing to touch it… except for Israel. Israel and SA had many joint ventures and quid pro quos regarding military and nuclear technology.

    One of the pics has a rendering of a Predator lining up for a cat launch. 😀

    I wonder how long of a traverse of the cat would be required to rip the dainty nose gear off the Pred? 🙂

    Finally we can bury the 1983 “start” date that’s mouthed by lazy reporters including R. Bedi.

    Project definition stage was completed late 88. So the actual development of the plane started around early 89. I am assuming it took a few months to get the tranche of money for developmental phase. Btw, that is an underestimation of the time in the Indian bereaucratic system but we’ll go with that.

    I think they are wrong 😀

    Fair enough…

    excellent, I’m glad we solved the question about the beginning date of the LCA program. That wasn’t so bad.

    So, what in your opinion is the start date? 🙂

    I will address some of the other points but this one is a ‘gimme’.

    Yet on the other hand, the IAF is an airforce where dirty fuel and FOD still seem to be regular occuring problems. It is no problem if a crewchief at the squadron accidentally drops a hammer on the wing of a metal aircraft. Were he to do that on a composite wing, you’d need to get that wing checked at depot level. I’m personally not sure if the somewhat lower weight of composites is worthy sacrificing a lot of operational simplicity for. You can’t patch up composites, you can with aluminium.

    So in your opinion, the cost/benefit of using high composite airframes doesn’t work out. But then we are seeing a trend in newer airframes, fixed wing and rotary, a distinct move towards greater composites usage.

    Either, engineers and program technical managers spanning countries are collectively wrong or you have reasses your opinion?

    Yes, they have. Spain builts the CASA transport planes and has built the CASA 101 trainer aircraft years ago. If they would have the money they could built such a fighter.

    That’s exactly the point! The countries that can build a plane from design to manufacture phase also have long pedigrees in doing the same.

    When India started the LCA project it had no design infrastructure and all of its design skills acquired from the Marut project were allowed to atrophy… Basically starting at square one.

    What country or consoritum would have wanted to let India, a country that brought nothing technically or, at that time, financially to the table and allow it to have complete technical and specification authority?

    BTW, the proper description of LCA’s wing is compound delta. Please none of this cranked delta business.

    That fact that the indistry now can built a plane for the nations airforce, is a good step, but it can be achieved by other means. Cooperation in international programms for example give you the same level of experience.
    And we do not know if the LCA is competetive on the world market without heavy help from the Indian government.

    So, you’re saying that Spain and Italy have top-to-bottom ability to design and build a Eurofighter caliber aircraft since they’ve built parts and pieces of it and test fly it?

    Notice that the much quoted 1983 “start date” is nothing more than the begining of the feasibility study. Meaning that it was only meant to gauge the level of competency, money, and ability the prospective project required. Along with how much the project would cost, etc.

    Only in 1987 did the project definition stage start, which ended in late 1988. Still hardly much work was done on the actual plane. This phase was to nail down the capabilities the IAF wanted in the aircraft.

    It can be justifiably argued that the actual funding for the development of the plane only started around 1988-89 timeframe.

    The first flight from start of development took about 13 yrs. Admitedly lengthy timeframe due to the political, technical, and managerial hurdles the project had to manuever.

    A fighter that is too complex to be used as a simple and rough little CAS fighter, too short ranged to be a striker and too limited in range and combat power to act as a fighter.

    The Gripen’s specs wrt to the bolded parts above are about the same as the LCA’s. Would you have the same misgivings about the Gripen?

    So in the end it will be a point defense fighter with limited air to ground capability.

    Did it occur to you that maybe, just maybe, it was the IAF that drew up the specs for the LCA that the Industry has been trying to meet? What? The end user drawing up the specs for equipment? What a novel idea!

    For the industry however it does mean that they went from being a pure licensce production industry to becoming a system builder, capable of designing everything from engines up to a complete airplane.

    Yet I doubt if tha was worth the money spent on the project.

    You are admitting that the project is allowing the industry to be come mature enough to be a complete system designer and builder, yet question if that was worth it? Hmm… Interesting. So, it would be more worth while in money and time to just continue to license build without acquiring any more capabilities and continue the cycle of licence building with nill inhouse design capabilities?

    By any chance, would you be an advocate of only having the US, EU, Russia, and China as the only entities having the ability design and build complete systems?

    said [Warnes] in the same issue makes a whopper of an error labelling the indian LOH program (proposed purchase from external sources) as a hi-alt vehicle only. the reality is the LOH will be used as a scout helo all over the place, the Dhruv as utility & light attack and the new Ardigen engine Dhruv as utility in the high himalayas. this is well documented yet he makes such a simple error.

    … errors like that absolutely destroy the credibility of any article, no matter if the rest makes any sense or not. Because the writer is appearantly too ill-informed or too lazy to check his facts, why should i trust the rest of the article?

    The pace of flight tests have slowed due to two reasons:
    – The main flight testing facility is experiencing monsoons
    – The PV2 is being readied in the mean time for first flight later this year

    The LCA program has four main goals:
    – To move the Indian aerospace industry forward in terms of design and manufacturing capability. This move forward is more of a skip forward which is meant to leap frog certain technologies and phases.
    – To move the avionics industry forward, again attempt at leap frogging
    – To reduce dependence on other countries for the “meat and potatoes” of the air force
    – To produce a fighter for the air force that is at least a peer in its threat environment

    When the LCA enters service, all of those goals will be met to varying degrees. Obviously, the biggest gainers would be the design and manufacturing industry while the avionics industry’s gains would be much more modest. In the process, the air force will have a fighter that is much better than the plane it will be replacing while still being relevant within its threat environment.

    Now, what part of that program doesn’t make sense?

    The problem with buying out the RN SHARs is that the IN wont be able to use their primary weapons. The avionics would need a tweak to be able to handle the IN weapons. Not necessarily a trivial undertaking with source code release and what not.

    Why you are so sure that ADS will be there in 10 years? It can be 50 years.

    Actually, it will take 57 yrs to build the ADS, by which time it will be obsolete and children of current AFM forum members will start threads like:

    ” Does the ADS program make sense?”
