I hope they dont pull the plug on Aero India 2013, I have been waiting to see the LCA in action for a long time. I hope this time around the LCA pushes the AoA envelope to the maximum it has been tested to provide the "oomph" factor.

a.peter, not sure about that article, but I think Mk.3 is far fetched now.. of course there is nothing wrong in planning, but it must be more pragmatic given staged capabilities and expertise. It would be ideal to focus on Mk2 now rather Mk3 and AMCA, which is a natural progression.

We have got long way to go in terms of the critical precision engineering sub systems like the core engine Kaveri. Which is a mandatory requirement for any jingo lungi dance from the current shivering dhotis status.
The key progress should be seen from this core engine section, when done, will put India a little ahead than china in this area of expertise. Only USA+UK chela, France, Russia are the established leaders here. If India gets ahead than Chinas ws10, then we could walk with brighter face.. where our dhoti-shiver++ just happened after china's manned space flight. So, the point is Kaveri++ is fundamental need for giving any color to lungi.

Stealth is not a precision-critical problem (in the sense - safety critical as would be the engine class).. but more of RCS. Composites themselves disperse mw radiations is the report. not sure which direction and how. need you to research and post. these information will not be available freely.

of course, you could go about from first principles, and ask questions to our radar gurus in the radar thread. our own LCA MMR is the second in the priority of things that needs to be done..

so, stealth is out of requirement right now for FoC LCA.

I came across this article which throws some light on a future LCA MKIII.. But I am not very sure about the stealthiness of the LCA(picture inset) in the article..
If fellow BRFites have some more info on this, please share.

Thanks

That fellow youtube Terence Fornoff mentioned that the Mig 21 had some sort of Israeli jammer.

I wonder whats the jammer/EW (Tarang? Mayavi?) in the LCA?

What hardware component propagates those jamming waves...the radar itself?

EL/L-8251 could make it to SEAD, not?

If one reads carefully the above article then we have reference to LCA Mark-3 but also AMCA is referred as 25 tons, rather than normal 20 tons category

The Hell Is This Aircraft At HAL's Defexpo Pavilion?-Livefist

@rajanb

Having worked at HAL, Bangalore for a considerable amount of time in the early 2000's, i would choose ineptitude as the reason.

I do not know if things have changed, but just to quote a couple of instances, a Rs 8 lakh imported autoclave (an instrument that was invented to sterilize/heat up things to a very precise temperature) was routinely used to heat up employees lunches in steel boxes. And yes, this type of abuse of expensive equipment was the standard, not the anomaly. Employees put their feet up the tables and take a siesta after lunch, keeping the phone off the hook-lest it disturb their sleep. But if this is the organization which has been entrusted to produce the LCA, good luck with it.

If ever a real life documentary was made for life @HAL, well, i would love to see the public reaction.

Many will retort that HAL might have changed in the last decade, indeed, if that has happened, i sincerely wish HAL all the best.

Note, I do not have first hand experience of the other entities associated with LCA-DRDO, GTRE, et al and I would really want the LCA to succeed.

What were you doing there? Who did you work with? And please don't tell me that you were a young intern, only there for a few months, so much so that no one would remember you.

Very interesting.

I started my career as a IBM HW engineer (late 60s) and I used to repair punch card machines. There was a particular machine to the back of a huge bank of machines. Quite often it was reported as not working! And mostly after lunch. All I had to do was change the fuse. One day I had to do preventive maintenance on that machine and to the rather lovely, flirtatious operator's surprise, I opened the cover and found a metal lunch box inside. I had a eureka moment. She used to place the lunch box inside first thing in the morning when her colleagues were trooping in. But she used to remove the metal box while it was still on! At times it brushed an exposed low DC voltage point and the fuse used to blow!. The company was a Fortune100 MNC company in those days! She was suitably warned. There was no union to back her up.

The point is, that it depends on the individual.

So when the LCA is found to have something tweaked, it needs to go back to the drawing board. i.e the people who have designed the assemblies. My hope, (Maybe a long shot) comes from my visit to ADA and I was impressed by the dedication, the fire, the patriotism in the group that I met. The group who uses the most esoteric desktops, connected to a mainframe where they churn out designs and changes.

Only after that does it goes to HAL from the various design input agencies, some within HAL.

The LCA (Light Combat Aircraft) IOC certification was done in Jan 2011.There are delays. Induction is expected in this year, by which time all teething issues should hopefully be sorted out.

My boss does the same...my company us doomed too ??

The concept of a midday nap is also prominent in other tropical or subtropical countries, where the afternoon heat dramatically reduces work productivity. The Washington Post of February 13, 2007 reports at length on studies in Greece that indicate that those who nap have less risk of heart attack.[4]

An example of a siesta-like habit can be found in Serbia and Slovenia. Especially among older citizens, it is common to observe the so-called "house rule", requiring people to refrain from telephoning or visiting each other between 2 p.m. and 5 p.m., as people are supposed to be resting; especially since lunch in Serbia and Slovenia, eaten usually between 1 p.m. and 2 p.m., is the main dish of the day. In some southern German-speaking regions, the Mittagspause (de:Mittagspause) or Mittagsruhe (de:Mittagsruhe) is still customary; shops close, and children are expected to play quietly indoors. Siesta is quite common in Italy too, especially in summer.

In South Asia, the idea of a post-lunch nap is common, and the idea of going to sleep after a light massage with mustard oil to induce drowsiness was very popular before industrialization. It was also very popular to consume a light snack during this ritual; it was thought that this practice would make one a better person.[citation needed] In Bengal, the word which describes the concept is bhat-ghum, literally meaning "rice-sleep", a nap after lunch. In north India a colloquial term sustānā (सुस्ताना), which literally means "taking small nap" (possibly of Persian origin), is used, although it does not necessarily mean siesta but it is used in same way. According ayurveda vamkukshi/wamkukshi (nap in the afternoon)वामकुक्षी for 15-30 minutes after lunch is good for your health, it does not mean deep sleep but just lying down.

Afternoon sleep is also a common habit in China and Taiwan after the midday meal. This is called wujiao (午覺) in Mainland China Chinese or wuxiu (午休）in Taiwan Mandarin. Almost all schools in Mainland China and Taiwan have a half-hour nap period right after lunch. This is a time when all lights are out and one is not allowed to do anything other than rest or sleep.

Some Japanese offices have special rooms known as napping rooms for their workers to take a nap during lunch break or after overtime work.

In Islam, it is encouraged to take a nap before Dhuhr (midday), for those doing tahajjud later in the night.[original research?]

In the United States, the United Kingdom, and a growing number of other countries, a short sleep has been referred to as a "power nap", a term coined by Cornell University social psychologist James Maas[5] and recognized by other research scientists such as Sara Mednick[6] as well as in the popular press.[7]
