I think Harry has the real story on diffs between the vanilla LCA and the naval model. But he’s keeping a low profile since the admin thing ..probably waiting for the coronation ceremony before risking a brawl 🙂
its too costly for everyone to be hand-rolling their own supporting sw and
development toolchain anymore. I heard some dark rumours of even linux
being used in defence sector – EETimes had a piece on it.

I think the LCA has only two wet hardpoints – the innermost on the wings.
many cos tend to use C++ as a better-C, utilizing a subset of its features
to better modularize the codebase and make it somewhat safer. but its
possible to create bad sw in any language given sufficient efforts 🙂
I wonder what operating system (if any) run on missiles and onboard mission computers ? some of the OS vendors sell ARINC compliant kernels to develop aerospace applications on…
http://www.windriver.com/products/platforms/safety_critical_arinc_653/
I figure in many applications, the developers themselves write a minimal
kernel and depend on a collection of interrupt handlers and timer routines to serve as the “application”.
Hyperwarp, yes. aircraft and satellites need far better sw than network gear though. the timelines and development process reflect that. in the network world, there is usually a release every quarter and lots of corners are cut. I can only imagine after seeing the chaos and sloppy practices what it could be in a “general” non-embedded environment 🙂
is the SD-10 still using the R77s AGAT seeker ? if so, the differences with R77 will be due to airframe and motor power, not in seeker performance.
most of the compute intensive work is done by dedicated ASICs, fpgas and
DSPs. it doesnt matter how powerful the general purpose CPUs are. cisco
uses 300-600mhz range Mips, motorola cpus as control processors yet
their boxes process and forward a lot of pkts / sec…far beyond the ability of say a 3 Ghz intel and a software operating system.
dont kid yourself , stuff like a distributed system for aircraft, routers these are 10000 times more complicated and expensive to create than a desktop PC or a playstation.
and I do it for a living – before anyone jumps on me.
PLA has no respect for democracy or free elections – that
much is clear from his writings. Its incongruous for him to
argue about how to do it better.
> Harry has many votes and I am personal not happy
> with that
accept the choices people make, this isnt some authoritarian regime here.
X-posted from BR. the AL55 is based on AL31F. no afterburner
and much reduced size & thrust ofcourse.

HEADLINE: 7.1. RUSSIA TO SUPPLY AIRCRAFT ENGINES TO INDIA [$]

India will equip its training planes with Russian-made AL-55 engines, which are not yet in regular production. This deal could bring in over $200 million for the Russian aviation industry. According to analysts, winning this tender proves that Russia is still able to offer promising systems to the fastidious Indian arms market.
In early April India announced a tender to purchase engines for its HJT-36 training aircraft. The Ufa Engine-Building Association (UMPO) has won the tender. A source close to the Federal Military Technology Cooperation Service (MTCS) told us that the AL-55 engine – designed by NPO Saturn, and to be produced at UMPO – won the tender, defeating the Larzac engine produced by Snecma.
A source at the MTCS said that Rosoboronexport (Russian Arms Exports) will sign the contract for supplying AL-55 engines by the end of May, and implementation will start next year.
India faces an urgent need for a “flying desk,” says military historian Mikhail Barabanov. Due to weak pilot skills, in the 1990s the Indian Air Force lost over 100 fighters in crashes – more than in the wars with Pakistan. The Indian aviation industry is not able to produce its own up-to-date engine.
The AL-55 engine is not yet in production, and launching regular production will require large-scale research and development efforts, says Konstantin Makiyenko, an analyst with the Strategy and Technology Analysis Center. Thanks to the Indian contract, Russia will be able to launch production of the engine with thrust power of 2.5-3 tons, which is not available at the moment.
Konstantin Makiyenko: “This win is significant because we are still able to sell unfinished systems to the demanding Indian military, despite keen competition from Western producers. What’s more annoying is that due to the absurd rivalry between MiG-AT and Yak-130 planes, last year Russia lost a $1.6 billion contract to the BAE Systems obsolete Hawk training jet for intensive pilot training.”
According to a source close to the MTCS, Russia will now have to be content with supplying spare parts for the Indian training plane – in addition to engines, the supplies may include ejector seats and armaments.
The deal on the AL-55 engines may entail other large contracts for supplying engines to India. Yuri Yeliseyev, general director of the Salyut plant in Moscow, says Salyut has been working with RSK MiG on testing the AL-31 engine, which can be installed in the MiG-27 fighter-bomber, produced in India from the mid-1990s. Overall, 165 MiG-27 planes were constructed in India.
If the Indian military accepts the offer from RSK MiG, the value of the deal could exceed $250 million, says Makiyenko.

MOSCOW AUG. 22. Hindustan Aeronautics Limited and other Indian companies will be involved in Russia’s deal to supply Sukhoi multirole jet fighters for Malaysia.
The IRKUT aircraft corporation plans to extend its production-sharing arrangement with HAL in the construction of the Su-30MKI planes to IRKUT’s newly-signed contract to build Su-30MKM fighters for Malaysia, the company’s head said here.
The president of IRKUT, Alexei Fyodorov, told The Hindu that HAL’s share in the company’s $900-million deal to build 18 Su-30MKM planes for Malaysia will be about 10 per cent of the cost of the airframes.
Indian companies, involved in the supply of electronic and radio devices for the Su-30MKI project, will also be invited to join in, Mr. Fyodorov said, as all the components sourced from India for the Su-30MKI will be present in the Malaysian version of the plane.
google, its a secretive org mentioned in a robert ludlum novel.
an org so powerful as to hack into NSA computers at will…and have visibility into the US command chain.

HAL bags USD 30 mn Russian order for Sukhoi-30’s to Malaysia
Bangalore: Hindustan Aeronautics Ltd has bagged a USD 30 million order to supply components to Russia, to be used in the 18 Sukhoi30-MKM fighters, which Moscow will deliver to Malaysia.
The Bangalore-based public sector defence undertaking will supply major sub-assemblies including Canard, stabilisers and fins to IRKUT Aircraft Corporation, the manufacturers of the Sukhoi aircraft.
‘We are supplying major sub-assemblies for the project. In value terms, it is over USD 30 million (Rs 150 crore),’ HAL Chairman N R Mohanty told reporters here today. Malaysia early this month signed a deal with Russia for 18 Sukhoi fighters based on MKI version jointly developed by Delhi and Moscow for specific requirements of the Indian Air Force.
‘The sub-assemblies would be manufactured at our Nasik plant and later assembled in the fighters at Russia,’ he said. HAL, which extensively uses advance composites in its aircraft upgradation, indigenous LCA and IJT programme, will also supply composites to IRKUT, to be used in the multi-role fighter for Malaysia.
India already has an arrangement with Malaysia to supply components and assemblies for Chetak and Cheetah helicopters, used by the Malaysian defence forces. ‘We are in discussions with the Russians to use more Indian components in their aircraft programmes,’ Mohanty said.
russia is willing to provide more technology subsystems to
india. french price will be high(er) and they’d like to sell more complete systems without revealing the design secrets.
in that case I doubt india will get involved in the pak-fa
project. HAL has been working on finalizing the design of
the MCA. Russia could be engaged on certain aspects like
exotic materials, engine tech, TVC (a must if it has no vertical tails), RCS reduction tools and AESA radar though.
