Why wasn't the landing gear retracted? it was out all throughout the flight, any particular reasons for doing so...
Standard practice for many aviation firms. Retracting isn't the stuff they are not sure about, its getting the damn landing gear out which gives them jitters. Drag isn't the concern on the first flight, they use the data gathered from the first few flights to fine tune the controls so that the difference in actual and simulated performance can be reduced and the system calibrated accordingly. There are multitude of things that can go wrong on the first flight, like frosting on the movable parts which might restrict their movements, the slipstream might knock the gear back into the bay. So its better to not actuate the non critical systems to minimize risk.

40 tejas a year... dream come true. the economies of scale will bring down the cost significantly
Six Tejas Squadrons By 2022.

Tuesday, May 22, 2012
By : Defence News Admin

The Ministry of Defence informed Parliament today that six squadrons of the LCA would be inducted by 2022 -- the end of the 13th plan period. Full text of what was said:

"There has been delay in the manufacturing of indigenous Light Combat Aircraft (LCA) Tejas. This is a design and development project and the Aeronautical Development Agency (ADA) is the nodal organization for the development of Light Combat Aircraft, Tejas. The Initial Operational Clearance-1 (IOC-1) for the Tejas has been achieved on the 10th January, 2011. Presently, LCA development activities leading to final operational clearance are in progress. The deliveries of aircraft are scheduled in the 12th plan period. It is planned to induct six LCA squadrons by the end of 13th Plan."

The Indo-Russian multirole transport aircraft (MTA) also came up in Parliament today. The Defence Minister said, "The review of the Multi-role Transport Aircraft (MTA) programme by the Government is an ongoing process. After signing of the Inter-Governmental Agreement in November, 2007 for Design, Development and Production of MTA, Government's approval was conveyed for signing the Share Holders Agreement between HAL and Russian partners on 30th August, 2010. The same was signed on 9th September, 2010. The Memorandum of Association and Articles of Association was signed on 25th November, 2010. For implementing the "" 'programme a Joint Venture company has been incorporated between Indian and Russian partners on 50:50 funding basis in December, 2010. The investment for the programme has been worked out to be $771-million at 2012 Price Level. The CEO of the joint venture has also since been appointed for implementation of the programme."

I think its a great thing that our HAL is growing so much fast and developing such a huge and massive planes with the help of other nations.It is surely making our position very strong in context of air forces of different nations.

re: Stealthy LCA Mk3, AMCA on the cards

Excellent.

Three important things here that immediately come to mind & I base this in part on all the other data that has come out over the years.

This is an excellent view of how DRDO has moved up the ladder & is looking towards the cutting edge, as versus just waiting for service requirements and then responding. That means that technology development has to happen in a vacuum, waiting for the right program - and if that program is not launched, it is wasted. To get out of this, the DRDO with close cooperation of visionary leaders like Sundarji of the Army, and several others, launched programs like the IGMDP etc. The challenge with all of these programs has been that they started from scratch & hence timelines suffered and the organization suffered vitriolic attacks for the delays, with no attempts made to look at the infrastructure related aspect of the equation at all.

Now, the first: AWACS. India started off small in radars and has rapidly moved up to the point that its current in development systems are all AESAs, bar a few for Naval and UAV purposes which require light weight and low power- which mean MSAs. Thanks to multiple programs underway, India has achieved a fair degree of competence at LRDE and BEL, with hardware and software capabilities both established. Keeping in mind the future scenario with low viz platforms available to both near term challengers like the J-20, it makes perfect sense to invest in developing a long range airborne radar system with bistatic capabilities.
This is the perfect solution for both aircraft and cruise missiles, plus UAVs, and will round off Indian independence in this crucial arena. It will also be substantially more capable than the Phalcon and explains why the IAF has so far asked for only 5 of the type and 3-8 of the smaller EMB-145 version developed by DRDO.

Next: The LCA MK3 is brilliant news. Several years back, this same topic came up for discussion and the perception clearly was that the IAF was waiting for the LCA to mature further before asking ADA to look at further development. Clearly, that benchmark has been crossed. With MK2 completed around 2016-18, we can look at adding more strength to the IAF with an inexpensive single seat platform that can give the IAF additional numbers (to reach its ideal 45 sq force).

The work done on RCS reduction now is also heartening. What this means is that unlike as in the LCA where the technology had to be developed along with the program, and any delays in the former meant delays in the latter, in this case, many of the core technologies will be available by the time the AMCA is launched formally.

The reference to the Kaveri means that efforts are underway to ensure the program - with Safrans help - continues. Basically two designs - one with the M88 tech for fighters, but uprated to 90 Kn level. And the second, a derivative of the already developed Kaveri for lighter platforms including UAVs and UCAVs.

The UAV references are also very interesting. The key thing is to have the right technology. Take datalinks for instance. With a start made from the Nishant program, now DEAL has much higher grade C Band datalinks that can transmit many MBPS of data from high data generating payloads like SAR etc.

Third - the open reference to cooperation also means that while India will have the baseline technology, its open to cooperating with selected nations for last mile connectivity. Dealing with these problems upfront both means better project management experience (having learnt from problems with programs such as the Arjun, where local industry could not develop an engine and we looked outside once the Army upgraded its GSQR) and also funding is earmarked upfront, leading to better cost and time estimations.
For programs such as UAVs - a critical thing is the right kind of payload. India is working on its own SAR packages (it already has ELINT) but cooperating with others for lightweight high performance payloads, codeveloping advanced mission planning & flight control software or just using experienced partners (such as IAI) for auditing, while building on the experiences of our own Nishant, Rustom etc programs means that programs can be managed more effectively.

Its also interesting to see the mention of space programs. These are vital because as the sensor grid expands, it will move into space. Right now the armed forces are firmly terrestrial with limited space assets, but over the coming decades, once they become familiar with network centricity, their requirements for more bandwidth (to communicate) and greater visibility (for optimal decision making) will continue to increase. These mean more satellites and launch on requirement. That means cost effective access to space is a priority, and that they are already working on this today, is a positive.

In all, very encouraging news - because all these activities will feed into multiple programs across the board.

I think the JV will be signed in two or three months.

re: Stealthy LCA Mk3, AMCA on the cards

first induct the tejas mk1. though drdo develops satisfactory level and quality of weapons but the companies given charge to manufacture them are no better than dead factories- latest example is of akash sam. good performance in testing but bad in post production testing. what does this indicates? that bdl and bel produces low quality products even though huge amount of money, manpower and other resources were poured to develop it for decades. this is just like getting best quality recipe, flour and kitchen but worst of possible chef to cook the food.

BEL is good. They have JVs with foreign companies for some of their stuff.

re: Stealthy LCA Mk3, AMCA on the cards

Instead of awarding the MMRCA contract to HAL, MoD could have floated a tender to private players like Mahindra, TATA etc and then given the contract to them. So whoever got the MMRCA contract may design a stealth fighter AMCA or whatever.

and those companies very frequently backtrack from JVs because of bad management and technical level of BEL.

re: Stealthy LCA Mk3, AMCA on the cards

does anyone has got an accurate knowledge about the current rcs of LCA?i read it somewhere that the clean rcs of tejas mk-1 is around 0.6 without the weapons package.is it true or another speculation coz 0.6 is a very small rcs in itself(smaller than the medium class fighters like Eurofighter Thypoon and Rafale)!

Yes it is because it has Y ducts where the compressor blades are hidden. Also the aircraft is very small compared to even the Gripen which was a deliberate choice. The Compound delta wing may also help because it is only one airfoil and has minimum moving parts, compared to an aircraft with canards and elevators.

so to become a real stealthy combat ac the rcs needs to be around 0.001 but that will mean that the entire body of tejas would have to be made of composite or an extensive(almost total) structural change to the entire fuselage part.do you think its possible in any way given that the current surface composite coverage of tejas is around 90% and the total composite usage is around 45% of the total weight of the ac!:shocked:
