Tejas is better than MiG, it's the best: Pilot

[DESERT FIGHTER]

Dumbass he means the radar nose! The composites are absorbing radar waves. That is why he wants a quartz one to utilize the full 150 KM ( Radar is hybrid of Indian MMR 120km vs 2ms and ELTA 2032).
A Mig 21 uses Gryfo radar and in newer bison ones we have ELTA 2032.

http://www.iai.co.il/sip_storage/FILES/0/38030.pdf

Clean RCS of tejas is 0.3 ms due to size and composite usage.

Dumbadd guess what... its range is 45-50 ! and indian airforce is trying to get it to 80km... lmao @ ur nonsense.

And RCS of 0.3 ..

india already has a 5th fighter the LCA .. with a smaller RCS than a F-35 ..

 

[gslv mk3]

When Pakistan announced their completion of the 50th JF-17 yesterday, I bet iaf is scared. They can do nothing but to push the incomplete tejas forward desperately to save face!

Cheap publicity manoeuvres .... anyhow, please go ahead and sell it to some corrupt African state.

In real life mig-21 can hunt Teja turkey, as many times you fly both against each other.

Like how Pakistan is trying to sell JF 17 to Zimbawe & Bangladesh??....

 

[gslv mk3]

Yet far less crashes.. India crashed over 1100 jets in the past 20 or so years a world record..


P.S : did some carpenter produce Lcas body?

Haha and he is back to entertain us....Any more earth shattering BS this time??

Like 'Shaurya pure BM with 50 km apogee' 'supersonic turbofan on Brahmos' ??

Ever heard of the term 'airframe' ?

Heck India can produce airframes for many aerospace vehicles-Ranging from Space Launchers to Re usable Launch Vehicles to Fighter jets..

Now I am waiting to see a fully ' Pakistani designed airframe' for a fully 'Pakistani developed aircraft'....

Cool...we cant do anything poor us... Now try fixing LCA with its 45km detection range n induct it by 2050...your imaginery drawing board is waiting.

 

[gslv mk3]

Cool... now try fixing LCA with its 45km detection range n induct it by 2050.

Ever heard of term 'radome' ?? New quartz radome is already on its way ( RFI & RFP was issued a few months back).Its our own radar with Israeli processor.
And this,seems to be the joke of the day

Yeah still has more Pakistani components,design that Lca,lch,Arjun combined have India. Parts.. If any..

JF 17 has more Pakistani designed components & design than LCA,LCH and arjun combined !!!

let alone one of them,may be LCA or LCH,There are more Indian components on the MKI than Pakistani components on JF 17

Indian Contribution

The Su-30MKI contains not only Russian, French, South African and Israeli Customer Furnished Equipment (CFE), but also a substantial percentage of Indian designed and manufactured avionics. They took six years to develop from start to MKI. Advanced avionics were developed by DRDO under a project code named "Vetrivale" (a Tamil name for the victorious lance carried by the youthful Lord Karthikeya or Murugan, a son of Parvati and Shiva) in close collaboration with the PSUs and the IAF. Indian avionics have been received and acknowledged enthusiastically by the Russian principals.

The following are the components developed by Indian agencies:

• Mission Computer cum Display Processor - MC-486 and DP-30MK (Defence Avionics Research Establishment - DARE)
• Radar Computer - RC1 and RC2 (DARE)
• Tarang Mk2 Radar Warning Receiver (RWR) + High Accuracy Direction Finding Module (HADF) (DARE
• IFF-1410A - Identification Friend or Foe (IFF)
• Integrated Communication suite INCOM 1210A (HAL)
• Radar Altimeter - RAM-1701 (HAL)
• Programmable Signal Processor (PSP) - (LRDE)
• Multi Function Displays (MFD) - Samtel/DARE

The 32-bit Mission Computer performs mission-oriented computations, flight management, reconfiguration-cum-redundancy management and in-flight systems self-tests. In compliance with MIL-STD-1521 and 2167A standards, Ada language has been adopted for the mission computer's software. The other DARE-developed product, the Tarang Mk2 (Tranquil) radar warning receiver, is manufactured by state-owned BEL at its Bangalore facility.

These avionics equipment have also been certified for their airworthiness in meeting the demanding standards of Russian military aviation. The cumulative value of such indigenous avionic equipment is estimated to exceed Rs. 250 lakhs per aircraft. Since the core avionics were developed by a single agency (DRDO) - they have significant commonality of hardware and software amongst them using a modular approach to design. This obviously results in major cost and time savings in development; it also benefits the user in maintenance and spares inventories.

The DRDO has gone a step further and come out with a new design of the Core Avionics Computer (CAC) which can be used with a single module adaptation across many other aircraft platforms. Thus the CAC which is derived from the computers designed for the Su-30MKI will now be the centre piece of the avionics upgrades for the MiG-27 and Jaguar aircraft as well. The CAC was demonstrated by DRDO at the Aero India exhibition at Yelahanka and attracted a good deal of international attention. Taken together with the systems already developed indigenously for the LCA (such as the Digital Flight Control Computer and HUD), clearly Indian avionics have a significant export potential in the burgeoning global market for avionics modernisation.

The navigation/weapons systems from the various countries were integrated by Ramenskoye RPKB.

HAL will supply components to Irkut for 300 Su-30s meant for export to Malaysia and Algeria apart from those meant for IAF.[7]

Now JF 17,no chinese designed avionics are added in the list

Pakistan Aeronautical Complex Kamra - Avionics Systems Co-produced Projects

Even the RWR is Chinese design,and he claims to have more indigenous components than LCA, LCH combined...!!

 

[gslv mk3]

@DESERT FIGHTER

I guess you doesn't know that tejas has very high composite content,and has much cleaner profile & smaller size than your JF 17.

How Indigenous is the LCA,lets see

Here is a brief development history of tejas

In 1983 IAF realized the need of an indigenous combat aircraft for two primary purposes. The principal and most obvious goal was the development of a replacement aircraft for India's ageing MiG-21fighters.To better accomplish these goals, the government chose to take a different management approach, and in 1984 established the Aeronautical Development Agency (ADA) to manage the LCA programme.
The IAF's Air Staff Requirement for the LCA were not finalised until October 1985.Project definition commenced in October 1987 and was completed in September 1988. Dassault Aviation of France was hired as a consultant to review the PD and provide advice based on its extensive aviation expertise. The PD phase is a critical early element in the aircraft design and development process because from this flow key elements of the detailed design, manufacturing approach, and maintenance requirements

Yes, Dassault was hired to review the Project definition,I hope you know what that is

Early proposals & wind tunnel models...

And finally...

The LCA design was finalised in 1990 as a small tail-less delta winged machine with relaxed static stability (RSS) to enhance manoeuvrability performance.

Phase 1 commenced in 1990 and HAL started work on the technology demonstrators in mid-1991; however, a financial crunch resulted in full-scale funding not being authorised until April 1993, with significant work on FSED Phase 1 commencing in June. The first technology demonstrator, TD-1, was rolled out on 17 November 1995 and was followed by TD-2 in 1998, but they were kept grounded for several years due to structural concerns and trouble with the development of the flight control system

The Flight control system

In 1992 the LCA National Control Law (CLAW) team was set up by the National Aeronautics Laboratory to develop India's own version.The CLAW team's scientists and mathematicians were successful in developing their control laws, but could not test them since India did not possess advanced real-time ground simulators at that time.

Accordingly, British Aerospace (BAe) and Lockheed Martin were brought in to help in 1993, but the effort required for the Aeronautical Development Establishment to code the control laws into the FCS software proved a much larger job than originally anticipated.



Specific control law problems were tested on BAE's simulators (and on HAL's, once theirs became available).

As it was being developed, progressive elements of the coding were checked out on the "Minibird" and "Ironbird" test rigs at the ADE and HAL, respectively. A second series of inflight simulation tests of the integrated flight control software were conducted on the F-16 VISTA(Variable In-flight Stability Test Aircraft) simulator in the U.S. in July 1996, with 33 test flights being carried out. However, Lockheed Martin's involvement was terminated in 1998 as part of an embargo enacted by the U.S. in response to India's second nuclear tests in May of that year.

The NAL's CLAW team eventually managed to successfully complete integration of the flight control laws indigenously, with the FCS software performing flawlessly for over 50 hours of pilot testing on TD-1, resulting in the aircraft being cleared for flight in early 2001. The LCA's maiden flight was made by TD-1 from National Flight Test Centre (NFTC), near Bangalore, on 4 January 2001, and its first successful supersonic flight followed on 1 August 2003. TD-2 made its first flight on 6 June 2002. The automatic flight control system (AFCS) of the Tejas has been highly praised by all of its test pilots, one of whom said that he found it easier to take off with the LCA than in a Mirage 2000

Tarmak007 -- A bold blog on Indian defence: The Iron Bird Team: A Tejas story never told before!

Now the Multi Mode Radar

HAL's Hyderabad division and the LRDE were selected to jointly lead the MMR program and the radar development effort began in 1997.

The DRDO's Centre for Airborne System (CABS) is responsible for running the test programme for the MMR. Between 1996 and 1997, CABS converted the surviving HAL/HS-748M Airborne Surveillance Post (ASP) testbed into a testbed for the avionics and radar of the LCA.

The coherent pulse-Doppler Multi Mode Radar is designed to operate equally effectively in the Air to Air and Air to Surface domains. Jointly developed as an Indian – Israeli venture, it features multi-target Air to Air Track, Hi Resolution Synthetic Aperture Mapping and specialized Air to Sea modes. The radar facilitates all weather employment of a variety of Air to Air and Air to Surface Weaponry, and is the primary targeting sensor on the Tejas.

EW Suite

The electronic warfare suite is designed to enhance the survivability during deep penetration and combat. The LCA's EW suite is developed by the Defence Avionics Research Establishment(DARE) with support from the Defence Electronics Research Laboratory (DLRL). This EW suite, known as Mayavi, includes a radar warning receiver (RWR), Missile Approach Warning (MAW) and a Laser warning receiver (LWR) system, self-protection jammer, laser warning system, and chaff/flare dispenser

Avionics

Open Architecture Computer (OAC) designed and developed by ADA, combines the functions of earlier mission computer, display processor, video switching unit and mission preparation and retrieval unit. It is designed based on open system interfaces standards, which provides interoperability, scalability, and portability. OAC drives three multi-function displays, HUD and the helmet-mounted display. This open architecture design will allow the designers to continuously adapt and upgrade Tejas to meet the challenges of modern warfare.

Cockpit

The cockpit has two 76mm×76mm colour liquid crystal multifunction displays developed by Bharat Electronics, a head up display developed by the government-owned Central Scientific Instruments Organisation (CSIO) in Chandigarh, a liquid crystal return-to-home-base panel and keyboard. The pilot also has a helmet-mounted display and sight (HMDS). The hands on throttle and stick control system minimizes pilot workload and maximizes situational awareness.

The Airframe-Composites

The Tejas employs CFC materials for up to 45% of its airframe, including in the fuselage (doors and skins), wings (skin, spars and ribs), elevons, tailfin, rudder, air brakes and landing gear doors. Composites are used to make an aircraft both lighter and stronger at the same time compared to an all-metal design, and the LCA's percentage employment of CFCs is one of the highest among contemporary aircraft of its class. Apart from making the plane much lighter, there are also fewer joints or rivets, which increases the aircraft's reliability and lowers its susceptibility to structural fatigue cracks.



The tailfin for the LCA is a monolithic honeycomb piece, an approach which reduced its manufacturing cost by 80% compared to the customary "subtractive" or "deductive" method, whereby the shaft is carved out of a block of titanium alloy by a computerised numerically controlled machine. No other manufacturer is known to have made fins out of a single piece.

The use of composites in the LCA resulted in a 40% reduction in the total number of parts compared to using a metallic frame. Furthermore, the number of fasteners has been reduced by half in the composite structure from the 10,000 that would have been required in a metallic frame design. The composite design also helped to avoid about 2,000 holes being drilled into the airframe. Overall, the aircraft's weight is lowered by 21%.

There are also Mechanical Systems developed indigenously

GTSU 110

A Jet Fuel Starter has been designed and developed by Engine Division of HAL, Bangalore, especially to start the engine of Tejas on ground and in the air. Design optimisation of rotating elements and shaft has been achieved by use of 3-D modelling, dynamic and stress analysis software to reduce weight of the JFS with the safe margin for shaft critical speed and element's resonance frequency as well as to reduce vibration and noise levels.

Salient Features

Aircraft-Mounted Accessories Gearbox

An Aircraft-Mounted Accessories Gearbox (AMAGB) has been designed and developed for Tejas. It is a lightweight, single-input, multi-output gearbox, which takes its input drive from engine through a power take off shaft at a rated speed of 16810 rpm. AMAGB has a high power-to-weight ratio and a self-contained lubrication system. It carries four aircraft accessories on its output pads, viz., two hydraulic pumps (60 kW @ 6000 rpm each), one generator (40 kW @ 7950 rpm), and one starter unit. Together, these cater to a major part of hydraulic and electrical power requirements of the Tejas and hence forms a crucial part of its secondary power system.

Carbon-Carbon Brake Discs

Carbon-Carbon Brake Discs have been designed and developed by DRDO especially for Tejas. These discs provide drag, absorb kinetic energy of the aircraft by converting it into heat and hold the aircraft stationary against engine thrust.

Not to mention,the Landing gear developed for both Airforce & Navy Versions

Developing a landing gear for a carrier-based fighter is no easy feat,I guess you know.

If you think JF 17 have more indigenous content than this,prove it then !!!

 

[gslv mk3]

Again, diverting when you have no response left.. ... talk to me when you have anything locally designed in Pakistan except a twin propeller plan like Musha (or whatever its name is)...Getting mahines designed by China and then locally producing the low end components of that within Pakistan is hardly worthy of anyone's jealousy

Locally designed?WTF are you talking about?

Super Mushak is a SAAB Supporter with a new engine ( imported Lycoming ) and a new fuel injection system (imported,again).Hardly Pakistani.

Thats an easy question. By having very badly trained pilots flying planes. And we know the quality of Indian pilots during the wars we have fought with you all.

Maybe thats why you lost half your territory in 71?And what did your airforce do when Mirages were pounding Pakistani positions at Kargil??

@gslv mk3

If they were even 50% as transparent as India is, they'll truly know how pathetic their defense industry really is.

There's nothing to prove.

They're budget is 6 billion dollars. To upkeep and obtain new systems for their 3 main branches. How much of that shitty budget is used on R&D to produced everything, "indigenous", like some of them think in their heads? That little amount is going straight to missile tech. if anything.

Well we got sources that tell significant foreign help for assembling nuke plants ( reactor vessels,pumps are from China) & space program ( Paksat 1R fully made by China) So it is safe to assume how much 'indigenous component' they have in defense projects.

A few days back,a Pakistani member was claiming that they developed turbofan for Babur indigenously.

We could develop the miniature turbofan ' Laghu Shakti ' only with decades of experience in developing turbojets,turbofans & Jet fuel starters ( GTX 37,HJE 2500,Kabini,Kaveri,PTAE7,GTSU 110)

And they claim that they developed a miniature turbofan without any experiences in designing a gas turbine !!

I dont know,this article is from October 22, 2013

This suite, however, remains unproven, although it has been flight-tested on an HS-748 Avro flying testbed by the DRDO’s Centre for Airborne Systems (CABS) since 2007. To certify this EW suite on the Tejas Mk1 MRCA, at least 40 additional test-flights on a PV-1 flying testbed will be required, which in turn will further delay the Tejas Mk1’s operational flight certification by at least 18 months.
