Poor grammar, spelling etc.

Is this meant to be a news report or a blog of some sort?

Mate... in the other thread "J-10 vs F-22" the PDF link u page has tons of grammatical and spelling mistake .... so the same applies to that as well ???
just curious

SORRY GUYS, THIS IS NOT,WHAT I HAD IN MIND CREATING THREAD.

Initially Russian BVR will be used in the aircraft , while Russian have not provided Source code for their BVR missiles to work smoothly with new radar and the aircraft but Indian air force which has years of experience on this missiles seems to have been successful in integrating them with MMR radar , while Israeli missiles will not be having such problems since MMR HYBRID is partially based on Israeli Elta 2032 radar and will have source code of Israeli bvr missiles , MMR Hybrid’s major chuck of testing was done on board Israeli modified Boeing aircraft in Israel.

That raises the important question , how many delays as a result of trying to integrate foreign systems ?

once first phase is completed IOC will be granted to the aircraft ,and second phase of weapon testing will start which will involve firing of Air to surface missiles on ground target still and moving , Rocket pods , dropping of GPS guided/laser guided /cluster bombs on land targets , and also of free falling bombs , after which aircraft will be given FOC , which is expected by 2011-12.

They don't know what they are talking about.

After all testing is completed the Aircraft is given IOC , before December this year.

Construction of The first Tejas squadron has already begun and will be delivered sometime during the first 6 months next year. They will be stationed in Rajastan and put through their paces, While work on the second squadron begins.

After a year of actual operations in the field, as a fully fledged squadron of the IAF . 2nd squadron is inducted , Stationed? . And FOC is granted.

IAF may order more Tejas Mk-I , depending on how they operated during the last year , their need for more aircraft , and how free the production line is.

It is very likely a third squadron may be ordered and older soviet jets retired.

Nice artical about lca read from 34-43 pages

love to share this detail from this pdf

Despite delayed works, the Indian Air Force
seemed to be optimistic about the perspectives of
the “national” engine in the first half of the current
decade. According to announcements made by
Indian government in 2005, the LCA series aircraft
were to start receiving Kavery engines in 2009. In
early 2005, an engine of the type developed 96%
of the maximum design thrust during tests.
Flight tests of the bypass turbofan engine with
afterburner installed at an LCA were planned to
begin in December 2006 and January 2007. The
problems to occur during the final engine adjustments
seem to have not been solved. As a result,
in February 2006 ADA concluded an agreement
with the French firm Snecma for support with
works on the engine so as to make it flight-capable
in 2009-2010. The goal was not achieved either
and despite the official continuation of the Kavery
program, the idea of installing the engine at Tejas
aircraft, at least in the mid-term planning, seems
to have been finally refused.
In the 1990s, the Indian Air Force were going
to buy at least 200 LCA fighters and 20 two-seat
combat trainers (while optimist would announce
300 or 500 jets) with the initial combat readiness to
be reached in 2003 with the full combat readiness
to follow in 2005. One LCA of the 220 item series
was expected to cost the humble $21 million. The
sum later escalated to $22.6 million, which is also
very little compared to other 4+ generation aircraft.
According to unofficial data, though, an aircraft of
the 220 item series would cost $35 million, which
seem much more true to life.
The Tejas planes were planned to start entering
the Indian Air Force inventory in 2008 replacing
MiG-21FL, and MiG-21ML. It is noteworthy, that
the Indian Air Force currently has 19 air squadrons
of MiG-21 aircraft produced on a Soviet license.
A total of 125 MiG-21bis were upgraded to MiG-
21UPG(bison) and the rest, which are both morally
and physically outdated, are to be replace in the
near future.
In 2005, the Indian Air Force concluded a 20
billion rupees (over $445 million) contract with
the HAL for the delivery of the first 20 series
Tejas aircraft Mark 1 with F404-GE-IN20 General
Electric bypass turbofan engines with afterburner,
including 16 single-seat fighters and four twoseat
combat trainers. The agreement also had an
option for the purchase of another 20 aircraft. HAL
ordered a total of 24 F404-GE-IN20 engines costing
over $100 million at General Electric in early
February 2007.
Let us focus on technical features and design
specifications of the Tejas Mk.1 first Indian series
supersonic aircraft.
The light single-engine multipurpose fighter
has the tailless aerodynamic structure with a high
delta wing variable-swept on the fore edge, singlefin
tail unit and one bypass turbofan engine with
afterburner installed at the fuselage rear. The static
stability of the aircraft is reduced. The Tejas features,
the designers claim, are to be as follows:
– high maneuverability;
– multifunctionality;
– all-weather day and night capability;
– compatibility of cockpit instrumental equipment
with night vision goggles;
– low radar echo, which is one third of that of
similar size fighters (that is about 2 m2).
The aerodynamic structure of the aircraft is
claimed to provide minimal wind resistance, little
specific wing load, high rate of turn for bank, yaw and
pitch, as well as good takeoff and landing features.
About 43% of the series-produced LCA airframe
is made of composite materials. The fighter
skin is 90% composite materials. The use of large
coal-plastic panels provided a much lighter design,
as well as a reduced use of fasteners with 5,000 of
rivets necessary compared to 10,000 of a similar
size fighter with an all-metal riveted design. The
use of composite materials saved the necessity of
drilling 2,000 holes in the airframe inevitable for a
usual all-metal design.
The wing is made of composite materials
(longerons, wing ribs and skin), fuselage skin
and air inlets, as well as the elevons, keel, rudder,
and air-brakes and undercarriage flaps. The
coal-plastic skin is 2.4-2.7 mm deep. The airframe
design largely incorporates aluminum– lithium and
titanium alloys.
As a result of implementation of some new
constructional materials (first of all composite
materials) and the latest technologies the duration
of manufacturing period of one LCA aircraft had to
be reduced from 11 to 7 months.

every country inducts jet fighters according to their needs.
we think jf-17 are more than enough for ur mki's.
and our k8 trainers will give lca a tough fight

Yeah yah, Your K-8's are 6th gen aircrafts, It can even bring down F-22.... you guys are the superpower.... No worries....

[flanker143]

tejas mk2 gonna be ready till the production for tejas mk1 ends , and itz goona be ALOT better than tejas mk1

 

[flanker143]

Going by that logic su-30 is a junk as it is inducted by even third world poor countries like Uganda.
And USA's even target plane will be better than the best of uganda.

just to remind u dat pak is also considered to be a 3 third world country dat proves dat jf 17 is junk

and if u sayin that su 30 is junk then jf 17 cannot be called even fighter jet !!!!

yeh induct kab honne walla hain??

as per indian media its in 2014-15.

[farhan_9909]

Any news for you both claims.
speciallly about the FOC by 2013 by mk2?

link for my claim
Tejas LCA project to cost more than Rs 13,000 crore over 35 years - India - The Times of India

india will get 20 tejas by 2014-15

and now plzz dnt say the news is crap or we dnt beleive in TOI
