This is the same thing which Vijay kumar Saraswat had said. Another 8% Aerodynamic improvement shall come from proposed aerodynamic changes of cockpit elevation. We may expect a very nice aerodynamic characteristic from Tejas post 2017. It will accelerate fast, it will have a better speed, more fuel efficiency and performance as well. Tejas is improving very fast.

tejas has landed, after her flying display

the commentators said it was a terrfic performance.

NIce performance on the second day for Tejas in Bahrain

 

[punjab47]

Any youtube link for second day? Have link for first from some sullah channel where it's britshit english but spitting sister fuckin arabic sounds.

Pretty cool maneuvers but, turn rates look a bit low. Will be excited to see 3-800kg lighter 5-10% more aerodynamic MK1A; & then there's mk2 with stronger engine.

Full-scale production of LCA Tejas by next year: Manohar Parrikar

We will have total 20 Tejas Mk1 & 100 Mk1-A on order as of now.

However am concerned with HAL delivery timelines. They do not match promise.

till March-15: SP1 (Handed over to IAF)
Apr-15 to March-16 : SP2 (Expected to be handedover but Only one LCA is expected to be produced in this 1 year ?)
Apr-16 to March-17 : SP3 - SP?
Apr-17 to March-18 : SP? - SP?
Apr-18 to March-19 : SP? - SP?

Can someone having idea, please update this with source of information.

ANd peak Gs pulled to evade a air to air missile mostly tops out at 8Gs and tejas with 8gs is okay for that.--"The mean peak + Gz in most air combat situation was 6.73 G with a range of 5.54 to 8.03 G ."

'The maximum onset rate ranged from 1 to 4.7 G/s with a mean of 2.54 G/s. The average maximum offset rate was 2.2 G/s with a range of 1 to 3.96 G/s. This is comparable with the maximum onset rates of other ASFs of IAF. Previous studies [5, 6] have documented a maximum onset rate of up to 3.83 G/s for Mig-29 and 5.51 G/s for Mirage 2000 aircraft. Thus the aircrew of ASFs of IAF are exposed to very high rates of onset of acceleration during specific combat missions.'

Analysis of the Gz profile during ACM revealed that the aircraft crossed 6 G in 83% and 7 G in 36% of combat situations. Further it was found that the pilot spent a mean duration of 3.65 sec between 6 G and 7 G, while he spent 2.12 sec above 7 G (Ref Table 3).

Even though the aircraft is capable of pulling high sustained G (7G 15 sec or 8G 10sec) and all it’s pilots have been trained in the IAM centrifuge to hack HSG, such high G load was not observed in this study. This can be explained on the basis of better manoeuvring capabilities and advanced missile launch envelop simulated by the aircraft.


The aerodynamic configuration and TVC capabilities along with a highly effective digital FBW system allows the aircraft to manoeuvre at very low speed, in very less airspace and in a very shorter period of time. This along with an advanced radar and better missile envelope allows the aircraft the ease of achieving the position of advantage, thus explaining the lesser duration of time spent at high Gz levels.

Are levcons only for naval variant?
I wonder what Teja?n do with GE 414 ins6 engines. IN will definitely order atleast 50 Tejas. But will it have wing folding capability for carrier operations

Introduce yourself by creating a thread in Introductions and Greetings Section.

Thank you sir, I will...............

tejas has very short wingspan, It wont need folded wings

 

[Bangalibaba]

Nope. Only Su27 and further developed fighters can do. (Not even F-16, F-18, Rafael etc..)

FYI.. not sure whether photoshopped video or not but 'Bandar' doing a vertical take off at Paris Air Show 2015

guys can anyone give me the full form of DSI and explain in few lines

Tejas doing aerial ballet in Bahrain air show. (Good quality video)

Thanks a lot

The Tejas will also carry IMI's PB-500.

Congratulation ADA Tejas team, Indian Airforce test Pilots for great show at Bahrain.

I noticed on an anti India forum many butt hurt neighbors are inventing lies and paddling Lahori science bullshit while analyzing Tejas performance. However Indian have beaten them into pulp with logic and rational counter.

Interestingly mighty JF17 Thunder is having long mensuration period this month. The sanitary pads had to come all the way from China therefore the jet was officially pulled out of the show.

Will the proposed 120 Tejas for airforce will all be with GE404IN20 engines?
Are we buying GE414INS6 only for navy?

Yes, Mk1(20) & Mk1-A(100) will have GE404IN20.

Tejas Mk2 for IN & IAF will have GE414INS6.
