Naval Tejas Mk1: News & Discussion - 03 January 2020
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
The INSV crew was pleasantly surprised by the ease of operations on deck. The aircrafts was moved below deck for a minor repair. So essentially every aspect has been checked except for arming and disarming onboard
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Hope they release pictures of LCA Navy on the lift and the hangar soon

Only way to win trust and hearts of the Forces is to give then kick-ass products. Good show by NLCA Team.Indranil wrote:NLCA Mk1 has aced the tests. It was not supposed to TO with full fuel in this round of testing, but it did. It seems like TO with full fuel, plus centerline fuel tank and 4 to 6 A2A missiles will be possible. WOW!!!
BTW any plan for night TO/Landing on this test campaign..??
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Cmd Mao had mentioned it in his AeroIndia Seminar a long time back. I dug more to verify what he said was correct because it was against the usually said this what you have said. There is at least one evidence to corroborate his statement. A quote from MoD Reports from early 2000'sKartik wrote:I don't know about that unless you got that from an ADA source...
Design activities on LCA Trainer Variant - LCA(PV5), ensuring commonality with LCA (Navy), has been initiated.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
In the current set of tests as Indranil said above, the plane took off with full internal fuel.srai wrote:mody,
Not possible to meet your specs for a light fighter.
If the NLCA can TO with full internal fuel, 1 centerline drop tank, plus 6 Air to Air missiles, what will be the combat radius of the plane and the maximum on station time?
I would guess with full internal fuel and 1 drop tank the combat radius will be about 350 Kms and on station time of approximately 1.5 Hours or slightly higher. For the Tejas, we know that the combat radius of 500Kms with drop tanks, is on the lower side and actual figures are better.
A combat radius of 300 Kms is a minimum that is required to provide meaningfull air cover to any CBG.
If the NLCA can achieve the above figures, a minimum of 4-6 planes each on board Vikramaditya and Vikrant, would be a good addition to the Mig-29Ks. Plus actual operational experience on board the carrier would provide priceless feedback to the designers, manufacturer and service crew, for future naval fighters.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
How much would a centreline fuel tank add to the weight of the clean aircraft with full internal fuel tanks?
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Weight of fuel is always .75 weight of that much volume of water + gas tank weight.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
It was full fuel if there was missed arrested landing the plane can takeoff and land in goa that was many 100 miles away- per news itself

Would you share how you surmised that ? Chaiwalla or official confirmation ? Good news if so.
If not, I would not hang my hat on the 65kN == full fuel; IMO, unlikely that the first sorties would happen on full internal (vs. sufficient fuel for the test plan)
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
We have no idea that full fuel load took off with 65kN....No way to surmise that.agupta wrote:

we can estimate the TOW must have been somewhere around 10.5T. Likely the Max clean TO or thereabout.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
At least 2 ton weapon/fuel - 1 ton fuel and 3 bvr + 3 wvr- enough for carrier cap with 1:30 hours to 2 hours cap.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Time for HAL to put forth a proposal for naval Tejas mk1a will be in time for vikrant
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Wouldn't combat radius be a variable, rather than a fixed number?
If you want longer radius, you get it by reducing station time. Ofcourse it is always a balance, based on the adequate number of jets you can keep in air against the threat level.
If you have a high availability jet, which you can fly back again after refueling. This would allow you to increase the radius.
Add to this, if the jet is smaller, you can have more numbers on the carrier..

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Not sure if this was posted earlier.. A complete twitter thread describing the meaning of all the symbols on the NLA HUD.

https://twitter.com/Charles_36FS/status ... 5298242560
2/ At the start of the video while the aircraft is at rest, Waterline (denoted by W at the center) is bracketed by ">> <<" symbol. Waterline denotes the exact point at which the a/c's nose is pointing.
Charles Bronson
@Charles_36FS
·
Jan 16
3/ ">> <<" denotes the acceleration/deceleration of the a/c & is therefore known as the acceleration chevron. After take-off, accel. chevron is above the Flight Path Marker (FPM) denoting the LCA is gaining speed with a positive rate of climb.
Charles Bronson
@Charles_36FS
·
Jan 16
4/ FPM can be seen as a tiny circle in the center merging with a long horizontal line extending across the HUD. This is known as 'horizon line'. If the FPM is at the level of horizon line then the a/c is in level flight (not gaining/losing altitude).
Charles Bronson
@Charles_36FS
·
Jan 16
5/ The box with the value 0.00 exactly above the waterline at the start of the video denotes the acceleration of the aircraft at a given level of thrust. It's value rises once the chocks are removed.
Charles Bronson
@Charles_36FS
·
Jan 16
6/ The number on the left denoted by '2.0' is the AoA or the alpha-angle. It measures in degrees the difference between the direction at which a/c's nose is pointing (denoted by waterline) & the flight path of LCA (denoted by FPM).
Charles Bronson
@Charles_36FS
·
Jan 16
7/ Note the sharp rise in AoA once the pilot pulls up after exiting the ramp. 63.2 KN on the bottom left denotes the level of thrust generated by LCA.
Charles Bronson
@Charles_36FS
·
Jan 16
8/ The number at the top left is the Calibrated Air Speed in knots, the tape in the top center is the magnetic heading tape & the number on the top right is the barometric altitude in feet. After LCA is airborne, the box with acceleration value in the center disappears.
Charles Bronson
@Charles_36FS
·
Jan 16
9/ It is replaced with an up-arrow on the right side of waterline with a value which denotes the a/c's current rate of climb. ">> <<" denotes acceleration. Also the number just below the waterline after take-off denotes the radar altimeter value of the aircraft.
Charles Bronson
@Charles_36FS
·
Jan 16
10/ Once LCA is airborne, a 'I' shaped bracket appears on the left of waterline. This is the AoA bracket- pretty darn useful while landing & also denotes the gear is down.
Charles Bronson
@Charles_36FS
·
Jan 16
11/ G force is indicated by the number on the left between AoA & the engine thrust, appearing soon after LCA is airborne. After take-off, there are two numbers on the top right, situated above one another.
Charles Bronson
@Charles_36FS
·
Jan 16
12/ They denote the altitude of a/c, top being the barometric altitude; bottom one being the radar altitude with 'P'. On the bottom right you have waypoint information (distance & time to next waypoint).
Charles Bronson
@Charles_36FS
·
Jan 16
13/ The pentagonal box which appears in the center of HUD after LCA is airborne possibly denotes the nearest waypoint.

Doubt it since so many HUD videos are available in the public domain from all airforces across the worldCybaru wrote:Isn't HUD symbology heavily guarded for some reason?
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
This is a symbology for take-off which was released. Reason could be to show the capability to certain "dushman nations". By itself it is benign. Since they have not released it for landing and definitely not for ops and other roles.Cybaru wrote:Isn't HUD symbology heavily guarded for some reason?
With this, it is evident that NLCA can take off with 2.5 tonnes of stores. Not bad at all. With proper optimizations it can do 3 tonnes.
That is why I am votary of inducting 1 squadron of NLCA. Move on to NLCA Mk2 with GE-F414 and redesigned placement of landing gear to optimize on hardpoints. That will give it very decent 4-5 tonnes and a larger combat radius. If it can carry 3 Brahmos-NG and 2 CC WVR, it will be a deadly package. Any other Carrier group will have to now have a minimum stand off distance of 1000 Km from Vikramaditya.
Hence we should go for NLCA Mk2 (2 squadrons). After that we should look at TEDBF - which is a paper plane. But a good step forward before NAMCA.

Should have got ready for the photo op. I am sure the program manager requested and the crew told him to get lost. I know them well. Optics is not their game.

how anyone can complain about the uncleanliness of the aircraft versus the beauty of the photo is beyond me.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Yes,if the money is there one sqd. of the NLCA could complement the 29Ks in a meaningful manner.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020

It would be short sighted to not order a squadron of the NLCA. Hopefully good sense will prevail.

There are idiots out there who say that the airplane is rusty and not well maintained.Rakesh wrote:how anyone can complain about the uncleanliness of the aircraft versus the beauty of the photo is beyond me.
That is the level of some of the folks out there commenting on things they haven't the foggiest idea about. If that person visited an air base and saw some of the older jets, he'd have a heart attack. Those jets are all flying fit, but not necessarily scrubbed down and polished like a USAF Thunderbirds jet because that really isn't that important for them.
