Naval LCA Tejas

[Jagdish58]

I had read that NAVAL LCA flies better than airforce tejas. Does anybody has any idea about it? We observe a phenomenal climb rate in ski jump at goa? Does it have a better aerodynamics than Airforce tejas? What roll does wing root lavcon play in its performance?
@ersakthivel

Even ADA & NAVY were surprised by NLCA performance , yup the aerodynamic change & adding of Levcon which gives advantage of having canard like feature in high angle of attack , climb & slow decent while landing without compromising on stealth features of aircraft

Currently only NLCA & PAKFA has LEVCON non other

3.3 Sustained Turn Rate Improvement using Levcon:

Leading Edge Controller (Levcon) is an secondary control surface located at the leading edge of the wing and the fuselage. The Levcon is initially planned in LCA Navy for the low landing speed capability and other cruise performance. An important requirement of a fighter aircraft is the Sustained Turn Rate (STR). The fighter variant of Tejas is not meeting the STR requirement of ASR. The STR is a strong function of the aerodynamic efficiency. From the wind tunnel results it was found that the Levcon produce higher L/D (Fig. 17). A detailed study to implement Levcon in fighter and identification of other design constraints is under progress.

HAL has capacity to produce 8 LCA Tejas per annum: Manohar Parrikar


HAL and DRDO have always maintained that the technology in Tejas will not go obsolete for quite some years. It has also intentionally been made longitudinally unstable. This is meant to enhance the aircraft's maneuverability.

Manohar Parrikar in his reply also said that there is no fighter aircraft project which is pending for decades. According to Parrikar, Tejas will help partially meet IAF’s requirement of light weight fighter planes. (PTI)

Hindustan Aeronautics Limited (HAL) has the capacity to produce eight Light Combat Aircraft (LCA) Tejas per annum, said Defence Minister Manohar Parrikar in a written reply in the Rajya Sabha today. Earlier this month, the Indian Air Force (IAF) inducted the indigenous Tejas aircraft.

IAF raised the first squadron of Tejas with the induction of two LCA Tejas and plans to the aircraft in combat role as early as 2017. Manohar Parrikar in his reply also said that there is no fighter aircraft project which is pending for decades. According to Parrikar, Tejas will help partially meet IAF’s requirement of light weight fighter planes.

Tejas is said to be smallest lightweight, multi-role single-engine tactical fighter aircraft in the world. It is also highly agile and is a multi-role supersonic fighter. The LCA, which has been several years in the making, boasts of a quadruplex digital fly-by-wire flight control system.

HAL and DRDO have always maintained that the technology in Tejas will not go obsolete for quite some years. It has also intentionally been made longitudinally unstable. This is meant to enhance the aircraft’s maneuverability.

The combat aircraft uses fourth generation technologies. Incidentally, Tejas has also caught the attention of foreign buyers with Sri Lanka and Egypt evincing interest in the indigenously built fighter jet.

Tejas has been developed in multiple variants – single-seat fighter and twin seat trainer variants – for IAF and Indian Navy. Swedish defence major Saab is in talks with HAL for helping India make the next generation version of the LCA Tejas.

When in NP3 suppose to show up? Also what are the improvements is it suppose to bring with it? Lighter landing gear, GE 414?

LCA Naval Tejas

Can any of you tell me how does naval LCA compares to Airforce tejas so far as aerodynamics is concern? Why did it struck a very high lift ratio over 10 against anticipated 5 ? What is the impact of wing root lavcon? Is there any wight reduction in landing gear compared to MK1? People says that it can land at a much lower speed compared to MK1. Is it true? If so why and how?

 

[Prashant12]

The image is of the Naval LCA from the recently concluded trials at the Shore Based Test Facility, GOA. The exercise was quite fruitful looking at the effort and objectives achieved. The carrier suitability exercises is a different ball game all together where we as a nation trying to bridge the gap of understanding and flight testing of decades over one program and and two prototypes. Therefore, the technology has to be the top notch and must assist the flight crew consisting of flight test engineer, test pilot and the LSO (normally a pilot on ground who guides the pilot in the cockpit to the arresting cable on the deck). We wish the flight test team a fruitful and event free testing phase ahead.

It has been 7 years since this paper was published. Still there is no LAVCON, no Cock pit elevation, no Nosecone plug. There are only studies and no improvement. One more paper has come in claiming 8% Aerodynamic improvement and 20% rise in transsonic acceleration etc. I do not know when will they implement all this?

 

[Prashant12]

In a defining moment for Indian Naval Aviation, the First Prototype (NP1) of Naval Light Combat Aircraft (LCA), the first indigenously designed and developed 4th plus generation combat aircraft designed to operate from the decks of air-craft carriers, had its successful first flight at HAL Airport in Bengaluru in 2012.

Just need 25 years to replace Mig 21 fleet.....

Just need 25 years to replace Mig 21 fleet.....

And you don't know that HAL started doubling the rate of production ever since it received firm order of 100 fighters. There is even a plan to triple the present rate of production once Naval version enters production.

Rate of production is directly proportional to numbers ordered.

"HAL has submitted a proposal to the Defence Ministry to ramp up the rate of production from eight aircraft to 16 per annum. HAL is planning to establish the facilities within three years from the date of approval."

Yup we have liberty to take even 10 more years do you have any problem?? worry about Rafake deal

Absolutely no problem for me. It's an Indian, and only an Indian problem.

The embarked Indian Navy MiG-29K accumulate deficiencies
Learn more about http://www.opex360.com/2016/08/11/l...cumulent-les-deficiences/#0psXw7OCB9TKdGQM.99

After, in 2015, lamented the low combat aircraft availability rates Su-30 MKI of the Indian Air Force, the "Comptroller and Auditor General '(CAG, the Indian equivalent of the Court of Auditors) has examined the shipborne aircraft MiG-29K for the Indian navy. And the findings of his latest report are not very good ...

Thus, the CAG denounces that the first MiG-29K delivered (45 on order for $ 2.2 billion) were accepted despite technical defects. Clearly, the aircraft did not conform to what was expected by the Indian Navy.

In addition, the CAG also advanced, many problems and defects concerning not only engines but also the cell and electric flight controls of MiG-29K service.

Remember, these devices are operated from the aircraft carrier INS Vikramaditya (formerly Admiral Gorshkov), a ship purchased from Russia and comes with 4 years late, with the bonus of a past invoice 947 million to 2 billion.

However, the Indian Navy had the choice between the MiG-29K and Su-33, two Russian-designed aircraft capable of evolving from an aircraft carrier in stobar configuration (Take-Off Short But Arrested Recovery).

Anyway, this CAG report sparked acid comments from Admiral Arun Prakash, a former Chief of Staff of the Indian Navy. "The causes of these problems [those of Indian MiG-29K, note] are from very poor quality control in the Russian military-industrial complex and the lamentable support made of Russian industry in the Indian Navy," Has -he felt in the columns of DefenseNews.
According to the CAG report, 62% of engines for MiG-29K were either already removed from service or denied because of design flaws. "The engine design flaws must be corrected as soon as possible, at the expense of the Russians. Any respectable company, aware of its reputation would. But the oligarchs who control the military-industrial complex are too cheeky because they know that India has no choice and are confident that Indian politicians will never tell them anything, "railed the Admiral Arun Prakash.

Yup then why the hell you quote 25 years etc crap? Are you all right

Just need 25 years to replace Mig 21 fleet.....

Even the 36 about to be ordered will take 3-4 years or more to deliver .. that more or less equates to about 8-10 a year capacity .. that's from a optimised supply chain..

HAL on the other hand is just developing a steady supply chain Don't understand what your coming to imply with your 25 year comment

 

[Yumdoot]

HAL made 20 Sukhois last year.

Additionally the LCA line is coming up entirely separate from the Sukhois. Currently at 8 per year but the investment plans for increasing that to 16 per year are going to be passed.

Should be enough.

 

[Rahul Singh]

But in no case Rafale M will fly in Navy. That's for certain.

Interesting orientation of the front canards.

I see some pictures of the N-LCA with the canards pointed upwards.

I wondere how they affect the maneuverability of the aircraft.
