LCA Tejas Notches Up Crucial Cold Start Test Point

 

January 28, 2015 by Livefist

 

Some good news in from the Tejas Programme currently fighting to finish high-altitude cold weather test points in Leh, Ladakh. Here's the full DRDO statement just in: [With] three consecutive start-ups of its engine after overnight soak in extreme cold (around -15ºC) conditions of Ladakh, that too without any external assistance, Tejas, the Indian Light Combat Aircraft has achieved yet another and a rare distinction. Starting the fighter aircraft under such extreme condition without any external assistance or heating is a technology challenge. The requirements become further stringent when the starting is to be done three times consecutively with a partially charged battery. Team LCA led by AERD&C of HAL, and members from ADA, NFTC, IAF, CEMILAC and DGAQA have succeeded in achieving this. “The team LCA has achieved a technological breakthrough”, stated Dr. PS Subramanyam PGD (CA) & Director, ADA.

 

LCA Tejas Notches Up Crucial Cold Start Test Point

The engine starter is developed indigenously by HAL Aero Engine Research and Design Centre (AERDC), Bangalore. Prior to aircraft tests, the Jet Fuel Starter (JFS) was extensively tested on test rig to meet starting conditions across the operating altitudes including Leh (10,700 ft.) and Khardungla  (18300 ft.). The control software of JFS was fine tuned to work at all operating altitudes with no adjustments from cockpit. GE-F404-IN20 engine start up control schedule was also varied with several control patches to establish reliable [start].

The first prototype of the naval LCA Tejas, NP1, blasted off the shore-based test facility (SBTF) at the INS Hansa naval air station in Goa today, kicking off the next phase of testing on the country's first naval combat aircraft platform. The National Flight Test Centre's Cmde TA Maolankar flew the jet on today's sortie that involved only a ski-jump take-off but a conventional landing. Arrested landings till take place in the second phase of SBTF test flights.

 

FULL OFFICIAL STATEMENT: It was a defining moment when LCA (Navy) Prototype 1 (NP1), the first indigenously designed and developed 4th plus generation combat aircraft designed to operate  from the decks of air-craft carriers, took-off majestically from Ski-Jump facility of Shore Based Test Facility at INS Hansa in Goa at about 12:34 PM today the 20th December 2014.

 

Piloted by Commodore Jaideep Maolankar, the Chief Test Pilot of National Flight Test Centre, the aircraft had a perfect flight with results matching the predicted ones to the letter. The launch was orchestrated by the Test Director Cdr J D Raturi and Safety Pilot Capt Shivnath Dahiya supported by Gp Capt Anoop Kabadwal, Gp Capt RR Tyagi and Lt Cdr Vivek Pandey. The readiness and availability of aircraft for the event was made possible through the relentless effort of HAL, ARDC under the aegis of Mr P S Roy the Executive Director.

 

Dr Avinash Chander, SA to RM, Secretary DDR&D DG DRDO congratulated the LCA Navy program team and said, "With today's copybook flight of LCA-Navy from the land based ski-jump facility we see our own indigenous combat aircrafts soon flying from the decks of our aircraft carriers.” Congratulating the team Dr Tamilmani, DS & DG Aeronautics, said “A complex task of Ski Jump of NP1 Executed beautifully”.

 

LCA (Navy) is designed with stronger landing gears to absorb forces exerted by the ski jump ramp during take-off, to be airborne within 200 m as against 1000m required for normal runways. It’s special flight control law mode allows hands-free take-off relieving the pilot workload, as the aircraft leaps from the ramp and automatically puts the aircraft in an ascending trajectory. The maiden successful, picture perfect launch of NP1 from ski jump at Shore Based Test Facility at Goa is a testimony to the tremendous efforts put in by scientists and engineers to design the Naval aircraft, its simulator (that helps pilots to know well in advance how the aircraft will behave on ski jump) and the flight test team that timed the whole event to near perfection. It can be stated with conviction “The indigenous Indian Naval Carrier Borne Aviation program has been launched, literally from the Ski-Jump".

 

The LCA Navy program team of ADA (Aeronautical Development Agency) is jubilant on achieving the remarkable feat that is the culmination of several years of design, flight test, simulation and management effort with significant contributions from a number of DRDO laboratories. The teams were ably supported by the certification agency, CEMILAC and the quality assurance agency, CRI (LCA). INS Hansa, the Naval Air Station played the perfect host to achieve this significant milestone. The design teams guided by Program Director ADA Shri P S Subramanyam have ensured that all systems meet the stringent requirements of Carrier borne aircraft. Cmde C D Balaji (Retd) as Project Director LCA (Navy) and it’s Chief Designer has been at the helm of affairs right from the concept phase. The team led by Dr Amitabh Saraf indigenously achieved the flight control laws that take care of the problems encountered by a fly by wire aircraft undertaking a Ski Jump Launch.

 

The Shore Based Test Facility (SBTF) has been created to replicate the aircraft carrier with a Ski Jump for take-off and arresting gear cable for arrested landing; by ADA with the participation of the Indian Navy, Goa shipyard, CCE (R&D) West, Pune, R&D Engg (E) Pune and the Russian agencies providing the design support and specialized equipment.

The Defence Minister Shri AK Antony today expressed optimism that the country’s indigenously developed fighter aircraft- LCA TEJAS- will get Final Operational Clearance of the Indian Air Force by the end of next year. Speaking at the Annual Awards Functions of DRDO here, he said, all stakeholders including the DRDO, IAF and HAL must put their energy together in a focused manner to achieve this objective. 
 
Shri Antony said countries that depend on imported arsenals cannot become great nation. Shri Antony said we continue to be the largest importer of Defence equipment. The share of indigenous content in Defence procurement is low. “Our experience has been that foreign vendors are reluctant to part with critical technologies. There are delays in the supply of essential spares. There are exorbitant price increases. The Services too realize that we cannot be eternally dependent on foreign equipment and platforms”, he said. 
 
Referring to the expansions of domestic defence industry, Shri Antony said this has to be achieved through public and private sector initiatives. He said there is ample scope for joint ventures also. “All the stakeholders in the defence sector- DRDO, Armed Forces and the industry must work in tandem and develop trust and confidence in each other’s capabilities.” Cautioning against time and cost over runs in projects Shri Antony said Indian Companies must compete with global players in developing state- of- the art technologies of acceptable commercial parameters and must meet customer satisfaction. 
 

 

The Minister complimented DRDO for their magnificent achievements in 2012. He referred to the first flight of Agni-V, two successful tests of our Ballistic Missile Defence programme in February and November 2012, first flight of LCA Navy, establishment of a cyber-forensics laboratory, initiation of production of NBC systems, ToT for composite armour for helicopters and investment casting of aero engine components and said these are just some of the many accomplishments. 
 
He, however, asked the scientists not to be complacent. “The DRDO must keep its focus trained on the areas of core competence and not fritter away its energy and resources. In today’s world of cut-throat competition, the choice is very clear-‘perform, or perish’. From designing stage to the stage of final production, timelines must be strictly adhered to and satisfaction of the end user is the litmus test of achievement”, he said. 
 
He said, the security environment in our neighbourhood; civil strife and turmoil in the Middle East; terrorism and threats to cyber security; piracy; illegal seabed mining in Indian Ocean and space-based threats present complex challenges to our defence capabilities. These require both conventional, as well as latest technological responses. 
 
Expressing happiness the Minister said, it is heartening to note that a large number of major systems are under production and the cumulative production value of all the DRDO developed systems has crossed Rs. 1,55,000 crore. ‘I am sure in the coming years, this figure will go even higher. DRDO must make relentless efforts to accelerate the pace of self- reliance’, he further said. 
 
The function was attended among others by the Minister of State for Defence, Shri Jitendra Singh, Chief of Air Staff Air Chief Marshal NAK Browne, Chief of Naval Staff Admiral DK Joshi and Director General DRDO Dr. VK Saraswat. 
 
On the occasion, Shri Antony gave away DRDO Awards to several scientists, technologists and DRDO laboratories in fourteen categories for their outstanding contributions in different areas.
