The indigenously built Light Combat Aircraft Tejas LCA Navy
NP1 today made its maiden flight in Bangalore when Commodore JA Maolankar, Test
Pilot and Wg Cdr Prabhu, Flight Test Engineer completed a 22 minutes flight.
During the flight the aircraft was put through various manoeuvers
including low speed handling and even undertook a close formation flying at
slow speed with another aircraft.
Earlier the LCA Navy NP1 had completed various intensive
Ground testing regimen including Low Speed Taxi Trials (LSD), High Speed Taxi
Trials (HSD), Ground Vibration Test (GVT), Structural Coupling Test (SCT) and
extensive system integration tests with power plant using State-of-the-Art
facilities at Bangalore HAL airport.
With this India has crossed a major milestone in Design,
Development, Manufacturing and Testing of a “four plus” generation Carrier
Borne Fly-by-Wire STOBAR aircraft.
LCA Navy aircraft is the first attempt in the country to
provide a complete marine force multiplier that will give unique battle punch
to the Naval Aviation Arm of the 21st Century to fulfil national dream of a
blue water Navy. LCA Navy is the second STOBAR (Ski Take Off But Arrested
Recovery) Carrier Borne aircraft in the world, after the Russian deck based
aircraft. However, this will be the only Carrier borne Fighter aircraft in the
Light category.
Along with Hindustan Aeronautics Ltd (HAL) who are the
Principal Partners with Aeronautical Development Agency (ADA) in association
with more than 100 agencies ranging from users, DRDO, CEMILAC, DGAQA, CSIR,
PSUs, Private Industrial Sector and academia, spread all over India including
Indian Navy and Indian Air Force are involved in the Programme. The key
responsibility of LCA Navy design, build, integration and testing is with
various Divisions of HAL. ADE has played a lead role in Design and Development
of the Integrated Flight Control System in unison with NAL, Bangalore for
Testing and Integration of Flight Control Laws to ensure safe functionalities
for various phases of flight. AMAGB has been designed and manufactured by
CVRDE, Chennai up-to the certification level. NSTL, Visakhapatnam and RCI,
Hyderabad has rendered critical support for shock testing of LRUs. Significant
Private Industry partnership with ASL (DRDO), Hyderabad for high energy
Carbon-Carbon brake pads, and CADES for LEVCON and stub wing design, as
examples, has helped maturing of Private Sector of the country. This Project
will give us self reliance capability in a true sense and also help in taking
up more Naval Aircraft Projects in future. Productionisation of indigenously
developed Hydraulic system and Fuel system Line Replacement Units (LRUs) have
been assigned to GTTC, Bangalore (Government Tool Room and Training Centre) and
CTTC (Centre Tool Room and Training Centre), Bhubaneswar respectively. Above
all this, constant support, regular participation, keen observation and
continuous guidance from CEMILAC and DGAQA have ensured stringent certification
and quality requirements are met on the aircraft.
The Design of first indigenous Naval aircraft imposed huge
technological challenges to the Defence Research & Development Organisation
(DRDO) to meet the peculiar requirements of Naval aircraft; starting from
saline and humid environment of operation, restricted availability of deck run
for launch and recovery and high operating load conditions. Basic design
changes required to suit the carrier operations are strengthening of aircraft
structure and Landing Gear, Arrester Hook, improved engine, enhanced
aerodynamic performance and incorporation of special metal/material. A host of
other systems like the Leading Edge Vortex Control (LEVCON) surface fitted at
the front end of the aircraft wing operated by a concealed rotary actuator with
aerodynamic profiling to ensure low landing speed, good controllability and
better vision for the pilot. The feature of launch and recovery onboard Carrier
at high sink rate of 7.1 rn/sec, flareless landing with engine to full throttle
till arrested by deck cable impose five times of loading on Main Landing Gear
as compared to the IAF version. Also such axial load calls for re-certification
of all Line Replacement Units (LRUs), components and associated systems of
naval version to ensure fail safe operation repeatedly.
ADA has set a world class Telemetry and Monitoring facility
at the National Flight Test Centre (NFTC) to enable conduct of flight test
activities at Bangalore. Intuitive on-line monitoring and control of the
aircraft are carried out by the Test Director and various System designers. To
facilitate proving the aircraft for carrier borne applications, a Shore Based
Test Facility (SBTF) is being set up at the Naval Air Station, Goa replicating
an aircraft carrier with a ski-jump for launch and arresting gear for deck
recovery. Take off area is ready, with landing readiness scheduled for end of
2012. This test facility readiness is as per schedule.
The Chief of Naval Staff Admiral Nirmal Verma in a
communication to the Scientific Adviser to the Raksha Mantri, said, “… I
express my appreciation and congratulations to all members of the ADA, HAL and
DRDO teams for the first successful limited test flight of the LCA (Navy)
aircraft… We must ensure that today’s accomplishment leads to the timely
fructification of the operational requirements for carrier borne operations….”
