Active Electronically Scanned Array Radar (AESAR)
‘Uttam’: AESAR ‘Uttam’ is an airborne fire control radar
for our indigenous fighter aircraft LCA ‘Tejas’. It is a
multi-mode radar which can be configured for fitment
on different airborne platforms. Shake down sorties
were completed in January, 2019 on modified executive
Jet hired. Indigenous AESA radar integration and EMI/
EMC tests on LCA ‘Tejas’ LSP2 aircraft are nearing
completion and flight evaluation is planned shortly.
Land Based Prototype (LBP) for Air Independent
Propulsion (AIP): DRDO is involved in the development
of indigenous technologies for the development of a LBP
for AIP system for Indian submarines in collaboration
with M/s L&T, Mumbai as Lead System Integrator (LSI)
and other industry partners viz. M/s Thermax, Pune and
M/s Centre for Development of Advanced Computing
(M/s CDAC), Thiruvananthapuram. The successful
development of the LBP will ultimately lead to realization
of fuel cell based AIP for P-75 class (Scorpene) submarine,
which would result in additional underwater endurance
of the submarine at nominal power consumption level.
It aims to package the AIP plant sub-systems, reactant
tanks and waste tanks inside the simulated hull section
of the P-75 submarine. During the period (January, 2018
– March, 2019), all piping modification design/drawing
were completed and approved. Equipment mounting
and hull modification was also completed. Endurance
mode trials are expected in June, 2019.
System Definition & Engineering of DRDO AIP System
on P-75 Submarines and Development of Deliverable
LOX System: The primary objective of the project is
to develop the optimized design of Phosphoric Acid
Fuel Cell (PAFC) system, hydrogen generators, power
conditioners, control systems, heat exchangers, DM
water system and auxiliaries of AIP system and qualify
the same for P-75 platforms. The project is progressing in
collaboration with M/s DCNS France. During the period
(January, 2018 – March, 2019), major safety reservation
data was submitted and accepted. Naval Group France
cleared all blocks and declared sufficiency to take-up
detailed design phase.
Advance Light Towed Array Sonar (ALTAS): ALTAS is an
efficient sensing system for detection, localization and
classification of submarines operating especially in the
below surface layer ocean conditions. It is useful in Anti-
Submarine Warfare (ASW) operations and is the apt
sensor for warships to locate silent submarines capable
of launching high speed torpedoes. User Evaluation
Trials of the system onboard INS Sharda has been
completed satisfactorily.
Medium Altitude Long Endurance (MALE) Unmanned
Aerial Vehicle (UAV) ‘TAPAS BH’: TAPAS-BH, a multimission
UAV is being developed with an endurance
of 24 hours to carry out the intelligence, surveillance
and reconnaissance (ISR) roles for the three Armed
Forces. It is being designed to operate at 30,000 ft
Above Mean Sea Level (AMSL) altitude and is capable
of carrying Electronic Warfare and Electro-Optic &
Synthetic Aperture Radar (EO & SAR) payloads. It can
carry a variety of other payloads weighing up to 350 kg.
The flights with High Power Engine (HPE) commenced
in February, 2018. During January, 2018 – March, 2019,
39 flight trials using airframe AF5 (with HPE) have
been completed (total 50 flight trials completed since
the maiden flight in November, 2016). Flight trials on
airframe AF6 also commenced in January, 2019 and as
on date, 9 flight trials have been conducted. Indigenous
SATNAV INS system, indigenous payloads (GPA Mk-IV,
MREO) and imported payloads (SATCOM, LREO, ELINT&
SAR) has also been tested during these trials. The
payload was able to localize radars successfully.
