Infrastructure Facilities

CASDIC has developed a Range On Wheels (ROW) facility for evaluation of airborne EW systems. Range can be used for Avionics, Weapon and EW systems test and evaluation. Presently the range is used by DRDO, Defence Services (Air Force, Navy and Army), M/S HAL and M/S BEL. The range can be offered to the civil industry to test their products on requirement basis.

Sangam is built on a 40 feet trailer, has four independent cabins and a service bay which houses support facilities. SANGAM provides laboratory environment and houses data acquisition systems, data analysis facilities, real time telemetry, communication, video recording and displays.

Sanchalika is a Mission Control Vehicle, where all the activities of flight trials can be monitored and directed. It has a unique configurable display system, using which effecive presentations can be made

Dasa is a slaved pedestal system comprising of a servo pedestal, a transmitter antennae, transmitter system, a receive antennae and receiver system. The servo pedestal is slaved to one of the tracking radars. This station will facilitate radiation of programmed threat signals towards the EW aircraft under evaluation and also in the measurement of RF power from the on-board ESM systems.

Shakthi vehicle houses a 100KVA, 3 phase generator system and the power is routed to the other vehicles through a power distribution system.

HALT/HASS Test Facility

CASDIC has established HALT/HASS Test Facility in the year 2011, this facility comprises of a Chamber, Air compressor and LN2 storage tank and is used to conduct accelerated temperature and vibration tests on modules and subunits of systems under development. HALT is used at the design stage of a project to quickly expose the weak points of a design so that the product can be re-designed to remove these weak points, thereby expanding the margins of the design. HASS is used at the manufacturing stage of a project to quickly expose any manufacturing flaws that a particular sample may have. The two principle stresses used during HALT and HASS are rapid temperature transitions (-100º C to +190º C) and 6 degrees of freedom (DOF) random vibration max 60grms.

Highly Accelerated Life testing (HALT) and Highly Accelerated Stress Screening (HASS) are special types of accelerated reliability testing techniques that are very effective and are being used world-wide. HALT is used at the design stage of a project to quickly expose the weak points of a design so that the product can be re-designed to remove these weak points, thereby expanding the margins of the design. All of this can be achieved at a minimal cost increase, if any at all. HASS is used at the manufacturing stage of a project to quickly expose any manufacturing flaws that a particular sample may have. Both the techniques rely on the time compression concept and use much higher stresses than experienced in the field environments to force failures to occur in significantly less time, thus it eliminates the design and process problems before the items are released for development or production. The two principle stresses used during HALT and HASS are rapid temperature transitions and 6 degree-of –freedom (DOF) random vibration. This test facility includes an exclusive test chamber with six degree-of-freedom vibration table and capable of producing very high temperature ranges with high ramp rates.

Laboratory Cooling System & Ground Support Equipment

In order to handle high thermal loads generated by high power electronics, several compact cooling systems ranging from forced air cooling to closed loop liquid cooling have been developed and flight-proven.<

Automatic Test Equipment (ATE)

The EW suites developed in CASDIC have RWR, internal jammer and podded jammer. ATE is designed to test all line replaceable units (LRUs) and associated PCBs. It consists of GPIB-based test instruments, ISA bus-based PC add-on measurement cards and custom interface units. Desktop computer serves as the ATE controller. The controller communicates with test instruments via GPIB interface bus and with LRUs via RS-232 and RS-422 serial lines.

The test software is windows-based with excellent graphical user interface. The software is enabled, for conducting the functional tests on LRUs and PCBs, through password protection and provides following additional facilities:

Dynamic Avionics Integration Rig (DAIR)

DAIR for LCA is used to carry out extensive testing of all the functions of the aircraft on the Rig. This facilitated in successful of LCA and the Rig is now getting updated for LCA. Termed as Flight-On-Ground, this facility is now developed for the fighter aircraft upgrade programme for testing all the avionics interfaces and avionics integration. Successful flight testing of fighter aircraft with upgraded avionics was possible due to rigorous testing carried out with the help of this facility.
