DARE completes IAF MiG-27 upgrade
Defence Avionics Research Establishment under the aegis of Defence Research and Development Organisation achieved the successful completion of avionics upgrade of MiG-27 aircraft. This pioneering effort was realised using entirely indigenous expertise at a fraction of cost. The project was initiated in the year 2002 through a tripartite MoU between DARE, HAL(Nasik) and Air Force. The Initial Operational Clearance was accorded in June 2006 which led to the subsequent formation of operational squadrons.
The avionics system is built around a modular mission computer termed Core Avionics Computer (CAC), developed by DARE. The CAC built on open system principles, houses functional modules using contemporary processors and devices. These functional modules are powering the mission computers on Jaguar and Su-30 MKI aircraft as well.
The upgraded MiG-27 aircraft is equipped with Inertial Navigation & Global Positioning System (INGPS) providing accurate Navigation. Advanced avionics on the aircraft has been interfaced on MIL-STD-1553B Dual Redundant Bus. To enable weapon aiming, accurate ranging sensors such as Laser Designator Pod (LDP) and Laser Ranger & Marked Target Seeker (LRMTS) are integrated. A digital Map Generator has been integrated to improve situational awareness. The digital Video Recording system provides mission analysis and debrief support.
DARE took up the challenge of developing the mission critical software. Over half a million lines of code were developed adhering to stringent real time constraints and requisite software engineering requirements. The resultant quality software was independently verified and validated with external agencies. DARE developed algorithms for navigation, ranging including a weapon delivery algorithm which was developed along with Software Development Institute of Air Force enabling precision Weapon Delivery.
The upgraded aircraft has a pilot friendly cockpit with state-of-Art Multi Function Display (MFD) and Head Up Display (HUD). The pilot flies "Head Up" with all the necessary NAV and attack guidance symbology presented on the HUD and superimposed on the outside world view. The Integrated Flight and Weapon Control System of the upgraded aircraft enables Hands Free (Auto Pilot) Route Flying and Auto-Weapon delivery. A functional maintenance mode has been incorporated providing "On AIRCRAFT" LRU health checks.
Advanced integrated EW Suite is integrated along with state-of-art communication systems. The upgraded aircraft also has an emergency situation indication system and automated emergency handling cueing system on Multi Function Display (MFD). The introduction of LDP has enhanced the Night Attack Capability. HAL, Nasik was instrumental in the design and modification of prototype aircraft for installation of new cockpit and avionics equipment as well as related looming changes.
The avionics upgrade has transformed the legacy aircraft into a potent weapon delivery platform with a user friendly cockpit. All the aircrafts have been upgraded and the users are enamored with the performance of the upgraded aircraft which is comparable with contemporary aircraft in use around the world.
DARE has forged synergetic partnerships with leaders from private industries like M/s TCS and M/s ComAvia to leverage the best in knowledge and the latest in technology. With this upgrade project DRDO, HAL, ADE, IAF, CEMILAC and DGAQA has showcased the expertise that exists within the country for completing complex and challenging task of aircraft upgrade.
