INDIGENOUS DEVELOPMENT OF LINE REPLACEABLE UNITS (LRU’s) FOR LCA-TEJAS


LIGHT COMBAT AIRCRAFT (LCA) (Tejas)


Development Phase
 
 
Tejas is a single engined, light weight, highly agile, multi-role supersonic fighter. It has quadruplex digital fly-by-wire Flight Control System (FCS) with associated advanced flight control laws. The aircraft with delta wing is designed for ‘air combat’ and ‘offensive air support’ with ‘reconnaissance’ and ‘anti-ship’ as its secondary roles. Extensive use of advanced composites in the airframe gives a high strength to weight ratio, long fatigue life and low radar signatures. Aeronautical Development Agency is the designated project manager for the development of LCA.

LIGHT COMBAT HELICOPTER (LCH)

 
 
Light Combat Helicopter (LCH) was proposed to meet IAF’s requirement of a dedicated light helicopter for combat operations. LCH will have maximum possible commonality with ALH. LCH with a narrow fuselage will have pilot and co-pilot/gunner in tandem configuration incorporating a number of stealth features, Armour protection, Night attack capability and crashworthy landing gear for better survivability. The major features of LCH are:
 
 Glass Cockpit
 Crashworthy under floor structure
 Crashworthy fixed tricycle type with tail wheel landing gear
 Canted flat panels for low Radar Cross Section
 Integrated Dynamic System
 Hingeless Main Rotor / Bearingless Tail Rotor
 Anti Resonance isolation system
 Integrated Avionics and Display System (IADS)
 IR Suppressor
 20mm Gun, Rocket & Missiles

JAGUAR DARIN-III Upgrade

 
• Aircraft upgraded to DARIN-III standard would feature following equipment/systems in addition to those integrated as part of the recent strike aircraft produced (DARIN II + additional systems) :
• Modified avionics Architecture
• New cockpit with dual SMD on single seater A/C
• Integration of MULTI MODE RADAR on single seater Aircraft
• Engine and Flight Instrument system/Integrated Standby Instrument system (EFIS/ISIS) Integration to replace existing electro-mechanical flight instruments and/or engine instruments.
• Solid State Flight Data Recorder and Solid State Video Recording System
• Additional functionalities related to display, data transfer and Auto Pilot
• New Weapons
• Development activities would involve major structural modification to the airframe to accommodate the radar (on the nose cone of Strike aircraft). On the Avionics front Mission computer software development, new cockpit design, radar integration and solid state video recording system is to be addressed. Modification will also be required to be carried out on the air-conditioning system to meet the equipment cooling requirements.

 
Mirage Upgrade

 
• Mirage 2000 Upgrade is proposed in two Phases:
  • Phase-1: Development for Initial Operational Clearance (IOC) & Supply of IOC Equipment by French OEMs (Thales & Dassault)
  • Phase-2: Development for Final Operational Clearance (FOC) and series upgrade of the fleet by HAL:
    • Integration of Buyer Furnished Equipment (BFE)
    Six subsystems viz. Laser Designation Pod (LDP), Air Combat Maneuvering Instrumentation (ACMI) pod, Helmet Mounted Display System (HMDS), Crystal Maze missile (CM), BDL-CMDS and Operational Data Link (ODL- provision only).
    • Design and development of HAL Mission computer
    • Upgrade of two IOC standard aircraft to FOC standard.
    • Series Upgrade of aircraft.
FIFTH GENERATION FIGHTER AIRCRAFT (FGFA)

 
 

The proposed FGFA will have air combat superiority, high tactical capability, group action capability in the regions even with poor communication support. The aircraft will have advanced features like

  • Increased Stealth
  • Supersonic cruise
  • Data link and network centric warfare capability.

FGFA will be co-developed with Russians. Sukhoi Design Bureau (SDB) has been selected as the Russian agency for this development project.

MULTI-ROLE TRANSPORT AIRCRAFT (MTA)

 
 
  • Co-development and co-production of Multi-role Transport Aircraft, jointly by Russian partners and HAL, is being launched to meet the requirement of Russian and Indian Air Forces.
  • The aircraft will be designed for the roles of a 15-20 ton Cargo / Troop transport, Para trooping / Airdrop of supplies including Low Altitude Parachute Extraction System (LAPES) capability. It will be configured such that all types of cargo can be transported and the aircraft would be capable of operating from semi prepared runways.

INDIAN MULTI ROLE HELICOPTER (IMRH)

 
 
  • Co-Design and co-production of a 10 Ton class Medium Lift Helicopter is proposed to be taken with an international helicopter manufacturer to meet the requirement of the 3 Indian Defence Services. This approach is taken to shorten the development timeframe.
  • The Helicopter will be powered by twin engines and will feature blade folding option for ship deck operations. The variant for Army/IAF will support Air assault, Air Transport, Combat logistic, Combat search & rescue and casualty evacuation operations. The naval variant will be developed for Anti Submarine Warfare and Anti Surface Vessel Strike roles
