3. INTRODUCTION
▪ When there is no fighter crafts in the wing section of the Indian air force the
HALTEJA’ S stood on the side of the combat.
▪ In this presentation the complete specifications have been evaluated and
described as per the knowledge.
▪ The HALTejas is an Indian single-seat, single-jet engine, multi-role light
fighter designed by the Aeronautical Development Agency (ADA)
and Hindustan Aeronautics Limited (HAL) for the Indian Air Force and Navy.
▪ The main objective of this presentation is to replace the
▪ It came from the Light Combat Aircraft (LCA) programme, which began in
the 1980s to replace India's ageing MiG-21 fighters. LCA was officially named
"Tejas" in 2003, meaning "Radiant" in Sanskrit by the then Prime
Minister Shri Atal BihariVajpayee.

19. PROPULSION SYSTEM OF TEJA LCA

20. PROPULSION SYSTEM DEVELOPMENT
▪ Early on, it was decided to equip prototype aircraft with the General Electric F404-GE-
F2J3 afterburning turbofan engine
▪ In 1998, after Indian nuclear tests, US sanctions blocked sales of the F404
▪ Later it was given to the kaveri development.
▪ It fails to supply a engine which can fly at higher altitudes .
▪ Later for technical assistance it contacted the French engine company scecma
▪ Using Snecma's new core, an uprated derivative of the Dassault Rafale's M88-2 engine,
providing 83–85 kilonewtons (kN) of maximum thrust was being considered by DRDO.
▪ In November 2014, the DRDO was submitting documents to cancel development of
Kaveri.

21. DEVELOPMENT OF ENGINE
▪ In 2008, it was announced that an in-production power plant
would have to be selected; this was required to be in the 95 to
100 kilo newton (kN) (21,000–23,000 lbf) range to execute
combat maneuvers with optimal weapons load.
▪ After evaluation and acceptance of technical offers for both
the Eurojet EJ200 and the General Electric F414, the commercial
quotes were compared in detail and GE's F414 was declared as
the lowest bidder.
▪ The deal covered the purchase of 99 GE F414 engines, an initial
batch will be supplied directly by GE and the remainder to be
manufactured in India under a technology transfer arrangement
