HAL Tejas Tejas is Indian Light Combat Aircraft fighter Jet developed by Hindustan Aeronautics Limited. First I want to tell you that Tejas is developed to replace MIG- 21. The meaning of Tejas is Radiant in Sanskrit.
TEJAS is a single-seat, single-engine, lightweight, high-agility supersonic fighter aircraft. The LCA TEJAS can speed upto Mach 1.4 and is capable of carrying assorted weapon load along with dropping tanks up to four tons. It has some of the latest avionics and digital flight control systems. The Tejas, presently is powered by American General Electric Engine. The HAL TEJAS is designed with a single vertical fin with no tailplanes or foreplanes and has a delta wing configuration.

The aircraft is also fitted with a night vision compatible glass cockpit with Martin Baker (UK) zero-zero ejection seats. The aircraft’s electronic warfare suite, developed by the Advanced Systems Integration and Evaluation Organisation (ASIEO) of Bangalore, includes a radar warning receiver and jammer, laser warner, missile approach warner, and chaff and flare dispenser. The LCA’s design has been configured to match the demands of modern combat scenario such as speed, acceleration, maneuverability and agility.

Now I like to post the comparative analysis between Tejas and J-17 (pakistan+china) by Mr. Gurung Kalanidhi., Written Sep 1, 2015
These two aircraft follow a similar timeline of development. But, the similarity ends there. The LCA Tejas and JF-17 were designed with very different end applications in mind. For, India the Tejas was designated to be an aircraft which was to drive the technology influx into its fledgling aerospace industry. From the onset, the emphasis was not on costs but usage of cutting edge technology. This is not the case for Pakistan. For Pakistan the JF-17 is a much needed breather to replace its old fleet of Mirage III and Chengdu J-7 Fighters. Also, the design of these two aircraft is completely different. IAF has always been vehement about latest technology and this was the driving factor behind the design of the Tejas whose design has evolved around the timeline. But for Pakistan, this is not the case. The JF-17 is essentially a redesigned version of the Chengdu J-7(MiG 21 clone). Apart from the addition of LERX on the design and clipped delta wings, there’s not much of an improvement. On the other hand, the airframe of the Tejas is a beauty. Designed by ADA, it is a complex delta wing with an efficient leading edge blending for smooth handling at higher AoAs (Angle of Attack). Even the materials used for construction show the difference in the thought process. While ADA and HAL had from the onset been keen on keeping the weight low by using Carbon composites (at which India is now a pro), the CAC designed and PAC assembled JF-17 uses only aluminium alloys which add quite some weight to the design.
