Single engine, delta wing...probably one of the Mirage's would do fine, I suggest Mirage III.

Well I did use the M III shape and the metal finish, but it doesnt look tthat great.
The intakes are under the wing root, not along the wing root as in the Mirage.
The wing is cranked, the radome is rounder, the tailplane is bigger.
Are these changes possible?

Thanks,

Altering the shape itself, sadly no...just a skin that's all we can do :(

You have taken inot account, havent you, that the pics of this aircraft are simply colored this way for test and promotion?... The combat texture for this aircraft would either be in the all grey finish of the MiGs, or the haze blue cammo fo the Mirage 2000...

It definately would NOT be in the colors that are present in the pics you linked to...

Yes CAG,
However the Tejas is not slated to fly in IAF colours and camo for atleast 4-5 years. Till the atleast the basic demo aircraft pattern will be followed.

Hi,
Cent glad to!

LCA Specifications

Type: All weather air-superiority fighter and light close support aircraft.

Variants: Single-seat multi-role fighter.
Dual-seat combat-capable trainer.

Design Features: The airframe is based on an oval-section fuselage with a shoulder-set double delta wing. It has a compound sweep on its leading edges, which exhibit considerable twist between their inboard & outboard ends. The moving surfaces comprise three-segment flaps on the leading edge and two-section trailing-edge elevons (or elevators). All control surfaces are operated via a full quadruplex digital FBW control system, designed jointly by Lockheed Martin Electronics and ADE. Composite materials, which amounts for over 30% of the weight, and aluminum-lithium alloys have been used to keep the weight down. A special type of material - CFRP (Carbon Fibre Reinforced Plastics) - is used in the wings, control surfaces and vertical tail. Titanium alloy is used near 'hot spots' such as the engine. A brake parachute improves landing field performance.

Avionics: The LCA will have a multi-mode pulse-Doppler radar and FLIR (Forward-Looking Infra-Red). The cockpit is equipped with HOTAS, HUD and two color multi-function CRTs compatible with the use of NVGs. They are integrated with other elements of the electronic suite such as the INS via a central computer and three MIL-1553B data-buses. The LCA has a Utility Systems Management System to monitor the health of each of its systems and optimize their performance. For maintenance the LCA has 500+ Line Replaceable Units (LRUs), each tested for performance and capability to meet the severe operational conditions to be encountered.

Engine: LCA prototypes will feature a G.E. F404-F2J3 turbofan rated at 18,097 lbs. of thrust with afterburning. Production aircraft will have a Kaveri GTX-35VS turbofan rated at 20,200 lbs. of thrust with afterburning. The engine is operated by a Dowty/Smiths FADEC (Full Authority Digital Engine Control System).

Fuel Capacity: Internal fuel capacity - 3000 litres. The centreline and the two-inner hard points under each wing, can carry five 800 litres fuel tanks. The aircraft also has an in-flight refueling probe fitted on the starboard side of the forward fuselage to increase range.

Maximum Range: ?

Maximum Speed: Mach 1.7

Service Ceiling: 50,000 feet.

G Limits: +9/-3.5

Armament: The LCA is fitted with an internally mounted GSh-23mm twin barrel gun with 220 rounds of ammunition. Seven external hard points, can carry air-to-air missiles, air-to-surface missiles, anti-ship missiles, rocket launchers and ECM pods. The aircraft is designed to use armament from Western, Russian and Indian sources.

Maximum External Stores Load: 4000kg (8818 lbs.)

Self Defence: A RWR system, jammer and chaff & flare dispensers.

Outlaw..

"The only true air superiority is a tank parked in the middle of the runway"

Not if I have a JDAM with your coordinates! Tanks are nothing but mobile coffins to aircraft...

Cent you are right on with those F-16 stats, however the Blk 40s are now also capable of those laods since they have all been re-engined to Blk 50 standard, plus some harpoint reinforcemnts were added...
