LCA 2005 Aero India
A full scale mockup of the production standard LCA in its estimated combat camouflage scheme. While this setup is supposed to reflect PV-2, higher up sources indicate that the latter would adorn the same overall-white scheme as worn by the other three prototypes while other sources say otherwise. The serial number "KH-200X", certainly offers no additional clues. At some angles, resemblance to the SAAB Gripen is strong. The color is not the IAF-standard low-viz gray but does look much better.
The mockup is accurate down to RWR fairing on the tail. Whether this makes up for the lack of an actual prototype on static display, as exhibited 2 years ago, is a subjective question. For whatever reason, the mockup didn't attract a flood of people, which was good as far the photographer was concerned. The "TEJAS" lettering on the nose, was first painted on TD-2, but now seems to have become standard artwork. Note the extremely recessed carriage of the 800 liter drop tank.
The mockup is depicted with a loadout of Astra BVRAAMs and R-73E WVRAAMs, both mounted on oversize pylon interfaces. It is not known if the Astra's design evolved to what is seen here or whether it was a mere inaccuracy on the fabricator's part. Either way, this is one of the better looking AAM designs ever seen, with the fins being placed well forward and the body thickness varying over the length.
A scale model with the same scheme was on display at the ADA stall. As before there was also an N-LCA model, but this time with a telescopic undercarriage. The earlier scale models seem to have wound up as displays on the ADA and ASTE campuses.
The engineering model of the LCA's Multi-Mode-Radar (MMR), complete with IFF dipoles. The digital signals processor (DSP) and radar computer are not separate and have been integrated into a single, larger LRU. The antenna is 650 mm wide, larger than the Phazotron Zhuk-ME's 624 mm antenna, although it certainly doesn't look it at first glance. AUW of the entire set is just 130 kg.
A rather improved exhibit of the the Kaveri engine, intended to power the LCA at later stages. Flight certification is only expected around the time the LCA completes FOC. As with other parts of the LCA programme, GTRE has used CFD codes to analyze flow in the compressor, combustor, bypass ducts, afterburner etc.
