*Analysis: Internationally, a project for one year takes ten fold longer in India. Decisions are taken at a snail pace and time is wasted on unneccessary red tape bureaucracy. Defense procurement system is politically corrupt, as an example urgently needed Hawk 132 advanced jet trainers for Indian Air Force, which took 30 odd years to acquire at the cost of hundreds of young Indian Air Force pilots life.
India is the largest democratically governed country in the world as is an examplery system for other nations to follow suit, but at the same time the system is a curse with too many voices and noises, NO ACTION. India should have for some period a system of administration similar to China, which is straightfoward with no two way decision making that would benefit for the betterment of the country at large.

(NSI News Source Info) NEW DELHI, India - July 8, 2009: India's 20-year, nearly $500 million effort to develop a homegrown engine for the Light Combat Aircraft (LCA) has come to a standstill with the Air Force rejection of a co-development offer from France's Snecma.
The Indian Light Combat Aircraft (LCA) is the world's smallest, light weight, multi-role combat aircraft designed to meet the requirements of Indian Air Force as its frontline multi-mission single-seat tactical aircraft to replace the MiG-21 series of aircraft. The delta wing configuration , with no tailplanes or foreplanes, features a single vertical fin. The LCA is constructed of aluminium-lithium alloys, carbon-fibre composites, and titanium. LCA integrates modern design concepts and the state-of-art technologies such as relaxed static stability, flyby-wire Flight Control System, Advanced Digital Cockpit, Multi-Mode Radar, Integrated Digital Avionics System, Advanced Composite Material Structures and a Flat Rated Engine.
The LCA design has been configured to match the demands of modern combat scenario such as speed, acceleration, maneuverability and agility. Short takeoff and landing, excellent flight performance, safety, reliability and maintainability, are salient features of LCA design. The LCA integrates modern design concepts like static instability, digital fly-by-wire flight control system, integrated avionics, glass cockpit, primary composite structure, multi-mode radar, microprocessor based utility and brake management systems.
The avionics system enhances the role of Light Combat Aircraft as an effective weapon platform. The glass cockpit and hands on throttle and stick (HOTAS) controls reduce pilot workload. Accurate navigation and weapon aiming information on the head up display helps the pilot achieve his mission effectively. The multifunction displays provide information on engine, hydraulics, electrical, flight control and environmental control system on a need-to-know basis along with basic flight and tactical information. Dual redundant display processors (DP) generate computer-generated imagery on these displays. The pilot interacts with the complex avionics systems through a simple multifunction keyboard, and function and sensor selection panels. A state-of-the-art multi-mode radar (MMR), laser designator pod (LDP), forward looking infra-red (FLIR) and other opto-electronic sensors provide accurate target information to enhance kill probabilities. A ring laser gyro (RLG)-based inertial navigation system (INS), provides accurate navigation guidance to the pilot. An advanced electronic warfare (EW) suite enhances the aircraft survivability during deep penetration and combat. Secure and jam-resistant communication systems, such as IFF, VHF/UHF and air-to-air/air-to-ground data link are provided as a part of the avionics suite. All these systems are integrated on three 1553B buses by a centralised 32-bit mission computer (MC) with high throughput which performs weapon computations and flight management, and reconfiguration/redundancy management. Reversionary mission functions are provided by a control and coding unit (CCU). Most of these subsystems have been developed indigenously.
The first prototype of LCA rolled out on 17 November 1995. Two aircraft technology demonstrators are powered by single GE F404/F2J3 augmented turbofan engines. Regular flights with the state-of-the-art "Kaveri" engine, being developed by the Gas Turbine Research Establishment (GTRE) in Bangalore, are planned by 2002, although by mid-1999 the Kaveri engine had yet to achieve the required thrust-to-weight ratio.
An Indian Air Force official said the service now will have to search for an off-the-shelf engine overseas to power the aircraft.
India's Gas Turbine Research Establishment (GTRE) was developing the Kaveri engine to power the LCA. Trying to integrate nearly 16,000 parts and subsystems became too complicated and in 2005, the Kaveri engine caught fire when it was first tested on board a Tupolev-16 aircraft in Russia.
GTRE began looking for co-development partners, and after an international tender was released in 2007, NPO Saturn of Russia and Snecma of France were invited to participate but only Snecma of France was short-listed.
GTRE has developed nine prototypes of the Kaveri, but the engine was found to be heavier than the required 8.5 tons and provided less thrust than needed to power the LCA, according to a GTRE scientist.
The first lot of 40 LCAs being introduced, beginning in 2010, will be powered by the GE 404 engine, but the next batch of aircraft will include several features added by the Air Force that increase the weight of the aircraft by 2 tons. The GE 404 will not be powerful enough to fly the heavier plane, the Air Force official said.
New LCAs with bigger engines will be inducted at a later stage. The EJ 200 engine of Eurojet Turbo of Germany and higher thrust GE 414 engine are the two main contenders.
Both Eurojet Turbo and General Electric have given demonstrations of their engines.
