Locked inside a pigment of her imagination,

A speck of hope for a train to stop at her station,

Her shackles tell us the story of her past,

An eternal struggle until she breathes her last.

Mazaar se guzartey hue, musafir ne sunehra farishta dekha

Bikhrey mazaar mein jannat ka ek khwaab dekha

By Parthsarathi Trivedi – February 5th ’08

Veiled behind the darkness no light reaches his eyes,

Every time he sees her, his iron heart cries,

She looks at him, her thoughts unchanged,

He wonders where her love had waned

Hidden behind a shield of ignorance to suffering she was blind,

No matter how much he searched, it was vision he could never find,

She glimpsed at him for one last time before confirming the harness,

Just another shadow in the darkness.

Parthsarathi Trivedi

Trains subways cars people, an era of confusion

Humans dominating Mother earth, its all an illusion

Forgetting who they are in a desperate attempt to live

Not caring for their brothers and sisters unwilling to take or give

The only things these mortals take are lives

Their stagnant apartments cover the sky, repugnant beehives

Nothing can extricate the ego that resides within their mind

Conceited fools they are, to honesty they are blind

The Sunday tabloid, broadsheets, just scraps of paper

At neither sorrow nor joy will they ever caper

There she lies, the forgotten Mother

No one giving a damn about the other

India’s second indigenous combat aircraft, LCA or Light Combat Aircraft, is set out to replace the MiG-21 series of the fighter aircraft in the Indian Air Force. The prototype which took off on its first flight in January 2001 is the world’s smallest and lightest multi-role combat aircraft. The design of this supersonic single-seat fighter features short take off and landing, adding performance to maintainability with its delta wing design. A significant characteristic is the absence of any tailplanes or foreplanes but only a single vertical fin, meaning that the LCA features highly advanced flight stability systems. Its   structure is made mostly of Aluminum-Lithium alloys along with titanium and carbon-fibre composites.

Five hundred Line Replaceable Units ensures maintainability, and all major systems and features are being tested to ensure performance and safety. The official flight test program will begin in 2001. The LCA is to be powered by the GTX-35VS or Kaveri engine which is an augmented turbofan design.  This project is under the Department of Defense Research and Development Organization, with principle partner Hindustan Aeronautics Limited, but several national teams and international manufacturers are also working towards the LCA’s development.

These various collaborations have given the LCA state of the art technologies including Fly by wire Flight control system, advanced digital cockpit along with Multi-Mode radar and various other advanced avionics systems. With these advanced avionics along with the hands on throttle and stick (HOTAS) and heads up display (HUD), the pilot’s workload is greatly reduced. The armament on board, controlled by an autonomous targeting system, ensures the LCA always stays a step ahead when it comes to modern warfare. The LCA’s eyes and ears comprise of the laser designator pod (LDP), forward looking infra-red (FLIR) and various other devices that recognize and target hostile bodies. All these complex systems are accessible to the pilot through a simple multifunction keyboard and sensor selection panels.

The brain of the LCA is a digital flight control computer or DFCC, built around 32 bit microprocessors coupled with a failsafe digital fly by wire (FBW) system. The software to be implemented is based on the ADA language and features an advanced electronic warfare suite, further enhancing air superiority. This computer receives sensory information as well as feedback from the various flight control systems. Since the LCA’s flight systems are all electronic, the DFCC’s improved signal processing technology reduces error significantly. The key determinant of effectiveness of the LCA will be based on the MMR; as a signal processor its main duty is to track, scan and identify the enemy. The system has been developed keeping processing speed and targeting priority in mind.

After all the various systems and subsystems were put through rigorous testing, the first prototype rolled out in November 1995. However, the Kaveri engine did not achieve the required thrust to weight ratio till 1999. The LCA, expected to be commissioned by the Indian Air Force between 2003-2005 is going to serve as the frontline tactical fighter plane through the year 2020. This 13.20m (length) by 8.20m(wing span) aircraft, bearing GSh-24 twin-barrel 23mm cannon and 7 hardpoints for various missiles, is expected to roll out of assembly lines in Bangalore estimated at 21 million USD a piece.
