Update On India’s Kaveri Jet Engine


India has no fixed plans to fully develop the indigenous Kaveri
fighter engine for the Hindustan Aeronautics Ltd (HAL) Tejas aircraft.

“The Defence Research Development Organisation [DRDO] has not
fixed any timeframe to fully develop the Kaveri Aero Engine for the
[Tejas],” says defence minister AK Antony.

The announcement is the closest New Delhi has come to abandoning
the long-delayed engine programme, which has suffered from major
performance issues and cost overruns.

Antony noted that the Tejas requires an engine capable of
producing 90kN (20,200lb) of thrust, but the “Kaveri does not fully meet
this requirement.”

“Therefore, it has been decided to use variants of Kaveri engine
to power unmanned air vehicles and also for marine applications,” he
says.

He adds, however, that a Kaveri jet engine could be tested aboard a
Tejas Mk 1 in another three years. This suggests that major issues
still need to be ironed out before the engine is married to a manned
fighter.

Antony made the comments in a written reply to a question in parliament.

The Tejas Mk I uses the General Electric F404 power plant, while
the planned Tejas Mk II will use the General Electric F414.

In March, Antony told parliament that the Kaveri’s development
cost was Rs28.39 billion ($528 million), nearly 10 times greater than
the Rs3.83 billion originally allocated.
