8/20/2007 - The twin-engine Dhruv helicopter built by
HAL (Hindustan Aeronautics Limited), and re-engined
with the Turbomeca Ardiden 1H, successfully made its
maiden flight on August 16th 2007, in HAL’s helicopter
division, Bangalore, India.
The representatives of the Ministry of Defence and
many operators present at the occasion were given a
clear demonstration of the aeromechanical behavior and
the performances of this new-generation engine.
Ashok K Baweja, HAL’s Chairman declared: "After the
TM333 2B2, the Shakti engine will further enhance the
reliability and performances of the Dhruv under
demanding flight conditions."
This maiden flight is to be followed by EASA
certification of the Ardiden 1H, planned for the end
of the year.
The Ardiden was built to provide a response for
missions with the most demanding hot weather and
altitude requirements. Developed in cooperation with
Hindustan Aeronautics Limited (HAL) under an
industrial partnership contract signed in February
2003, this engine combines simplicity, high
technology, robustness and modernity, all for an
ownership cost far lower than our competitors offers.
The Dhruv features a take-off weight of 5,500 kg. To
begin with, it will be operated by the Indian armed
forces. In the frame of the contract entered into in
February 2003, several hundred engines will be
produced over the next 10 years.
The new turboshaft engine is a further addition to the
Turbomeca range, already the broadest on the market.
Two turbomeca engines for the Dhruv... The TM 333
2B2, which won its DGAC (French Civil Aviation
Authority) certificate in December 2001, was also
chosen by HAL to power the Dhruv. It has a take-off
power of 1,100 shp. With its simple modular
architecture, it boasts the threefold advantage of
reliability, easy maintenance and low fuel
consumption. So far, HAL has ordered several hundred
engines. Today, over 200 engines have been delivered.
The Shakti, fundamentally different in design, offers
a take-off power of 1 200 shp, as well as an emergency
power superior of 30% compared to the TM333 2B2. The
Shakti will have a TBO within a range of 3 000 to 6
So whatever the mission the Dhruv is called on to
operate, it will have two engines ideally suited to
it, while assuring its performances both at altitude
and in hot weather.
The Ardiden 1H engine will be certified in India
under the name of “Shakti”.
