Hindustan Aeronautics (HAL) chairman N R Mohanty has
stressed the need for multi-organisational team effort
to achieve self-reliance.
a two-day national seminar on aerospace and related mechanisms
(ARMS 2002), organised by Vikram Sarabhai Space Centre
(VSSC) here, he said any country that wants to improve
the quality of life of its people should pool its resources
and foster the growth of organisations that bring technologists
director G Madhavan Nair presided over the function.
lauded the mechanism professionals of defence, space,
aerospace and industry for making India self-sufficient
in critical areas of aerospace and related mechanisms
without which Indias success in these areas
could not have been achieved. Mechanisms play a major
role in aircraft manoeuvres, satellites and launch vehicles,
and weaponry. There is a need for perpetual innovation
in the various mechanisms applied for flight control,
staging, ejection and deployment of weapons to keep pace
with worldwide developments.
has crossed several milestones during the recent past
in its stride towards creating its own place among the
leading nations of the world. The successful flights of
the SLV, ASLV, PSLV, GSLV and the light combat aircraft
(LCA) were a few of these in which aerospace mechanisms
developed by the country were effectively deployed.
aerospace industry normally lead in the development and
application of cutting-edge technologies since aircraft
and spacecraft structures and systems need to function
with very high reliability and demanding customer specifications,
Mohanty added. Such technological achievements are
the result of extensive research and the integration of
a multitude of engineering disciplines by aerospace scientists
need for better understanding and application of these
mechanisms has resulted in the emergence of fly-by-wire
deployment control of spacecraft appendages, jettisoning
mechanisms, integrated flight control systems, nose-wheel
steering and internal locking in actuators among other
things, he said.
described the LCA as one of the few aircraft in the world
to have integrated flight control system in addition to
several other advanced systems. The flight controls act
in coordination with hydraulics, multiple electrical supply
and other systems.
LCA also employed steer-by-wire for nose-wheel steering.
Several mechanisms which combined complexity, space constraints,
safety and reliability factors have been developed by
HAL. They include the mechanical canopy locking systems
in open and closed conditions, the landing gear retraction
mechanism, the wheel toe-out mechanism for ship deck helicopters
and their hydraulically operated quick mooring system
used to anchor helicopters, he said.
VSSC director said it was Indian President A P J Abdul
Kalam who had laid the foundation for the evolution of
aerospace mechanisms in the late sixties in the Bishops
House of the St Magdaline Church at Thumba, Thiruvananthapuram,
which was the first abode of space technology in India.
It was from that stage that it developed to the
present capability of international standards.
R Sridharamurthy, the executive director of Antrix, the
commercial organ of Indian Space Research Organisation,
inaugurated the exhibition which was organised in connection
with the seminar. Defence Research and Development Laboratory
director Y Prahlada released the proceedings of the seminar
and Launch Vehicle Programme Office Director D Narayana
Moorthy released the souvenir brought in connection with
VSSC associate director R V Perumal welcomed the gathering
and C B Kartha, the chairman of the local organising committee,
proposed the vote of thanks. Some 400 scientists, academicians
and industrialists from all over India attended the seminar.
