1.ISRO
successfully Tests India's Largest Cryogenic Engine For 400-Ton Rocket.
Indian Space
Research Organisation (ISRO) successfully tested India’s largest Cryogenic engine.
The Indigenously developed cryogenic engine is capable to launch four ton class
satellites in Geosynchronous Orbit and this will be used in GSLV (Geosynchronous
Satellite launch vehicle) Mark III rocket.
It was successfully Ground tested its cryogenic upper
stage engine for GSLV Mark III at its liquid propulsion complex at Mahendragiri
in Tirunelveli, Tamil Nadu.
India is now become 6th country to acquire
this technology after two decades of hard work as the technology was denied
to India by Russia under pressure from the US. Other countries which
have this technology are Russia, USA, Japan, China and France.
About Cryogenic Engine:
'Cryogenic is the study of
substances at very low temperature in which gases like nitrogen, hydrogen and
oxygen become liquid at minus 150 degree or less.
'This is the reason we called
this as cryogenics engine, which use liquid hydrogen and oxygen as fuel that
are stored at minus 253 degrees and then ignited to burn at plus hundreds of
degrees centigrade .
'Cryogenic Engine was first
used by US in 1963. India took almost 20 years to develop Cryogenic Engine.
About
Geo-Synchronous Orbit:
Geo-synchronous
orbit is located 35,786 kilometers(22,236 miles) above Earth’s Equator which is
ideal site for monitoring communication, weather, and surveillance.
2.Indian
Coast Guard Ship Ayush was commissioned
Indian Coast Guard Ship Ayush was
commissioned by vice admiral A R Karve flag officer Commanding-in-chief ,
southern Naval Command, Vishakapatnam.
Ayush was the last in the
series of 20 fast patrol vessels (FPVs) which is built by M/S Cochin Shipyard
Ltd which is a part of coast guard’s plan to expand
operation in coastal Region.
About Ayush:
Ayush was designed and
developed indigenously by M/s Cochin shipyard ltd. The 50-metre FPV, Ayush is
equipped with state-of-the-art weaponry, communication and navigational
equipment. It is propelled by 3 advance diesel engines coupled with 3 Rolls
Royce jets to achieve max speed of 33 knots and has an endurance of 1500
nautical miles at economical speed of 14 knots.
This ship will be helpful for
safeguard the coastal region and other missions like surveillance, search and
rescue, interdiction and maritime law enforcement.The ship will be based at
Krishnapatnam.
