DRDO to test indigenous scram jet engine next year

NEW DELHI Defence Research and Development
Organisation (DRDO) will test the indigenously
developed scram jet engine next year, according
to DRDO chief VK Saraswat.
"We have demonstrated the performance of a
scram jet engine operating at Mach six speed (six
times the speed of sound)," he said in an
interview given to Doordarshan.
Theoretical projections place the top speed of a
scramjet between Mach 12 (15,000 kmph) and
Mach 24 (29,000 kmph), according to Wikipedia.
The fastest air-breathing aircraft is a SCRAM jet
design, the NASA X-43A, which reached Mach
9.8. For comparison, the second fastest air-
breathing aircraft, the manned SR-71 Blackbird,
has a cruising speed of Mach 3.2.
After the successful launch of Agni-5 Inter-
Continental Ballistic Missile (ICBM), India is all set to
develop reusable rockets which will combine the
technologies of both ballistic and cruise missiles.
On the range of Agni-5 missile, which was
successfully test-fired recently off Odisha coast,
he said with moderate modifications, "it can be
extended to any range which is of our interest."
On the technological capability available with the
agency, he said: "DRDO has built the necessary
technologies, production infrastructure and
design capability for developing a booster or a
sustainer.
"We have the capability to develop a re-entry
nose cone which can withstand higher
temperature and velocity."
Reacting to reports that India does not possess
sufficient indigenous technology for missile
guidance systems, Saraswat said Agni-5 has
used a completely indigenous and high precision
missile guidance system with "0.001 degrees of
per hour accuracy."
On criticism that DRDO sometimes does not live
up to expectations, he said the agency was as
good as its counterparts in advanced countries.
"The Light Combat Aircraft (LCA), F-18 and
Eurofighter took similar number of years and cost
wise they were three times more than what we
have put in our LCA," he said.
On the development of the Kaveri engine,
Saraswat said it has performed well and was,
"flown on an IL-76 aircraft in Russia for 55 hours
of successful flight. We are going to upgrade it so
that it can be used in India's LCA Mark-II and
future systems."
