‘ISRO working on a new-generation launch vehicle’

[SR-91]

The Indian Space Research Organisation (ISRO) is working on a new-generation launch vehicle, which can orbit a four-tonne communication satellite from Indian soil, according to N. Prahlad Rao, Director, Satellite Communications and Navigation Programme, ISRO.

He was speaking at the graduation day of the National Institute of Engineering (NIE) here on Saturday.

Mr. Rao said ISRO had established expertise in providing end-to-end solution from drawing board to placing the satellites in orbit. Almost all components required to assemble the space systems were developed in-house. “Only some payload components are imported, but the journey has not been easy,” he said.

“In case of cryogenic engine development, the cutting-edge technology was developed from scratch, but it took more than the anticipated time. However, ISRO ultimately succeeded in realising this crucial technology and with these successes in the background, it was working on a new generation launch vehicle to carry and orbit a 4-tonne communication satellite,” he said.

Describing the forthcoming projects, Mr. Rao said the coming year was going to be one of navigation as GAGAN, a system-based GPS augmentation was already operational and would bring in improvements in the operation of civil aviation routes.

“India’s regional navigation programme, IRNSS, is going to be operational and this will be a system operating independent of any foreign systems like GPS and will make India self-reliant in this area,” according to Mr. Rao. He said there were around 25 spacecraft orbiting earth and providing services in the area of communication, meteorology, remote sensing and navigation and the benefits of these efforts are already reaching common man in this country. “It is taken for granted that any point-to-point communication is just a push button away. But behind the scenes, ISRO communication satellite is providing the crucial connectivity. When cyclone Phalin made landfall in Odisha recently, not one life was lost, thanks to the contribution from space technology, which was playing an active role in disaster management,” Mr. Rao added.

India need to master semi-cryogenic stage to be a real player in launch vehicle business.

Wrong image ...... The news article is about GSLV MK3 and image shown is of ULV .

 

[Gessler]

Man...these rockets GSLV Mk-2/3 are massive scientific & engineering efforts by our scientists. Truly worthy of congratulation
and admiration.

..when is the lift off for Mark-II/III??

..when is the lift off for Mark-II/III??

GSLV MK2 has already been successfully flown with indigenous cryogenic engine CE-7.5 .

GSLV MK3 with mock third stage will have it's first sub-orbital launch after completion MOM mission this year itself .

MK3 will become fully functional in 2017 .... The only thing left to materialize is the cryogenic engine CE-20 .

and what is that exactly

 

[vsdave2302]

and what is that exactly

It is an engine which uses -250* C liquid hydrogen nad oxygen as fule. They are highly efficient ad so they have long burn tine. they are used in rocket to improve efficiency in term of High load carrying, greater orbit etc.

nope this is the link shown in the News might be ISRO insisting to show this one rather GSLV mk-3; and well Whether the GSLV mk-3 is going to be launch this yr or not, i heard about july, though it would not full test but test the crue cabin, any news?

then its cryogenic what is semi-cryogenic?

Its 150 degree celsius....

A Cryogenic engine is one in which both the fuel and oxidizer will be cryogenic .

It uses liquid hydrogen and liquid oxygen .

A Semi-cryogenic engine is one in which the fuel is earth storable while oxidizer is cryogenic .

It uses RP-1 ( Rocket Propellant-1 or Refined Petroleum-1) which is a highly refined form of kerosene and Liquid Oxygen .

It's not ISRO insisting instead it must be idrw messed up reporting .

They have postponed it to concentrate on MOM mission . So launch will take place after september .

[vsdave2302]

then its cryogenic what is semi-cryogenic?

Semi cryogenic uses liquid kerosine and oxidizer at a few degree above absolute zero (-273*) as the fuel. They are more efficient than other engines but less efficient that cryogenic engine.
