ISRO successfully conducts scramjet engine test

The Indian Space Research Organisation (ISRO) successfully test launched scramjet engine on Sunday from from Satish Dhawan Space Center (SDSC) in Sriharikota, Andhra Pradesh.
The rocket took off at 6am.

The scramjet engine, used only during the atmospheric phase of the rocket’s flight, will help in bringing down the launch cost by reducing the amount of oxidiser to be carried along with the fuel.

The launch of weather satellite INSAT-3DR with the geosynchronous satellite launch vehicle (GSLV-MkII) has been postponed to September, a senior official said on Saturday.

Earlier P Kunhi Krishnan, director of SDSC had said the Indian weather satellite will be launched on August 28 which has now been postponed to September 8.

Queried about the change in launch plan Krishnan said: “While carrying out the tests there was a technical issue found with a satellite component. It has been sorted out now and hence the delay.”

He said the GSLV rocket that would carry the weather satellite INSAT-3DR is fully assembled.
The weather satellite will be mounted on to the rocket in three to four days.

According to officials, the ISRO will launch ScatSat -- a weather monitoring and forecasting satellite -- with polar satellite launch vehicle (PSLV) end of next month.

The Indian satellite will be a co-passenger to an Algerian satellite.

Both the satellites will be put into different orbits. So the fourth engine of the rocket will be switched off after ejecting ScatSat first. Then after a gap of around 30 minutes, the engine will be switched on and put the Algerian satellite into its intended orbit.

Great news we are now fourth country to have this technology. As long as these guys are there India's future is bright. [emoji106]

I wish there were some medals for intelligence also in Olympic. We will then get quite a few [emoji6]

ISRO makes u proud everytime :tup

why are scramjets important for ISRO?

ISRO currently uses rocket launch vehicles like the PSLV to deliver satellites into orbit. PSLVs are expendable, meaning that can only be used once, and are designed to carry both fuel and oxidizer with for launch. Scramjets use ambient air to burn fuel, thus saving the need to carry an oxidizer – thus increasing the payload of a craft. ISRO claims that using Avatar for satellite launches will cut down launch costs by half. Since there are no rotating parts in a scramjet, the chances of failure are also measurably reduced.

ISRO’s reusable launch vehicle platform, called Avatar, is a concept that is capable of carrying out satellite launches – takes off vertically and lands back on a runway. The spacecraft is designed to use ramjets and scramjets for thrust. Each of these engines will be used in different stages of the flight – with ramjet used at lower speeds, scramjet at hypersonic speeds and cryogenic engines when the craft reaches the edge of the atmosphere.
